Excerpt: I reluctantly ordered this charger to go along with the Nikon EN-EL4a battery that I purchased at the same time. After receiving the order and using it to fully charge the EN-EL4a to full capacity from a 50% level I was surprised by how quickly the process completed.
Excerpt: Great product and a smaller alternative for charging my D3 batteries. Nice that Nikon offers two chargers for their batteries. I have the larger two battery charger and it's great but when I'm traveling, every bit of space and weight counts, so this is perfect for my purposes.
