Says it will work on a smaller V8 jot so much. Fully charged it started once with starter clicking, then finally turned over. Would not start engine a second time. Not sure how it would work with a smaller engine. Have not tried other features.

I love this product. This has fixed numerous flat tires and charged several batteries. My only complaint is that some of the indicators do not make sense. Overall, a great product.

Worked good for about one year. Two years later air compressor no longer works. Crank pin keeps falling out. Does not hold full charge. No manual on line.

Stopped charging after a few months. Worked great until I couldn't get it to charge anymore. They said I could send it back to have it repaired, but with the weight of this thing the postage would cost more than just replacing it.

Stopped inflating my tires. It reads the tire pressure, but when I press the Compressor button, it won't inflate to the setting I selected, and instead shuts off after less than a second.

It worked fine when I first bought it, took it out to charge it two days ago, nothing on the unit will turn on, the light where the battery status has stayed on since I plugged it in and is emitting a high pitched whine and won’t turn off

I bought 7 of these power boosters and already garbage 4 of them, 2 left one just stopped charging and the last one kerp turning g on light and not charging more than 25 percent.

Battery jumper portion of the product is good. I bought this product for the tire pump feature. It has a setting for desired air pressure. The problem is the gear that drives the piston breaks leaving you with an expensive battery jumper.

I’ve had this product for a little over a year and use the air compressor a half dozen times and now it just doesn’t work no more it turns on but doesn’t air nothing up the jumpers still work though.

I haven't used the compressor, so no comment on that. Bought it to jump start a lawnmower. Won't even do that, but when I use jumper cables from another mower it starts up. It's a piece of junk - don't buy it!
