Product Review

Working Voltage: DC 3.5-21V (compatible with Qualcomm QC2.0 A/B protocol 5V/9V/12V/20V)
Constant Discharge Current: 0-3A Continuously Adjustable
(In order to achieve fine constant current, current coarse adjustment 0-3A adjustable; Current trimming +/-0.2A fine tune)
Current Operating Error: less than 2% + 3mA
Continuous Discharge Power: 15W
(At the high voltage (DC20V), the constant discharge current should be less that 1A,
otherwise, the high power will cause a heavy load on the discharge tube) Intelligent temperature control threshold: 55℃/131℉
(If higher than the threshold, the fan will turn on automatically;
if lower than the threshold, the fan will turn off automatically) Type of intelligent temperature control sensor: NTC High sensitive thermistor
Dual Input Interface: USB input/3.5 pitch screw pressing terminal
Power Indicator: blue LED
Fan Speed: 2900/min
Control Chip: constant current chip
Adjustment Potentiometer: metal material, long performance life
Button: alloy material
Discharge Power Tube Types: low resistance, temperature resistance, MOS Field-Effect-Transistor(suitable for high temperature and pressure, the constant current is more stable)
