Purchased four of these (not in this design) to replace my big bulky vehicle jumper that I used to have, which failed on me after several uses. This little unit, despite it’s bigger than your external cell phone charge, which I didn’t mind. It’s small enough that it fits in the glove compartments of all the cars in my family.
I’ve had jumped the car with it, run a fan, charge various devices. I must say, I was impressed.
After jumping the vehicle, the green light on the unit was still at max, and that’s a great thing to know.
This device will also come in handy to run our electrical device during emergency.
This unit weighs 1 lb 12 oz, which is something my daughter didn’t mind putting into her back pack riding on her scooter around college campus. My daughter also found this unit handy as she doesn’t always pay attention to how much battery she’s gotten left in her cell and computer. It also gave her more freedom sitting in a public place, without having to be close to an outlet. Buzzy Mom
