The best power banks for 2023

The best power banks for 2023

Whether you call them battery packs, power banks or portable chargers, these accessories do one thing well: charge devices when you can’t find an open outlet. Whether you’re heading out for a long work day or a long weekend to visit family and friends, battery packs are small, sturdy and powerful enough to charge your smartphone, tablet, laptop or even all three at once, depending on their size. Take stock of the devices you need when you’re on the go — those will dictate the size and type of power bank you’ll want to buy. With so many options on the market right now, we tested out a bunch of models to determine the best portable power banks you can get right now.
<h2>What to look for in a portable battery pack</h2>
<h3>Battery type</h3>
Nearly every rechargeable power bank you can buy (and most portable devices) contain a lithium-ion battery. These beat other current battery types in terms of size-to-charge capacity, and have even <a data-i13n="cpos:1;pos:1" href="https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries">increased[/url] in energy density by eight fold in the past 14 years. They also don’t <a data-i13n="cpos:2;pos:1" href="https://www.cei.washington.edu/education/science-of-solar/battery-technology/">suffer[/url] from a memory effect (where battery life deteriorates due to partial charges).
One drawback you may have heard is the possibility of lithium ion batteries <a data-i13n="cpos:3;pos:1" href="https://www.engadget.com/lithium-ion-battery-salt-fireproofing-213055538.html">catching fire[/url]. To limit the danger, battery packs require internal mechanisms to limit things like voltage and pressure. While you should still make sure a battery isn’t exposed to unnecessary stress like excessive heat, damage from drops or operating in freezing weather, battery packs are considered safe enough to bring on an airplane. According to the <a data-i13n="cpos:4;pos:1" href="https://www.tsa.gov/travel/security-screening/whatcanibring/items/lithium-batteries-100-watt-hours-or-less-device">TSA[/url], external batteries rated at 100Wh or less (which all of our recommendations are) can fly with you – just make sure you stash them in your carryon the next time you fly as they aren’t allowed in checked baggage.
<h3>Capacity</h3>
Power bank manufacturers almost always list a battery’s capacity in milliamp hours, or mAh. Smaller batteries, say those that can charge a smartphone to between 50 and 75 percent, tend to have a 5,000mAh capacity. Larger batteries that can recharge laptops and tablets, or give phones multiple charges, can exceed 25,000mAh. Unsurprisingly, the prices on most batteries goes up as capacity increases, and since batteries are physical storage units, size and weight go up with capacity as well. If you want more power, be prepared to spend more and carry around a heavier brick.
You might think that a 10,000mAh power bank could charge a 5,000mAh phone to 100 percent twice, but that’s not the case. In addition to simple energy loss through heat dissipation, factors like voltage conversion also bring down the amount of juice that makes it into your phone. Most manufacturers list how many charges a battery can give a certain smartphone. In our tests, 10,000mAh of battery pack capacity translated to roughly 5,800mAh of device charge. 20,000mAh chargers delivered around 11,250mAh to a device, and 25,000mAh banks translated to about 16,200mAh of charge. That’s an average efficiency rate of around 60 percent.
<h3>Ports</h3>
While the tech world is (thankfully) moving towards USB-C charging as the <a data-i13n="cpos:5;pos:1" href="https://www.engadget.com/eu-usb-c-port-charging-requirement-approved-141546579.html">standard[/url], it’s still a mixed bag in the power bank world. All of our picks have at least one USB-C port and a few also have a USB-A port or two. Newer Android smartphones charge via USB-C, iPhones <a data-i13n="cpos:6;pos:1" href="https://www.engadget.com/apple-airpods-mac-accessories-usb-c-report-170406614.html">still use the[/url] Lightning port, but the latest tablets (including current generation iPads) and newer laptops are typically powered up via USB-C.
When a battery pack has more than one charging port, they usually serve different functions. You’ll typically see at least one port labeled “in/out,” which means you can use it to both charge the bank and charge your device. While USB-A ports can power up smartphones and other small devices, they can’t charge larger devices. Plus, they aren’t as fast as USB-C ports overall. That’s something to keep in mind when you’re deciding which ports and charging cables to use to connect your phone to the pack.
There’s even more variation among USB-C ports themselves, with different ports on the same device supporting different power transfer rates. What that means in practical terms is an iPhone will charge just fine plugged into a power bank’s 18W port. But to properly charge, say, a MacBook or similar laptop, it’ll need the extra juice supplied by a 100W port (which larger power banks can offer). Power banks with more than one port can also charge multiple devices at the same time, but speeds and the overall charge delivered will be lower.
You’ll also want to consider your charging cable. For anything larger than a smartphone (and to access fast-charging capabilities) you’ll want to use USB-C ports and cables. But not all cables are created equal, even when they have the same USB-C plugs on the end. If you want power delivery from a 100W USB-C power bank port, you’ll need a 100W-rated USB-C cable. Luckily, power banks capable of delivering 100W tend to include a compatible cable. For any devices that don’t, we’ve tried and liked <a data-i13n="cpos:7;pos:1;elm:affiliate_link;sellerN:Amazon;elmt:" href="https://shopping.yahoo.com/rdlw?merchantId=66ea567a-c987-4c2e-a2ff-02904efde6ea&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=Amazon&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsInN0b3JlSWQiOiI2NmVhNTY3YS1jOTg3LTRjMmUtYTJmZi0wMjkwNGVmZGU2ZWEiLCJsYW5kaW5nVXJsIjoiaHR0cHM6Ly93d3cuYW1hem9uLmNvbS9ncC9wcm9kdWN0L0IwOFBWUUM1QzYvP3RoPTEmdGFnPWdkZ3QwYy1wLW8taXItMjAiLCJjb250ZW50VXVpZCI6IjExNDlkMThhLTM2NmQtNDFlNy05Y2ZhLTdjZTRkMGZkNjgzNSJ9&signature=AQAAAR_xsREa_And-v6ZXl_ejxtt2D4oWXYQ-2zL5SSYmK0M&gcReferrer=https%3A%2F%2Fwww.amazon.com%2Fgp%2Fproduct%2FB08PVQC5C6%2F%3Fth%3D1">Anker’s 100W USB-C cable[/url].

