Rapid Sony Charging. Charge up to two Sony NP-FZ100, NP-FW50, and NP-BX1 batteries in just 1.5 hours with this Watson DuoVolt Charger for Sony! With two charging speeds, you can opt for low-voltage 2.5 hour charging to preserve your battery life, or opt for high-voltage 1.5 hour charging to keep things rolling.

Batteries and Display. Not only can you charge two of the same battery simultaneously, this charging system allows you to charge any combination of the three! You can also enable the Battery Heath function to check how well your batteries are performing, and with the press of a button, the LCD screen on the DuoVolt displays useful battery information, like temperature, charging modes, and battery percentages. Please note that the Sony NP-BX1 will need to be inserted upside down in order to charge!

Additional Features. To prevent a decrease in battery performance, this charging system automatically detects when currents are exceeding battery limits, and will perform a safety cutoff feature that will prevent the system from overheating or damaging your batteries. After 5 minutes of inactivity, the DuoVolt enters Standby Mode until a button is pressed or a battery is inserted. When you’re away from a power source, you can still insert a battery and check its fuel percentage!
