Well more of a backup charger that doesn't need to be plugged into the mains. My locker is about a foot cubed metal thing amongst many others in the ladies locker room without it's own power supply unfortunately ;)
My reason for asking is I used to have one I can't remember where I got it from but it was cheap and it didn't work! I definitely don't want a wind up after reading that it took someone an hour of winding it to get the phone to turn on then it went straight off again. I've seen some on the net but haven't seen one with a good review.
Thanks for the links there, they all look pretty good.
I work at Boots as a lowly sales monkey and therefore do not have my own desk/use of electricity there. The locker thing was merely an example, be good to keep in my bag at all times. I broke down on the M6 once and only had 3% battery on my phone, a charger would've been good then!
Acethetroll, it's not like they won't let me near electricity, they just dont want to be paying out for me to charge up my phone, also If I leave my phone charging in any old place it will get stolen. I wish I'd never asked the damn question now lol
