KeenPower Tire Inflator Portable Air Compressor - 2X Faster - 21V Rechargeable Battery Powered Handheld 160PSI Tire Inflator, Dual Power Supply Modes, Air Pump for Car Motorcycle E-Bike

This inflator is totally awesome! Took about 3 hours to fully charge. The screen shows pictures of all inflatable products, car, bicycle, sport items, set the needed PSI and it automatically stops. Wireless and good voltage and great price! I already had a cordless inflator but couldn't find it so I needed one quick so I went onto Amazon and got it overnight! Sometimes things happen for a reason and I am glad I couldn't find the inflator I had because this inflator is so much better and you get a cool zipper bag for storage. GOOD BUY!

This little compressor packs a punch! I’ve used it on car tires, bike tires, and even sports balls — and it inflates everything quickly and accurately. The digital gauge is easy to read, and I love that it shuts off automatically when it hits the set pressure. It’s compact but solid, and the battery charges fast. Great to keep in the car or RV for emergencies or road trips. Total peace of mind!

This works better than I expected. Comes with a nice case that is easy to store in car. Battery charge last. Easy to read and accurate.

It works great product Why did you pick this product vs others?:Convenient

Easy to use. Light weight, inflates quickly

I have owned a few portable air pumps and so far this is the only one that has an accurate gauge. Most of the other units that I have had or as far as 3 to 4 pounds of pressure low so it inflating my car tires to 36 pounds. My car would show the tires were inflated to 40. The auto shut off feature is very nice to ensure that the tire is not overinflated and the portability of this unit is great and allows me to bring the compressor to the car and not having to use my large compressor just to fill a car tire or bicycle. The build quality looks to be durable and very compatible too the brand name portable air pump. The other area that I was pretty impressed with was the fill rate this unit seems to air my tire up any much faster rate than any of the other ones that I have had and the battery so far has been quite impressive at hell long it does last the last portable air pump that I had would be almost completely exhausted after just going around and topping off the tires on my car. When I receive this unit, first thing I did was charge the battery to make sure that it was fully charged, which is what you should do even though it does come with a charge in it. It is always best to top it off before the first use to ensure maximum battery life. Once the unit was fully charged, I took it around to all my cars and trucks to check all the tires and the battery did not run down at the same rate as the smaller portable unit that I have. The fact that this is a dual power unit that can be powered by the battery or plugged into the lighter of your car. Makes this a great emergency tool to have with you when you’re taking road trips for me I always take a portable compressor and a portable jumpstart pack when I am traveling just in case an emergency situation comes up or if I encounter someone who is having a problem, I am prepared to help. The only thing I wish that they would do would be to include a second battery not that it needs one, but it would be nice to always have a second battery fully charged as a back up. For the price of this unit compared to the price of the brand name, but this is designed after this is definitely one of the better buys that I have made. A lot of times they say you get what you pay for and in this case, I think you get a little more than what you pay for. As far as noise level, this unit is about typical or a small portable air compressor. It is by no means loud, but just like any other air compressor. There is going to be a certain level of noise associated with the air pump. If you were considering buying a portable battery powered pump in my opinion, this is one to buy. I stated earlier in the review when inflating my tires to 36 pounds and checking it against the car’s computer. The car reflected exactly the same pressure as the Phil Gage and my Auto shut off point which was quite impressive. Hopefully this will help someone in making a decision but yes, in my opinion this is a great solution for a battery powered pump and hopefully it will have longevity to the compressor and does not wear out as quickly as some of my others

I think this little compressor is fantastic! It fits in the case nicely and containe everything for sports balls, air matressesm and of course for your tires! My auto tires require 42 psi im all four tires. they goen down to 35, 37,37,38. So I figured the would be a good test. With a freshley charged battery I filled them all to 42.5 (you can it in .5 incriments starting at 35psi when vehicle is sellected). Each tire filled in a little less than 2 minutes. So about 8 min of run time. You can push a button on the removeable battery to see the abount of charge left from 1 to 5 lights (1 very low to 5 fully charged) I expected about 3 lighrts to show and was very plesenty surprised to 5, stlll fully charged.l think this thing is great! Buy it!!

It worked great for 3 tires psi 46 and then it got hot stopped working waited 15 minutes then filled 4 th tire then it got hot again for spare tire waited 15 minutes then filled the air at PSI
