This adapter power cable draws standard 5V power from any USB 2.0 Type A port and outputs power via a common 5.5mm outer diameter × 2.1mm inner diameter DC female barrel socket. It eliminates the need for dedicated DC wall adapters for small low-power electronics, letting you conveniently power DC fans, miniature speakers, small LED lighting modules and other DIY low-current equipment through USB power sources.
