I love this tech gadget. Better than using the regular jumper cable and requiring a car to jumpstart.
I have a vehicle, a van, sitting more than 2 years and the battery had died. Had a friend come jumpstart for me since I wasn't fond of using my own little car battery.
When I got this, I was nervous about the safety of using it so my friend came out to help in case I got jolted or something.
I wasn't sure it would be strong enough to jumpstart it. But it all took just a few minutes. Usually I have to wait til the battery was fed a bit, but the van started right up.
Charge this first then watch magic happen. You can see the power level on the gadget. Has a bag to carry it so you could store in the car if needed.
In the past, I got approached by strangers needing a jumpstart. I can impress them when I get to use it.
