AstroAI CZK-3631 (AIRUN H) 12V Portable Tire Inflator
Topping up car, motorcycle and bike tires from a 12V socket
The CZK-3631 is a 120-watt pump that plugs into a 12V outlet, takes a preset pressure and stops itself when it gets there. Its manual caps continuous running at 15 minutes and asks for a 10-minute rest, and its air hose is only 50 cm — the 9.84 feet in the listing is the power cord.
