- Good price
- Good build quality
- Easy to use
- Dual ports!
- Easy to open for tweaking (see below)
- LED shows it is powered
- Uses an efficient voltage convertor (chopper), so doesn't get very warm
- Does not follow USB spec for adapters!!! Can be fixed however (see below)
- Could be made a bit smaller easily
This adapter does not follow the USB spec for power adapters, but does it the Apple way.
To make it work with other devices, simply open it and short both data pins for each port. I calculated the leak current this causes and it is less than 0.2 mA, so the patch is safe.
Get it, modify it and enjoy it.
If you're not into modifying, get something else - unless your device is from Apple
Apple should be punished HARD for not following the USB specification!!!
