Notice:

• The current of input should be greater than output.
• The board may be into Protection mode when operating (by wrong touch, wrong connection, short circuit, etc.). Please eliminate the problem and input 5V to the charge port, the output will be reactivated.
• If the power source was off and the power is still leaking, please parallel (shunt) a 1K resistance at the 5V input port.
• When welding, please ensure the Electric welding iron with ground wire, and it's better if wearing anti-static gloves.

• When the power is re-on, it will supply power to the load from power supply source and also charge the battery.

Wiring (Please check the last image of this item to locate these ports):

• Input: 5V, Micro USB Port or the Positive (+) and Negative (-) near the Micro USB Port, please choose 1 of them.
• UPS Output: marked as "UPS +" and "UPS -", at the other end of the input end.
• Battery Output: in the middle of the board. You can weld a battery case to connect the battery, or just weld wires to connect other battery.
• USP Output Switch: in the middle of the board, short the weld joint to activate the UPS output function, or use jump wire and switch button (not including in the package)
• If use it as a mobile power bank, an extra switch button is recommended. And after the first test, remove the output LED indicator can reduce about 10 to 20 mA of current loss.
