The best power banks always come in handy. Our gadgets have a Murphy’s law-like ability to run out of power at the least convenient moment: as you step on the bus, right in the middle of an important meeting, or just as you get comfortable on the couch and press Play. But with a portable charger in your pocket, you can keep using your devices.

There are hundreds of portable battery packs, and picking one can be confusing. To help, we've spent years working our way through all of them. This obsession started when WIRED reviewer Scott Gilbertson lived off-grid in a vintage RV, powered primarily by solar panels. But even if you're not living in an off-grid solar setup, good power banks will come in handy. The Nimble Champ is our top recommendation for most folks, but you'll find all sorts of alternatives here. Read our Best MagSafe Power Banks guide for Apple-specific portable chargers, and our Best Portable Power Stations guide if you need more power.

Updated May 2025: We added a portable power backpack from Bluetti and an honorable mention for a power bank from OnePlus.

Specs and Features to Consider

There are a few things worth thinking about when you’re shopping for a portable charger.

Capacity: The capacity of a power bank is measured in milliampere-hours (mAh), but this can be a little misleading because the amount of power you get out depends on the cable you use, the device you're charging, and the charging method (Qi wireless charging is less efficient). You will never get the maximum capacity. We try to provide a minimum estimate of what you’ll get in terms of charges for devices.

Charging speeds and standards: The charging rate for devices like smartphones is measured in watts (W), but most power banks list the voltage (V) and the amperage (A). Thankfully, you can calculate the wattage yourself simply by multiplying the voltage and amperage. Unfortunately, getting that maximum rate also depends on your device, the standards it supports, and the charging cable you use. Many smartphones, including Apple’s iPhones, support the power delivery standard, meaning you can use higher-power power banks to recharge the device with no issues. A few phones, such as Samsung’s Galaxy S range, support a supplementary PD protocol called PPS (Programmable Power Supply) that goes up to 45 W. Many phones also support Qualcomm’s proprietary Quick Charge (QC) standard. There are also other proprietary fast-charging standards, but you won’t generally find power banks that support them unless they come from the smartphone manufacturer.

Pass-through: If you want to charge your power bank and use it to charge another device simultaneously, it will need pass-through support. The Nimble, GoalZero, Biolite, Mophie, Zendure, and Sharge portable chargers listed support pass-through charging. Anker discontinued support for pass-through in some of its products because it found that differences between the output of the wall charger and the input of the device charging can cause the power bank to cycle on and off rapidly and shorten its lifespan. Monoprice does not support pass-through charging either. We would advise caution when using pass-through, as it can also cause portable chargers to heat up.

Travel: It’s safe to travel with a power bank, but there are two restrictions to keep in mind when you board a flight: You must have the portable charger in your carry-on luggage (it cannot be checked), and it must not exceed 100 watt-hours (WH). If your power bank has a larger capacity than 27,000 mAh, you should check with the airline. Below that should not be a problem.

Why You Should Avoid Cheap Power Banks

Many years ago, the Samsung Galaxy Note 7 gained notoriety when its batteries caught fire in a series of incidents. There's been a steady stream of similar, though isolated, incidents ever since. However, despite the high-profile coverage of batteries gone wrong, the vast majority of lithium-ion batteries are safe.

The chemical reaction that occurs inside a lithium-ion cell is complex, but as in any battery, there's a negative and a positive electrode. In lithium batteries, the negative is a lithium-carbon compound, and the positive is cobalt oxide (though many battery makers are moving away from cobalt). These two compounds cause a reaction that is safe when controlled and delivers energy to your devices. When the reaction gets out of control though, you end up with earbuds melting in your ears. What changes a safe reaction to an uncontrolled reaction can be any number of things: excess heat, physical damage during use, physical damage during manufacture, or using the wrong charger.

The three basic rules that have kept me safe (thus far) through testing dozens and dozens of batteries are:

Avoiding cheap wall-outlet adapters, cords, and chargers is the most important. These are your most likely source of problems. Those chargers you see on Amazon for $20 cheaper than the competition? Not worth it. They probably got the price down by skimping on insulation, leaving out power-management tools, and ignoring the basics of electrical safety. Price alone is no guarantee of safety, either. Buy from reputable companies and brands.

