See my DPS-8000 review as the DPS-4000 has been discontinued and is no longer available.
I put a small piece of electrical
tape over the cord to firmly attach it to the front of the camera, cord
problem solved -- just remember that plastic door is sticking out. On other
types of digicams where the power connector is on the side or back it
will not be much of a problem.
OK, enough techno-babble already, how does the thing work?
To begin with I just plugged it into the Nikon 900, turned it on the A-Rec position so that the LCD was on and the autofocus was buzzing back and forth and just let it sit until it died. It ran for an hour and thirty-five minutes. Charged it up again (8 hours) and then went outside and started shooting everything I saw. I put the camera in VGA (640x480) economy mode with a 45MB card and the counter said I could take 999 pictures. I got to 425 pictures before my shutter finger wore out and the battery pack was still going strong. (And my Nikon was quite warm to the touch.)
Later indoors using the flash I shot another 43 pictures before the camera finally died. If this was a real-life shooting situation all you need to do now is unplug the DPS 4000 and go on shooting with the regular batteries inside the camera.
The DPS 4000 is rated at 1200mAh and I asked the Mizco folks if they could make it a little heftier. Stefan Guelpen said that they were thinking about making a 2400mAh version using lithium ion cells which are smaller.
12/7/99 update: Well, the Mizco folks have built a much heftier
NiMH pack now, the DPS-8000 features 2700 mAH
worth of 4.8v NiMH cells and it costs less than the original DPS-4000!
It would have been a 5 if it was a little larger capacity but all in all it is still a nice, small, external battery pack that doesn't cost an arm and a leg and gives you plenty of picture taking power.
See my new DPS-8000 user review, this pack is bigger and more powerful and gets a 5 digicam rating!
