There is nothing more embarrassing than a transmitter running out of juice in the middle of the show, or a voice fading as the transmitter battery dies. The CU 400 charging unit puts an end to this kind of hassle. It can charge two batteries simultaneously to full capacity within one hour, and there is no risk of overcharging the batteries. With no need to remove the battery from the transmitter. A single 1.2 V NiMH AA size battery (> 2000 mAh) provides up to 8 hours of operation.

The CU 400 has been designed specifically for use with the WMS 400 system.
