Recommend a jump starter

[MingeBlue]

Went out to car this eve to find flat battery my own fault left interior on, I seem to do this alot. I want one of those jump starter battery pack things so I dont have to depend on others any one recommend one, its a 1.8t ? I dont want to spend big £ but enough to get something decent.

This probably doesn't help you. But I've got loads of spare batteries in the garage so I just use one of them.
Have a 240v converter to charge them when they're dead

Working it out I hadnt driven car for a week so light must of been on for that time so 7 day drain. Do you recon the battery might be toast now ?
