USB 2.0 to DC 5.5x2.1mm adapter pair

This two-piece set converts a standard USB 2.0 Type-A port into a 5.5 mm by 2.1 mm DC barrel jack. Each adapter accepts 5 V input from the USB host and passes it through the female connector. The assembly is rated for up to 3 A, giving a maximum of 15 W.

Plug-and-play power for 5 V barrel devices

The male Type-A plug inserts directly into any USB-A socket on a laptop, power bank, charger or similar host. No drivers or configuration are required. The compact moulded body keeps the connection secure while adding minimal bulk to the host port.

Ideal for 5 V routers, fans and small monitors

Buyers powering 5 V networking gear, desk lamps, portable displays or audio devices from a USB-A source will find this a direct fit. It cannot supply 9 V or 12 V, so equipment requiring higher barrel voltages must use a different solution.

Questions about this item

How much power can the 5.5x2.1mm DC connector draw from a USB 2.0 port before it hits its limit?

The adapter is rated for a maximum of 5V at 3A, which equals 15W. It only works with a 5V source and cannot accept 9V to 12V input.

Does the adapter get warm or make noise when powering a device continuously at the 15W limit?

It has no fan or active cooling, so it runs silently. Warmth will depend on the load and the host port, but the unit itself adds no moving parts or audible noise.

What must the host device provide for this adapter to function correctly?

The host must supply a standard USB 2.0 Type-A port that outputs exactly 5V and can deliver up to 3A of current for the adapter to operate within its 15W rating.
