Frequently Asked Questions
Q: What devices can I test with this USB-C power meter?
A: The KWS-1802C USB-C power meter works with any USB Type-C device, including smartphones, tablets, laptops, power banks, USB hubs, and other digital accessories. It can measure no-load power supplies, voltage loads, and USB terminal devices — making it suitable for home users, factory technicians, and laboratory professionals alike.
Q: Does the USB-C power meter require batteries or an external power supply?
A: No — this meter is completely plug-and-play. It draws power directly from the USB-C connection being tested, so there is no need for batteries or any external power supply. Simply insert it between your charger and device to start measuring instantly.
Q: What is bidirectional testing and why does it matter?
A: Bidirectional testing means the meter can detect and display current flowing in both directions — whether power is flowing into a device (charging) or out of it (discharging). This is especially useful for testing power banks and other devices that can both receive and deliver power, giving you a complete picture of electrical flow in any scenario.
