Query: Check your DSC-W55's battery type before ordering this adaptor!

Warning: The AC-LS5K adapter does NOT work with the Sony Cybershot DSC W55 camera if the DSC W55 uses a square Lithium Ion battery. Neither of the two plug-ins on the adaptor can be plugged into the camera anywhere! The adaptor is designed to plug into a battery chamber for two AA batteries, but the smaller chamber for the square Lithium Ion battery will not receive the adaptor. If your DSC W55 uses two AA batteries, this adaptor is fine.
