Things they don't tell you, or written in fine print.
-Not meant to inflate a fully flat car tyre in one shot. 5 minutes on, 5 minutes off to cool off. It gets VERY hot, it's meant for monthly topping off, or for emergency when you have no other option.
-Not meant to be left inside vehicle because it may overheat the batteries during hot sunny days.
-Batteries are not user replaceable. Once they die, that's it.
-This is basically for inflating your air mattress (or inflatable doll, or so I've heard) basketballs, etc.
Get one that connects to your 12volt socket or a Ryobi compressor, or similar tool (if you're a Ryobi head)
Their specs look dubious. If it takes 2 min to do a bicycle tire, it's not going to do a car tire in 4.5min, and there's no way it does 30L/min (slightly over 1CFM) at 80PSI. It takes a cylinder closer to tennis ball size and about 300W+ motor to manage that.
The trade off for this small cylinder form factor is very slow inflation. It's unlikely that you'll be able to top off 4 vehicle tires, by the time they are low enough for the TPMS, let alone your eyes to notice, without having to stop and let this cool down, then restart one or more times.
I had a popular one that connected straight to the vehicle battery, MF1050 aka MV50, probably over 5X faster than this, and was happy with it for a while, but it kept breaking even though it never ran for long enough to overheat.
Trying to estimate total running hours on it before retired, probably under 3. Decided a small air compressor and hose was a better solution, one rated at 3000 hrs. 1000X longer lifespan is a much better value to me, and I can use it to bead-seat tires on small wheels (among other things) which is something no tankless inflator could have managed.
I bought a Interdynamics HD300 about 15 years ago, works like new and still going strong. Best portable 12volt compressor Ive ever owned. Will inflate a fully deflated 16" tire in about 5-8 minutes...(if memory serves me right)
The only weak point is the 12 connector, but it can be easily upgraded. It states it can run for "8 hours straight" but I seriously doubt it. Made in the USA and I don't think they make these anymore. I could be wrong..
Thank you all for excellent input. Have a "retired" 73 Monte Carlo who sleeps in the garage and needs his tires inflated every few months. Will be looking into your alternate suggestions. Yours are the type of comments I really use and appreciate. Thank you! :)
For cycling there's CO2 inflators that are smaller/lighter. Better portability. For the garage use I use the dealt DCC020IB inflator. It can run for 20 minutes then needs to cool down. But it will top-off 4 tires (down a few PSI) in about 1 minute each. More time if much lower. Of course, more money $80 plus a battery) but it will do air mattresses and floaties too. For auto portability there's stronger options out there. Some of them plug into car starters so are more portable and versatile.
This seems cool, but not sure what uses it's good for.

The 73 MC are awesome. Make sure you drive a bit to avoid flat spots.
I have a couple of those Ryobi drill-like hand-held compressors and they've worked great for the family's 4 vehicles.
The previous version (non-digital gauge) was often on sale for $20 (without the battery & charger).
