The JBL EONONECOMPACT-5V9V is a specialized USB power cable designed to bridge the power needs of the JBL EON ONE Compact portable PA system and the AKG DMS100/300 digital wireless systems. This 1-meter (3.28 ft) cable features a USB-A connector on one end and a 5.5mm DC barrel terminal on the other, allowing users to draw power directly from the PA speaker's high-power USB ports. It is engineered with an internal voltage booster that efficiently converts the 5V USB output from the speaker into the steady 9V DC required to run a wireless receiver or even select DigiTech-DOD guitar pedals.

By utilizing this cable, performers like buskers, mobile DJs, and presenters can operate an entirely wireless setup without needing an external AC outlet or separate batteries for their microphone receiver. It delivers up to 1300mA of output current, ensuring a stable and reliable connection that maintains the high-fidelity 24-bit/48kHz audio quality of the AKG DMS series. This "off-grid" capability, combined with the EON ONE Compact's 12-hour battery life, provides a truly portable solution for professional-grade live sound in any environment.
