Review on Black Otterbox USB Wall Charger - Retail Packaging by Jennifer Davis

But. (and I know it's probably an unfair viewing angle) this doesn't work for Samsung Fast Charging. It's a beautiful, elegant, black charging box. Feels solid like any OtterBox product. but apparently even when charging with 2.1a it doesn't have any internal circuit boards/whatever to provide the adaptive fast charging capabilities my Note5 needs to fast charge. My roommate's HTC charges fast with it and I have yet to try to charge my Nexus 6 with it, so even faster charging is possible with the block. Beware of Samsung users. This box does not increase loading speed.