For around $20, higher-capacity charging cables will make sure you’re not wasting time with connections that limit your potential power transfer.
<h3>Design</h3>
For the most part, battery packs have a squared-off, brick-like design, though many nod towards aesthetics with attractive finishes and detailing. While that doesn’t affect how they perform, it’s a consideration for something you’ll interact with regularly. Some portable power stations include extra features like MagSafe compatibility, a built-in wall plug or even a kickstand. Nearly all have some sort of indicator to let you know how much available charge your power bank has left, usually expressed with lighted pips near the power button. Some of the largest banks take that a step further with an LED display indicating a percentage for the remaining battery, which can be helpful if you’re relying on a pack in a mobile office setting or something similar.

I used the charging cable included with each power bank to charge the Galaxy S22 Ultra, MacBook Pro and the iPad Air. For the iPhones, I used the USB-C to Lighting cable that Apple provides. In the case of the lower-capacity power banks that didn’t include a cord or included one with USB-C to USB-A connectors, I used this <a data-i13n="elm:affiliate_link;sellerN:nimble;elmt:;cpos:26;pos:1" href="https://shopping.yahoo.com/rdlw?merchantId=88872e72-f0df-4301-b936-bf22f074034c&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=nimble&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsImxhbmRpbmdVcmwiOiJodHRwczovL3d3dy5nb25pbWJsZS5jb20vY29sbGVjdGlvbnMvdXNiLWMtY2FibGVzL3Byb2R1Y3RzL3VzYi1jLWNhYmxlLXBvd2Vya25pdCIsImNvbnRlbnRVdWlkIjoiMTE0OWQxOGEtMzY2ZC00MWU3LTljZmEtN2NlNGQwZmQ2ODM1In0&signature=AQAAAWJmFK5yLOrU_OxXHu5r_FfdjuwPrTE0Drz9ZoHY5j4C&gcReferrer=https%3A%2F%2Fwww.gonimble.com%2Fcollections%2Fusb-c-cables%2Fproducts%2Fusb-c-cable-powerknit" class="rapid-with-clickid" data-original-link="https://www.gonimble.com/collections/usb-c-cables/products/usb-c-cable-powerknit">60W-rated USB-C to USB-C cable[/url].

