A great pump that's worth the extra cost.
This pump is fantastic. I'm impressed at the size of tires, the speed, and the pressure that this pump delivers.Well or if it's money, I bought one for each car.

Put your skepticism aside and buy this! You will never regret it!
My wife and I have been living the RV life full time for six years now. A friend of mine bought this and highly recommended it. I have been hauling a Sears compressor around for those years. Need to air up? Break out the shore power or a generator. Not so with this amazing unit. We had been parked for a year while I built a parking garage. The tires were down to 60#s. It took 21/2 to 3 minutes per tire to get them to the 80#s needed per tire! When you look at the unit you laugh and say no way! Then you hook it up and become flabbergasted! It works perfectly. Thank you for such an awesome product. I highly recommend it! You will never be sorry!

perfect for 24v dual battery.
i bought this for my HZJ77 land cruiser which happens to be a 24v system. works perfectly so far. i've only had it for a couple months so we'll see how long they last.

Fills 35s fast!
Used this pump many times after airing down to drive on the beach. After about 2 years it seems like the pump pulled metal particles into the cylinder and destroyed the gaskets as well as cylinder wall and pump no longer builds pressure.
