It's not hype, just kind of oddly named. Last time I heard 'fast charger' was in the early 2000's with my Nokia. It's probably just a 2A charger, where most chargers that come with phones are 1A, and most that come with tablets are 2A, but a 2A charger will still work on a phone that usually gets a 1A charge, and it will charge faster. If you put the device into airplane mode, it will charge even faster yet.