Then there's heat. Too much of it can cause all manner of problems, both in terms of discharge and in terms of safety. Avoid heat, and pay attention to your batteries when they're charging. If your device gets overly hot when charging, this can be a sign of problems. Similarly, beware of any swollen, bulging, or otherwise misshapen batteries.

Nimble

Amazon (Large)

Nimble (All)

The Nimble Champ topped this list for years, and now its successor is taking over by combining everything that made the original so good and bringing some welcome improvements. At 6.2 ounces, it's one of the lightest on the market. It's smaller than a deck of cards and can deliver 20 watts to charge two devices at once via a USB-C port on either end. While Scott used the original for years, the new version has only been out for a few months, but so far, so good. It feels durable, comes in a snazzy new range of speckled color finishes, and has a bright lanyard loop that makes for easy carrying and helps you pick it out of your backpack. The Pro version is bigger but doubles the capacity (to 20,000 mAh) and has a similar design with two USB-C ports that go up to 65 watts. There's also a smaller version with a 5,200-mAh capacity that tops out at 15 watts.

The other reason we like Nimble best is because of its environmental efforts. Batteries are not environmentally benign. They use lithium, cobalt, and other rare metals whose supply chains are environmentally and socially questionable at best. But Nimble's use of bioplastics and plastic-free minimal packaging at least reduces the environmental impact where it can be reduced. This new version uses 90 percent recycled plastic (up 25 percent from the original) and comes in smaller plastic-free packaging. Nimble includes a 3.3-foot USB-C to USB-C cable in the box.

Anker

Anker

You get style and substance with this versatile power bank from Anker. It boasts a whopping 25,000-mAh capacity and can deliver up to 165 watts to two devices (it tops out at 100 watts for a single device connected via USB-C). I love the rounded edges, the retractable flat 2.3-foot USB-C cable up top, and the clever braided 1-foot USB-C cable that doubles as a carry loop. It has a display to show the remaining battery, charging rate in and out, battery temperature, and health. It takes around two hours to recharge and supports pass-through charging. It fast-charged everything I tested it with, and you can charge four devices at once without a problem.

If you want a compact charger that comes in fun colors and simply slots into the bottom of your phone for a top-up, Anker’s dinky charger is tough to beat. This power bank has a built-in rotating USB-C or Lightning connector (MFi certified), so you don’t need to worry about cables. It packs 5,000 mAh of energy (enough to fully charge most phones). I tested the USB-C version with several Android phones and found it stayed in place, enabling me to use my phone more or less as normal. There’s a USB-C port for recharging the power bank, and it comes with a short cable. It might not be a good pick if you use a thick case.

Ugreen

Amazon

Ugreen's charger is, as the name suggests, a 145-watt charger with a 25,000-mAh battery. It's surprisingly compact for the power it provides, although at 1.1 pounds, it's definitely not ultralight. There are two USB-C ports and one USB-A port. What sets the Ugreen apart is that you can actually draw 145 watts while charging. That works out to one USB-C port at 100 W and the other at 45 W. Very few other batteries we've tested are capable of that feat, and none that I know of at this size. If you want to charge fast, this is the power bank for you (although it's worth noting that reviews around the web suggest it doesn't support Samsung's fast-charging tech). There's a small LED readout on the side of the battery with the current charge state of the battery. I'd have liked to see some charging info on that screen as well, but that's a small quibble with what's an otherwise outstanding option if you need to keep your laptop charged up wherever you are.

GoalZero

Amazon

B&H

Goal Zero updated its Sherpa line of portable chargers with better wireless charging capabilities: 15 watts, up from 5 watts in the previous model. I tested the Sherpa AC, which features two USB-C ports (60-watt and 100-watt), two USB-A ports, and a 100-watt AC port for those devices that need a pronged plug. It strikes a good balance between power storage (93 watt-hours in my drain test) and weight (2 pounds). It’s enough to charge up my Dell XPS 13 almost twice.

You get a nice color LCD display that shows how much power you've got left, how many watts are coming in and how many are going out, and a rough guess as to how much longer the battery will last (if conditions remain the same). Recharge times vary depending on whether or not you have the Sherpa wall charger (sold separately), but I was able to get it to recharge in under three hours no matter what power source I used. There's also an 8-mm port on the back for attaching a solar panel if you have one. The Sherpa is not cheap, but if you don't need the AC out and can live with a single USB-C (100-watt out, 60-watt in), the Sherpa PD is otherwise the same thing for $175.

