Salloum wroteAs you said its 30$ at CTC but it does include a cable (a 2 meter one). As someone with experience in this I would advise to bite the bullet and pay 30$ at CTC because the S6 has a crap battery anyway so you probably recharge your phone a lot, and using a fake charger will completely ruin your battery which isn't user replaceable.
Can a bad charger really ruin your battery? I was under the impression that your battery extracts at its own set rate, regardless of the voltage output of the charger.
