Input Voltage: AC 100- 240V 50/60HZ
Output Voltage: DC 12V, 3.0A
Product size (Lx Wx H): 14.4x 9.8x 3.9cm
Max charging capacity: Up to 20000mAh
Power adapter: DC 12V, 3.0A (Output), 100- 240V, 50/ 60Hz (Input)
Charging current range (mA): 200, 300, 500, 700, 1000, 1500, 2000
Discharge current range (mA): 200, 300, 500, 700, 1000 (li-ion cell battery only)

Voltage update rate is 30s instead of 60s.
35V charging algorithm is changed to 4.27V.
4.35V charging time can be very long because charging current is regulated in entering the CV stage at 4.12V, which is same as 4.2V type.
New fan cover make better protection for cooling fan.