Anker

Amazon

Anker

My Apple Watch usually makes it to bedtime, but for super busy days and overnight trips, it’s nice to have a power bank capable of charging it up. This Anker power bank has a handy pop-up Apple Watch charger that can deliver 5 watts and supports Nightstand mode. It also has a built-in USB-C cable and a USB-C port, so you can deliver up to 30 watts to your phone or another small device. A display lights up beneath the surface to show you the remaining power as a percentage and the current charging rate. It’s nice and compact, with a generous 10,000 mAh capacity, and comes in black, white, green, or pink. Anker supplies stickers to stop your Apple Watch from sliding, but I didn’t find that to be a problem.

Sharge

Sharge

I am a sucker for Sharge’s transparent designs and cyberpunk aesthetic, but this prism-shaped power bank is more than just a pretty face. With a maximum output of 170 watts, a whopping 24,000-mAh capacity, and an IP66 rating for water resistance (fine in the rain, but best not to submerge), the Sharge 170 has form and function. The smart display shows battery life as a percentage, time remaining, and the input or output in watts. It supports many standards, including power delivery 3.1, Quick Charge 4.0, and PPS, and it fast-charged most of the devices I tested, including the iPhone 15 Pro, Pixel 8, Xiaomi 14 Ultra, and MacBook Air. You can simultaneously charge three devices at fast speeds, and the box includes a braided USB-C cable and a wee velvety bag. It can also recharge completely in an hour via USB-C at up to 140 watts (with the right cable and charger). The only thing I don’t like is the relatively high price. I also tested and loved an earlier release from this company, the Shargeek Storm 2 ($189), which has a larger capacity but tops out at 100 W.

Aohi

Amazon (40,000 mAh)

Long may this trend of sci-fi-styled portable chargers continue. The Aohi Starship looks like something you might find on the Nostromo, with a black and yellow design, three ports in one end, and a display to show remaining battery life as a percentage and wattage in and out. Information is in yellow, but the display is very dim (too dim to make out in direct sunlight). This power bank supports PD 3.1 and can deliver a chart-topping 240 watts for two devices via the two USB-C ports (140 watts and 100 watts), making it a good choice if you want to charge two laptops simultaneously.

You can fly with it in your carry-o and there's a 140-watt 3.3-foot USB-C cable in the box. Aohi also offers a smaller model that can deliver up to 210 watts via two USB-C ports or a bigger model capped at 140 watts.

Belkin

Amazon

Belkin

Sometimes, you simply want a cheap portable charger, and this sleek option from Belkin fits the bill. It is relatively slim for the 10,000 mAh capacity, with curved edges, and four LEDs to show remaining power. There are two USB-A ports and one USB-C port, and it comes with a short USB-A to USB-C cable. It can only deliver up to 15 watts in total, so it’s not the fastest power bank around, but that’s reflected in the low price, and it will get your gadgets charged eventually.

Gomi

Gomi

While I love the swirly designs, solid metal bottom, and compact size, it's Gomi’s ethos that sells these power banks. Handmade by a small indie business in Brighton, UK, from recycled plastic, with power generated by repurposed ebike batteries, Gomi claims at least 50 percent less CO2 emissions than comparable power banks. It looks and feels good, with curved sides, and Gomi promises up to 6-foot drop protection. A power button on the side lights up the four LEDs and shows how much of the 10,000-mAh capacity remains.

Both ports can deliver up to 18 watts, and you can charge two devices at once. It takes around four hours to fully charge from dead. There is a two-year warranty with this power bank, offering free repairs. Gomi has designed it to be easily repairable, so even out of warranty, you can get it fixed for a maximum cost of £20 ($25) plus shipping. If it should get damaged beyond repair somehow, Gomi will recycle it properly. You also get a braided USB-C to USB-C cable in the box.

Anker

Anker

The latest entry in Anker’s MagGo range is the first Qi2 power bank we've tested. The Qi2 wireless charging standard borrows elements of Apple’s MagSafe, enabling supported phones to connect with perfect alignment using a ring of magnets. Qi2 brings faster wireless charging rates of up to 15 watts, but it is also backward compatible, so older Qi devices can still charge, albeit more slowly. This compact portable charger has a handy kickstand, a two-way USB-C port on the left edge, and a power button with an LED display showing remaining power as a percentage of charge time on the right. It can accommodate Qi2 or MagSafe phones in portrait or landscape orientation (it works with Apple’s StandBy mode). I tested with an iPhone 14 Pro and got 25 percent in around 20 minutes. Despite a large capacity, it falls short of two full charges for your iPhone when charging wirelessly. You might squeeze out a little more if you plug in the short USB-C cable provided.

