Power adapter converter

This cable converts a 5.5x2.1mm barrel jack into a USB female port so a standard barrel power adapter can charge USB devices. It suits installers who need to power cameras or other USB gear from an existing DC supply. The 12cm length keeps the link short and tidy. Two pieces are included in the pack.

Barrel jack fit

The connector measures 5.5mm outer diameter and 2.1mm inner diameter; matching this size to the source adapter is the single specification that decides compatibility. A mismatched barrel will not seat securely and will not deliver power. Verify the dimensions on the original charger before ordering.

Sustained current delivery

With a 4mm wire diameter the cable handles continuous charging current without excessive voltage drop over the 4.72 inch run. The short length minimises resistance so connected USB devices receive stable power during extended use. No active electronics are present, so thermal limits follow the source adapter rating.

Questions about this item

What does the 5.5x2.1mm barrel jack mean when I plug it into my power supply?

The 5.5mm outer and 2.1mm inner dimensions match standard barrel connectors on many DC adapters, so the cable accepts the tip from your existing supply.

What does the USB female port cap in practice?

The USB female port passes through whatever voltage and current the connected barrel power supply delivers; it does not regulate or limit output itself.

Will the 12cm length and 4mm wire diameter fit inside my camera housing?

At 12cm including plugs and 4mm overall cable thickness, the assembly is compact enough for most small enclosures and camera mounts.
