After reading a lot of mixed reviews I felt I should add some more info so people can make an educated decision. We did not buy this unit from amazon but from a big box store. We have had this pump for about two years now give or take and so far so good. If you are looking for insane capacity, speed and power keep moving for something else. I have a 28 ACFM compressor for air tools, grinders, air arching etc. It is a pain for my wife to start it up and hook everything up just to inflate a bike tire or pool float for the kids. So we purchased the Slime all purpose pump. It works well and seems to last quite a while on the battery. This unit can also operate on the 12 volt power plug included. It will not operate while plugged into house power. I can adjust tire pressures on my Silverado (33X12.5 Tires) and Expedition (33X12.5 tires) several times without the unit needing a charge. It does inflate bike tires with ease as well. I would say that it takes about 7 to 10 minutes to inflate all 4 truck tires from 35 psi to 50 PSI. Bike tires are pretty quick, under a minute.

The controls are not as complicated as others may lead you to believe. I can also see why they are designed is way which seems to be avoiding accidental power ups. To operate you hit the set button to wake the unit and then use the up or down arrow to adjust your target tire pressure. Once you select your desired pressure, say 50, 60, 80 whatever PSI you simply hit the tire button and away the unit inflates to the desired pressure. The only downfall I have with this unit is the internal gauge is off by 2 PSI which means I just command 2 more PSI over what I want, IE 45 PSI I set the desired pressure to 47 PSI.

I would say this is a great compressor for the average home and pool owner, it's easy to inflate rafts and floats poolside or bring it to the beach to inflate your tires once you are leaving. I have zero complaints with this as it does exactly what it's intended to.

This has a lot of neat features like auto shutoff at the desired pressure, but it isn't well designed or well made in my opinion.

1. Tubes come out the back so you can't lay the unit down flat while pumping your tire. But you can't stand it up either because then you can't see the controls. The air hose attachment is very hard to twist onto your valve stem meaning if you try to fill a bike tire like I do your bike tire will be nearly flat before you get it attached. Then you pump up to the recommended pressure -- but when you remove the connector you lose a lot of air again! The air connectors other models use, that have a little flip handle to quickly attach and detach, work much better.

2. The controls are push buttons but they aren't "on-off" or even "push once for on push same button again for off". No, it is some complicated formula. You push some button once to sorta wake the machine up. Then you set the desired pressure. Then you push the same button again to shut it off. Then a third time to start pumping. Maybe. Or maybe not. Just keep punching buttons.

3. As if the buttons weren't hard enough to figure out, they get stuck. So if you want to "push the on button to turn it off" you can't, because it is already pushed, and it won't push any farther.

4. Finally, the unit made an explosive rupturing sound while pumping my tire at 40 pounds (target was 45) and actually blew off part of its own plastic casing. I know this wasn't over the design limit because I've pumped my high pressure bike tires to 85 before, and the gauge goes to 100. Some flimsy plastic part deep inside had given out and now the pump hisses air like crazy and instead of filling the tire, it leaks out whatever air you already had. So, at this point, effectively dead. And good riddance, I say; I'm tired of its frustrations anyway.

The inflator is great, relatively quick not too loud and awesome being battery powered. I have the inflator in the boot of the car recharging and is extremely easy to use. Good clear digital readout and pressure setting with auto stop makes life really easy. The hoses and cables all store neatly away in back compartments and the unit is really neat.
The only part that I think needs a rethink is the screw on hose connector. The screw fitting onto the tyre valve is rather fiddly and slow and it is very hard not to lose air when screwing the hose on or off the tyre valve. The screw fitting is definitely better for setting and leaving but certainly needs improvement, apart from that an awesome little inflator and very happy with the purchase.

I bought this tire inflator for my wheelchair tires, which need to be inflated to 145 PSI (yes, I'm serious. 145. They are performance tires)

There is no indicator of the max PSI rating on the box of this device in any way, at all. I assumed like most of Slime's other inflators/compressors that were similarly priced that it would be able to go to 150psi.

Unfortunately, it only goes to 100 psi.

Otherwise, it seems like a solidly built unit and comes with many accessories to inflate a variety of inflatables, and I really liked the digital gauge that shuts off when you reach whatever PSI you set it at. I also like that all of the bits can be packed into the unit, so you can keep it in your car without losing them.

I would love this unit if it went up to 150psi, but I had to return it because it does not meet my needs.

Slime really should put on the box that this does a max of 100psi.
