OlarHike Cordless Tire Inflator Portable Air Compressor, 150PSI Dual Power, 5400mAh & 12V DC Auto Air Pump for Car Tires, Motorcycle, Bicycle, Electric Pump with LED Light & Digital Pressure Gauge

Meets expectations. Worked well for me, so I bought a second one as a gift for a friend. Much better than turning on the compressor, moving car into driveway. Stretching out air hose. Filling tire. Putting hose back..Moving car . Turn off compressor. Or, even worse, having to fill tire at gas station. With this thing, can fill slow leak tire at the curb instead.

I NEVER ever leave product reviews right after I get it, as I wait to make sure it works great, or not, before writing something I regret. Considering that this item is not something I hope to need often, I am so impressed I decided I'm going to write now. I have wanted one of these type portable tire air-compressors forever but never trusted they could work that good, and, never really needed one for more than one or two low tires at a time. Also, at 75 years old I hate kneeling down at the air pump at a gas station (that I waited in line to get to) and holding the line and tire gauge until it's the correct pressure. Well, the last few years we've taken extended vacations of six or so weeks at a time so all 8 tires on my two cars are always low when we get back home. One car gets 30 pounds each and the other 38. All were 3-5 pounds down this morning when I went out to fill them after charging the unit yesterday (it was almost charged when it arrived and didn't take long). I went out with a rubber seat cushion for my knees and set the desired pressure, hooked it up and pressed the on button, with the unit also on the cushion. It was so nice standing, never needed to kneel other than attaching the hose to the tire valve, and watching the tire pressure go up and then turning itself off a minute or two later at the desired pressure. Here's what I loved. I was done with all 8 tires in no time, the unit never even got warm, and the battery level only went down one notch, so I'm sure it would've lasted for another 8 tires that just needed a good topping off.

This tire inflator works extremely well and is very easy to use. I love that I can set the PSI I want, and it automatically shuts off when it reaches that amount. No guessing, no overfilling — just simple and accurate. The battery power is strong enough to fill up my tires without any issues, and it finally got rid of that pesky low tire pressure light. It’s incredibly convenient having my own inflator instead of searching for an air pump somewhere. The build feels durable, the design is great, and it’s surprisingly compact. It doesn’t take up much space at all, especially with the included carrying bag. Everything fits neatly and is easy to store in my car. If you’re looking for a reliable, portable tire inflator that works exactly how you need it to, this is a great choice. Highly recommend!

I used this on the battery and not plugged in. It topped my tires off pretty quickly. The battery isn’t the best but you have the plug if needed. Overall it’s easy to use and works good.

After one day I really like this cordless air pump -- but see at the end for a "But"! It charges pretty fast: started out at 1 bar out of 4, and fully charged up to 4 bars in considerably less than an hour. I used it today on two cars/8 tires,m -- not heavy use, maybe 2 pounds per tire, and it finished pretty quickly for each tire and doing all 8 tires reduced the battery only to 3 bars of 4. It comes with a USB-C input for being charged, and has a USB output to let its battery charge other devices. I hooked it up to my phone to see if that would work, and yes my phone indeed started charging. Not sure if I'll ever use that, but it's a nice feature. The model I got also has an emergency light; again, it could come in handy, though I ordered this model for its battery capacity and not for that. It comes with a charging cable, USB to USB-C (which needs a charging block if you want to plug it into house current), also a 12 volt charging cable that plugs into a car cigarette lighter. I decided I like this pump and have ordered a charging block for it. If it continues to impress me I will probably order another one. Now here's the "But": check your package to make sure everything is in there. The first one of these I got was missing *the air hose that connects to the tire or ball or whatever*, which you obviously need to use it, as well as the replacement fuse. I contacted Amazon about this and they sent me another pump on condition that I return the first one. The replacement one had the air hose but *again* was missing the replacement fuse. I decided this is (hopefully) not a big deal so I'm keeping the second pump. I returned the previous one of course. (I'm hoping they send me the replacement fuse?)
