Williams AV OC-20 Ovation Charger Stand

The Williams AV OC-20 is a trio-well drop-in charging station designed for seamless and reliable charging of your Ovation wireless microphones. It provides USB-powered docking for one handheld (OM-20) and up to two pendant (OM-10) microphones, with precise-fit wells and a microprocessor-controlled charging timer that extends battery longevity while keeping gear classroom-ready.

The charger features a glossy white housing with four built-in magnets for mounting on ferrous surfaces—such as the OA-50 amplifier—and includes four rubber pads for stable placement on non-metallic surfaces. The controlled charging schedule aligns with the microphones’ on-board auto-shutdown routines, helping to optimize battery health over long periods of inactivity.
