Usage:

  • On the first use, the mental knob of the potentiometer on the USB adjustable constant current electronic load device should turn to the end in counter-clockwise direction. Then plug it to a USB current and voltage detector whose one side has plugged to power bank or charger. Slowly adjust the knob in clockwise direction, in order to the reach the detector display the value you need to discharge and aging.  

Product Features:

  • Intelligent temperature control air cooling load makes discharged current not fluctuate with the change of voltage.
  • Current can 0~3.5A wide range stepless adjustable constant current discharge.
  • The module is suitable for high voltage discharge load of Qualcomm QC2.0 protocol and it is also almost suitable for all the products with USB output interface on the market. Increase terminal column, the compatibility is stronger and the application scope is wider.

Package Includes:

  • 1 × USB Adjustable Constant Current Electronic Load
