Instructions for use:
The device is a power supply, with input port, output port, built-in battery, switch button, 5 led lights, the function operation is as follows:
1. The input port supplies power to this power supply, and the output port supplies power to external devices. There are 3 built-in batteries, 550mA/piece, 3.7V battery. The output current is fixed at 1A;
2. Output function, adjustable voltage: (5V, 6.5V, 8V, 9.5V, 11V) every time you double-click the switch, the voltage changes, the first light of 5V is on; only the second light of 6.5V is on; only the third light of 8V is on The light is on; only the fourth light is on for 9.5V; only the fifth light is on for 11V; the lights are on from left to right, and there are 5 lights in five gears, which cycle in turn;
3. When the power is not turned on, short press the power button to display the power (short press for 2~3 seconds): the first light is on, it means the power is less than 20%; the first and second lights are both on for 20~40%; the first, 2, 3 lights are on 40~60% at the same time; the first, 2, 3, and 4 lights are on at 60~80% at the same time; 5 lights are on at 80~100%.
4. Long press the on/off button for 3 seconds to turn on/off, the default 5V output after power-on, short press on the button is the output function-pause, short press again-resume output (the restored voltage is-the working voltage before the pause)
5. Input status display: the LED light flashes when charging the power supply,
The first light is flashing: it means that the charge is less than 20%; when it is more than 20% full, the first light is always on;
The second light is flashing: it means that the charge is over 40%, and the first and second lights are always on;
The 3rd light is flashing: it means that the charge is above 60%, and the 1st, 2nd, and 3rd lights are always on;
The 4th light is flashing: it means that the charge is over 80%, and the 1, 2, 3, and 4 lights are always on;
The 5th light is flashing: it represents full state, and the 5th light is always on;
6. Output status display: When charging external devices, different lights show that the voltage light is always on (for example: the output voltage is 8V, the third light is always on), when the power of this power supply is less than 20%, this The gear position light flashes, and the frequency flashes 3 to 4 times per second. To put it simply: the lights of different gears are always on to represent the voltage; at the same time, if the light is flashing, it not only represents the voltage in the middle, but also represents the power of the power supply is less than 20%
