Watson Duo LCD Charger with Two EN-EL15 Battery Plates

This Duo LCD Charger from Watson restores power to one or two EN-EL15 EN-EL15 batteries via the included, dedicated plates. These can be replaced by optional plates for various other batteries. Additionally, the Duo can simultaneously charge two different batteries with different voltages. Charging time is between two and six hours. The unit also features a USB 2.0 port, which allows you to charge and power a mobile device while your camera batteries are being replenished. The LCD screen displays each battery's charge percentage--even when the Duo is unplugged--via the test button.
