2. Solar charging indication LED
Charging with sunlight, LED turn red.
Four blue LED lights on to indicate lithium capacity, from left to right LED indicate power capacity 25% 50% 75% 100% respectively.
Start up self-checking: the LED lights onby one from left to right and flash once then all lights off after 0.5second, self-checking finished when LED display current power for three seconds.
Without loading state: only one blue LED flash slowly(on for 0.5second, off for 1second)
Loading state: blue LED light on constantly, this product will shut down when battery voltage smaller than 3.3V

3. INPUT
Charging with AC: when you connected with AC(5V/1A), this product will jump into charging state, shut down output, the four blue LED lights on one by one from left to right, the LED will stop lighting if charged to correspondent capacity.
Charging with sunlight: Red LED on, luminosity controlled by sunlight intensity, the more intensity of sunlight, the more bright of LED, it is a float charging state controlled by inner IC, the blue LED will not show rolling indicate

4.OUTPUT
Start up: when output open and no loading, correspondent blue LED to the power capacity will constant on . When the battery capacity left 3.3V, discharge finished and everything off. If you short time press the “PRESS” button once during discharge, rest correspondent capacity indicated LED on for three seconds then off, the one which still on indicate the current power capacity.
Protection: when output current >1.5A(ignore Ipeak), shut down output.

5). Special note
Inner security protection will protect circuit with no output voltage when over charge, over current, short circuit, there are two de-preservation methods
charging with AC110V-240V for several seconds.
face sunlight for several seconds
Please read the manual before using.The incorrect application methods may damage the inbuilt battery and the inside appliances.It can also reduce the battery capacity.
