I bought this for our van especially for long trips. Although the product description claims it can withstand 150psi of pressure, actual physical testing does not. When we attempted to test it on our van, our van required 50psi on the front wheel and 70psi on the rear, and barely reached 50psi at maximum power even though it was fully charged, so it was barely enough for the front wheels. and certainly not enough for the rear wheels. Not something I would trust, especially on a long trip you need gear you can trust. Decided to return and look for something else.
