I had a previous model of this unit which was at the old "slow" charge rate and was so pleased to get the new and improved version. They even fixed the few issues I had with the older version. This model has the charging cable in back instead of sticking out the side, the LED indication light is much dimmer, although larger, which makes it easy to see where to place the phone in a dark room and not act like a flashlight while trying to sleep.
The display angle is acceptable, it works well through a case, although I haven't tried a Defender case yet and the fit is more secure than even the Samsung charger..
The unit uses a microUSB connector and a 2.1A adapter, not included.
