- GT150 Tire Inflator Portable Air Compressor，4X Faster 150PSI Cordless Air Pump for Car Tires with Tire Pressure Gauge, Smart Electic Tire Pump with Auto-Shutoff for Pickup, Motor, Bike，Balls

For something small it does its job well. I have used it to add air to the tires on both my Tundra (30 psi) and F-250 (65 psi). It is easy to use. You can set it to inflate to the designated psi. I used it to add 10 psi to each of my F250 tires and it did it on one charge. I also took a large tire on my Tundra and filled it completely on one charge. As with all compressors, if you are doing multiple long fill ups it will get hot. This is not meant to take multiple tires from zero to recommended psi. It will completely fill one tire well or bring up pressures on 4 tires that may have been low due to seasonal changes.

I think something like this is a must have for long trips. I got this so I could have an easy-to-use air pump for my truck. I have the ones that you plug into the truck power port, but those are not very convenient. I have the GooLoo jump starter which has worked great in the past when needed, so I wanted to get their air pump. I am impressed with how well this works and how quiet it is compared to other smaller pumps I have used. This is definitely a quality item. This is also much quieter than any other small pump I have used in the past for filling tires. I also like that you can set the desired pressure and leave it alone as it will shut off when the pressure is reached. The only issue I ran into was when I was filling my truck tire which was 10 pounds of pressure low. I hooked it up and it ran perfectly. I did notice that the air hose was getting hot, as I have seen with other pumps in the past. Then suddenly, the unit shut off before reaching the desired pressure. Evidently there is a safety heat feature that protects the unit from overheating. While this is a good thing, I was only able to do that one tire. I then had to wait for about 15 minutes before I could check and fill the other tires which did not need as much air. The advertisement says it can fill 4 car tires. It can probably due that easily on one charge, but the heat safety feature will prevent you from doing that all at once. Not a bad thing, but something to know.

This inflator is so handy and so accurate. Just set the desired pressure, and it will shut off at the perfect pressure. Best for touching up tire pressure rather than fully inflating a complete set of vehicle tires. But it also works great on smaller tires and such as lawn tractors, rototillers, wheelbarrows, etc. Also great for volleyballs, footballs, basketballs, etc. All around, very handy.

Perfect for tire inflation. Need better, larger adaptors for inflatables, like air mattress, etc. Overall good product.

So far, after a few uses, seems to work well. The battery doesn't last very long, but it'll work for topping off 4 to 8 tires or pretty much inflating one or two from scratch. Very compact package. Compared to traditional inflators, it's very nice to be able to set the desired pressure and walk away. It's not fast, but not having to monitor it makes up for the speed.

I have used this to inflate a total of 9 tires/air tanks so far. The highest pressure I’ve gone to is 40 psi for my car tires, which it has been able to do alright. It does have a warning that it gets hot when running for a while and it does, but I only use this outside anyway and it is quite cold and the heat can dissipate well. I hope it runs for a long time because it is very handy and saves me a trip to a gas station, which may or may not have access to the air pump depending on the weather. I store it inside the house and not in my car because I don’t know how well it would store in the outside frigid cold. It’s loud, hot, and it takes several minutes to reach 40 psi, but it gets the job done and I will be happy if it continues working for a long time. On a full charge it can take two tires from 20 to 40 psi, maybe three if you’re lucky. Hopefully you never need to inflate more than that at any given time, and I haven’t so it fits my needs as is.

This air compressor exceeded my expectations... as you can see in the photos, it looks used because I waited until I had actually put it to work before reviewing it. It’s ideal for trips since it features a built-in battery, and the compressor is powerful despite its compact size. It comes with various adapters of different sizes, making it suitable for use on cars, motorcycles, bicycles, sports balls, and more—we even used it to inflate my son's raft when we went to the beach! 🤭... All in all, I’m absolutely delighted with my purchase; now I can head out on my motorcycle without a worry... plus, it turned out to be an incredible help by saving me from having to lug around an already-inflated raft and beach balls—all while trying to keep up with a little whirlwind of a toddler (my baby)! 😅

Love this tire inflator! Light and powerful. Auto shut-off when reaching the desired air pressure is a great feature. Seems very accurate as it is only 0.9 pounds difference from my other digital tire pressure gauge. Well built. I would buy again.