The ArcHybrid firmly attaches to the MagSafe ring and it’s flush enough that you can easily hold your phone and use it while charging up. Unlike the Apple battery, it includes four indicator lights to help you gauge how much juice the pack itself has left. Considering Spigen’s battery is $30 cheaper than Apple’s, it’s easy to recommend.
Alternatively, <a data-i13n="cpos:31;pos:1;elm:affiliate_link;sellerN:Amazon;elmt:" href="https://shopping.yahoo.com/rdlw?merchantId=66ea567a-c987-4c2e-a2ff-02904efde6ea&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=Amazon&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsInN0b3JlSWQiOiI2NmVhNTY3YS1jOTg3LTRjMmUtYTJmZi0wMjkwNGVmZGU2ZWEiLCJsYW5kaW5nVXJsIjoiaHR0cHM6Ly93d3cuYW1hem9uLmNvbS9ncC9wcm9kdWN0L0IwOU5SRzRHSzM_dGFnPWdkZ3QwYy1wLW8taXItMjAiLCJjb250ZW50VXVpZCI6IjExNDlkMThhLTM2NmQtNDFlNy05Y2ZhLTdjZTRkMGZkNjgzNSJ9&signature=AQAAAWuPZ_3RYcYEmx3XFQgziyupe0FJjwyWL4AmrRy1usQD&gcReferrer=https%3A%2F%2Fwww.amazon.com%2Fgp%2Fproduct%2FB09NRG4GK3">Anker’s 633 Magnetic[/url] battery delivered a larger charge thanks to its 10,000mAh capacity, boosting the iPhone to 100 percent in three hours with enough left over for an additional 29 percent charge. And while the kickstand feature felt mildly useful, the battery itself was bulky – but that’s understandable for a power bank that’s twice as large as Spigen’s. Ultimately, the ArcHybrid performed better as a quick and convenient way to give a partial charge to your iPhone on the go.
It’s important to note that wireless charging is less efficient than wired. Our tests showed wired battery banks deliver a device charge at around 60 percent efficiency. With the wireless chargers, that rate dropped to an average of 46 percent. Something to keep in mind when weighing the costs, both ecological and monetary, of wasted energy.

The battery has enough capacity to charge a depleted Galaxy S22 Ultra to 75 percent in a little over an hour, so you’ll be covered if you don’t have long between flights to give your phone a bit more juice. It also has a built-in plug and allows for pass-through charging, which means it can act as a wall adapter if you’re ever stuck with both a dead battery bank and phone, but happen to be near an outlet. It doesn’t come with a cable, though, so you’ll need to provide one that can go from the bank’s single USB-C port to your device.

