I have not yet used this jumper to start a car, but based on past experience with a similar model I owned, I am confident it will perform well. I did not give a 5-star rating due to a couple of minor issues: It arrived charged at 73%, which is acceptable, but reaching the final 100% took quite a long time—longer than I anticipated. I also expected both the jump starter unit itself and the carrying case to be a little smaller.

Made well and came 75% charged already. Made well and starts my truck and zero turn mowers. Does need a little recovering time between a long crank time of 30 sec. but its ready again.

This Jump Starter is a solid and reliable tool. It easily jump-started my 6.0L gas engine, and its compact size makes it easy to store in the car. The LCD screen is clear, showing battery status, and the LED light is great for nighttime use. I also love that it doubles as a power bank, so that I also easily charge my electronic devices. Overall, it's a great value for its power and features.
