AstroAI Jump Starter with Air Compressor, 4000A & 150PSI Portable Car Battery Jump Starter (10.0 Gas/8.0L Diesel) with Tire Inflator, 12V Battery Charger, 18W Quick Charge, Jumper Cables, Lights

The air compressor was impressive. My car tire was down. It inflated the tire from 12psi to 36psi in under 5 minutes. Probably closer to 3 minutes. I have not used it to jump a car, but I think I'm going to like it. It is well worth the cost to have in your car for emergencies...

Charges great. It has a boost button if your battery is too low. One boost and car starts right up. It will also air up tires and charge your phone. Highly recommend.

Takes less than a second to start your vehicle. No waiting for the battery to charge like you work for AAA; no engine cranking because the charge is instaneous. The only time it didn't work was when I attached the leads to the opposite colored battery poles. As soon as I switched the leads to red on red and black on black, the lithium ion starter worked as usual with no harm done. This jump starter turns itself on automatically when you insert the wires to the lead clamps into the compact body of AstroAI. If you see the green light, your vehicle will start.

A JUMP VEHICLE THAT HAS BEEN STORED FOR MONTHS INSTANTLY WITH BATTERY COMPLETELY DEAD..ALSO TAP OFF ALL TIRES WITH AROUND 10PSI EACH. STILL HAD HALF BATTERY TO USE FROM BEING FULLY CHARGED. IT'S POWERFUL %26 IS A GREAT UNIT. PEACEFUL MIND WHEN TRAVELING.

This is great to have in an emergency. Holds a charge well. Great for power failures or to quick start your car, etc. I'm so glad we got this!

My husband's friend show him one a d we immediately brought us one. I've used it 3 times on my tires, work dolly tires and my neighbor used it. We decided to buy more as gifts for Christmas.

I have yet to use the jumpstart function. However , the compressor works great. Only had to top off low tires so far. It is very easy to use and charges quickly. Only time will tell.

love everything about this. it's easy, convenient and takes up little room in my vehicle. would definitely recommend. oh and just bought one for the moterbike.

Excellent. small and mighty.

Its great over all but takes forever to charge and runs out fast. Everything else, perfect. Definitely worth the money.
