This product is great out of the box...after some shelf time... it's unreliable... don't count on it if it's been on the shelf for a while...not certain it's cost/value is worth it.... perhaps for diagnostics, but not when you are counting on it...as with all rechargable devices... it's important to let it completely drain before recharging, but then when this device is low...but not quite drained, you're stuck...

Too heavy, too cumbersome, designed with too many circuit parts and places for failure. Would not recommend to anyone. You have to maintained it charged every other month, cant leave in warm/hot places (eg. garage), can leave in cold places (eg. garage). Check YouTube to see the problems people have had and how they fix them, that will convince you not to buy.

I bought this power station a year ago. I have a classic car that sits in storage. One tire always loses pressure slowly. I've used this unit a dozen times to fill the tires and it's quite reliable. I was at a car club event recently and a buddy needed a jump start for his newer Bentley coupe. He said "we can try, but that little jump starter won't be strong enough". Low and behold, his Bentley fired right up saving him a call to AAA. I'm very pleased with how long this unit holds a charge (I keep it in my trunk) and how reliably it has performed. I recently bought a competitive unit to keep at home and it failed immediately (and the replacement was no better). I don't know what makes this particular Fatmax so reliable, but it seems to be cream of the crop at least for me!

They need to make the cables longer first of all, using it for a RAV4 2020 (terrible in itself), but it’ll work if used correctly. The reason for the one star is that it’ll turn on by itself every now and then- the battery tester will come on, or maybe it’s the compressor. The only way to turn off is to press the button- it’s like jammed but never been used.

I brought this unit from Sams Club just in case my wife or daughter had a dead battery or something. It always drains itself. It will not keep a charge. Its to expensive to ship to manufacturer. Its a big fat dud when you need it. And a total waste of money!!!!!

The first one I purchased from Sam's Club quickly developed problems with the control panel and returned after two months for refund. I decided to give it another shot later and it functioned fine for a year and half until recently when the motor sputtered and burned out after 10 seconds of putting air in a tire. Would not recommend.

I bought the unit about 3 weeks ago. I charged it for a couple days. The unit was not used until I needed to use the compressor to top off a couple tires. This immediately failed because the battery had already lost too much charge to adequately power the compressor. I subsequently charged the unit until fully charged and tried the compressor again.This time it very slowly added some air to a tire but after about 10 minutes the compressor started rattling and sounds like stripped gears. So the unit is trash.It will not keep a charge very long and the compressor would not build pressure in a timely manner ...I got it up to about 64 pounds pressure.

Had this for over a year. Compressor is a great have in the garage. The air pressure measurement always matches what the vehicle tire sensors state. Holds charge a good while. Fortunately only had to use it once or twice for the charge and jump, but worked well.

its heavy, loud when used to air up tires. The speed to add air to low tire was not as fast as I assumed it would be but was faster than other portable compressors. My teenage daughter was able to follow directions to jump start her car without assistance so it is easy to operate with clear directions on the unit.

I bought 2 of these, one to replace the factory compressor that came with my car and one for my daughter's van. Literally days after receiving it, she had to jump start her van which inexplicably went dead and the very next day had to add air in her tire. Having the screw on nozzle and being able to preset the air pressure allowed her to sit in the van and stay warm and safe until she heard it turn off. Plus she was able to use the built-in light so that she could see the tire nozzle allowing her to easily attach the hose. I haven't had to use mine yet, other than I did test out the usb ports by charging my cell phone. Those will come in handy for a power outage or for camping. I know having a wireless air compressor will be much nicer than the factory compressor with the power port cord.
