Powering 5 V DC Gear from a USB Port

This two-pack of cables lets you draw 5 V DC power from any standard USB 2.0 Type-A port to run small electronics that use a 5.5 mm by 2.5 mm barrel jack with centre-positive polarity. Each cable is three feet long and rated for up to 2.5 A, making it handy for portable hard drives, routers or other low-voltage peripherals when a wall adapter is not convenient.

Build Quality and Everyday Use

The conductors are copper and the connectors are moulded with strain relief to withstand repeated plugging and unplugging. A USB Type-A male plug goes into the host while a 5.5 mm outer, 2.5 mm inner male barrel plug mates with the device, so there are no loose adapters to lose. The black jacket is flexible enough for travel bags yet robust enough for permanent desk setups.

Limits of the USB 2.0 Interface

Because the source is a USB 2.0 port, the cable cannot deliver more current than the host allows, and many ports limit output well below the cable’s 2.5 A rating. Voltage drop over the three-foot length also becomes noticeable at higher loads, so devices that need sustained peak current may not start reliably. Buyers who need more power or a different barrel size cannot use this cable.

Questions about this item

What USB standard does the cable use and what current limit applies?

The cable uses USB 2.0 and supports a maximum of 2.5 amperes.

What are the exact barrel dimensions and polarity for a secure fit?

The barrel connector measures 5.5 mm outer diameter by 2.5 mm inner diameter with a positive centre pin.

How is the cable connected and what common mistake should be avoided?

Plug the USB Type A male end into a host port and the 5.5 x 2.5 mm barrel into the device; verify the device requires 5 V DC and the same barrel size before connecting.
