AUTDER Tire Inflator Air Compressor,21V Battery Powered Tire Pump,180PSI Pistol-shaped Handheld Air Pump with Digital Pressure Gauge, Automatically Shut Off, Perfectly for Cars, Motorcycles, Bike

I've had this for over a year using it to inflate bike tires up to 110psi. I have a big 60 gallon 2 stage compressor in the garage but I wanted something I could also toss in the back of a car or grab and use real quick.The unit works great with the ability to set a pressure that it will pump up to then shut off automatically. It's worked great all summer and the battery last long time. Granted these are bike tires so they are low volume compared to a full size passenger vehicle.Two weeks ago the battery died unexpectedly and I reached out to Autder via email explaining the failure and despite my unit being outside the warranty period they sent me a new battery no questions asked. I was not optimistic at first and thought I was going to have to buy a new inflator, but they sent me a new battery and got me back up in 3 days. Also what I really appreciate is the fact that they just took care of my problem without asking me to write any reviews or anything.So I can attest that they stand behind their products without making you jump through any hoops and hurdles.

I researched all the different types and brands and prices. This one seemed like the best choice for me. It came with a nice case to keep everything together. I like the way you rotate a wheel on side to adjust pressure setting. I charged it up fully when I took out of box. It filled 3 truck bigger tires from around 25 psi to 50 psi before it ran out of power. I thought that was pretty darn good,considering the size of tires and the ease of use. Of course using an air compressor is faster but it’s also a pain in the butt when you get in your car in morning and it’s below zero outside and you have that one tire that went low overnight bc of temperature change. So this year I said I’ve had enough. This tool is going to save me so much time and hassle. Now I can just grab one tool from trunk where I’m going to keep mine or maybe even backseat hook it up press one button and walk away. No more running hose out and trying to mess around.I love it! I used for mower, motorcycle and I bought a second one for a gift. Very handy very happy with purchase. I think every one should have this tool right next to a good jump box in their garage inventory.

I bought this pump in October 2022. I used it may be 5 times or less. It worked well on cars ok but whenever I took my car for service they always say no t is over inflated although I just pump it till it is 35psi per the car manual but somehow the meter on this pump is not accurate. It never worked on bicycles. It just doesn’t work. Today I tried to inflate one of my car tires, the engine works but it doesn’t get any air in the tire.I am changing my review because of the excellent support and customer service. The issue was in the last inflating cable, it would not latch on a schrader valve because the plastic lining was gone. Support sent me a replacement cable in two days and someone also offered to send a new unit.The engine is powerful and it takes seconds to inflate my bike. The only issues are that it heats really quickly and the latch at the end of the inflation cable can break after few usages.

It worked well for almost a year. The battery went bad and now it's useless.

Purchased this to put in car in case my tires needed air because everytime I tried to air tires at a station, machine was broken. This wireless portable inflator is great because you can set the desired ppi and fill, no need for a separate tire guage. Customer service is super! I had a defect in the hose, contacted them and they promptly sent me a new hose.

I've bought two of these pumps just for ease of use very happy with them the battery on the other hand is useless it lasted about a week and now it's not only dead but won't take a charge and this happened on both of my units that I have purchased the only way the gun will work now is if I plug the power into the handle the battery is totally useless and I can't find anything else that will fit so be sure that you're within 12 volt power supply to use this compressor

Overall the unit worked great. Pumped air quickly and had a nice battery charge to it. The pump gets very hot when used frequently, but the biggest problem is the quality of the tube. After using it 12 times the tube split open and was no longer usable.

The fill-till-full option for this pump is great. You set (either by choosing the vehicle type or direct entry) the PSI you want your tires at and pull the trigger. The pump fills the tire to that pressure and stops. There's no indecision as to the pressure, either. It runs until the tire is full and stops. The pump comes with a rechargeable battery, which is convenient, but it wouldn't last long enough to fill 4 tires from 28 psi to 36 psi. Since most people will leave this pump in their trunks for months/years on end and forget they have it, the battery won't be worth crap after a while but it's a nice thing to have. The pump comes with a wall charger and a 12v cigarette connection, so you'll always be able to run it on the side of the road. Overall, I liked the design.
