It features an IPS high-definition color display for clear readings and supports high-power flash charging protocols. This manual provides detailed instructions for its setup, operation, maintenance, and troubleshooting.
2. Product Features
- 6-in-1 Display: Simultaneously shows current, voltage, timing, power, capacity, and electricity.
- IPS High-Definition Color Display: Offers a 160-degree wide viewing angle and high brightness for excellent readability.
- Strong Compatibility: Supports 65W/120W super flash charging protocols when used with original chargers.
- Compact Design: Portable and easy to use for various testing needs.
3. Setup and Connection
The KWS-V30 USB Tester is designed for simple plug-and-play operation. Follow these steps to connect and begin monitoring:
- Identify Ports: The tester has a male USB-A connector on one end and a female USB-A port on the other.
- Connect to Power Source: Plug the male USB-A connector of the KWS-V30 into your USB power source (e.g., wall charger, power bank, computer USB port).
- Connect Device: Plug the USB charging cable of the device you wish to test into the female USB-A port of the KWS-V30.
- Power On: The tester will automatically power on and display readings once connected to a live power source and a device drawing power.
4. Operating Instructions
Once connected, the KWS-V30 will immediately begin displaying real-time data on its IPS color screen. The display shows six key parameters:
- Voltage (V): The electrical potential difference.
- Current (A): The flow rate of electric charge.
- Timing (H): The duration of the charging process in hours.
- Power (W): The rate at which electrical energy is transferred.
- Capacity (mAh): The total charge transferred, typically used for battery capacity.
- Electricity (Wh): The total energy consumed.
The IPS display ensures that all these indicators are visible at a glance, even from wide angles.
The KWS-V30 is compatible with various charging technologies, including 65W/120W super flash charging. For optimal performance and accurate readings with these high-speed charging methods, ensure you are using the original charger provided with your device.
