Brick · power bank

Brick puts the number on the outside. A small monochrome display shows watts in, watts out and the charge left as a percentage that comes from the cells rather than from four dots and an optimistic guess. Two USB-C ports, 100 W from the first one, enough for a laptop and not only a phone. The cells are named on the spec sheet and on a label inside the case, and the case opens with four screws rather than ultrasonic welding, so a dead pack is a recycling problem and not a landfill one. The corners are moulded TPU because a power bank lives in the bottom of a bag with keys. Airline-safe at both capacities.
