Connector Type: DC Barrel Plug (Male)
Size: 3.4mm (Outer Diameter) x 1.4mm (Inner Diameter)
Assembly: Solder-type with screw-on shell
Will this fit into a standard 3.5mm headphone jack?
No. While the size is similar, DC power plugs are designed for electrical power transmission, whereas 3.5mm jacks are for audio. They are not cross-compatible.
Is this compatible with my Sony/Panasonic device?
Possibly. Many older portable devices from major brands used this specific 3.4mm standard. We recommend using a digital caliper to verify your device's port size before ordering.
Which terminal is Positive (+)?
While standard wiring often places Positive on the center pin (inner), some manufacturers use a "Center Negative" configuration. Always test your power source with a multimeter before soldering.
