Note: B+ and B- of the boosted battery must not be reversed.

Application: All 3.7-4.2V rechargeable lithium batteries, such as mobile phone battery flat battery 18650 battery and so on!

Can be connected to a lithium battery or parallel multi-cell lithium battery

Lithium battery positive electrode connected to B+      lithium battery negative electrode connected to B-

Attention!!!

Note: B+ and B- of the boosted battery must not be reversed.

The first use requires a Micro USB port to activate once

Tips: This shop has a large number of lithium batteries for sale, you can buy them together! !

 Charging indication: the charging display will show the IN letter

Output load indication: long press the LED light button after the load is turned on, the output starts, the display will show the OUT letter and the relative output voltage and current 5V1A or 5V2.1A

Protection function: The protection circuit of the boosted lithium battery has been integrated to prevent over-discharge, over-charge and overload.

Note: B+ and B- of the boosted battery must not be reversed.

Can be connected to a lithium battery or parallel multi-cell lithium battery

Lithium battery positive electrode connected to B+ lithium battery negative electrode connected to B-

Attention!!!

The first time you need to activate the Micro USB port, you will charge it for 1 minute before using it.
