Magic in a box!!!
Great starter!! Light weight, plugged it in first time and it did the trick!!! Only took a small portion of the battery life too. Very safe and does the job well, and fast!! This baby saved the day, and was so easy to use. A+++

Small but capable
Smaller than I expected but works well. Started a Subaru Outback with a completely dead battery. But its internal battery power went from 100% to 40% During the starting process, so the advice in the user manual to make sure it is fully charged before trying to start a car with a dead battery is best heeded. I did note that when I went to recharge it after the dead battery start, it had rebounded to 85%. If you have USB charger that can provide 9 volts 2 amps, it recharges pretty quickly. If you only can provide 5V, it will take quite a while to recharge.Overall, I am quite pleased. It is compact and easy to use, and it works!

It works for Heavy Duty Vehicles and Equipment
So happy with this purchase that I came to purchase another one to keep in my daily vehicle!! Got tired of dragging out the jumper cables every time I needed to jump a vehicle or piece of equipment off. This box comes in a nice case, had a partial charge on it and used it on my diesel truck as soon as it arrived so i could move it to the shop to change my batteries. I charged it up and have used it a few times since then on tractors and other equipment that doesn’t get ran daily. It is nice, great value, and convenient. As far as I can tell is going to jump several things before it needs another charge.

Love!
I drive a 5.7L V8 and this has been a godsend when she decides to act up. I love how quick and efficient it is! Once hooked up, my dead engine will turn over in a single pull — for just 6% of battery, too! It never leaves my car and has been through all temps in Ohio without issue. Holds charge well and lasted days when I could only start my van with this jump starter: Well worth the money!!

V8 engines & Can’t use for more than 3 seconds
UPDATE: I’m going to compare this to a 2nd jump starter pack I purchased that was well known and was 40% more expensive.I was going to return the S ZEVZO since it failed to start my Ram 1500 with a 5.7L V8. After a 2nd attempt on another day, it started. It started right away but it dropped the battery to 63% and wouldn’t start it again.I gave it 4 stars because it did start it, when another unit I used would not.Overall, this unit came with a much better, hard sided, zippered case and it started my truck. The more expensive unit had a cheap, nylon storage bag that allowed the flashlight to be accidentally turned on.

Perfect, and Ridiculously Easy to Use
I fiddled with a couple of wrenches and decided there was just no way I was going to extract the dead battery out of my car. Crummy-looking jumper cables were $36. at Walmart; for just a few dollars more I had Amazon deliver this little marvel, and within minutes I was driving down to Advance Auto for a reliably overpriced new battery. Wow, this Jump Starter works great, and it’s lightweight and comes in a nice case. Very nice addition to the “emergency” equipment for a vehicle.

Reliable!
Small compact. I got this because I frequently camp off grid. My truck didn’t start so I pulled it out. Started after first try. Great product. I have since then bought 3 more for family members.

Works, more easily than jumper cables and takes up less space in my trunk.
Just used once, but it worked like a charm for my Mazda. Started fully charged, was at 66% after one brief use. OK, but it worked a lot more easily than my jumper cables. No need to be physically close to the starting engine, so way easier to use on a busy street. It’s just way easier to use than jumper cables. Comes with a nice carry case. It recharged to 99% in about 3 hours