If you have an iPhone, we recommend some alternatives in our Best MagSafe Power Banks guide.

Displays in power banks are growing more common. All offer a precise readout of the remaining battery percentage, some show charging rates and other stats for power bank nerds, but this is the first one I’ve tried that has a cute wee robot face. This makes it easy to anthropomorphize (mine is named Charlie), but thankfully, it is also a super speedy power bank offering up to 100 watts, which is unusual in a charger this size. Light and easy to sling in a bag or even a pocket, Charlie can be fully charged in just 90 minutes and supports several fast charging protocols (PD, PPS, QC, AFC, FCP, and SCP). I also tried the 20,000 mAh model ($80), which ditches the face for a detailed stat readout on its color screen, but I prefer the smaller version.

Infinacore

Amazon

As a power bank, the P3 Pro is relatively big and expensive for its meager capacity, but it has a smart design that plugs directly into an outlet. Infinacore includes slide-on Type C, I, and G travel plug adapters, covering you for trips to the UK, Europe, and Australia, among other places. It has three ports, but you can turn it on its side to use the magnetic Qi2 wireless charging pad (up to 15 watts). It has a rubbery carry loop, and the soft touch finish ensures your gadgets won’t get scraped, though mine is already attracting dust and debris.

There’s a wee display showing remaining power, charging time, wattage in and out, and temperature, and it even changes orientation when you put the P3 Pro on its side on its rubber feet to use the wireless charging pad. Infinacore currently offers a gimmicky 99-year warranty, but you must register your device within 48 hours of buying.

BioLite

REI

Amazon

If you are hiking or camping, the BioLite is a handy companion. This durable power bank is versatile, a good size to slip into a bag, and has a nice grippy textured finish. The yellow plastic makes it easy to spot in a bag or crowded tent, and the segmented LED shows the remaining power in blocks of 10 percent. The Charge 100 Max can simultaneously charge up to five devices, and the wireless charging pad on top is handy in the dark when you don’t want to fumble with cables. If you don’t need such a large capacity, we also tested and liked Biolite’s smaller and simpler 6,000-mAh Charge 20 PD ($40), 10,000-mAh Charge 40 ($70), and 20,000-mAh Charge 80 ($100).

Elecom

Amazon (5,000 mAh)

Amazon (10,000 mAh)

Amazon (15,000 mAh)

Adventurers seeking a power bank that can survive camping in the rain or paddling down a river should check out the Nestout rugged power bank range from Elecom. These thoughtfully designed power banks boast an IP67 rating, have built-in shock absorbers, and are completely dustproof thanks to screw-on caps for the ports. Each power bank has a power button and five LEDs that show the remaining power in 20-percent increments.

The standard tripod threading on the bottom is super handy if you snag the dimmable lamp ($41) or light panel ($45) attachments. Both plug into the top of the power banks and are IP44-rated. There’s even a waterproof folding solar panel ($90) to keep the portable chargers topped up when you can’t get to an outlet.

Clutch

Amazon (USB-C)

Walmart (USB-C)

Target (Lightning)

The svelte Clutch Pro, available in black, white, or pink, is about the same size as a stack of credit cards and weighs around 4 ounces. It’s designed to slide easily into pockets and bags and offers a modest top-up for your phone’s flagging battery. The latest version of the super-slim portable charger is a little bigger but packs a larger battery than its predecessors, at 5,000 mAh. It can also stick to MagSafe iPhones magnetically. You charge it via the USB-C port, and there's a built-in charging cable (there's a different Lightning model). It’s slow, gets quite warm when plugged in, and a full Clutch added only around 40 percent to my iPhone 14 Pro’s battery. It also scuffs quite easily in a bag. You can get higher capacities and more efficient chargers for less, but portability is the point of the Clutch Pro, and it’s a handy size to tuck away in your bag for emergencies.

