What’s the Best Charger/Power Bank Under $30?

In this Project Farm video, Todd looks at portable power banks. He tested models from Anker, INIU, S22 Mini, Miady, LOVELEDI, IXNINE, KEOLL, CFIAI, iWalk, FEOB, Baseus, Durecopow, Erkrist, MREGB, RGVOTA, and GOODaaa.

The power banks were tested for maximum output wattage from USB and Lightning ports, maximum mAh/Watt Hour capacity, and the amount of time it took to recharge the completely drained power banks.

So, which is best? For under $20 ($17), the Keoll got straight As. At only $20, the INIU charged quicker than the Keoll and has slightly more storage capacity (32.8 Watt hours vs. 26.6). The Cadillac of power banks was the Anker ($92) delivering a whopping 69.7 Watt hours).

  1. I’m a huge Adafruit fan and would like to point out to other Adafruit customers that if you’re going to use a power bank to power your electronic projects, you may want to make a USB-C output port a required feature when shopping. Some microcontrollers sip such low power that power bank ports with the older USB protocols (USB-A, micro USB) will shutdown after a few moments. I found this to be the case for my projects based on Particle Photons and Boron’s. However, power banks with USB-C output ports work great!
