5Pcs Micro USB 5V 1A Lithium Li-ion Battery Charging Module 18650 Battery Charger Board 3.7V/4.2V to 5V Booster Power Supply Module DIY Mobile Power Bank

QINIZX #ad - Note: the positive pole of the battery is connected to B+ and the negative pole is connected to B-, do not reverse it. Other aa batteries, and lifepo4 batteries cannot be connected, NiCad batteries, AAA batteries, NiMH batteries, and the lithium battery voltage is lower than 2.

75v or higher than 4. 2v must not be accessed. If it is reversed, it will burn out!!!! activate the usb output port: after the battery welded on the booster board, use the charger and charging cable to charge the battery for 2 seconds to activate the motherboard. At this time, and then the USB output port will have 5V voltage. Note that this booster board can only access 2. 75-4. 2v lithium li-ion batteries. Input 2. 75-4. 2v 05a, output 5v 1A; cable length 2. 20inch. 2-led indicator: the red light is always on when charging, even if the phone is not charging, BUT because there is always a 5V output after the activation of the output, there is always a blue light flash; when used to charge the phone, so the full charge depends on the time; The Blue light on discharge, the external discharge current becomes larger and the blue light will be brighter than when it is empty.

For voltage output, the blue light on the board will light up slightly, The correct voltage for measuring the red and black solder joints should be 2.
