Watson Duo LCD Charger for L & M Series Rechargeable Batteries

The Duo LCD Charger for L & M Series Batteries from Watson conveniently charges two batteries simultaneously, drawing power from either an AC wall source (an AC cord with two-prong plug is included) or a 12/24V DC power source (a DC car charger is also included). Additionally, the Duo Charger features a USB power output that supports up to a 2A draw to charge and power smartphones, digital cameras, and other devices with a USB power input.

The interchangeable battery plate system allows you to charge other camcorder-type batteries by swapping out the included plates for different camera plates (not included). The intelligent charger features an LCD screen that graphically shows charge status for both batteries. The charger also features a test button that allows you to test batteries when the unit is not plugged into power, to see their remaining power as a percentage of their capacity. The test button will also switch the display between battery capacity and charging voltage.

Dual-Bay Charger
Charge two batteries simultaneously and independently. This allows you to charge two batteries with different capacities or charge status at the same time.
LCD Display
The LCD screen shows charging status and charging voltage, as well as the voltage for car and USB charging.
USB Output
The charger has a built-in USB port that outputs 5 VDC at up to 2A, allowing you to power and charge mobile phones, digital cameras, and other related devices with a USB power input, even while you're charging your digital camera or camcorder batteries.
Test Button
Test the charge of a battery even with the Duo Charger unplugged by sliding the battery into the charging plate and pressing the test button. Press the button a second time to display the voltage of the battery.
Safety Features
Short-circuit protection, overcharge protection, and overheat protection.
Compatibility
Sony NP-F550, NP-F570, NP-F730H, NP-F750, NP-F770, NP-F930, NP-F950, NP-F960, NP-F970, NP-FM30, NP-FM50, NP-FM500H, NP-FM55H, NP-FM70, NP-FM90, NP-FM91, NP-QM71, NP-QM71D, NP-QM91, and NP-QM91D type
