DC Barrel Plug Adapter, Female 2.1mm x 5.5mm to Male 0.7mm x 2.5mm, 18 AWG | RC-X0725
DC Barrel Plug Adapter: 2.1mm x 5.5mm Female to 0.7mm x 2.5mm Male
Part RC-X0725 connects a power supply's 2.1mm x 5.5mm male barrel plug to equipment accepting a 0.7mm x 2.5mm male barrel plug. Its compact pigtail uses 18 AWG wire and an approximately 3-inch cable to adapt the connector size without cutting or soldering.
Important compatibility check: Matching connector sizes does not establish electrical compatibility. Confirm your equipment's required DC voltage, current, polarity, connector insertion length, and clearance before connecting. Do not assume center-positive, center-negative, or polarity-preserving wiring from connector dimensions alone. Verify the adapter's wiring and resulting device-end polarity before use.
Technical Specifications

Applications and Replacement Guidance
Use Part RC-X0725 for connector-size adaptation only after verifying the power supply, adapter, and equipment are electrically compatible. It provides a smaller male barrel connection for equipment requiring a 0.7mm x 2.5mm plug. Confirm insertion length and clearance as well as diameter. No specific camera, router, radio-controlled device, or other equipment compatibility is claimed.
Compatibility Checklist
- Your power supply has a compatible 2.1mm x 5.5mm male barrel plug.
- Your equipment accepts a 0.7mm x 2.5mm male barrel plug with suitable insertion length and clearance.
- The power supply's DC voltage and polarity match the equipment requirements.
- The power supply has sufficient current capacity.
- The adapter's allowable voltage and current are verified for the installation; 18 AWG alone does not establish a complete assembly rating.
- The adapter's wiring is verified, and the resulting device-end polarity is correct.
Frequently Asked Questions
Which direction does this adapter convert?
Part RC-X0725 accepts a 2.1mm x 5.5mm male power-supply plug in its female socket and provides a 0.7mm x 2.5mm straight male barrel plug for the device connection.
Does it change voltage or convert AC to DC?
This is a connector conversion pigtail, not a voltage converter, regulator, or AC-to-DC power supply. Use a DC power source that already meets the equipment's electrical requirements.
Does it preserve or reverse polarity?
A polarity-preserving or polarity-reversing wiring claim has not been verified for this listing. Check the adapter's wiring and polarity at the device-end plug before connecting equipment. Connector sizes alone do not establish polarity.
Will it fit any device with a small power jack?
No. Verify the exact 0.7mm inside diameter and 2.5mm outside diameter, required insertion length, clearance, DC voltage, current, and polarity. A small-looking connector or device type alone does not establish compatibility.
Do I need to solder it, and how long is the cable?
No soldering is required; both ends use plug-in barrel connections. The cable length is approximately 3 inches. Verify compatibility before connecting power.
