Overview
A 2-pack of slim 10,000mAh power banks with bidirectional USB-C plus dual USB-A ports, built to charge up to three devices at once. Each bank weighs 7.68 oz and carries a flight-safe 37Wh rating.
The USB-C port does double duty here, both recharging the bank and outputting power to a phone or tablet, which simplifies which cable to pack. At 5.5 x 2.6 x 0.6 inches each, the pair is meant to be split between two people or kept one at home and one in a bag, and the 37Wh rating stays within typical airline carry-on limits.
