The D-DC128 DC Coupler from Pentax is designed for select Pentax DSLR cameras which use the D-Li109 battery. When paired with the D-AC120 AC Adapter, it can supply your camera with uninterrupted power for extended periods of time, without worrying about draining the battery power. This time can include downloading pictures to your computer, for extended work in a studio, or while viewing images when connected to your TV.
It is cautioned that you ensure the camera is turned off before connecting or disconnecting the AC adapter. Make sure connections are secure between the terminals. SD Memory Card or data may be corrupted if the connection to the power supply is lost while the card is being accessed.
