Just bought one of those battery powered jump starters with built in compressor for inflating tyres, lamp and 12V lighter socket for powering other things, from maplin electronics for £20 if anyone is interested (17AH battery).

Mate, they are gash! I bought one very similar to these a while back & after 6 months, the battery was knackered. Even when new, it would barely turn over a Pug 1.9gti engine. I hope yours is better!

I have been using one from Maplin about 3 years -- excellent only thing to watch is the socket the mains charger pugs into can sometimes give a bad connection resulting in an incomplete charge.

I bought one the other week, for £20 was worth a punt.

My local aldi has some in for 24 quid still. I had a blackspur one for a while which worked well. The compressor thing was handy. I left it flat for too long and the battery went. Make sure you flatten it and charge it every so often if you dont use it much,.

my local trade centre sells them for £13+vat. Ive never sucessfully used it though, but luckily i also bought some 35mm jump leads for a similar bargain price!

got an sip jump pack which hasn't been charged sinse i was building my indy yet somehow still does the biz!
