Dual Battery Capability: Charge two Nikon EN-EL9 batteries at the same time on the dual universal charger without increasing the charge time for either battery. Each battery is monitored and controlled individually on a separate circuit, so it operates like two high-end battery chargers plugged in side by side. No more waiting around until your first battery charge is complete before plugging in your backup! (NOTE: This model includes two plates for Nikon EN-El9 batteries to be used with the Dual Universal Charger which needs to be purchased separately. Additional plates for charging other batteries, including one for 4 AA battteries, are sold separately).
Universally Compatible & Expandable: Battery charging plates are designed specifically for each digital camera battery model. Purchase only the charging plates that you need, and add on additional model capabilities at any time. Unlike confusing multi-model charging plates that are packaged with most universal battery chargers, this single-model charging plates are simple to use and easy to slide on and off.
Quick & Efficient Charge: One of the most unique characteristics of rechargeable lithium-ion battery is that they cannot be "quick charged? like other rechargeable batteries. Rather, most digital camera batteries require what's called a "constant current / constant voltage? charge until charging is complete. Because lithium-ion chemistry is so efficient, even a high power digital camera battery charges quickly in standard chargers. The Delkin Power Dual Universal Battery charger uses similar charging methodology as your original equipment manufacturer, ensuring a quick and efficient charge every time.
Know Your Power: LED gauges on each side of the charger accurately report individual battery charge status in real time as charging is underway. Know when your battery is 25%, 50%, 75% or 100% charged with just a glance.
Travel the World: Automatic 110/220V switching allows you to take your charger with you on all of your adventures. No confusing switches, toggles, or complicated user manuals to decipher. For charging on the go, a car charger is included with every Dual Universal Battery Charger.
