My mains charger has died and I can't find my spare one, so I'm charging from my laptop or my car. Where can I be sure I'm getting a genuine charger? Rainforest and the bay are both selling lots of them around £3 claiming genuine and reviews are mostly positive but mixed, with some saying theirs went bang or stopped charging quite soon after. So I'm not sure. Mobilefun website however is very expensive, between £8 and £18. If it's below £8 is it likely to be fake?
