RYOBI P737 18-Volt ONE+ Portable Cordless Power Inflator. I had a couple of batteries from a Ryobi mower. On sale one day for cheap for the tool only at Home Depot so it was worth a try. Works great. .5 off from a Topeak digital pressure gauge I have using for years.

 

Did the same thing due to already having several Ryobi tools and batteries. Got mine yesterday on sale. Amazing how fast it is for being so small. Hydro Flask not included.

 

Milwaukee m12 pump, if you are already on the battery platform its an excellent addition. Come to think of it maybe you could adapt a 12v battery pack to that Viair pump.

I just need my pump for topping up tires, not for offroading. So take my experience and recommendation with that in mind.

 

I have been researching this and I have found that if you are looking for cordless then either Milwaukee, Ryobi or Dewalt are the way to go... they are about the same and depending on which you have batteries for already, you should go with that one.
I have Dewalt and thus am waiting for the Dewalt unit to go on sale - it's typically $99, so I am waiting... Lowes and Amazon both seem to have it most times or on back order.
The Dewalt has the added benefit of being able to be powered from 12V or AC power too... and has two nozzles - one large and the smaller for tires.
I think it's going to depend on what your needs are - looks like you went with a clamp on battery style...with a model i came across also and considered until I came across the cordless options which i can use away from the vehicle also.

I never really considered this. What a great idea. I have Ryobi ONE+ (and their 40V yard equipment) so this is a no-brainer.

Does that work on car tires? Ryobi doesn't recommend it for car tires, but if it would work, it's much smaller than the next one up in the line.

I like the Ryobi P747. It's faster/easier for tires and way better for air mattresses/beach toys:

Almost just bought this one. Still might.

 

I just got the Dewalt one for airing back up after offroading. Haven't "used" it yet, but quick tests show it to be very nice!

 

I, too, have the Dewalt battery platform so this was the logical choice for me. I love how you can set the pressure, turn it on and it will shut off by itself while I tend to other things. It also has a low-pressure, high flow function for inflating rafts and such. This feature also works well for blowing off sawdust from me, my saw and workbench. I got it at Christmastime for $79 from Home Depot including a battery. Currently $99 on Amazon, sans battery.

Some days I wished I had gotten into the ryobi tool platform, lol. Milwaukee makes some good tools, but you pay for them.

 

I’ve never fully inflated an empty tire, but I’ve used my Ryobi to refill a half empty tire after plugging one of the OEM tires last year.

 

Now that is quite an air compressor, very impressive. I keep one in each car, can't recall the brand at the moment but I picked them up in Costco about three years ago for $30.00 each. The body is all metal.

 

I have that exact Viair pump. Bought it on 2013 to use for monthly autocross events in my Mazdaspeed 3. Has worked perfect every time for 8 years now. It now rides in the ascent as it's our daily. I think you'll be happy. Why worry about a battery device when you have a car battery?

 

How is the battery life on the battery powered ones? Can you air down for off-road then reliably air back up with them? This is mostly directed toward anyone who has had them for some time. Batteries are all great when new, but as they go thru charging and heat cycles the capacity diminishes.

 

I have a husky corded inflator, but wanted a cordless one for our travel trailer. It's not necessary, but extremely convenient and given the limited aux power port availability on the ascent and my legacy it made sense. But again I'm not offroading, for that something with more gusto makes complete sense. Also fwiw modern lithium packs lose negligible amounts of capacity over their life time, the quality of their cells is what matters, milwaukee, dewalt, and ryobi are all good quality. Probably better than the battery under the hood...if oem then definitely better, lol.

For the milwaikee 12v a 1.5ah pack is good for inflating my ascent tires from 33 to 45 on all 4 with 1 bar left, or 1 225/50/18 tire from completely flat to 33 psi and about half a charge left. Ive also got a 6ah pack which would be plenty to do all 4 tires from flat with appropriate cooling periods.

 

P747 - I have lots of Ryboi batteries, set the PSI and forget it. Easily find these on sale for under $40, I inflate camping beds too.

 

I picked up the 85P recently and wired a socket for it to a dedicated 20A circuit I added to an unused port in the fuse panel for my inverter. i didn't want to deal with battery connection and hood opening while using and the draw is theoretically a little high for the factory accessory port. i also purchased this 6 foot viair extension hose and it all fits in the case that comes with the pump. 85P is the thread on version so the hose more or less permanently mounts in line to the stock hose. i don't have an cache of batteries from other tools to pull me toward rechargeable.

this replaced a 20 yr old cheap 12v pump I had been carrying around for emergency use that took 10 minutes to bring each tire up from 18 psi to +30 after a beach day. then after 3 tires it was running but topped out ~25PSI due to getting hot. If you plan a day off road or in the sand airing down definitely trial run your air up strategy. Family wasn't too much into a 40 minute air up routine and then still looking for a roadside pump for the next 10 miles (every single one broken due to overuse).

 

I bought the Dewalt DCC0201. It is Awesome. Works with all my 20V Vmax batteries. Hook it up, set the pressure and hit Play. Battery life on the smallest 2Ahr battery is great. It has a great LED light to brigh the work area at night. It fits under lid in the cargo area as well.

I have the Dewalt Inflator too. Fantastic tool and even thought I have a compressor the inflator is my go-to tool when I'm checking tires. Worth the money.

(borrowing the pics above, thanks)

I use(d) both the P727 (died finally, but still under warranty - just need to find the receipt) - it does not have a "set pressure" feature.

and the P747 - one of my favs, as I ALSO use it to pump up my air mattress when camping.

I prefer the P747's ability to set and walk away. The Ascent Touring's 100W AC inverter is powerful enough to charge them using any of the standard Ryobi One+ chargers.

I also use this, which is also settable, and very small, yet as fast as the two above (12V accessory outlet required for use - it is not battery)

Another vote for the Ryobi P747. Ryobi also makes so many other tools using the same battery such as their fans and lights, great to take on a camping trip.
