Frequently Asked Questions
Q: Can I use this to power two devices at the same time?
A: Yes — the female jack connects to your power supply, and the two male plugs connect to your devices. Ensure your power supply can handle the combined current draw of both devices.
Q: What connector size does this use?
A: All three connectors are 2.1mm (inner diameter) x 5.5mm (outer diameter) — the most common DC barrel connector size.
Q: Is the polarity center positive?
A: Yes. This cable follows the standard center-positive convention. Verify your devices' polarity before use.
Q: What wire gauge is used?
A: 18 AWG — suitable for most low-voltage DC power applications up to a few amps per branch.
