Technical Parameters:
  • Voltage Range: DC 3~21V (compatible with quick charging such as the Qualcomm QC2.0, 5V/9V/12V/20V, Qualcomm QC3.0, BC 1.2, MTK-PE and Apple 2.4A etc.)
  • Current Range: 0~3A continuously adjustable (roughly adjust 0~3A by per 0.1A , precisely adjust by per 0.01A)
  • Accumulative Capacitance Range: 0~99999mAH
  • Accumulative Electric Energy Range: 0~999.99Wh
  • Power Range: 0-35W( the continuous discharging power is less than 35W)
  • Accumulative Time Counting: 0~1000h
  • Voltage Testing Deviation: 0.01V
  • Threshold of Smart Temperature Control: when the temperature﹥55°c(131°F), the fan would automatically work; when﹤45°c(113°F), the fan would automatically turn back off
  • Detector of Smart Temperature Control: premium NTC thermistor
  • Switching Regulator IC Frequency for Fan: 1.2MHZ
  • Power Supply Indicator: blue light when powering on
  • Fan Speed: 6000/min, 40 × 40 × 20mm
  • Controlling Chip: constant current chip
  • Radiator: 6063 aerospace aluminum radiator, 40×40×10mm
  • Adjustment Potentiometer: durable metal potentiometer
  • Discharging Power Tube: voltage-controlled low-impedance MOSFET (more stable constant current when is on high voltage, high temperature)
  • Operating Temperature: ﹣10°c ~﹢65°c (14-149°F)
  • Product Dimensions: 100mm×48mm×30mm
Warm Tips:
  • When operating a burn-in test discharging, the resistor would get hot, about at 80~85℃, so please note not to be hurt by the heat.
Package Includes:
  • 1 × USB Adjustable Constant Current Electronic Load (USB Tester/Multifunction Digital Meter)