Ayaneo

Ayaneo

Most portable chargers are featureless plastic bricks, but Ayaneo proves power banks don’t have to be dull with this adorable retro replica of Nintendo’s Super Famicom, better known as the SNES (Super Nintendo Entertainment System) in the US. Super cute and lightweight at 238 grams, Ayaneo’s Retro Power Bank has a tiny OLED showing the remaining battery, charging speed, protocol, and temperature. The function button brings it to life, and the slide switch cycles through the display options. It can send or receive up to 45 watts, but that’s a total for the output, so if you charge two devices simultaneously, you’ll get 15 W and 30 W. It supports PD 3.0, QC 3.0, and SCP. It’s a handy size, works reliably, and always catches the eye of older gamers.

Bluetti

Amazon

Bluetti

The more power you pack into a portable charger, the less portable it becomes. Bluetti’s solution is a custom-designed 42-liter backpack with a slim 268.8-WH solar generator that slides into a slot in the back. There are plenty of ports to keep your gadgets topped off; there’s even an AC socket and enough power for a couple of days of hiking. If you pair solar panels, you can go off-grid indefinitely. The pack is bulky and weighs 11 pounds (5 kg) before you load your stuff in (it can bear up to 66 pounds or 30 kg). The designers took an everything-but-the-kitchen-sink approach, so it has adjustable velcro foam dividers, Molle straps, and zippered pockets galore. It’s ideal for trips with photography gear or drones. The two side panels zip open to enable you to access the ports easily, and there’s an LED display to show remaining power and watts in and out, though it can be tough to read in direct sunlight.

The Bluetti Handsfree 1 comes with a 4.9-foot AC charging cable and a 4.9-foot MC4-XT60 solar charging cable. It took me over an hour and a half to fully charge from an outlet. If you go for the optional 60-watt solar panel array, it will take around six hours, depending on the weather. But the cool thing about that is you can unfurl and attach the solar panels to hang down your back and charge while you hike. On the downside, I had to lean forward with this fully loaded, and it’s only splash-proof, though Bluetti includes a rain cover. If you need more power, the 60-liter Bluetti Handsfree 2 ($599) has a 512-WH battery.

Anker

Amazon

Anker

There is plenty to like about Anker’s Solix C300 DC. This portable charger has a whopping 90,000 mAh capacity, so it can easily keep your gadgets topped off for a weekend in the wilderness. It has a lovely pop-up lantern with three brightness settings and a versatile array of ports. You can charge it to 80 percent in an hour using the two fast USB-C ports, but it also has an XT60 input for a 100 W solar panel (it took me several hours to fully charge this way) and a socket for charging from your car. It is heavy at 6.17 pounds, but the tall form and carry handle make it easy to take with you, and Anker sells an optional shoulder strap for $30. You can connect the Anker app on your phone via Bluetooth or Wi-Fi, but you don’t need to, as the display shows the percentage remaining, watts in or out, and a remaining time estimate. If you are hiking with a pack to go camping, this is the highest capacity portable charger you can realistically carry easily.

Jackery

Amazon

Best Buy

REI

Folks seeking more power for camping or a long road trip should pick up the Jackery Explorer 300 Plus. This cute and compact battery has a fold-out handle, packs a 288-WH capacity, and weighs 8.3 pounds. It has two USB-C ports (18 W and 100 W), one USB-A (15 W), a car port (120 W), and an AC outlet (300 W, 600 W surge). There is plenty of power to keep your small gadgets going for a few days. There’s also an AC input, or you can charge it via USB-C. The fan kicks in sometimes, but the Silent Charging Mode keeps it below 45 decibels. You can manage it with Jackery’s app via Bluetooth, and it also has a handy flashlight. We have found Jackery gear reliable and durable, and you can expect to get at least a decade out of this battery. Go any bigger than this and portability gets debatable. We have a separate Best Portable Power Stations guide with recommendations for anyone who needs a lot of power.

If you want charging options for going off-grid, you can get the 300 Plus with a 40-W book-sized solar panel ($400). It took me around eight hours to charge the battery with this panel in blue sky sunshine. If you want a faster charge and have the space for a larger panel, consider the 300 Plus with 100-W solar panels ($500).

