USB-to-DC dual-tip internal power cable

This internal power cable connects a USB source to devices that accept a 5.5×2.1 mm or 3.5×1.35 mm DC barrel jack. The 0.3 m length suits tight routing inside enclosures or small-form-factor builds. It targets users powering routers, hubs or single-board computers from a USB port or power bank.

Straightforward fit with polarity caution

The two moulded tips plug directly into the matching barrel sockets without tools or adapters. The short run leaves little slack so verify the exact jack size and centre-positive polarity before ordering. Builders needing a longer reach or a locking connector will need a different cable.

Questions about this item

How can I confirm the cable is delivering power correctly after connecting the USB end and the 5.5×2.1mm DC plug?

The connected device should power on and operate normally; the cable supports 5 V at up to 3 A, so any compatible 5 V equipment within that current limit will start without error.

Which connectors are included on the cable and do I need any extra adapters for the 3.5×1.35mm jack?

The 0.3 m cable has a USB-A plug on one end and a dual DC head with both 5.5×2.1mm and 3.5×1.35mm (5521) barrels on the other; no separate adapters are required for either size.
