OAK&IRON Battery Tire Inflator 2X Faster Inflation Portable Air Compressor 150PSI Cordless Tire Pump with LED Screen for Cars, Bikes, Motorcycles, and Balls

I ordered this and received the product on Jan 18, 2022. Followed all the instructions, but it appeared to not fully charge up, as Id get 3 out of 4 full bar indicators, but the 4th would flash continuously regardless of charge time. Several days later I tried to fully charge again, with the same effect. Id get 3 out of 4 full bar indicators, but the 4th would flash continuously regardless of charge time. A few days later it still held a 3 bar charge. I decided to go ahead and use the product to fully inflate 8 different sized bicycle tires, and was pleased with the performance of the product. The product wasn’t as loud as expected. I allowed some cooldown time between inflations. The inflation time was fast enough for me to be happy with it. After 8 tires, the product indicated 2 full charge bars out of 4. I again tried to fully charge the product with the same results as the prior tries. After sitting for a little over a week, I went to use the product to inflate a car tire that was indicating low pressure, and the battery was completely dead. This was more than seven, but less than ten days from the last “best I could get” full charge. Battery does not perform at anywhere near the advertised capacity for holding a charge, and will not fully charge. I am 6 days past the 30 day return policy, but will be requesting a replacement or a refund. Update: Customer service responded within 24 hours of this post. They were very helpful and are sending a replacement for the product. Updated rating from 1 star to 4 stars for now. Once the replacement is received, I will further update this review.

This tire inflator checks the boxes for my needs. It has a wide range of pressures supported. It is easy to operate and the display is easy to understand. Would definitely be a 5 star if the battery lasted a little longer. Manufacturer states should be able to inflate 4 automobile tires to 35 lbs on a single charge. I was only able to get 4 RV tires from 45 to 55 lbs on a single charge. Otherwise a great product.

I think everyone should have one of these in their cars. I cant twlll you how many times it came in handy in the short time Ive even had it. I also like that in case of emergencies you can use it as a flashlight and a portable charger. Its also fills up my tires much faster than a well known name brand comparable item.

Great pump!! So well made and quiet too. And easy to use and the numbers are big and bright. Very happy and impressed with this!

I carry this with me in the toolkit for my new bike. It came in very handy when I had my first flat. Its not clear, but it would be nice if the USB-C port could be used to charge a phone.

Were having single digit temps which means we need to air up all. the. tires. For some reason in this town all the gas station air pumps are broken/out of service. Enter this tire inflator! Took it out of the box, screwed in the hose. Turned it on. Set it for auto. Arrowed to set it to 32 psi for my tire. Put it on the valve stem, pressed pump. It ran, watched the current pressure rise. It turned off when it reached 32 psi. How EASY is that!? When I got it, the battery was about half full. I took it out of the box and got 6 tires done before it shut off. Not bad, totally expected it to die because I hadnt charged it. It has charged overnight now, and I can go out and air up the rest of the tires. No more battling gas station air machines, no more dragging cords around the car. Everybody needs one of these!

Nice little inflator …. A little slow filling a tire but it is compact and will get the air pressure there!

I was so impressed by what all this little guy can actually do and the battery power it holds and totally made my hubbies bday, because his car tire always leaks plus we are huge bikers(road and mountain ) and great for that and so much more!

Worked well, just wish the battery lasted longer!

This product is a must for anyone who hates going to a gas station to fill up the tires with air. It is so easy to use and its extremely accurate. I had my doubts before the product arrived and those doubts were thrown completely out the window. I even tested the pressure in my tires after inflating them with a tire gauge, and the pressure was spot on. I give this product my highest recommendation.
