YANTU Cordless Tire Inflator Portable Air Compressor Air Pump For Car Tires,Tire Pump Battery Powered, Dual Cylinder 2X Inflation,tire pressure gauge with 8.3Inch Digital Screen for bicycle/Pickup/SUV

I liked the simplicity of it and the accuracy of the PSI gage. My tyer gage light came on in my car TIRE LOW! Most likely seasonal low reading from warm to cold weather can do this. The pressure dropped, so I used this for the first time, and it worked like a charm. it read my PSI at 30.5 and I set it to 32. psi and took 30 sec or less for each tire. I did all for safe keeping because what the heck while I'm at it why not. simple to stow it back away for another time, it's compact so i placed next to my spare tyre under the back hatch out of site.It was clean efficient and neat looking case.

So far it's only been used once to top off 4 performance all season tires on a new Civic but the speed at which it added 5 PSI was surprising and auto shutoff was spot on after checking them after with a separate gauge. The sound the pump made was smooth and quiet and nothing like some older units I have used. I can't say much for battery life as it's runtime total was about 30 seconds but we will see.My next test will be to top off 4 high speed rated summer tires under quite a bit of weight on a Tesla and I will update if the experience is different.3 Month Update: I still love this thing. It's been great for keeping my tires topped up just right and is much faster than I anticipated. The battery life is downright amazing so far. I do notice that it warms up a good amount (mostly at the air hose attachment point) with ambient temps outside above 90 and would probably be a bit hard on it if I pushed it much.

This is a marvelous product. It is light weight and easy to use. I was pleased to see that it could inflate all four tires of my car in a matter of minutes, without a noticeable depletion of the charge of its battery.Its accuracy is spot on. Simply set the pressure you want in your tires and press start. When the set pressure is reached, the unit automatically stops. ... Beautiful!The unit can be fully charged in only a few hours.

This thing is a piece of crap. After inflating a low tire for 5 min. it stopped. Started it back up again and again and it con't for 5 seconds before stopping again. Made in China says it all. Looking for American made.

I love this and the fact that it’s portable is even more of a plus. The only downfall I would say is, the battery dies quickly. When I’m using it to pump air, I have to keep the charger on in my car so it won’t turn off in the middle of me pumping air.

The wireless car tire pump is a must have for emergencies and for freedom to keep tire pressures at safe levels and to make your tires last longer without having to take the time to find a place to pump up. NO MORE HASSLE! It pumps up tire quickly and not nearly as loud as other pumps I have used. It is portable so that you can take it anywhere your car goes. No need to find a gas station or somewhere else to pump up your tires. Just take out your Yantu, attach hose to unit and your tire and leave it on the ground (it uses the better wing metal connectors instead of the cheap plastic ones). Push button to turn on. Set pressure level to pump up to your desired pressure level. Push play button, and it will automatically pump up to preset pressure and then stop all by itself. IT DOESNT GET ANY EASIER!Comes with everything you need including carrying case. Also pumps up balls, bicycles, and more. HAS A DOUBLE CYLINDER INSIDE THE UNIT TO MAKE MORE AIR AVAILABLE TO PUMP UP FASTER THAN THE COMPETITION! Paying a little more is worth it for this unit. I am very pleased with it.

You are not going to get any kind of instructions as to how to use the item. I have not used the item as of yet because I don’t have any kind of instructions. Okay I found the instructions but I will not say anything about it at this time because I haven’t used it.

I love that it’s compact but strong, I have a truck and it filled my tires up in no time. I set it for 45psi and according to the gage on the dash it’s spot on. I’m giving it a full charge now and we will see how it stands up to summer temps. Not sure if it has a drained battery, if you use the cigarette lighter in the car, it will still work. I’d imagine it can but I haven’t tried yet. I will be doing an update in the future but as of now…. It’s great!(((Update))) I just used the unit to fill my tires after stowing it for a couple months under my seat with a full charge. After all this time the unit showed 3 bars charged. I believe that still is a full charge. I filled each tire on my truck With a couple pounds of air each. The unit showed 1 bar when I was finished. This is battery only you still could fill with the cigarette cord if needed. I set the machine at 45psi and it was dead nuts on according to the dash readout in the truck. It is a good little compressor until especially if you’re in an emergency.
