I was sent the S ZEVZO H021 Jump Starter and tested it on my own car to see if it could start it. It did.
In this S ZEVZO jump starter review, I’ll cover the case, charging, the power bank and flashlight, and jump starting my car, the pros and cons, and who it’s for.

What Is the S ZEVZO H021 Jump Starter?

The Case
It comes with a carrying case that holds the jump starter and all the cables snugly.
Charging It
It charges with the included USB-C cable. You’ll need your own power adapter for the wall.
Power Bank and Flashlight
Because of the 74Wh capacity, I used it to charge my battery bank and AirPods. The flashlight is super bright and lights up dark areas well.
Jump Starting My Car
Plug the clamp cables into the jump starter, and you’ll get flashing green and red lights for standby. Pop the hood, connect negative to negative and positive to positive. A red light and a beep mean the polarity is reversed, so just swap them. Then my engine started right up. Once it’s running, take the clamps off.
Things to Consider Before Buying
- Wall adapter: A USB-C power adapter isn’t included.
- Recharge after use: Top it up after each jump so it’s ready next time.