<core-commerce id="9fb13ec7369243b1bb2a076773c71914" data-type="product-list"></core-commerce>
BioLite is probably better known in the outdoor community than the tech world, and it’s fair to say that the <a data-i13n="cpos:34;pos:1;elm:affiliate_link;sellerN:BioLite;elmt:" href="https://shopping.yahoo.com/rdlw?merchantId=c7108adf-28cd-4cee-8929-a1014adc3d98&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=BioLite&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsInN0b3JlSWQiOiJjNzEwOGFkZi0yOGNkLTRjZWUtODkyOS1hMTAxNGFkYzNkOTgiLCJsYW5kaW5nVXJsIjoiaHR0cHM6Ly93d3cuYmlvbGl0ZWVuZXJneS5jb20vcHJvZHVjdHMvY2hhcmdlLTQwLVBEIiwiY29udGVudFV1aWQiOiIxMTQ5ZDE4YS0zNjZkLTQxZTctOWNmYS03Y2U0ZDBmZDY4MzUifQ&signature=AQAAASr_WKmfS5i4ZbGXbyABmsC4zYdjdQOP5QM6d1hBdp7a&gcReferrer=https%3A%2F%2Fwww.bioliteenergy.com%2Fproducts%2Fcharge-40-PD">Charge 40 PD[/url] is geared more towards camping trips than urban commutes. But this battery simply outperformed the others in its category. The rugged, yellow-accented exterior is a refreshing change from the standard shiny black of many tech accessories. It also has a rubberized finish and feels solid enough to handle the bumps and jolts of riding around in a purse or messenger bag all day. It gave both the iPhone and the Galaxy one and a half charges, which means it’s plenty capable of reviving a dead phone a couple of times when you’re out and about.
The <a data-i13n="cpos:35;pos:1;elm:affiliate_link;sellerN:;elmt:" href="https://shopping.yahoo.com/rdlw?siteId=us-engadget&pageId=1p-autolink&featureId=text-link&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsImxhbmRpbmdVcmwiOiJodHRwczovL3d3dy5nb25pbWJsZS5jb20vY29sbGVjdGlvbnMvcG9ydGFibGUtYmF0dGVyeS1jaGFyZ2Vycy9wcm9kdWN0cy9jaGFtcC1wb3J0YWJsZS1jaGFyZ2VyIiwiY29udGVudFV1aWQiOiIxMTQ5ZDE4YS0zNjZkLTQxZTctOWNmYS03Y2U0ZDBmZDY4MzUifQ&signature=AQAAAd6EcGyu1V9q1xaUOKOdyi6jJKW4FoemqVdb-iB1Q3x9&gcReferrer=https%3A%2F%2Fwww.gonimble.com%2Fcollections%2Fportable-battery-chargers%2Fproducts%2Fchamp-portable-charger">Nimble Champ[/url] gets an honorary mention here because it’ll also deliver a few reliable fill-ups and comes in a rugged package. It delivered a full charge to the iPhone in two hours plus a 22 percent charge in 16 minutes. It gave the Galaxy a full charge in an hour and 44 minutes, then got the phone from dead to 41 percent in 50 minutes. At the same $60 price point as the BioLite, Nimble gets extra points for being one of the few <a data-i13n="cpos:36;pos:1" href="https://www.bcorporation.net/en-us/find-a-b-corp/company/nimble">B-Corp-certified[/url] personal tech manufacturers out there, meaning they’ve committed themselves to higher environmental and social standards, and took the time to prove it through B Lab’s certification process.
<h2>Best medium capacity battery: Otterbox Fast Charge</h2>

Over the month and a half I spent testing battery packs, this was the unit I grabbed the most when my own devices needed a charge. It has a stylish exterior with a gray faux leather finish and copper detailing. A little bigger than a deck of cards and weighing just over 11 ounces, it’s a nice looking accessory that feels solid.
It filled up both smartphones twice, then gave an additional third of a charge each. I introduced the iPad to the mix here and got a full charge plus an extra third. The Otterbox also lost very little battery power while sitting dormant, which means if you carry it around on the off chance that you’ll need it, it should have plenty of power when the time comes.

The 737 fully charged our S22 Ultra three times, with enough power left over for another 93 percent charge – and those full charges completed in under an hour on average. That’s on par with wall charging. The numbers for the iPhone were slightly less staggering, but still impressive, going from zero to full in about an hour and a half. The iPad charged completely twice, and did so in just over two hours, which is also close to that device’s wall-connected charge speeds.
While it’s great for multiple full charges on a given smartphone, I should point out that the 737 has three ports, but only one of those provides USB-C charging. If you want to charge more than one device at a time, you’ll have to use the lower-efficiency USB-A ports for a couple of them.

