USB-to-DC power cable for portable devices

This 1.2 metre cable converts a standard USB-A port into a 2.5 x 0.7 mm DC barrel plug. It lets you run or charge small electronics that expect a 5 V supply from any USB 1.0, 1.1 or 2.0 host. The compact moulded connectors suit tablet PCs and similar gear with a matching jack.

Replaces bulky wall warts for mobile use

Swap a fixed mains adapter for this lightweight lead when you have a free USB socket on a laptop, power bank or hub. The change is worthwhile if the device draws within the host port’s current limit and you want one less outlet occupied. It does not suit equipment needing higher voltage or a larger barrel size.

Steady output within USB current limits

Under continuous load the cable simply passes whatever current the USB host allows, so performance stays consistent as long as the source maintains its rated output. There is no active regulation or voltage conversion inside the plug. Extended runs at the host’s maximum may warm the connectors slightly.
