If you detect high temperature at the plug or outlet, let it rest a few minutes. Best to use an adapter to connect the plug to battery clips, or remove the plug and install clips. These are commonly available at Radio Shack, auto parts stores, and probably Home Depot. Watch cord length! Long heavy cords with clips are best, but are seldom provided.

Tire pressure is so important. I need something that won't take all day to air up these big tires that can plug in somewhere in order to get to all six tires. The motorhome is 35 feet long. Any suggestions?

Rated 4.8 out of 5 by 25 reviewers.
Rated 4.0 out of 5.0 by Good quality Product Ordered after reading the reviews. Arrived on time and in good shape. Like the product and does the job well. February 16, 2016
Rated 5.0 out of 5.0 by nice little compressor Works great does the job. Comes in handy.no need to go to the gas station anymore. February 1, 2016
Rated 5.0 out of 5.0 by Excellent Quite impressed with the quality compared to other air compressors I have owned. All metal head and body give it the feel and actions like no other air compressor. Maybe a bit bigger than others but it makes up for size with its ability to perform. Great air output in short time, quiet and stays standing on the rubber feet unlike others and the screw on hose lets out Zero air while screwing on or off. You cannot go wrong with this purchase. October 27, 2015
Rated 5.0 out of 5.0 by High quality product I needed to replace a portable compressor from a different manufacturer when it stopped working. The VIAIR is far superior. It's solidly built, quiet, and fills my car's tires in far less time than my old one. Only downside: you need to have the car's engine running to use it. September 29, 2015
Rated 5.0 out of 5.0 by 12-VOLT PORTABLE COMPRESSOR seems well built, a lot quieter than the black and decker or kobalt compressors i had have only had to use it 2 times. 1 mower tire at half pressure filled very fast. 1 car tire 10 psi low i had to top off also very fast. September 15, 2015
Rated 5.0 out of 5.0 by Great product Quick to inflate the tires and the cord was just the right length. September 22, 2015
Rated 5.0 out of 5.0 by Solid compressor This little compressor is more than I expected after purchasing a cheaper model years ago. The unit is quiet, small and portable. It will air up a flat tire quickly. July 21, 2015
Rated 5.0 out of 5.0 by Very nice product. I have a slow leak in one of my tires that has had me stopping once a week to fill up. On occasion, I will come out to the car and the tire is flat. Based on my model of car, I know it is rim leaks and taking it to a tire shop means they will reseat the rim, which may do more harm than good. I purchased this compressor to have should I be stuck, and man does it deliver. Topped my tire off in seconds. My only complaint would be that the built-in pressure gauge read different than the trusty one I've been using for months. Will be getting another gauge to verify which is wrong, but I bought this product for it's inflating capability and not for it's gauge, so I am not concerned about that. Very happy with the purchase, will recommend this product every chance I get. March 25, 2015
