Car Battery Jump Starter, 4000A Jump Starter Battery Pack (10.0L Gas/8.0L Diesel), 12V Jump Box Portable Car Jumper Starter with 70 Starts, 3 Modes Flashlight, Power Bank Funciton

I love this product. I am 78 years old and was worried about hooking up jumper cables. And couldn’t find anyone to help me when it was convenient for me. This is the safest easiest way to start a car. It started right away and I’m storing it in the car in case I ever need to use it again. Absolutely love this product.

I just used the air pump for the first time. It was loud but fast! The instructions were clear and it was very user friendly Ease of use:Simple and easy to use

I was forced to use this yesterday. GF went out to roll up windows, before a storm, and didn’t turn off the ignition. The car was so dead that the dome light wouldn’t even glow. Hooked this bad boy up, waited about 20-25 seconds and started right up!!! When I took the until inside to charge back up, it was still at 100%!!!Understand this, I did not trust this thing, I bought it to have on hand in case one of my lawn tractors needed a jump!! I am shocked (pun) at how well this thing works!! Nice unit, emergency light, has the power to start a dead battery, and nice case for everything to fit into!!! Definitely recommend this!

Es muy útil para momentos en.te quedas sin batería,cómodo y muy necesrio

I got this mainly for my riding lawnmower. Every year a need to air up the tires and jump the battery. It jumped the battery instantly with no problem what so ever. It worked better than the jump box it replaced. It also pumped up the tires nicely. After adding air to 4 tires and jumping the battery the battery still read full. The only thing is that the pressures are in BAR so you need to convert to PSI. Also the manual is not that in depth as far as operation. Another thing is that the only "charger" it comes with is a USB to USB-C dongle. I just used my laptop charger. I reckon you could use your phone charger. Had a chance to use it inflating car tires. It's in BAR not PSI and once you do a conversion you don't get exactly 33 PSI but you can do either 32.7 or 33.3 (something like that) I would buy this still knowing everything that I know. my mom had 2 low tires. I had the product out and inflated the tires literally before she knew it in a matter of 2 minutes. LOVE THIS

Works great

Easily started van when needed. Battery was so dead it hardly clicked, hooked this up, started instantly. So convenient!

Very useful
