Query: Compact, sturdy

This is great for travel. It definitely beats the clunky Nikon battery charger complete with a bulky cord that came in the accessory pack to my Nikon Coolpix camera. I can charge the Nikon batteries in this (doesn't have to be Sony) - I like that I can charge four at a time and keep a 3rd set in my camera at the same time. The plug folds back into the unit for easy travel, and the indicator light lets you know when the batteries are charged. Well worth the money.
