DC 5.5 × 2.1 mm to Mini USB power adapter

This cable converts a 5.5 × 2.1 mm DC female jack into a Mini USB 5-pin male plug for 5 V charging. It is intended for users with a matching 5 V DC power source who need to power Mini USB devices. No data lines are connected, so the adapter cannot be used for file transfer or device syncing.

3 A at 5 V with 22 AWG conductors

The 22 AWG copper cores are rated for up to 3 A at 5 V, which is sufficient for most small 5 V peripherals such as Bluetooth speakers, MP3 players or desk fans. Drawing more than 3 A or connecting a 12 V source will exceed the cable rating and can damage the attached device.

Mini USB 5-pin power-only interface

The Mini USB connector supplies only the VBUS and ground pins, so the link carries no USB data signals. Any host expecting enumeration or communication will not recognise the connected device. The 20 cm length keeps voltage drop low but limits placement flexibility between the DC source and the device.

Questions about this item

Will this cable let me power a Mini USB device from my existing 5.5×2.1 mm DC power supply?

Yes, the DC 5.5×2.1 mm female input plugs into a 5 V adapter with that barrel size, and the Mini USB 5-pin male output delivers power to the device; it does not carry data.

How can I confirm the cable is delivering power correctly after connecting it?

The connected Mini USB device should power on or show its charging indicator; the cable itself has no status LEDs.

What comes in the pack and do I need any extra parts?

Two 20 cm black cables are included; you must supply a 5 V DC adapter with a 5.5×2.1 mm male plug.
