The hahnel Professional Charger PROCUBE2 for Select Nikon Batteries is a 2-bay charger that is compatible with the EN-EL14 and EN-EL15 batteries and can charge one or two lithium-ion batteries within 100 minutes simultaneously. An included charging plate, which sits atop the existing plate, charges four NiMH batteries as well.
To replace an interchangeable charging plate there is no need to plug or unplug any wires. To remove, use the plate eject tool on the side of the charger, and simply pop-in the new plate. Once all the batteries are in place, the easy-to view LCD display shows the charge status, health check, and the capacity of mAh being added to the battery. In addition, an integrated USB port will charge numerous devices supported by this connection.
