Works fantastically, battery lasts well.

This works surprisingly well. I'm amazed at how small jump starters are nowadays. It's awesome! Our car is having issues so I've actually had to jump it about 10-15 times the last couple weeks, and that's all on one charge! I keep forgetting to charge the jump starter, but it still has juice. It's pretty easy to charge, sturdy, quick and easy to jump, seems sturdy, and is worth the money. Thankful for it. Read more

Holds a charge for many months

I purchased this in March 2025, that’s 10 months ago. I received it, charged it up and put it behind the seat of my truck. We’re in the middle of a winter storm and it has been below freezing for nearly 24 hours. I went to start my side by side and due to 14 degree temp. It wouldn’t start. I crossed my fingers and got the jump start device out hoping it still had a charge after almost a year sitting in my truck at 14 degrees. It indicated 86% charge and started my UTV up no problem. I give it a 5 out of 5 positive rating. When I took it inside to top off the charge I let it warm to room temp (about 70 degrees) before charging and the charge indicator increased to 94% when warmed up. It holds a charge well and works like a charm. Easy to use. This is definitely a keeper! Read more

It’s a must-have for anyone looking to enhance their roadside emergency preparedness. The S Zevzo Jump Starter is a fantastic tool for any vehicle owner.

I appreciate the built-in LED flashlight and USB ports for charging devices—definitely a plus for emergencies. Overall, it offers great value for its price and has become an essential part of my roadside emergency kit. Highly recommended! Read more

Worked when it was needed

Fully charged the unit after it arrived and it held the charge for 11 months before being used in sub freezing weather. Started my minivan with a totally dead battery on the first attempt. Only annoying thing is the cable with the clamps are pretty short. You need to hold the device closer to the car battery when jumping it. Read more
