Picked up an MV50 at Oreily's a few years ago for $49. Works fine. Had problems blowing the in-line fuse. Now I keep 1/2 dozen in the bag.
Used it Saturday to air up 30x9.5 from 15 to 40 front and 15-35 rear. Didn't blow a fuse. It seems to only do that with repeated on/off cycles while checking the gauage.
A finally fiqured out the guage reads +10 psi higher than acutal psi when the unit is turned off. So...I watch the guage while it's running and shows approx +10psi over my target psi...then shut it down and move to the next tire.
Hope that helps all you other MV50 users...
Yeah mine is that way too but only about 5 psi off. Once you figure out how much it's off it's pretty simple to use. Have to say the MV-50 is likely some of the best bang for the buck money Ive spent on my rig.
funny how some of these products get *inflated* so fast (sorry, couldn't help it). i looked into both the MV-50/MF-150, can't find ether for less than $78. how did these go from $25 to $79!!!
I have a new MV-50, out of the box but never used, will gladly ship it in it's new home (mil spec night vision case) if anyone can't get there hands on one.
Thanks

I have an MV-50 also, and it seems like a good compressor, but I don't care for the connector on it much, I plan on changing it for a standard chuck. Still, the compressor and hose/chuck change is still under $100.
I am one of the few who has had problems with the MV50. I have had 2. The first one never did work, so it was exchanged for another. The second one works when it feels like. Sometimes getting such a poor connection it actually deflates the tire even when on. These were both from a few years back, so they may have gotten better since then. If i could find one for the old $25 price, i might give the newer model a try. I'm still using my $15 Kragen Auto Truck Air Compressor that i have had for 8 years. It's slow, but has never let me down.
A Weller butane soldering iron is a standard part of my toolkit although I no longer solder connections that aren't soldered at the factory. They're better at handling off road rigors when crimped.ive got one of the butane models too. works so well i dont even bother with the electric anymore.
For many years, I've used a hand pump to adjust tire pressure. $20, lightweight, and nothing on it to break.

Heh, "adjusting" air pressure is one thing...going from 12 to 35 psi on four 35" tires is another.
I regularly use it to make 15 psi adjustments on 345/30/19 tires, which are pretty big for car tires.
Not nearly as much volume as in a big offroad truck tire, though, so you're probably right about it being a bit undergunned for that use. (I use an ARB compressor for my truck tires.)
