The bridged data pins are necessary to enable the tablets seen a charger (AC power) instead of a data connection (USB). Data transfer is possible with this adapter NOT.
Not be fooled by the words "For Samsung P1000", it works not only with this old equipment, but also with completely new. In my case, Samsung Galaxy Note 10.1 LTE (N-8020).
Deducted a star because the plug unfortunately relatively easily slipping back out of the socket of the tablets as soon as even the slightest transverse load is applied. This is due to the slightly longer design (compared to the original charger), which is to be inserted by the longer yes again microUSB connector cable including hanging it. Reliable charging only when not under tension adapter, is no matter in what direction, exposed. A device attached charging cable should therefore loosely on the same surface as the rest Tablet, not hanging somewhere etc.
Please use the adapter NOT to load on your PC or notebook, for tablets rich neither 500mA from the USB 2.0 port, yet the 900mA that creates a USB 3.0 port, since this power should not be unlocked without a USB 3.0 device discovery.
Who owns strong MicroUSB charger and would like to share this example with mobile phones and tablets, rather than separate chargers for sale, which is hereby well served.
