How We Tested

We have tested and compared the performance of each power bank, looking at a few key areas to find the best power banks for our roundup.

Size

Instead of measuring each power bank’s length, width, and depth, we estimate the size relative to the device that fits best in a wallet or pocket. We check compatibility using different sizes of bags and accessory pockets.

Weight

We use a digital scale to confirm whether the listed weight of each power bank is accurate or an estimate.

Look And Feel

The external appearance is also a vital measurement factor of a power bank, and the texture should be smooth and stylish as it is a practical accessory. On each device, we reviewed many intuitive features such as power buttons, built-in cables, charging status lights, flashlight, pop-up AC plug, etc., on each device.

Charging Output of USB Type-C Ports

We measured the output of the USB Type-C outlet with 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 plot the volts and amps to measure the input in watts.

USB Type-C Recharging Speed

We verified the USB Type-C charging input by connecting a fully discharged power bank using a Total Phase Power Delivery Analyzer and a 60W MacBook Pro charger. We plotted the volts and amps to measure the input in watts.

Micro-USB recharging Speed

We checked the micro USB input by connecting a fully depleted power bank to a Portapow USB power monitor an Anker PowerPort 2 wall charger to record the volts and amps recorded by the Portapow and calculate the charging input in watts.
