Portable dc air compressor

[Hoopy Frood]

I have the Dewalt 20v, I have only used it a few times so far but I am happy with it so far. I am not sure the max pressure but it didn't sound like it was struggling at all for my 70PSI and it can also inflate toys / mattresses etc.

I believe the max pressure is 160 PSI, but it would take a while to get there. I've used it to inflate the trailer tires from 95 psi to 105 psi, and it does get the job done, albeit not quickly. It's actually fairly quiet for a small compressor/inflater. I have several Dewalt tools at home so it makes sense for me. I like its small size too.

I'm cheap and retired, I have plenty of time to sit around and watch my $50 craftsman so it's job. Of a tire needs that last 10 lbs it might take me 6 minutes, but that's OK. Just enough time to get into the forum and check things out.

I've had a $60 Black & Decker inflator for 5 years. It does both high and low pressure, so tires and floats. It's a bit slow on my 80psi tires and the 12v plug likes to vibrate apart and lose the fuse. It might be wearing out...

Does EVERYONE have a Viair 300 or 400? I like the 300, good for my needs.
Is Viair the RV'ers choice or are there other good options?
I was considering the Dewalt 20v air compressor but can't find info on max air and speed.

Thanks

I have the 400. I was going to get the 300, but I am glad I got the 400. When I bought the 400 I also had a 303
RLS and the 300 would have been good enough but, now I have a Solitude 310 GK and the 300 would not make the 125 lb tires on the 310.

Viair 450RV for me. Love it.

Viair 450RV here when on sale at Techno. But, I did order a portable hand held for adjusting pressure on the Goosebox.

I have the Viair 450. We’re moving & don’t have access to my garage compressor yet & used the 450 for all my needs.
I do like the different attachments for inflation, especially the one I use for the inside tires on the dually. Came with two coil hoses & reaches the trailer tires.

One of the main reasons I got the 400P automatic is to make it fast/easy to fill/recheck pressure in the duallys.

While this version has two air hoses that can extend the length of the truck/trailer I can get away with just one when hooking direct to the trailer battery.

I ran a 12ga wire with these quick connects from the trailer battery routed out to the propane compartment on the 5er. This provides quick access to trailer power that is high current to support the compressor.

I carry the Milwaukee, work great, and use the battery for other tools.
