Hand-pumping an airbed or inflatable sofa gets old fast. The Vango Mistral takes care of it in minutes, shifting air at 220 litres per minute in both directions, so it inflates and deflates with the same unit.
It comes with a set of nozzle adaptors to fit most standard valves, and charges up via USB, so there's no need to find mains power or run it off the car battery — a power bank or any USB socket will do.
