The Dolgin Engineering TC-400 Charger for Sony NP L / PD170 / VX2100 Batteries is a microprocessor-based battery charger that provides fast and safe simultaneous charging of Sony NP L series batteries and the batteries that come with Sony's PD170 and VX2100 cameras. The charger features an LCD display that indicates charge status and true capacity upon charge completion. True capacity is determined by a built-in Test/Discharge module in the charger. The module cycles a battery through a charge-discharge-charge process to test the battery's capacity.
A 100-240V AC power supply is included.
