About this product
The VIAIR 400P-RV Automatic Compressor is a portable, single-stage air compressor designed for RV and automotive applications. Powered by 12V battery, it delivers 1.75 CFM at 40 PSI and 1.28 CFM at 90 PSI. Featuring an oil-free pump and a 0.5-gallon tank, this silver unit includes an air hose with fittings, making it ready for immediate use. Its compact design and automatic operation cater to on-the-go inflation needs.
Our take
This VIAIR 400P-RV compressor is a solid choice for anyone needing a portable air source, especially for RVs. The 12V battery power makes it incredibly convenient for roadside use or camping trips where a power outlet isn't available. I appreciate the oil-free design, which means less maintenance. While the 0.5-gallon tank is small, it's really intended for topping off tires or small inflatables, not for running air tools. The 1.28 CFM at 90 PSI is decent for its size, but don't expect rapid inflation of very large tires. The inclusion of an air hose is a nice touch, adding to its grab-and-go utility.
