Audio-Technica ATW-CHGA6 Single/External Battery Charger

The ATW-CHGA6 charges a D50 lithium-ion battery on its own, outside a transmitter, which is the accessory a touring rig or a house of worship keeps on hand once it starts carrying spares. Drop in an LI-220 or LI-320 pack between shows and it comes back charged without tying up a transmitter dock.

It is a companion to the ATW-CHG6 and ATW-CHG7 charging stations rather than a replacement for them: those dock the transmitter itself, while the CHGA6 exists purely to keep loose battery packs topped off and ready to swap in when a show can't wait for a full transmitter recharge cycle.
