Frequently Asked Questions

Q: What devices is this USB to 12V power cable compatible with?

A: This cable is designed for small electronic devices that require a 12V DC power input — such as certain broadband routers, modems, and similar low-power equipment. Always verify your device's voltage requirement, connector size, and center polarity before use.

Q: How does the selectable polarity feature work?

A: The 2-pin output connector can be flipped or reversed to switch between center-positive and center-negative configurations. Always confirm your device's required polarity (usually printed on its label) before connecting to avoid damage.

Q: Can I use this cable with a USB power bank?

A: Yes — as long as your power bank provides a standard 5V USB-A output, this cable can draw from it to supply 12V to your compatible device. Note that the power delivery capability of your USB source may limit the current available, so check your device's power draw requirements.

Q: What is the cable length?

A: The cable is approximately 115 cm (about 45.28 inches / 3.8 feet) long, offering enough reach for flexible setup around a desk or in a travel bag. Please allow 1–2 cm variance due to manual measurement.
