This mobile power supply has a built-in lithium battery protection IC, which has overcurrent, overvoltage, Under voltage protection, and the module is a portable mobile power supply that supports 3V\/1A and 5V\/3A two voltage outputs.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eInstallation of the battery must be determined positive and negative, the board has been clearly marked positive and negative Or Installation errors will burn out the module. The battery voltage works normally from 3.2V to 4.2V. 5V voltage output rated current is 3A, maximum support 3.6A current (not recommended for overload, easy to damage the module, speed up the service life), the output of current depends on the quality of the 18650 battery.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eFeatures:\u003c\/div\u003e\n\u003cdiv\u003eSupports 3V 1A voltage outputs.\u003c\/div\u003e\n\u003cdiv\u003eSupports 5V 3A voltage outputs.\u003c\/div\u003e\n\u003cdiv\u003eMicro USB charging current is 600mA-800mA.\u003c\/div\u003e\n\u003cdiv\u003eSupports up to two 18650 batteries.