The TSA’s 100-watt-hour battery limit translates to around 27,000mAh for lithium ion batteries. <a data-i13n="elm:affiliate_link;sellerN:Amazon;elmt:;cpos:46;pos:1" href="https://shopping.yahoo.com/rdlw?merchantId=66ea567a-c987-4c2e-a2ff-02904efde6ea&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=Amazon&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsImxhbmRpbmdVcmwiOiJodHRwczovL3d3dy5hbWF6b24uY29tL21vcGhpZS1wb3dlcnN0YXRpb24tcHJvLWNvbXBhdGJpbGUtaW50ZWdyYXRlZC9kcC9CMEJXU0RXWjk2P3RhZz1nZGd0MGMtcC1vLWlyLTIwIiwiY29udGVudFV1aWQiOiIxMTQ5ZDE4YS0zNjZkLTQxZTctOWNmYS03Y2U0ZDBmZDY4MzUifQ&signature=AQAAAZ3IdN1oJeLobQrU1UhPsBK-2Q9qVMSI8Ux4RIeU6UDP&gcReferrer=https%3A%2F%2Fwww.amazon.com%2Fmophie-powerstation-pro-compatbile-integrated%2Fdp%2FB0BWSDWZ96" class="rapid-with-clickid" data-original-link="https://www.amazon.com/mophie-powerstation-pro-compatbile-integrated/dp/B0BWSDWZ96">Mophie’s Powerstation Pro AC[/url] is so massive it necessitates a grab handle and get close to the edge of that max carry-on size. You probably won’t find a larger, acceptable portable power bank — after all, an on-the-go charging brick is pointless if you can’t travel with it. I took this one through security at two airports and no one gave it a second glance.
To power your mobile work setup, the Powerstation has four ports. Three of them are the usual USBs, but there’s also a three-prong AC outlet. Most current devices charge via USB (and doing so is more efficient than using a power adapter between the cable and power bank), but older devices and certain mobile workstation accessories — speakers, lights and printers come to mind — might only power up through a basic wall plug. Just be sure to hold down the status button until the light turns red to turn on the AC port.
The AC plug powered most small appliances I plugged into it, including a small speaker, an HP printer and various LED lights. The 100 available watts isn’t enough to continuously push a charge through the 140W power adapter that ships with the 16-inch MacBook Pro, but via the USB-C port, it was able to charge that laptop from 10 percent to 75 percent in under 90 minutes.
The four lighted LED indicators will tell you when the battery is full. Unfortunately, it’s not the best indicator of when the bank will run out of juice. It charges for quite a while with four and three pips lit up, but then quickly cycles through the last two dots before it dies. So it might be better to just remember how much you’ve used the brick rather than relying too heavily on its indicators.
Smaller devices like a smartphone will get numerous charges; I got nearly five refills on an iPhone 11, and two charges and some change on an iPad. The Powerstation Pro AC was even a little faster at both tasks than our <a data-i13n="elm:affiliate_link;sellerN:Zagg;elmt:;cpos:47;pos:1" href="https://shopping.yahoo.com/rdlw?merchantId=6391fb09-49b1-4860-b92a-12edb53cb14e&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=Zagg&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsImxhbmRpbmdVcmwiOiJodHRwczovL3d3dy56YWdnLmNvbS9wb3dlcnN0YXRpb24tcHJvLXhsLWFwcGxlP3NrdT00MDExMDk1NjUiLCJjb250ZW50VXVpZCI6IjExNDlkMThhLTM2NmQtNDFlNy05Y2ZhLTdjZTRkMGZkNjgzNSJ9&signature=AQAAAaXbQin-wdrCnvqvg8dTtTY2Pl0y8W_DcyD6_tAER4f_&gcReferrer=https%3A%2F%2Fwww.zagg.com%2Fpowerstation-pro-xl-apple%3Fsku%3D401109565" class="rapid-with-clickid" data-original-link="https://www.zagg.com/powerstation-pro-xl-apple?sku=401109565">previous pick[/url] for a mobile command center.

