You’re a nomadic person. Nothing makes happier than being out on the open road, the pavement beneath your RV tires, traveling to your next great adventure. To make sure you and your RV or camper trailer make it to your destination in time to enjoy the scenery and avoid nasty, trip-stalling flats, the 450P-RV Automatic Portable 12-Volt 150-PSI Air Compressor from Viair is your go-to machine. Few things can ruin your big trip more than discovering one of your RV or camper trailer’s tires has gone flat before you’ve even begun. Especially when you’re setting off cross-country for the latest national park you want to visit or wanting a relaxing weekend camping at the lake. Only thing worse is having the flat tire happen along the way. With the 450P-RV Automatic, however, you’ll never have to worry how far the air service station is or waiting for that expensive RV AAA service because you’ll have your own heavy-duty automatic air compressor right there on the road. Viair’s portable automatic air compressor conveniently clamps to your motor vehicle’s battery no matter where your worst flat-tire nightmares happen. This portable air compressor features a permanent 12-volt magnetic motor capable of 150 PSI max operating pressure. That means you can fill your RV tires from 80 to 90 PSI in under 60 seconds, meaning you can avoid long periods of time working along busy roadsides and get safely back on your way to your destination in minutes. The best feature of this portable tire pump is the automatic shutoff, which unlike typical portable air compressors that must be turned off between tire fills and pressure checks, allows you to keep the air compressor running as you check tire pressure or move between wheels. You could spend just as much time running back and forth to flip the on/off switch as you do putting air into your tires, or you could just use 450P-RV Automatic—the automatic portable air compressor that can operate for up to 40 minutes straight and get you back to your next great travel excursion. With a wide range of features, from vibration-resistant sand tray for added stability, gas-station style inflation gun with inline 160-PSI pressure gauge for convenient pressure reading, 45- and 90-degree air chucks, and 60 feet of air hose to reach even those difficult rear dual wheels easily, this automatic air compressor has it all. Don’t let the specialized portable proficiency of this powerful automatic air compressor scare you, though; the myriad of accessories included with this portable tire inflator is perfect for virtually any size tire in your life, even when you leave the big rig at home. No matter where you’re headed, don’t let a lousy flat tire ruin your big trip. Trust the 450P-RV 12-volt automatic air compressor to keep you on the road.

What I always needed

I was looking for something I could keep the tires of my extra car (that I keep on the street) filled up. Because the vehicle sits a lot the tires are always dropping pressure. It takes too much to hook up my portable compressor and run electric down…

Nice Unit

I would make the filter a little more secure than screwing in the end of the unit. Also, I think this unit would be a great candadite for a hard case carrying apperatus. aside from that it works as advertised.
