Product Description

The VIAIR 400P (40043) - 12 Volt Portable Air Compressor for Truck Tires Enjoy peace of mind everywhere you go. The 400P tire pump for trucks, SUVs, RVs and more is portable and lightweight, with a maximum dimension of 10.87 inches and weight of 10.4 pounds.

Electric Truck Tire Pump with Carrying Case Conveniently stored in a durable canvas carrying case with top handle, the 400P portable air compressor for truck tires is ready to use at any moment, whether you're at home, stopped on a busy roadway or out in the middle of nowhere. Compatible with All Vehicles From trucks and SUVs, to motorcycles and side-by-sides, this tire pump with pressure gauge is portable and powerful. Fills a 35" tire from 15 to 30 PSI in 2 min. 45 sec or less, the 400P gets you back on the trail in minutes, no matter what rig you drive. Fast & Easy to Use – No Programming Required Attach the alligator clips to your vehicle's battery terminals, start your engine, connect the air hose to your vehicle's tire, and power on the unit. The 400P relies on a simple On/Off switch. Simply monitor the pressure gauge and fill to your desired pressure. From Road to Trail VIAIR's battery powered air compressor pumps are loved by daily commuters, families, and extreme off-road enthusiasts alike for their powerful, reliable performance in a small package. 12V Battery Clamps for Higher Performance Offroading applications have higher performance demands that cigarette lighter plugs are unable to meet. Enthusiasts prefer direct battery connections for their trucks, Jeeps and 4x4s because it accommodates the increased current draw of larger, more powerful compressors. While VIAIR does offer cigarette lighter models, we recommend compressors with battery clamps for serious for offroad use.

About Compressor Duty Cycle
Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

    4 Stars
    Overall satisfied
    The pump itself is great and you can tell it s a quality product but the hose is really not useful.First the gauge is next to the tire you inflate so you need to go constantly between the pump and the tire if you want to adjust the pressure with the pump. The best is to inflate with a higher pressure and then deflate to get the desired pressure.Then the connector to the valve tire is with a 90 degree angle which makes it really hard to connect as it needs to be flush with the tire rim. I ended up making a new hose with a straight connector. It s more compact and a lot easier to connect.I also added quick disconnect at the pump with a digital gauge equipped with a deflation button so that I can adjust the tire pressure at the pump. I got everything from harbor freight for about $20 and it makes the system prefect. I don't know why they don't do something like this.Be also aware that this model doesn't automatically stop of you have an overpressure so make sure to only buy open flow fittings or valves. The 400 automatic has a pressure switch that stops the pump, so if you want to use an air pressure gun get the 400 automatic, not this one.
