Fervit USB 2.0 A Male to 5.5 x 2.5mm DC Barrel Cable 80cm

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.
