Review on HONGNAL Portable Air Compressor Tire Inflator, 150PSI Car Air Pump Compressor 12V DC with 4 Nozzle Attachments, LED Light, Air Hose, Battery Clamp for Inflating Car Tires, Bicycles, Trucks & Inflatables by John Hall

This tire pump looks solid. The air cylinder is made of steel; The rest of the parts are mostly plastic. The pump can be connected to the on-board power socket or directly to the car battery using the adapter supplied. It has an integrated air tube that can be connected directly to the tire. There is also a recoil air hose that connects to the built in air hose to increase range. All in all, this pump does what it is supposed to and does it very well. Here are some of my pros and cons: Pros: - Pretty fast pump stages. - Much quieter than other tire pumps I've used. - Accurate pressure gauge; Compared to two standalone tire gauges that I know to be accurate, this pump's gauge consistently reads 1psi or less. - Has built-in LED indicator with separate switch. - Has 4 rubber feet to dampen vibrations. It's petty but nice. Disadvantages: The air hose is connected to the tire valve via a brass threaded connection. I prefer the lever operated air chucks found on most bike floor pumps. They connect and disconnect much faster and there is no risk of accidentally twisting the brass connectors - The connection cable and air hose are too short. When connecting to the auxiliary power connector on my Honda CRV, I had to run an air hose through the front door on the driver's side for the driver's side tires and through the front door on the passenger's side for the tires on that side. A similar inconvenience when connecting the pump directly to the car battery. When connected to the battery on my Ford F150, I can barely reach the rear wheels with the recoil hose fully extended.
