About this deal

We'd recommend avoiding anything below 5,000mAh, though, as they'll barely recharge today's smartphones. Look for between 5,000 and 10,000mAh. Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery.

All of our tests were conducted using the same wall adapter and, when possible, USB-C or Micro-USB cable. This was done to eliminate any discrepancies with wall adapters and cable throughput. What to look for in a portable power bank Power Delivery is a newer protocol in which two compatible devices negotiate on the fastest charging option available based on the charger, cable, and circuitry. It also allows for power to flow both ways.

Most power banks now use a USB-C port to recharge, although some models will have a micro-USB port as well to ensure compatibility with older chargers. Don’t worry if you don’t have the required cable, as one will usually be provided in the box. To further complicate matters, some energy is also lost through heat. The energy lost can be as low as 15% with some models, but can be much higher in others. Just like the Sanag portable charger, Q’s offering is a charger and a power bank combined into one unit. However, there are some differences in the design and functionality. To wit, the Q power bank is slimmer and despite that, it offers a similarly capacious cell to top up your devices and accessories. You want a more portable option: Because of its combo nature, the Anker 733 is a bit bulky and cumbersome, but if you use it both ways, it's worth the trade-off in size to have such a useful device.

To calculate the mAh you’ll actually get when charging devices, multiply the claimed capacity by 3.7 then divide that figure by five (or whatever voltage you’ll be charging at).

The World's No. 1 Mobile Charging Brand*

Brand Reliability: When it comes to portable power banks, it's essential to choose a trustworthy brand. Brands like Anker have a solid reputation for producing safe and high-quality products, ensuring your devices are charged efficiently and without any risks.

That app is essential because there's a Find My feature built into the battery. It doesn't work like an AirTag over UWB, it's only Bluetooth, but it's useful if you misplace your battery in your office (or you have multiple batteries, like I do).

The best power banks you can buy in 2023

If you have a newer Android phone, or the latest iPhone 15 models, you'll want a power bank with faster charging speeds to get your battery full faster. Charging speed is measured in wattage, and the iPhone 15 can charge just a bit faster than 15W, while the Galaxy S23 Ultra can charge up to 45W. You need power for your phone: The 3,000mAh battery inside is plenty to keep your Apple Watch going, but that isn't enough power to get you even halfway charged on an iPhone 15, and even less on bigger phones. You don't need all those extras: The Anker Prime power bank is pricey, and if you don't care about monitoring charge Wattage or days of battery life, find another option.

There are plenty of other power bank makers around, and most of them have not caught up to the faster charging speeds available on the iPhone 15 family, let along even faster Android phones. Except for unique form factors or serious bargains, we stayed away from recommending power banks from reputable makers if they couldn't charge at 2023 speeds.Everybody on our gift list who got a new iPhone is going to get an Anker Nano Power Bank (22.5W) this year. This cute little charger is perfectly sized to sit beneath your favorite smartphone, plugged into the USB-C port with a little plug that opens out or hides away for a sleek look. The answer to this will depend on your needs. Small power banks can be great for an occasional top up of power on the go – they’re light enough that you’ll hardly feel the weight of them in your bag. Large models give you more juice, but are less portable.
