Microcomputer IC controls charging process: CC/CV/Trickle charging, to make sure the battery is full charged and won’t be over charged; each slot controls independently; Mixed charging mode.
LCD instantly shows the charging process
Compatibility: various kinds of cylindrical chargeable batteries (Diameter: below 32mm, height: 34-75mm)
Charge 3.7V（3.6V）and 1.2V Ni-MH/Ni-CD batteries
Adopt Negative voltage control technology to improve charge efficiency.
Protect opposite connection and short circuit. (At this time, the four LEDs corresponding to the slot flash simultaneously.)
Input with Micro USB and TYPE-C
QC fast charging , corresponding to high current mode
Activate automatically for Li-ion batteries with protection board, which are instantaneous short circuit.
Not charging Ni-MH(<0.4V), at this time, the four LEDs corresponding to the slot flash simultaneously.
4.1 Input:DC 5V 2A 9V 2A (QC)
4.2 Output :DC 4.2V±0.02V 1.5A*2 3.0A*1(QC) 1.0A*1 DC 1.53V±0.02V 1A±30mA*2
4.3 Charging Instruction Mode
A. If don’t plug in, LED shows nothing.
B. Plug one end of the adapter into the charger. Plug the other end of the cord into a wall outlet; all LED indicators twinkle and go off. The logo light is always on.( the white LED represent normal input model, the blue LED represent QC fast charging mode.)
C. when the battery put in to the charger, the charger discern automatically Li-ion battery and Ni-MH, and then the charger into charging mode, and the LED shows battery power.
D. Battery symbol displays dynamically
①Present charging status
②Present battery capacity percentage as follows:
a.The first LED flash battery power <25%
b.The first LED is on and the second LED flash battery power ≥25%
c.The first and second LED are on and the third LED flash battery power ≥50%
d.The first, second and third LED are on and the fourth LED flash battery power ≥75%
e.Four LEDs are on meanwhile, the battery was charged full battery power ≥100%
