The Sony BC-ZD1 Dual Battery Charger rapidly charges NP-FZ100 batteries simultaneously when connected to a USB PD power supply. It offers a fast 155-minute (approx.) charging time for two battery packs and features LED indicators that display the charge status of each battery independently in five steps. The charger has a flat, low-profile compact design measuring just 84.5 x 29.2 x 70.0 mm and weighing 149 g. Please note that NP-FZ100 batteries, a USB PD compatible power supply, and a USB cable are not included. Simultaneous two-battery charging requires a USB PD (30 W min.) compatible power and cable (3 A min.).
