I cannot obtain a power cable to enable use of this socket. However I do have a transformer which has various DC outputs one of which is 3v.It also has a number of plugs one of which fits the socket on the camera. Can you tell me if the plug tip is Positive or Negative.
I have had this excellent camera for quite some time, and a power supply would be useful when in use for long periods i.e. on a PC.
Hope you can help, and any advice would be appreciated.
Happy New Year
I have not found a solution to the problem. I did reply to your last message and said I would not bother because I can manage with batteries. I cannot see why I cannot use my transformer which has a stabilised output, how can it damage my camera. All I wanted to know was is the tip Positive or Negative on the power input to the camera.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Your Pentax K7 lacks firewire (1394) connectivity, so a connection to a fireware jack will not be possible without purchasing an inexpensive Firewire to USB adapter . From the manual:
USB 2.0 hi-speed, AV out, HDMI out, DC in, cable switch, 3.5mm stereo microphone.
Video out: HD (1080i30, 720p30, 480p30), NTSC, PAL
Printer interfaces: n/a
The I/O (input /output) panel on a Pentax K7 camera.
You can connect a USB cable from the "PC/AV" on the camera to your computer's USB port with an appropriate cable to transfer image files for editing, etc. Additionally, you can send video directly to a TV with an appropriate cable via the camera's HDMI jack.
If this camera is like my FZ20, there is a socket to provide power to the camera from a mains adapter. The input socket is under the cover where the USB lead goes, and the manual shows a lead attached between this and a battery charger. My battery charger does not have this lead or DC output, though. The one that does is an optional extra, part DMW-CAC1. The manual recommends using the adapter to power the camera when it is connected to a computer, to make sure that a flat battery doesn't cause the memory to become corrupted.
My suggestion is that you attempt to power the camera through this DC power input, either with the approved adapter (maybe one of the chargers you are using has the output?) or with a generic one. I have successfully used a generic 9 volt adapter on my camera (positive center connector).
If it will power up with an adapter, I expect there is an issue with the connections in the battery housing. Otherwise, it might be a more fundamental fault.
Kodak has 3 types of charger that can be connected to a wall socket USB AC Adapter - is especially useful when traveling, away from your computer, or just plain on-the-go. Connect your camera's USB cable to the adapter and plug it into a wall outlet to conveniently charge your camera. 5V AC Adapter - Provides in-camera charging for all KODAK EASYSHARE M and V Series Digital Cameras Input: AC 100-240 V 50/60 Hz Output : DC 5.0 V 3V AC Adapter - Provides direct power to your camera but it will not charge the camera battery Input: AC 100-240 V 50/60 Hz Output : DC 3.0 V
* You need to check the type of adapter your using. If your using the 5V AC adapter or USB adapter and the camera won't charge the battery contact kodak support line 1 800 235 6325 (23KODAK) for possible repair.
The polarity is correct, but 400mA is not enough. One commercial supply I saw was rated at 2.5A. I even suspect 3v isn't enough as I have tried an external battery pack with D-Cells in it and after a few flash shots it wants new batteries. The camera itself seems to be over-sensitive to "low" voltage and complains about new or freshly charged batteries (see other posts).
There is a problem with these cameras in this battery voltage area. I have asked Vivitar what external voltage to use, but no reply. Good luck! I am sufficiently fed up with this camera that I may try 4.5v external supply and if it blows up, good riddance!
Charge the batteries by plugging any 5 volt (1.5 or 2 amp output) transformer directly into the side of the camera. Many Fuji transformers have the same plug as well as some old Kodaks and Ricohs; and I have also used the charging transformer/cables from my TomTom GPS (home and auto) to re-charge various Porsche-design Fujis and equivalent Leica Digilux cameras.
The T is the thermister that the battery charger uses to determine the battery temperature and make sure it's not being damaged by high temperatures, you can safely ignore it when you hook up an external supply, it won't cause any errors on the camera or anything.
If you want to hook up a DC adapter to your camera just make sure it's a well regulated (a switching power supply should be just fine, like a wall adapter only they're typically much lighter weight but adapt AC to DC) and is the correct voltage. The reason I recommend a switching power supply is that traditional wall transformers only provide the rated voltage at rated load, meaning if you hook up a 12VDC 2A wall adapter to something that draws 1/2A it will have a significantly higher voltage that it has stamped on its case.
if the power socket is a normal socket like a nokia phone charger you might be able to get a universal variable volt adaptor. i got one for my base station for my ipod as i lost the mains adaptor. bought it from Argos though im sure there are other stores that sell the same or similar.
If you are thinking of runnig it from the mains supply then you will need a 3v units - a common universal unit from will do it
the camera will have a diode thats protects the polarity and a universal power supply with have reversible connectors
