تنها با اتصال يک منبع ولتاژ 5 ولتي با درگاه ميکرو USB به ورودي شارژر ميتواند باتري متصل به خروجي را تا 5V شارژ نمايد. اين ماژول بطور کلي براي منابع تغذيه قابل حمل که ازباتري هاي lithium 18650 استفاده ميکنند مناسب است . براي استفاده از اين ماژول نياز به فشردن دکمه ي آن نداريد، با اتصال به موبايل به طور خودکار خروجي خواهيم داشت. جزيان مناسب براي شارژ باتري موبايل به طور خودکار تنظيم ميشود. اين ماژول براي توان کمتر از 0.5 وات و بالاتر از 10.5 مناسب نيست. اين ماژول داراي مدار محافظ نميباشد بنابر اين با توجه به ولتاژ 3 تا 4.2 ولتي نبايد باتري هاي چندتايي سري با يکديگر موازي شوند. باتري بايد داراي ظرفيت 4A حدودي براي دشارژ باشد. ويژگي ها: ورودي : 5V-1A رابط ورودي: پورت مادگي ميکرو USB خروجي : 5V-1A و 5V-2A رابط خروجي: 2× پورت استاندارد مادگي USB A باتري هاي مجاز براي ماژول: باتري هاي ليتيومي 18650 با سر فلت يا باتري ليتيوم پليمري مدار محافظ پلاريته معکوس : ندارد (اتصالات مثبت و منفي با دقت انجام شود.) مدار محافظ overcharge و over discharge براي باتري ليتيومي دارد. مدار محافظ خروجي over current و اتصال کوتاه دارد . داراي چراغ قوه ابعاد برد : 68* 33 * 12ميلي متر

Product details of 5V 2A Power Bank Charger Charging Circuit Module Board Step Up Boost Power Supply Module 2A Dual USB Output 1A Input 100% New and High Quality Power Bank Charger Circuit Board Input Parameter: 5V / 1A Input Interface:micro USBinterface Output Parameter: double USB output: 5V / 2A Conversion Rate: 90% average 4 LEDs Battery Capacity Indicators 1 White LED Flashlight Size : width 2.6 cm, length 6.9 cm Note: The installation and usgae of these modules require some basic knowledge of electronics, if you dont know how to install, please dont buy it. Product Introduction; 1.Input Parameter:5v/1A 2.Input Interface: micro USBinterface 3.Output Parameter: double USB output:5v/2A 4.Conversion Rate:90% average 5.Width 2.6cm, length 6.9cm Battery parallel requirements between 3.2-4.2V can work properly, the maximum can not exceed 200,000 mA Safe Design: 1.Power has designs of overcharge, overdischarge, short circuit protection, does not need to worry about the time of charging 2.Intelligent Output.When equipment is fully charged, it will stop charging automatically to prevent from overcharging 3.Power has multipke safe designs.Output voltage and current is stable, never to damage users device 4.Operating temperature range is wide (-20 Clecius—50Clecius),can provide over tmperature protection Function Feature: with a hightlight 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 lightis off; 25%--50%, the second light flashes,the first light is continously on;50%-- 75%, the third light flashes,front two lights are continuously on;75%---100%;the fourth light flashes, front three lights are continuouly on. And four lights are on charging to 100%. Mainboard Protection Function:overcharge protection, overdischarge protection, overcurrent protection. Power does not need protection board.If you have it, please unload. Installation Introduction: 1.Circuit board B- connects power negative, B+ connects positive.Dont 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 2.Double press the switch,flashlight LED light starts,then double press tyrn it off 3.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 4.2A output is not continuous current,it changes according to USB connecting load automatic current output 5.Insurance reisitor.If battery connects incorrectly,the polarity will burn.
