Use the CP-95 Coupler with the AC-5VX Power Adaptor (supplied separately) to power your camera directly from the mains. The coupler simply slots into the battery compartment after the battery is removed and ensures that power is supplied constantly to the camera. This is of key importance when downloading images from the camera to ensure no loss of power occurs should the battery run out of charge. The CP-95 Coupler only provides power to the camera and does not charge the battery.
