Frequently Asked Questions
Q: What devices are compatible with this USB-C to DC 5.5x2.5mm power cable?
A: This cable is compatible with any device that uses a standard 5.5x2.5mm DC barrel jack connector, such as LED lights, portable speakers, Wi-Fi routers, surveillance cameras, and certain laptops. Make sure your device uses center-positive polarity and operates at a voltage your USB-C power source can deliver (9V, 12V, 15V, or 20V).
Q: Does this cable convert or regulate voltage?
A: No — this is a pass-through adapter cable, not a voltage converter or regulator. It delivers exactly the voltage output by your USB-C power source. If your USB-C charger outputs 12V, the DC connector will output 12V. Always match the required voltage of your device with your power source before use.
Q: What is the maximum current this cable supports?
A: This cable supports up to 3A of current, making it suitable for powering a wide range of low-to-mid power devices via a compatible USB-C PD (Power Delivery) power source.
Q: Is this cable USB 3.0 compatible?
A: The cable uses a USB-C female connector rated for USB 2.0. Since this is a power-only cable (not a data cable), USB version does not affect its performance for power delivery purposes.
