you know those things you keep on dash to keep the battery topped up, reckon that would work inside a garage....if the roof is clear perspex??

dont have power in my garage, and the battery on the escort goes flat quickly.

 

It would be a guess, what about puttin a panel on the gar roof?

 

Mate, I had one and was one of the worst things I bought, never charged properly and was a waste of time and £. Stick to a mains one if you can. Thanks.

 

Assuming your battery is in good condition ,yeah they do work . Used one for last 3 years on various cars and spare batterys in shed and never had a problem . I do have it on outside wall/ roof of garage/ shed and feed wire inside. Use it on my pick up when i know i am not going to use it for a few weeks . Just leave it on dash and feed wire under bonnet ,but it is parked outside all time.
