“Didn't work when I really needed it. 3.0 diesel engine. Started smoking during boost use, another attempt got an error saying the battery was at 188% and flashing. Tried again the next day no luck, just wasted my time and money with this gimmick product. The clamps are too large and bulky to get into tight spaces so it was difficult connect to the battery, also the cables are too short and results in a lot of faffing about trying to get a decent connection in limited spaces due to the claims and short wire. Maybe for a small car it might work absolutely useless for a van which it claimed it was suitable for”

There’s no doubting the quality, it’s practicality or features but until the temperature drops in the winter and it has to be used in anger, then the real test will taken.
At the moment it has been fully charged and I will monitor how long it retains this whilst on “standby”. That will give me an idea as to how long it can sit in my vehicle between charges.”
