“Does the job perfectly. With lockdown, my car has been sitting idle on the drive for long periods at a time, & wouldn't start. This did the trick with far less hassle than jump leads. I'm not sure how many jump starts it will do without needing to recharge, but after a couple of uses, it was still showing all 4 lights.”

“Didn't work from day 1. Clarke still have it and I am out of pocket until it either returns or I get my money back.”

“The Charger arrived promptly. I have tried all functions with the exception of the prime reason of purchase and they all work as specified. The jump start is as yet untested as I have had no reason to try it. When such time as my car battery fails on me will be the crunch, but I have no reason to doubt it will perform as specified.”

“An excellent piece of kit especially if you drive an older vehicle. I have a 1966 Ford and a 1987 Vauxhall, so apart from the jump start ability the USB facility for dash cams and phone power is a bonus plus it's compact size. Definitely a Winner.”
