following on from the bargain rechargeable battery packs for all sorts of devices, the XP1/2/4000, i noticed this on the shelf. there was no price so got it price checked and turned out to be £2.50. (purchased from halifax store). just checked online price at tesco still £40.
it seems all energiser energi products at tesco are at vastly reduced prices. the full spec/product details are available at the following link http://www.energizerpowerpacks.com/ph/products/ap1000/
