The Flextail Zero Power 5000C is an ultralight power bank for hikers, runners and climbers. It weighs just 85g (3oz) and is only 7.1mm thick, thinner than most phone cases.
A forged carbon fibre shell gives strength at a very low weight, and a flame-retardant, fibreglass-reinforced nylon frame adds extra protection.
