Portable Air Compressor Tire Inflator for Car Tires, Beaspire Car Tire Air Pump for Inflatables with Gauge 3000mAh 12V AC DC Lithium Battery 150PSI for Car Bicycle Tires and Other Inflatables

UPDATE-Do not purchase from this seller. Seller sent me an email making excuses on why the pump can’t successfully inflate my tires 5 psi on one battery charge. Seller also stated the pump is not recommended for car or truck tires when the description states multipurpose “perfect for cars, bikes, motorcycles, RV, SUV, ATV, truck, sports equipment and inflatables adaptors.” I have screenshot the description as proof and will report seller to the BBB. Seller clearly doesn’t stand behind the inferior product they sell.UPDATE- I am even less impressed by this after using it a second time to top off my SUV tires due to temps dropping 18 degrees and my tires losing 1-2 psi (which is normal).I had to charge this device THREE times to top off a total of 8 psi, WTF?! Don’t buy this junk unless you want to spend an hour filling up barely there air.Not impressed! I needed to add 5 psi to each of my SUV’s tires and the device’s battery died after 2 tires for a total use of 10 psi. Had I had a flat tire 10 psi wouldn’t be enough as my tire pressure needs to be 37 psi. I would have to charge this device almost 4 times to fill a full tire?! So now I’m charging it so I can top off my other 2 tires. Then I’ll have to charge it again so it has a charge. I bought this for the convenience of not going to the gas station and for emergency use, but it’s mediocre performance isn’t reliable. By the way, the set psi is off by 1-2 pounds (it was off 1 pound in one tire and 2 pounds in the other) as I used a manual tire gauge afterwards to check.

Product description says 3000mAh battery for "2019 UPGRADED", but the version I received was still only 1000mAh. I only tested it briefly, before storing it in the car for emergencies, but everything seemed to work as advertised. The rate of inflation was on the slow side, though that was expected running off a battery. Not sure if that'll become an issue when inflating a real flat.

It is compact in size. Comes with a storage bag to keep everything together. The Battery can be separated from the pump and used to charge a smart phone. Clear instructions. Very pleased.

Used on a new sedan for 32 psi. It seems good for a half pound or sometimes one pound of pressure. Then it seem to just run and get hot. It has a few buttons and displays but the system is not easy to understand or responsive.

user manual is poor.It was not easy to know how to use sub tube needle

Good thing about it:Very small, easy to carry & store.Charge using Micro USB, as opposed to proprietary cable.Not so good:On a full charge, it couldn't finish inflating four car tires (from 30 psi to 35 psi), battery totally exhausted after halfway through the last one.The user manual is not the easiest one to understand.Very slow inflating.I saw some confusions regarding the claimed 3000 mAh capacity, as the battery cover clearly mentioned 1000 mAh! My guess is that it has three 1000 mAh batteries connected in series inside, hence 1000 mAh x 3 = 3000 mAh.Also the cover says input 12.6V, which is wrong, as the Micro USB charge port can only supply 5V, it probably means to say total battery output voltage, oh well.

Item arrive on time, item appeared to be well built but was unable to charge the battery even when on charge for over 12 hours, the instructions said should only take 70 minutes. Light and display would work when plugged in but went blank when removed from charging. Returned to Amazon for refund

Works fine so far. Some users are confused about the advertised battery capacity. It's common to specify the capacity in mAh for the single cell batteries like in your phone (4.2V). This device has 3 cell battery connected in series to provide 3x4.2=12.6V. You can either specify the capacity as 1000mAh@12.6V or as 3000mAh@4.2V. That would be the same number if you convert it to W*h which is a more appropriate unit.