Magnets help align the pins so you can just plonk the battery down and move on with your life. The set will run you $200, which is pretty spendy for a battery bank, but if you consider that the base offers extra ports (one USB-A and two USB-C), you can also use it as a power hub for other devices, which takes some of the sting out of the price.
The battery itself has the same three ports and a blocky, upright design. The case is a textured metallic plastic with a high-polish, built-in screen and rounded corners. It tells you how many watts are flowing out to each device and displays the overall remaining charge within the battery. When you press the power button, it takes a moment to wake. But the extra processes that run the screen don’t seem to slow the battery down or diminish the power it has to give. Its charge times and capacity was on par with the other 20K batteries I’ve tested.
I’ve been pretty careful with my review unit, but I’d be worried that the sleek and shiny finish will get wrecked with regular use. It does come with a faux-suede pouch to carry it in, but I doubt anyone will use that regularly — after all, the whole appeal of the Prime’s base and battery set is the low-hassle efficiency.

<core-commerce id="0f8ed1a272674082a5231ee515e10569" data-type="product-list"></core-commerce>
Plenty of battery packs are built to withstand drops and other abuse, but very few are waterproof or even water resistance. It makes sense; water and electrical charges aren’t good companions. The <a data-i13n="elm:affiliate_link;sellerN:Amazon;elmt:;cpos:50;pos:1" href="https://shopping.yahoo.com/rdlw?merchantId=66ea567a-c987-4c2e-a2ff-02904efde6ea&siteId=us-engadget&pageId=1p-autolink&featureId=text-link&merchantName=Amazon&custData=eyJzb3VyY2VOYW1lIjoiV2ViLURlc2t0b3AtVmVyaXpvbiIsImxhbmRpbmdVcmwiOiJodHRwczovL3d3dy5hbWF6b24uY29tL0VMRUNPTS1Qb3J0YWJsZS0xNTAwMG1BaC1XYXRlcnByb29mLVNob2NrcHJvb2YvZHAvQjBCWDM2OFlYRz90YWc9Z2RndDBjLXAtby1pci0yMCIsImNvbnRlbnRVdWlkIjoiMTE0OWQxOGEtMzY2ZC00MWU3LTljZmEtN2NlNGQwZmQ2ODM1In0&signature=AQAAAW3jxrFnUq8alN7zvnORHTiMd8ii7SShLwTLR5aAcmMm&gcReferrer=https%3A%2F%2Fwww.amazon.com%2FELECOM-Portable-15000mAh-Waterproof-Shockproof%2Fdp%2FB0BX368YXG" class="rapid-with-clickid" data-original-link="https://www.amazon.com/ELECOM-Portable-15000mAh-Waterproof-Shockproof/dp/B0BX368YXG?th=1">Nestout Portable Charger[/url] battery has an IP67 rating, which means it can handle being submerged in water for a number of minutes, and Nestout claims a 30-minute dunk in a meter of water shouldn’t interfere with the battery’s operation. I couldn’t think of a likely scenario where a power bank would spend a half hour in three feet of water, but I could see a backpacker traversing a river and submerging their pack for a few minutes, or a sudden downpour drenching all of their gear. So I tested by dropping the battery in a five gallon bucket of water for five minutes. After drying it off, the unit performed as if it had never been wet.
The water resistance comes courtesy of screw-on caps with silicone gaskets that physically keep the water out, so you’ll need to make sure you tighten (but don’t over tighten) the caps whenever you think wetness is in your future. The company also claims the battery lives up to a military-standard shock/drop specification which sounds impressive, but it’s hard to pin down what exactly that means. I figured it should at minimum survive repeated drops from chest height onto a hard surface, and it did.
As for charging speeds, it wasn’t quite as quick as our recommendation for a mid-capacity bank. The Otterbox charged an iPhone 14 Plus to 80 percent in about an hour and the Nestout got the smaller iPhone 11 to 80 percent in the same amount of time. Another thing to note is that the supplied cable is short, just seven inches total, so you’ll likely want to use your own cord.
