The VL-2X 2-Channel V-Mount Charger & Power Supply from IDX provides sequential charging for lithium-ion and NiCad batteries, automatically switching to the second battery after fully charging the first. It delivers up to 2.7A of quick-charge current without the noise of a typical charger thanks to a fanless design. It also features a 4-pin XLR power output that offers up to 36W of DC power when the charger is connected to a wall outlet and your batteries are removed. (The DC output is disabled when a battery is charging.)
