This looks like a bargain at Lidle on the 28th. In-car charger with 10 different adaptors plus mini USB, £2:99 http://www.lidl.co.uk/cps/rde/xchg//lidl_uk/hs.xsl/index_26403.htm?offerdate=&ar2=&ERR=noservice
I think these are more useful to a camper owner http://www.lidl.co.uk/cps/rde/xchg/lidl_uk/hs.xsl/index_26404.htm
I should really get round to wiring in a cigarette lighter in my van, then I can use things like this!
