S ZEVZO ET03 Car Jump Starter 4000A Jump Starter Battery Pack for Up to 8.0L Gas and 7.0L Diesel Engines, 74Wh Portable 12V Jump Box with USB Ports, LCD Display, Storage Case, and LED Light

I love this jump box!! It is super handy, last good and easy to use. It is super handy on the farm and will even start my 6 cylinder diesel tractor!

I was skeptical until I used this. It works very well. When they say your vehicle will start immediately , they aren't kidding. It is very well constructed and sturdy. I would recommend that everyone gets one for themselves or a loved one.

This thing has saved my tail on more than one occasion. Had a problem with my main fuse and it was causing my battery to not be charged while driving. I was able to give myself a jump to get home everyday until I figured out what the problem was. Love it because I really didn't want to ever have to rely on the kindness of a stranger to get me out of a bad situation. At full charge I was able to jump myself 3 times and it still said there was 70% charge left. It's small and fits in my glove box. It's super easy to use too.

Wonderful little tool! Works exactly as advertised. Battery completely dead at 7 degrees fahrenheit turned it right over. Life saver.

Works well and I'm glad I bought it. I like that it is much more compact and easier to use than a different kind I had previously. If you buy it, just make sure it is always charged and ready to use when you need it.

Easy to use. Good battery life so far. Small enough to carry with you in car. Lightweight

We bought this for my daughter's car as it started having troubles and needing jumps. Does exactly as advertised - and holds a "shocking" amount of charges for it's size, too! The built-in flashlight is a nice touch, and the ability to charge a phone or other device is a great safety feature if you're stuck somewhere, especially in winter. I have now also used it on my toyota hybrid, when the starter battery went bad - saved my bacon on a cold Thanksgiving morning!

Absolutely top notch product! Small, easy to use and effective. One of our cars is an old beater that was having electrical system issues. So I've had the opportunity/curse of having to use this three times in the last few weeks. Each time it has started up the car instantly, including on some nasty cold mornings. I'd hate to think what I would have had to do without it. But remember to recharge it -- these three jumps have lowered the device from 99% charged to only 4%. Fortunately that's easy to do inside the house altho it takes a few hours. In theory you can hook it up to an in-vehicle USB hub to keep it charged, altho that is not an option in my case. Regardless, I'm very pleased and glad to have it!
