GOOLOOAP150 PRO Tire Inflator Portable Air Compressor, Upgraded UI Color LED Screen & 4X Faster Car Tire Air Pump with Tire Pressure Gauge, 12V Electric Tire Pump with Auto Shut-off for Car,Bike,Ball

Its awesome, pumps quick and is not very big! The air hose does take two hands to install on the tire, so you have to set it down on the ground.

This is as great as advertised. Easy to use and came fully charged. We used it for car tires.

Easy to use. Only goes up to 50 psi.

So several reviews already focused on how well this pumps air and that it is a mediocre phone charger. This rechargeable air pump is a great value in my opinion and I just want to touch a few other things that maybe some reviewers missed. First, I didn’t like the bag. It’s a light grey felt which means it picks up dirt and everything else it gets around. And this being a tire pump means the bag is not always going to be in the cleanest places and mine already looks pretty nasty. That’s not a big deal, I didn’t get this pump for the bag. It’s just a nuisance. And I have no intention of using this for a phone charger. I got this to use as an air pump and I intend to use it ONLY for that purpose so I don’t care about that. I like the fact that it can cycle through different modes depending on what you are filling. To turn it on, press and hold the power button. To cycle through modes (like car tires or bike tires) simply press the circled arrows. To change between units (psi, bar or kpa) cycle through to the mode you want and then press and hold the cycle button until it beeps and the psi starts flashing then press it again to change it, then leave it alone and it will set. You can set a different unit for each mode. The modes are automobile, motorcycle, bicycle, ball (as in a basketball, soccer ball or football) and a custom setting which is just a person. And then you can set the upper limit with the plus and minus buttons. The number in the circle is the actual unit being read as the pump puts air into the tire so you can see it working and changing. It’s about as loud as most air pumps, can’t get around that and it does get hot. Overall, this is a great little air pump and I hope to have it in use for a long time.

The media could not be loaded. This will be the fifth portable inflator I’ve used, and it’s among the best. None of them are quiet but this one seems a little bit less noisy. It has a lot of good points and only a couple of weaknesses, so let’s get those out of the way. The power bank function is very, very basic. Only the bigger, USB-A connector is an output, and even then it’s only 5V and 8W. Functional, but modern phones will charge like it’s the year 2010. The USB-C port is input only, and again, very basic. The manual says it’ll charge at 10W but I measured it at 8W. That’s quite slow for such a big battery. I ran it down to about 25% doing testing and it took about 4 hours to recharge.Now to the good points! It’s very accurate and consistent. I completely deflated a 195/50R20 tire. To refill it to 15psi took just under two minutes (1:53) and the inflator stopped at 15.4psi as measured by a recently calibrated gauge. Here’s a table on time to reach pressure:PSI Time15 1:5320 2:3425 3:2030 4:1235 5:0640 6:0545 7:07At every 5psi I checked the actual pressure in the tire and found it about 0.6psi higher than the set point. That’s really quite good. I prefer it be a little over than under because it’s easier to bleed off air than connect the pump again, but this is so close that I’d just leave it. (At 48psi, where I run my tires the actual pressure was 48.8 as seen in the photo.)The inflator filled the one tire twice, then topped off the other three tires (adding about 4psi each) and still said it was at half charge. After running the test tire all the way up to 48psi, the base of the hose got to 100°C (212°F) which is why it has a warning sticker.The hose is not long enough to reach from the ground to the stem on a 20 inch tire if it’s at the top, but the unit hung from its hose with no issues whatsoever. I actually preferred that to laying the inflator on the ground. It rattled and moved around until I put a cloth under it. Even though the hose isn’t long, it does use the same thread as a tire stem so you could put two or more hoses together if you have them.Of the pumps I have tested, this one is my favorite.

My husband was skeptical and thought this was a joke. Joke’s on him because this little inflator is amazing. We had a tire on our Wrangler that was low and our local gas station air wasn’t working. Once this inflator was charged we tried it out and quickly realized how much we needed this in our lives. My husband set the psi and once it reaches that level, it turned off automatically. The tire stayed inflated and I’ve had zero issues. This inflator is definitely a must. I’d like one for my oldest son’s emergency car kit. It’s super easy to use and can be used on various items from toys to vehicle tires. It’s small and worth the money to add to your car kit.
