Used for controller charging stand of the for console, it has output voltage stabilization function, output short circuit protection, and LED light status indication function. It is an application that uses a 5.2V 2A adapter to charge the for console controller. It has an adaptive voltage control system to the safety of device charging. The controller stop charging when it is fully . The smart chip has the function of controlling the voltage strength to prevent excessive voltage from damaging the device. Protection function: 1. Output short circuit protection function: the output is shut down instantly when the output is short circuited. 2. The product has input overvoltage protection function, which can effectively protect the product from damage due to excessive input voltage. When the input voltage is 6.2V, it automatically enter protection mode, and when the input voltage is Less than 5.6V, it power on again and enter the working state. Notes: 1. Please use thick and short cables for charging USB cables and charging board cables, and weld them well to reduce cable loss and improve efficiency. 2. The USB charging cable needs to use a 3A cable to prevent the cable loss from being too high, causing the total power to be too high, resulting in the 5V 2A charger being disconnected due to overcurrent, so that controller cannot be normally. The 7-color light automatically cycles in one circle. If you plug in the power cord during the cycle, the cycle stops and the charging mode is directly entered. The default color is red breathing, and the blue light is always on when fully . After 10 minutes, the blue light goes out (default mode) Colour:Black Material:ABS Package Contents: 1 x Charging Dock for Switch Joycon Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
