The area light tends to come on by itself for no explained reason. I have yet to contact the company, and will update this review if needed when I know more. If the battery can drain itself, if I was not able to see the unit, it would be worthless in an emergency.

This should be a one star review, but for some reason the app will only let me select two stars. The basics of all product expectations is that it reasonably does what it was made and advertized to do. This charger does not. The user interface (i.e. all the bottons you push to slect a function) is defectively designed in that the rubber buttons either dont work at all or get stuck, so that it won't work. The charging power output is unimpressive.

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.

Seriously? You you are left to track down a power cable that fits. Seriously Stanley? It would have cost you .50 to include a charging cable. If you are buying this to use for emergencies, OPEN IT FIRST AND FIND A CABLE THAT WORKS before you put it in a trunk etc! You don't want to be stuck thinking it is a self contained emergency product.

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've bought two of these. The first one quit holding and providing charges after the first year. The second one failed the 1st time I tried to use the compressor. I attached it and it make a big clunk sound inside (as if something disconnected) and it wasn't able to fill the tire. The compressor is totally shot. I'm done trying this model. Too bad since it has great features and if it worked as advertised and intended, it would have been great.

Purchased with high hopes but failed several times to jump start a 4cyl eng. compressor will only last for one tire then dies. Takes a long time for it to fully charge. And at exactly one year when the warranty expires it completely fails. Will not hold a charge.

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...

Stop charging after 3 months later, wasted money.

The air compressor failed after reinflating the tires on my 2 cars.
