The MTC4PF with battery is a MattzoTrainController with an integrated, rechargable battery.

The dimensions equal the size of a standard LEGO battery box (8×4 studs = 64mm x 32mm). It has an on/off switch, a status LED, two plugs for LEGO Power Functions train motors, and several connectors for LEDs or other appliances. The battery can be charged via USB.
