I have been looking at this inflator for a while, it came up on Amazon for $99 around black friday so I finally splurged. I have an excellent Viair compressor that I carry, but this Dewalt is so convenient I might start leaving the Viair at home.
This is a great tool.
My battery powered tools are Black and Decker and I have their version of a tire inflator. I'm sure they're all mostly about the same but I'm really happy with mine. I'm much better about checking my tire pressure when I can conveniently do it at the campsite instead of having to make an extra stop somewhere.
I use the Milwaukee 18 volt tools. When I needed new batteries, I stopped at a Home Depot Wilwaukee sale, bought the batteries and got a free inflator. It works great and isn't too heavy. Beats the heck out of maneuvering my trailer up to an air station at Costco or a gas station. The Presta attachment works fine on my bikes too.
I have a Dewalt and a Ryobi inflator. Both perform great.

We have Ryobi tools at home and I love our inflator, though they keep redesigning it. Would not travel without it.
At work (I work at a Museum) we have DeWalt and I am getting this inflator for our new custom Mack MD6 box truck we just picked up.
I'm a Makita fan but my Cat Power Pack also has a inflator so the Makita may now stay home.
I have (had) a Dewalt until it stopped working. Error code E5 - bad pressure sensor. Replacement part unavailable. Liked it while it worked.
@TxBrian if you are courageous, this video may help.

I'm also a Makita fan. How do you like their inflator? I'm considering getting one.
@Slotown Thx ! I actually did the recommended repair in the video (replace relay). The unit powered up but that’s when the ER-5 error code popped up. But I haven’t given up ! Still researching for pressure sensor repair
Years ago, testing a 70 dollar inflator (Goodyear brand), I deflated a 17" dually tire flat to the ground and timed bringing it back to 80 psi.
It took over 20 minutes before the 80 PSI was reached. The 12v cigarette lighter plug got so hot it melted to wires going to it and burned up the receptacle, not to mention blistering my hand when I unplugged it. 
A high dollar one ($200-300+) that clamps to the battery is not going to fall short if you intend on inflating anything larger than a SUV or trailer tire that operates in the sub-50 PSI range and isn't as large of a volume as the full-size truck tires. Otherwise, about any little compressor is fine if you don't expect it to do that.
.
My Dad had one of the $30(red), now $70(blue) compressor. Just taking truck tire from 90psi to 110psi took forever and tripped thermal protector several times. They now offer one twice as expensive and a little smaller, that's rated for 200psi.
