I must say I love the part. I have not connected via a power supply, but directly on the LED TV USB, so when I look TV, then my two remotes are equal loaded (halt will last longer than with a 2A power supply). After about 1.5 hours, the remotes are full.
Looks as "dock" is not bad.
But I must admit that after some time with me probably one of the two batteries has given up the ghost and is therefore no longer load properly.
