What are some options for powering a Canon DSLR from 12V dc? The batteries don't last long at 40 deg. F and the Hutech adapter is poorly made and unreliable. Any body else making them?

You can buy such off the web, but curiously they are more expensive than if you make your own. You can make your own if you can find the part that goes into the camera (the false battery casing). That part is available from a cheap AC-Canon converter for your camera (available on some of the auction sites on the web). Simply cut off the part you need, plus the cable that goes to it. Connect that wire to the output of a transformer that puts out about 7.5 or 9 volts. They are available at car stores. THey have a 12 volt cigarette lighter male on one end, and wire coming out the other. Someplace they have a switch that allows them to choose 5, 6, 7.5, 9, and so volts. You may well already have one around the house.

Switch to output to 7.5. The Canons ask for 7.8, but will run on less. Be sure to match the positive and negative ends. The way you do that is to measure which part of the battery casing puts out positive, negative, etc.....and by how much. However you wire your converter, be sure that the readings coming off the battery replacement matches (within a volt or so) the output of the original battery.

Hi, Joe -- This may be the long way around but if you have a 12V to AC inverter you could use Canon's CA-PS700N AC adapter. It plugs into any AC outlet and its business end looks like a Canon battery. In my 1000D there's an exit port for its cable. -- works perfectly.
