Description: 100% Brand new and high quality Input: 5V 1A Output: dual output 5V 1A/2A Conversion rate: average 85% With a LED light (long press or double-click the boot button can be opened). Power display: 4 LED lights show power, non-working state intelligent automatic shutdown. Charging display: Charging to 0-25% ,first light flashes, other lights do not light; Charging to 25% - 50%, the second light flash,The first light becomes constant; Charging to 50% - 75% when the third light is flashing, the front two lights to constant light; Charging to 75% ---100% The fourth light flashes, the front three lights turn to constant light, four lights full charge to 100%. Safe design: 1, power design overcharge, over discharge, short circuit protection circuit, do not worry about charging time is too long, free users to worry about. 2, intelligent output, the device is fully charged, the automatic stop charging, to prevent the phone and other overshoot. 3, the power supply has multiple safety design, the output voltage and current stability, will not hurt the user equipment. 4, wide operating temperature range (-20 ℃ -60 ℃), with over-temperature protection. Power display 2A current actual output can be installed inside 6 and 4 18650 battery can also be equipped with polymer lithium battery. Installation Notes: The circuit board B - for the battery negative, B + for the positive. Do not reverse, and then refused to burn the board, the battery is parallel welding. When the battery assembly, pay attention to the insulation between the battery and the circuit board. The battery lead do not touch the circuit board, so as to avoid short circuit.
