⚠ Important – Please Read Before Use
This cable is designed for use only with devices confirmed to require a 12V DC input at a low power draw. Before connecting, always verify your device's:
- Required input voltage (must be 12V DC)
- Correct connector tip size and fit
- Center polarity requirement (center-positive or center-negative)
- Power consumption — ensure it is within the USB source's output capability
Connecting this cable to incompatible devices or exceeding the USB source's rated output may result in device damage. Always check device documentation before use.

Frequently Asked Questions
Q: What devices is this USB to 12V power cable compatible with?
A: This cable is compatible with any device that operates on a 12V DC input at a low power draw and accepts one of the included DC connector tips. Common compatible devices include small broadband routers, wireless adapters, and other low-wattage 12V-rated electronics. Always confirm your device's voltage, connector size, and polarity before use.
Q: How does the selectable polarity feature work?
A: The 2-pin output connector on this cable can be reversed in its housing to switch between center-positive and center-negative polarity. This means you can adapt a single cable to suit two different device polarity requirements — just check your device's specification and orient the connector accordingly before plugging in.
Q: Does the cable work with any USB-A power source?
A: The cable requires a USB-A port capable of supplying 5V at sufficient current. However, since this is a step-up converter, the output power is limited by the USB source's rated output. Always ensure your USB power source (wall adapter, power bank, etc.) can deliver enough current to support your connected 12V device without overloading the USB port.
Q: How many connector tips are included?
A: Depending on the variant selected, the set includes either 8 or 9 interchangeable DC connector tips, giving you broad compatibility across different 12V device connector sizes.
