Overview

The Sennheiser 508862 is a dedicated charging set designed for the EW-D digital wireless microphone system. It pairs the L 70 USB charger with two BA 70 rechargeable NiMH battery packs, giving EW-D transmitter users a sustainable power solution that eliminates the recurring cost and waste of disposable batteries. The USB-powered charger can accommodate both packs simultaneously, allowing you to maintain a rotation where one set powers your transmitter while the other charges — a practical workflow for live events, houses of worship, and production environments with back-to-back sessions.

The compact form factor of both the charger and battery packs makes the set easy to add to an existing gear bag alongside your EW-D transmitters and receivers. Because the charger draws power via USB, it can be connected to wall adapters, laptop ports, or portable power banks, offering flexibility in how and where you recharge. While the set is strictly an accessory — no wireless audio components are included — it fills an essential role in keeping an EW-D system reliably powered for extended or repeated use.