Noco

Amazon

Walmart

It’s a horrible feeling when your car refuses to start because the battery is dead, but if you have a portable battery pack like this one in your trunk, you can give yourself a jump-start. Former WIRED reviewer Eric Ravenscraft called it a roadside lifesaver after it jump-started his car several times on a long trip home from out of state. The Noco Boost Plus is a 1,000-amp, 12-volt battery pack with jump leads. It also has a USB-A port to charge your phone and a built-in 100-lumen LED flashlight. It’s a good thing to have in your trunk, but you must remember to charge it every six months. It’s also IP65-rated and good for temperatures from –4 degrees Fahrenheit up to 122 degrees.

Panasonic

Amazon (AA x 4)

Amazon (AAA x 4)

Amazon (Standard Charger)

Amazon (Fast Charger)

Got devices that don't charge via USB? Yes, they're still around. I have an old, but still great, GPS device that runs on AA batteries, headlamps that take AAA batteries, and countless other odds and ends that need batteries. After running through several brands, I've found Eneloop rechargeable batteries to be the longest-lasting and most reliable. The fast Panasonic charger can recharge any combination of AA and AAA batteries in less than four hours, and you can sometimes get it bundled in a pack that includes four AA Eneloop rechargeable batteries.

The standard AA Eneloop batteries hold around 2,000 mAh each, with AAA batteries holding 800 mAh, but you can upgrade to Eneloop Pro (2,500 mAh and 930 mAh, respectively) for more demanding gadgets, or go for Eneloop Lite (950 mAh and 550 mAh) for low-power devices. They come precharged with solar energy, and Eneloop recently switched to plastic-free cardboard packaging.

Rechargeable batteries are a smart idea, and Eneloop are the best, but if you need alkaline batteries for some reason and you are in Europe, check out the Itson range. They are made in the EU from recycled materials and are very affordable.

There are so many portable chargers out there. Here are a few more we like that just missed out on a place above for one reason or another.

OnePlus Slim Magnetic Power Bank for $70: Sleek in silver grey aluminum with a chamfered edge, this power bank looks lovely and is very slim, measuring 3.77 x 2.71 x 0.34 inches, not to mention lightweight at just 120 grams. But the 5,000-mAh capacity is just over half that after inefficiency takes a bite. Wireless charging tops out at 10 watts for Android and 7.5 watts for iPhone (even wired charging is limited to 10 watts). You can snag better performers for less.

Denvix PowerX Power Bank for $180: This beefy 25,000 mAh power bank can put out up to 200 watts via two USB-C ports, one USB-A, and a Qi wireless charging pad, to charge four devices simultaneously, maybe a laptop, a couple of phones, and some earbuds. The display shows power remaining, watts in or out, temperature, and a few other stats. It’s a solid option if you want something that can charge laptops, but the finish is a little too smooth, and it gets very warm when charging multiple devices.

Sharge Flow Mini for $19: With a similar design to Anker’s Nano Power Bank above and the same 5,000-mAh capacity, you might be tempted to go for this instead. It comes with interchangeable USB-C to USB-C or Lightning connectors (which I worry will be easy to lose) and has a built-in USB-C cable that doubles as a strap, though it’s tricky to pull out. There’s a power button with four LEDs to show the remaining power, and it only takes an hour and a half to refill, but the charging rate maxes out at 12 watts either way.

Cuktech 10 Power Bank for $40: With impressive build quality, including a nice grippy material on the underside and a handy display showing power output and input, this Cuktech (pronounced chook-tek) power bank almost earned a place above. Despite the modest capacity, it is built for speed and capable of outputting 100 watts, with support for PD 3.0 and PPS. It can also recharge in less than an hour (up to 90 W). The trade-off for the high speed is low efficiency. You won’t get anywhere near the 10,000-mAh capacity advertised, but this is true of most power banks. I also tested the higher-capacity Cuktech 15 Ultra ($120), which boasts double the power, can charge two or three devices simultaneously at up to 165 watts, and supports many fast-charging protocols including PPS, QC, PD3.1, FCP, SCP, and MiPPS.

Baseus Blade 2 for $70: With an extremely thin design, this 12,000-mAh-capacity power bank is easy to slip into a backpack and can charge most phones a couple of times or top up a laptop at up to 65 watts. It has a display showing battery life as a percentage of time remaining and the input or output for both USB-C ports. We've tried many products from up and down the Baseus product line. While they are generally reliable, we do think there are better options.

