functional description
A，functional specification
1 the first use， the need to use the device to activate the device to activate or press the button for more than 2 seconds; trigger button once， mobile power on， the power will be real-time monitoring of battery voltage， and display power.
2 starting in the process of real-time monitoring of load current. If there is a load and current is greater than 50mA， the current battery indicator light flashes. If the load current is less than 50mA， then the current battery indicator is often bright， and the start time， the continuous 20s load is less than 50mA， then turn off the mobile power. If the load current is greater than 50mA， the timer is cleared.
3 after the start button， all superimposed products will wake up and display the current power and output.
4 products can be used alone or more than a single use， can be a separate charge can also be superimposed together for charging
5 conversion efficiency of 87% products;
Two，Electric quantity display
Four power indicator lamp charging below 25% D1-D4 flash in sequence; more than 25% D1 often bright carnosine D2 D4 flashing in turn; 50% D1， D2 often bright serine D3-D4 flash in sequence; flash above 75% D1， D2， D3 often bright carnosine D4; full， four lights long bright.
