The most important thing to do is to match the battery’s output to your phone’s input. For example, if you have an iPhone, be sure the battery has its own Lightning connector or supports USB-A-to-Lightning or USB-C-to-Lightning cables.
Quality-of-life tweaks include two hidden handles for easy movement and the presence of all output ports on a single side. Like most of our other recommendations, there is also a built-in LCD screen to keep an eye on the device's vitals. Using the Anker Prime power bank, we were also able to test the charging speed claims of other power banks, as the Anker Prime will report charging speed in wattage. Some power banks have multiple ports, allowing you to charge multiple devices at the same time. Anker power banks use standard USB (USB A) and USB C; newer models charge through USB C ports. The next question is how you want to charge your device. You can find a power bank that charges your phone (or even your Apple Watch) wirelessly. These will usually charge slower, but they can be very convenient if you want to leave wires at home. That's a bit of a jump up for the Anker product, but generally it's worth paying that to have a power bank from a more trusted brand.
The World's No. 1 Mobile Charging Brand*
This is self-explanatory, but some of these batteries get pretty boxy and chunky. The dimensions and mass matter, as we assume you’ll be bringing a portable charger with you for the day.

Among other features, there are 12 output ports on the power station, including three AC outlets, two 100W USB-C ports, three 18W USB-A ports, and three DC outlets, allowing you to run or charge multiple devices simultaneously. There is also a Qi charging slot for wireless charging. There’s a good reason the GH Tech Team added this model to our list of the best power banks: it gives you a big capacity without the size (and high price) of the more imposing Anker 737, although if you do fancy it, there's a 36% on that model, too.
USB-C charging gives you the power you need to charge up your iPhone 13 to 50% in just 28 minutes—that’s up to 3 times faster than your old 5W charger. The most important question to consider when buying a power bank is what will you be charging? If you are charging a small smartphone and that's all, a simple power bank will suffice. If you plan on charging a laptop occasionally as well, or many devices at once, you'll want something with more power and more features. There are also cool additional features to consider. Our favorite power bank has a built in charging plug so it can go right into a wall outlet. Some power banks have data about your charging devices. Some are just super small and cute. Which power bank is the best quality? In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty. When you’re looking for a power bank, there are a number of factors you need to consider.

In fact, our testing confirms what battery makers usually claim. A battery maker will claim between 60% and 70% efficiency, so that 10,000mAh battery will only give your phone around 6,000mAh of extra battery charge, at the least. In practice we find around 65% efficiency, though occasionally we can do even better. Anker 313 Power Bank (PowerCore 10K)- Anker’s 313 10000 mAh power bank is a wonderful travel companion. With an astonishingly sleek and lightweight design, it is equipped with Anker’s world-renowned PowerIQ technology along with MultiProtect Safety System, which effectively delivers a power boost and lets you rest assured of safety anywhere you go.We expect this competition will heat up next year as more power bank makers catch up and make faster charging batteries. Until then, Anker is the dominant brand, and if you want the best it's an easy choice. How many times can my power bank charge my phone? Read the Instructions: Take a few minutes to read the user manual that comes with your power bank. Familiarize yourself with its features, usage instructions, and safety precautions. This will help you make the most of your new gadget while keeping yourself and your devices safe. You’ll have noticed that we list the battery capacity in milliamp hours (mAh) throughout this roundup, and it’s worth using this as a guide to the charger size you’ll need. The bigger the number is, the more capacity it has. Of course, phones all have different batteries too.
