Since most of the Skyworth boxes do not have a switch button (like the A810), the box can only be put into standby by the remote control, or the power supply can only be pulled frequently. So some users will choose to connect the box's power input USB port to the TV, so that the box can be switched on and off with the TV, it feels very convenient.
But in fact, the damage to the box is very great. Skyworth box power adapters come in two sizes, one is 5V/2A and one is 12V/1A. The current maximum output current of the LCD TV USB interface is 1.5A. In this case, if a TV is used to supply power to the Skyworth box, the output current will not be the same, which will cause adverse effects on the box and the TV itself and will affect the life of the Skyworth box! Therefore, when using the Skyworth box, try not to connect the TV directly for convenience. It is better to follow the traditional connection method!
