DIY Powerbank Power Bank Charger Module Dual USB Output 5V 2A with LED Indicator

Power Bank Charger Module Dual USB Output 5V 2A with LED Indicator

Product Introduction:
1.Input Parameter:5v/1A
2.Input Interface:V8 interface micro USB
3.Output Parameter: double USB output:5v/2A 
4.Conversion Rate:90% average

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 user's device
4.Operating temperature range is wide （-20℃—50℃）,can provide over temperature 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.

Power Capacity Instructions:0-25%(one LED),25%-50%(two LED),50%-75%(three LED),75%-100%(four LED).

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.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
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.

Rechargeable battery requirements:
Available battery: 18650 battery, mobile phone battery, flat battery, MP3 battery, etc. 3.7V-4.2V polymer lithium battery, can be powered by single section (chip), or multi-section (chip) parallel power supply (does not support series, can not be connected in series ). (Note: increase capacity in parallel, increase voltage in series, can only be used in parallel!)
You can connect 2-6 knots of 18650 batteries in parallel! ! !
Unavailable battery: dry battery, battery, 1.2V rechargeable battery, nickel hydrogen battery, 3.2V iron lithium polymer lithium battery.

NOTE : Untuk stok saat ini, cara menyalakan LED agak sulit / tricky jadi dianggap tanpa LED. untuk fungsi yang lain (charger dan output) normal
