I ordered a used version of this charger through the Adorama used department, it arrived quickly, but was defective. I sent it back, ordered a new version which had very obviously been used, there were scrapes all over the charger and the box was very beat up. Customere service had someone in the retail store pull one off the shelf to make sure that the 3rd one was perfect. It was. My big complaint was that I had my credit card tied up with the purchse of 3 chargers but only wanted one!
Only one battery charge at a time, this charger is rock solid just like the the one that came with my Nikon but I can charge two batteries.
I use it because i need to be free from electrical network.
