The Shure SBC203 is a dual-docking recharging station specifically designed to charge both SB903 rechargeable batteries and SLX-D series wireless transmitters simultaneously. This all-in-one station streamlines the power management workflow for users of Shure's SLXD digital wireless systems. It features two dedicated bays: one for charging an SB903 lithium-ion battery and another for docking and charging an SLXD1 or SLXD2 transmitter (when used with an optional charging door). This integrated approach ensures that a performer's entire wireless rig—transmitter and battery—can be charged and stored together in an organized, compact unit.

The charger utilizes intelligent circuitry to charge both the battery and transmitter safely and efficiently, employing algorithms that help extend battery life over many charge cycles. LED indicators provide clear status for each bay, showing charging progress or completion. The SBC203 requires an external power supply (sold separately) and has a compact, desktop-friendly design. For touring musicians, presenters, or churches, this station simplifies the pre-show routine, guaranteeing that transmitters are fully charged and ready to go with a fresh battery installed, thereby eliminating the risk of show-time failures due to depleted disposable batteries or forgotten charging.

By promoting the use of rechargeable batteries and providing a centralized charging hub, the SBC203 supports a more sustainable and reliable operational model. It reduces waste from disposable batteries, cuts long-term costs, and ensures consistent performance by always providing a fully charged power source for critical wireless equipment.
