1A charging current at fixed micro USB charging cable
2.1A charging current to the USB output.
The charging current for the micro USB cable can I find with 1A well chosen, as this is the standard charging current of most phones.
With 2.1A, however, can be more than the additional USB Beech also Tablets safely and quickly invite.
The adapter has a tight fit in the car and does not wobble. The fixed cable to charge the phone I find very handy, so you have to plug in any separate cable. After use, the adapter can be easily stuck left or keep it in the glove compartment.
All in all a good adapter for a good price.
