How We Tested

We tested and compared the performance of each power bank keeping a few key areas in mind to look for the best power banks for our roundup.


Instead of measuring the length, width, and depth of each power bank, we measured the size in terms of the best device to fit in a wallet or a pocket. We checked the compatibility as per different pocket sizes and accessory pouches.


We used a Digital Scale to confirm if the advertised weight of each power bank is accurate or estimated.

Look And Feel

Exterior looks and feel is also an important measurement factor of a power bank. The texture should be smooth and stylish as it is a handy accessory. We checked numerous intuitive features like power buttons, built-in cables, charging-status lights, flashlight, fold-out AC plug, etc. in each device.

Charging Output of USB Type-C Ports

We measured the output of USB Type-C output by using a Total Phase Power Delivery Analyzer and connected it to a half-charged power bank, a MacBook Pro and an Apple USB-C cable. We recorded the Volts and Amps to measure the input in Watts.

Charging Output of USB Type-A Ports

We measured the reliability of USB Type-A output by plugging in a half-charged power bank to a Portapow and a Drok USB Load Tester to check the Volts and Amps recorded by the Portapow to measure the maximum output in Watts.

USB Type-C Recharging Speed

We checked USB Type-C charging input by plugging in a totally drained power bank with a Total Phase Power Delivery Analyzer, and a 60 W MacBook Pro charger. We recorded the Volts and Amps to measure the input in Watts.
