So my son and I bought this cool little gadget the other day. Ryobi had just dropped this new little compressor and I wanted to see if it handle the airing up of the Powerwagon tires. We take a few of the Ryobi 18 volt tools when we go camping so I plan to have the batteries and charger with me anyways. It also gave me an excuse to upgrade my batteries to the bigger, 4Ah ones.
It's got a tiny little one gallon tank and takes 30 or so seconds to fill itself up to 120psi. It's fairly quiet. I'd say a little quieter than the portable 12volt Viair or ARB. My test was seeing if it could pump up one of my 35x12.50 r17 's from 30psi(what I usually air down to on the trail) to 60psi(what it takes to get the TPMS to stop yelling at me). From full, it took 1:20 to get to 45psi. Thats about where this thing starts hitting it's wall. Once my tire got to 50psi it just seemed to sit there. I stopped airing the tire and let the tank fill. It took 2 more bursts to get the tire up to 60psi.
I ran the test twice and the battery shows a 3/4 charge so it's possible it'll make it through all four tires. If 30-35psi is your street pressure this thing is perfect. 60psi......ehh it'll work but nothing amazing. I think I'll keep it around the shop and I'm curious if playing with the output regulator can help.
From what I have heard, Milwaukee warentees their batts for life. Mine are all Dewalt 18v. The new 20v dewalt tools are not up to the quality of the 18v, not made as durable. GRRR. I have batts that are 5-6 yrs and still going, I use the dickens out of them, I have 7 batts. I used to have Ryobi and ended up throwing them out because of battery failure, but that was 1st gen 18v. Maybe new gens of batts are better.
I started down the Milwaukee path, There's actually 2 variety's of tools though the M12 and M18. At least most of the chargers do both. Great selection of tools, really happy with the Mid-torque impact. Figured if I need more than 600 ft/lbs, I probably should be paying someone else to do it (correctly). Their big one will do 1400 ft/lbs. They sure are proud of their batteries though.
I also picked up a new 18volt impact wrench. Tested it out on my 130 ft/lb lugnuts. works just like my air tool....I think I'm going to add a new inverter and wire in my extra battery charger.
Yeah, staying in the same battery ecosystem is the way to go if you can. The batteries are the most expensive part, once you have a couple (or maybe just stick with 1) the tools themselves aren't too expensive
Green Works has a similar one that caught my eye that runs on the 40v batteries I already have for their chainsaw. Fairly inexpensive too....hmmm
Its amazing what these lithium batteries can power and all the cool tools that are being developed. Corded tools are really becoming dinosaurs
