The 12V to 24V PoweredUSB female to female cable is a non-converting, fixed-voltage adapter cable designed to allow 12V PoweredUSB systems to safely reuse 24V-standard PoweredUSB cable assemblies.
This product is not a voltage converter and not bidirectional. The output voltage is always 12V, fully determined by the PoweredUSB host.
Its purpose is to provide mechanical and cabling compatibility, not electrical transformation.

Why This Cable Exists (Design Intent)
In real POS deployments:
- 24V PoweredUSB cables are more common, standardized, and easier to source
- Many POS systems and peripherals still operate at 12V
- PoweredUSB does not support voltage negotiation or auto-detection
This cable was designed to solve a practical system-level problem: How to reuse existing 24V PoweredUSB cabling infrastructure while keeping the entire system strictly at 12V.
The female-to-female structure allows integration with existing male PoweredUSB cables and extensions, without changing system voltage or replacing installed wiring.
⚠️ Critical Engineering Warning
❌ Do NOT connect a 24V PoweredUSB host to this cable
❌ This product provides no over-voltage protection
❌ Female-to-female design does not imply bidirectional safety
✔ This is a passive, voltage-transparent adapter for 12V systems only
