Questions about this product
- What are the maximum voltage and current limits this USB tester can safely measure?
- This tester safely measures voltages from 4.5V up to 36V and current up to 8A. It features built-in over-voltage protection within this specified range to prevent damage. Do not exceed these limits, as it could damage both the tester and your connected devices.
- Can I use this tester with USB-C cables and modern fast chargers?
- This tester uses standard USB-A male and female ports for its connections. While it measures up to 36V, you'll need adapters to plug in USB-C cables. It's great for checking standard USB-A power banks, chargers, and electronic devices.
- How does this tool help me diagnose charging problems with my electronics?
- It plugs directly between your charger and your device to show real-time voltage and current. You can instantly see if a power bank is outputting weak power or if a cable is bad. The digital screen refreshes every 300 milliseconds to give you highly accurate, live readings.
