Anyone recommendations on these, please?
My son's car often stands for weeks without being used, as he works from home and lives in town.... We put a new battery on before Xmas, but it is obviously nor being charged up enough, and it has been very cold. It's a pain putting it on charge, and because of where he parks, it's not always easy to get access for a jump from another car, so I have been thinking about getting him a jump starter pack.
Can these tiny devices really do the job?
Many thanks
