The AC/ USB/ DC output switch can be normally turned on only when the power switch is turned on; if you need to charge the electronic device through AC/ DC/ ECO, please turn on the corresponding switch (USB/DC output is controlled by the DC switch). Once the switch is turned on, the LCD lights up and displays the corresponding data.
Press the main power switch to turn on or off the outdoor power supply.
ECO mode: When the main power switch is turned on, the ECO switch will automatically turn on, and the ECO mode will start. After no-load running for a period of time, it will automatically shut down (please consult customer service personnel for details). You can press the ECO button (the indicator is off) to disable the auto sleep function.
