Inflated 3 of my truck tires with no problem, stopped when reached the desired psi. The 4th tire was 1.5 lbs. over and wouldn't start the compressor. Really impressed with the unit. Didn't use the battery jump start yet but sure that it will be good. C.T.

Ok product, the power on the air compressor is a little week and it would not jump start my F250 truck because it lacked the cranking amps. The jumper cables are shorter than they could be and the hose for the compressor is difficult to return to the storage compartment.

Easy to use, self explanatory, easy to charge, the you can pre-set the air pump settings to your tire pressure and it remembers the pressure settings. The battery last a long time, use can check the battery strength with one button. All the functions can be seen one screen. I am recommending this unit.

Purchased 2 weeks needed air compressor, worked great, liked auto shut off at set pressure. Work light is bright Have not needed other features but charged and ready to go. Side note, instead of 4 usb's, 2 usb's and one 110 volt outlet would cover all situations..

I purchased one last year for myself and loved it so much, I bought another for my brother for his birthday. It definitely came in handy on more than one occasion. The air pump alone is worth the price; let alone the battery charger and alternator tester. Definitely recommend. I love the fact that you can see the PSI.

This device is great. When ever my tires need air I can inflate them my self. I have lone it to others to boost their car batteries. One charge of this device and it last for months without a recharge. I bought one for myself years ago. It has done everything it was designed to do. This new one was for my daughter.

Could have been 5 stars, if they had kept them in stock in some of the local stores. After many trips, finally decided to try shipping… it worked! I got 4 of them, all arrived in good condition and charged. Biggest problem was I got 2 at the instant savings price of $59.99, BUT 2 came at $79.99, the regular price, and I couldn’t get the right price no matter what I tried! So BEWARE!

I took this out of the box, read the directions a then charged it. When I took it off thew charge I pumped up my car tire that was four pounds lite and it stopped on the setting that I had put on it and it only took a few seconds. It is a great unit, and I am happy that Sam's had it to sell.

Have only used once. Had a good amount of power while jump starting my 98 Chevy pickup. Battery was drained due to sub zero temps. Lasted thru 4 or 5 attempts to start before running down. I was impressed it lasted as long as it did before recharging. Only complaint is that you have to have a separate extension cord to plug it in to recharge it. Which means if you travel with it you need to carry an extension cord with you as well to recharge.

This unit has gotten me out of a jam on a few occasions. The compressor works great and even has a feature where you can set the desired pressure and start the compressor and it will shut off when it reaches the set pressure. Now the downside. The box is roughly over a year old and it seems the battery is getting weak. I have tried to use it recently to jump off a ram 1500 and it didn't have enough power. The unit showed full charge before I started and instantly went all the way down to low battery after the first try. I like the product just feel it could use some improvements. Would be awesome to see a version that can be operated off of a drill battery. Also not much info can be found online about the tool.
