I really like this 2-port USB-C charger.
This Anker portable charger is currently on sale.
USB power bank vs. cordless power tool battery and USB charging adapter? Which do you prefer?
The Anker PowerHouse is a portable battery bank that’s equivalent to (6) 18V 4.0Ah battery packs, and it sports an AC outlet, 12V auto outlet, and 4 fast-charging USB outlets.
