Battery Capacity Tester Constant Current Electronic Load USB Power Tester ZK-FX25 4A

Applications:
- To test batteries, power banks, chargers, and various power supplies
- To display voltage, current, accumulated capacity, accumulated time, and temperature
- To set under-voltage threshold, over-voltage threshold, current protection threshold, temperature protection threshold, power protection threshold, capacity threshold, and time threshold. Turn off time and capacity thresholds
- To calibrate voltage and current

Note: Battery is not included.

Features:
- Design with separate power supply. When measuring circuits and display circuits, it does not consume energy at the test end. Measurement is more accurate and reliable.
- LCD screen can display load input voltage, input current, input power, discharge time, discharge maH, product temperature and other information.
- Complete protection mechanisms. Under-voltage protection, over-voltage protection, over-current protection, over-power protection, over temperature protection and the like.
- Manually adjust current via a long potentiometer, without screwdriver or other tools.
- Voltage and current calibration meets your high-precision needs.
- Parameters can be saved when it is power off.
- Applicable to various power supplies (product power supply, chargers, power banks, etc.) for aging or function testing, testing various battery capacity discharge characteristics, desktop small loads.
