I bought power banks 10 of them from bid or buy. The sellers contacts number is [protected]@yahoo.com I eventually started talking to someone called kiran gopi. I bought these pb's for resale in malawi. They are written 20000 mah capacity and heavily advertised. Discovered all these pbs are a fake imitation, my clients returned them all for a refund!! Some did not even work at all!! The ones that work couldn't even fully charge a single phone!!! This individual has been giving me a run around on email!! I suspect he was buying time so my complaints time could even elapse. Then he even has the audacity to tell me they will replace the one that is not working in my next order!!! Guys like these will destroy bid or buys reputation!! I lost a lot of money because of this person. You cannot allow people selling cheap chinese imitation products on the site!! We want to trust bid or buy.. If that was the case I would rather take a risk and buy straight from chinese sites. Over and above that I bought a car jump starter from 'lees wholesaler' again written 58000 mah which cannot even charge a laptop for 30 mins!! Its a fact its not 58 000 mah yet another scam selling us imitations.
