Whether you are headed on a road trip or you write in a coffee shop, a power bank can help your devices stay charged. In order to find the best power bank for your needs, consider the type of charging you will be doing and how many devices you it want to serve.
A power bank’s capacity is measured in milliamp-hours. 10,000mAh represents roughly 1.5 full charges of a new smartphone. You can find small 5,000mAh power banks that attach directly to your phone to increase the time needed between charges, power banks with 30,000mAh and higher for keeping numerous devices charged, and everything in between. Additionally, you may notice that power banks list wattage. The higher the wattage, the faster the power bank will charge your device.
Finally, there are many different charging interfaces, including magnetic phone chargers for easy wireless charging. And some portable phone chargers include built-in charging cables so you won’t have to carry separate charging cables. For laptops and some other devices, you need an AC port, which is only offered in some of the larger power bank designs.
