The Sennheiser CHG2 US Charger is a dedicated power and charging station designed specifically for the company's Evolution Wireless G4 series microphone systems and select other professional wireless products. This unit functions as a centralized hub, allowing users to charge multiple battery packs simultaneously and efficiently manage their inventory of powered devices. It employs Sennheiser's proprietary charger cores, which are intelligently designed to communicate with the battery and optimize the charging cycle for safety and longevity. By providing a reliable and organized charging solution, it is an essential accessory for broadcast studios, touring sound engineers, and corporate AV departments that rely on consistent wireless microphone performance and need to ensure a ready supply of charged batteries.

This charger features a modular design centered around two included BA 2×15 V charging cores, which are the intelligent modules that physically house the batteries. The system is engineered to charge two AA-sized battery packs at a time, with each core operating independently. The intelligent charging circuitry monitors each battery individually, automatically switching to a trickle charge mode once full capacity is reached to prevent overcharging and preserve the health of the rechargeable cells. The compact and robust housing is designed for both rack-mount installation using optional hardware and standalone use on a tabletop, offering flexibility for various operational environments from fixed installations to mobile production cases.

Operationally, the CHG2 supports a wide input voltage range, making it suitable for global use with the appropriate power cord. Its design prioritizes clear visual status indication, typically through LED lights associated with each charger core, providing immediate feedback on charging progress and any potential faults. This charger is part of Sennheiser's ecosystem of professional audio accessories, built to the same durability standards as their microphones and wireless systems. It represents a professional-grade investment in workflow efficiency, reducing downtime and eliminating the waste and uncertainty associated with disposable batteries.
