ماژول ساخت پاوربانک دارای دو خروجی 5V 1A - 2A USB

Power has designs of overcharge, over discharge, short circuit protection, does not need to worry about the time of charging

Intelligent Output. When equipment is fully charged, it will stop charging automatically to prevent from overcharging

Power has multiple safe designs. Output voltage and current is stable, never to damage user's device

Operating temperature range is wide (-20 Celsius—50Clecius),can provide over temperature protection

Function Feature: with a highlight LED lamp (long press or double click power key can start)

Electricity Quantity Display:4 class LED light display electricity quantity, non-operating state will be intelligently off

Charging Display: when charging 0-25% one light is on, other lights off; 25%--50%, the second light flashes, the first light is continuously on;50%-- 75%, the third light flashes, front two lights are continuously on;75%---100%;the fourth light flashes, front three lights are continuously on. And four lights are on charging to 100%.

Mainboard Protection Function: overcharge protection, over discharge protection, overcurrent protection. Power does not need protection board. If you have it, please unload.

Installation Introduction: Circuit board B- connects power negative, B+ connects positive. Don’t inversely connect, it will result in burning of board. Power is series soldering, so please make sure the insulation between power and circuit when install the battery

Double press the switch, flashlight LED light starts, then double press turn it off

Double press starts flashlight, then press once, light will be lighting. Then touch once start SOS mode, and press one more time turn off LED

2A output is not continuous current, it changes according to USB connecting load automatic current output

Insurance resistor battery connects incorrectly, the polarity will burn.
