USB 2.0 A to 5.5 x 2.5 mm barrel cable
This cable draws 5 V DC from a standard USB 2.0 Type-A port and delivers it through a 5.5 mm outer, 2.5 mm inner barrel plug. It is intended for small electronics that accept power through that specific jack. The 80 cm length gives enough reach for desk or bench use without excess slack. No separate power supply is required.
Replaces a dedicated 5 V wall wart
The cable lets you run a compatible device from any powered USB port — computer, hub or charger — instead of a proprietary AC adapter. The jump is worth it when you want to reduce the number of mains plugs on a power strip or need a portable power option for field testing. It only works where the device draws within the current the host port can supply.
Handles low-power 5 V gear up to host limits
The cable comfortably powers routers, LED strips, Arduino boards and similar 5 V equipment that uses the 5.5 x 2.5 mm connector. It runs out when the device demands more current than the USB port provides or when the barrel polarity or dimensions differ from the 5.5 mm by 2.5 mm standard. Check the device label before connecting.

Questions about this item
Will the 5.5 x 2.5mm barrel connector fit my device's power jack?
The cable ends in a 5.5mm outer diameter and 2.5mm inner diameter barrel plug, which matches the common 5.5 x 2.5mm DC power input found on many small electronics.
How do I connect this cable to supply power from a USB port?
Plug the USB 2.0 Type-A male end into any standard USB-A port that delivers 5V, then insert the 5.5 x 2.5mm barrel plug into the device's DC power jack; the cable draws power directly from the USB port without drivers.
How durable is the 80cm cable for daily use and when might it need replacing?
The 80cm length reduces strain on both connectors during normal use; replace the cable if the barrel plug becomes loose in the jack, the USB-A shell wobbles in the port, or the insulation shows cuts or exposed wires.
