1400 Peak Amp Jump Starter with Digital Compressor is rated 4.3 out of 5 by 238 .

Rated 5 out of 5 by thedogscar from Overkill for Emergencies This is one heavy (35lbs) duty device! It has 700 starting Amps and 1400 peak Amps. More than enough to start a V8 with a cold engine. It has an alternator tester; which lets you know if it is your battery or alternator that is faulty. It has an air compressor that goes up to 120 PSI. The hose tucks neatly inside and has a screw-on tip; which is nicer than the push on tips, that push the valve into the rim when flat. Set the pressure you want, and it shuts off when reached. It has 2 USB ports, that are 5V each, with 3.1A combined output. It has a 6 LED flood light, on the back side, which is pretty bright. It has more power, pressure, and USB's than you would need in most emergencies. The light is the only thing not overkill. It would be nice if it had a low (if you need to have it on a long time), high, and flash (if your car does not start with this, you will be there a while, and flashing light will make sure you are not tail ended while waiting).

Rated 1 out of 5 by Peeohd from Should be called junk box Bought 5 months ago replaced twice and now Home Depot nor manufacturer (black and decker for dewalt) won’t honor warranty. Each time it died during compressor or jump use. I’m no novice and I did not misuse this in any way Stay away. Search for online reviews and you will see for yourself.

I have jumped an 8 cylinder SUV with this without any issue. I love how the unit tells you when to start the car. We have also used it at work to inflate several vehicle tires and charge equipment via ubs ports.