Rugd Power Brick for $50: This shock- and water-resistant (IP67 certified) charger doubles as a bright 16-LED with an SOS mode, and has a hefty 10,050-mAh capacity (one USB-C at 18 W and a USB-A that supports QC). It’s also bright orange, weighs just 280 grams, and comes with a carabiner for easy attachment, all of which make it an excellent camping buddy.

FansDreams MChaos for $46: I love the idea of a wearable power bank, and this one comes in lime green with a carabiner that makes it easy to attach to a bag. It also has a built-in, retractable, 28-inch USB-C cable to charge your phone at up to 20 watts. Recharging the power bank is a little slower at 18 watts. The colored LED gives you a sense of remaining juice as it goes from green to orange to red, but the 5,000-mAh capacity means you’ll be lucky to get one full charge for your phone, and even the discounted price feels a little high. I also tested the 10,000-mAh model ($50), which has a nicer design. Pull the 2.3-foot retractable USB-C cable out and the percentage remaining pops up visible through the shiny plastic of the case. There’s a USB-C port on the bottom for charging, and it goes up to 22.5 watts either way.

Infinacore Pandora Portable Power Global Wireless Charger for $50: This was our pick for the best wall-charger power bank, and it is still a decent charger that plugs directly into the wall. It has the advantage of optional EU and UK plug adapters for an extra $10, making it a handy travel companion. It offers 8,000 mAh via one USB-C port, two USB-A ports (18 W total), and Qi wireless charging (5 W).

Iniu Power Bank BaI-B64 for $72: Offering relatively low prices, Iniu is a power bank brand on the rise. This portable charger packs a 27,000-mAh capacity, can put out up to 140 W, and charges three devices at once via two USB-C ports and a single USB-A port. We also tested the very similar BI-B63 ($60), which has a slightly lower capacity at 25,000 mAh but seems like a better value. Unfortunately, both fell slightly short of the stated capacity when tested. We also like the color options available in the company's slimmest version.

Anker Prime Power Bank for $130: With a total combined output of 200 W and a hefty 20,000-mAh capacity, this is a solid choice for charging any device; you could even use it to charge two laptops at once via the two USB-C ports. There is a USB-A port, too, and a digital screen. You can also buy a Power Base ($110) for this, which enables you to stick the power bank on top and charge it via Pogo Pins. The base makes it easy to keep the power bank topped up and is handy for desktop charging with two USB-C ports and one USB-A port (combined max output 100 W). I tried the UK version (£130), which worked great, but WIRED reviews editor Julian Chokkattu had issues with the US base failing to charge the power bank.

Anker Nano Power Bank 10,000 for $40: Another solid option from Anker (also available for £30 from Amazon UK), this power bank has a built-in USB-C cable that doubles as a loop for easy carrying and a further one USB-C and one USB-A port. It has a 10,000-mAh capacity, good for just shy of two full charges for most phones. It maxes out at 30 watts each way and can be fully charged in around two hours.

Mpowered Luci Pro Lux for $50: This solar-powered inflatable lantern boasts 10 LEDs and emits a lovely warm glow that’s perfect for camping or walking at night. It is IP67-rated and packs down flat for easy carrying. While it’s not primarily a power bank, the 2,000-mAh battery in the Luci Pro can charge your phone in an emergency. A nearly full Luci Pro boosted my Pixel 6 Pro by around 25 percent. It takes at least 14 hours to charge back up using the solar panels, or you can plug into an outlet and recharge in three.

Mophie Powerstation, Powerstation XL, and Powerstation Pro AC for $28+: Mophie's 2023 update to its Powerstation line has three devices in 10,000-, 20,000-, and 27,000-mAh capacities. They're bulky, nondescript devices with USB-C and USB-A ports, but the latter has an AC port and is great for travel. WIRED reviews editor Julian Chokkattu used the XL during his trip to Japan and had no trouble keeping his Switch Lite and Pixel 7 Pro topped up. There are LEDs to indicate remaining battery life, but there's otherwise nothing special about 'em.

iWalk Portable Charger for $22: WIRED reviews editor Julian Chokkattu used the Lightning version of this power bank while covering the Apple event and it reliably topped up his iPhone. The 4,800-mAh capacity won't fully refill your device, but it's tiny enough to keep in a bag at all times. There's an LED that shows the remaining percentage of power left. The company also has a MagSafe power bank ($27).
