Hi everyone I just got the S6 and when I plug it into the included charger it says fast charging and it charges it to full in like an hour. I have a few Anker Chargers from when I had an iPhone and the big thing with them if they always both that they also use 2 amps and charge devices at the fastest speed possible. Whenever I plug into it though it just says cable charging 2.5 hours until full so it doesn't seem like it charges any faster than anything else. Does that mean that only the official Samsung charger does the fast charging for this phone? I wanted to buy some extra chargers but if these ones I have right now won't do fast charging when they say they will, then I'm assuming none but the official would. Thanks!
