MHL Adapter/Charging issues
How are these working out for people? I picked up the official Samsung MHL adapter and have mixed feelings so far. It works pretty well most of the time. However, the video output cuts out randomly and the battery doesn't produce a positive charge while connected. I recently learned this is due to the fact that most MHL adapters will only allow a 500mA charge. I tested this by watching Netflix, checking email and doing some web browsing. After 30 minutes, my 100% battery was now down to 80%. That's crazy. How do they expect us to use this for extended periods? Essentially I would have a dead battery in less than an hour and a half. I wouldn't even make it through one Netflix movie.
Anyway, has anyone found an MHL adapter that actually produces a positive charge while in use? If not, I guess I'll wait for the mythical dock that uses the pogo pins, if it ever sees the light of day.
