Description: High-performance transistor circuit expend low power. When you do not need to synchronize, you can use the manual switch or the secondary power switch. It have power indicator, when the secondary power supply the emitting diode will turn light. With the help of large 4PIN output and the shop's wire, you can switch out a variety of power interfaces, take full advantage of the power efficiency. Specification: Material: Plastic ABS Size: Approx. 6.9 x 3 x 1.6 cm / 2.72 x 1.18 x 0.63 inch Package Includes: 1 Piece Transfer card Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
