Description:
The KZ25 is a compact electronic load tester designed for evaluating the performance of USB chargers, power banks, and other DC power sources. It functions as a controllable load, mimicking real-world device power consumption and allowing measurement of various electrical parameters.
Key Features:
- USB interface: Connects directly to USB power sources for testing.
- Adjustable load: Enables simulating different power consumption levels by adjusting the current draw.
- Voltage and current measurement: Displays real-time voltage and current readings of the connected power source.
- Capacity testing: Estimates the total capacity of a power bank by discharging it under controlled load.
- Multiple discharge protocols: Supports triggering various fast charging protocols (QC2.0, QC3.0, AFC, FCP) for compatibility testing.
- LCD display: Provides clear visuals of operating mode, voltage, current, capacity, and other test parameters.
- Reverse polarity protection: Protects the device from damage due to accidental reverse connection.
Technical Specifications
- Input Voltage: Typically DC 4V to 25V (exact range may vary)
- Load Current Range: (typically 0A to 4A)
- Power Dissipation: (typically 25W)
- Display: LCD screen
Applications:
- Testing the output capability and stability of USB chargers and power banks.
- Evaluating the efficiency of power supplies under load.
- Estimating the remaining capacity of power banks.
- Verifying compatibility with various fast charging protocols.
- Educational tool for learning about power electronics and battery testing.
