I frequently have a video camera in a track car and would like to avoid the hassle of changing & charging batteries for it. The transformer block on the camera (Canon Elura) states the electrical output at 8.4v DC and 1.5a. In order to hardwire this to take advantage of my car's 12v electrical supply, I understand that a dc-dc converter is the best/only way to go. The solution will have to be secured, high G environment , and simple is key.

I found this which would seem to be perfect but know nothing about electricity and would like to know if a) it would work b) its 1.2a output instead of 1.5a might be a problem for the camera?

device details below & thanks for looking,

According to the website the optional voltage outputs allow for the 8.4v that you require. Since the unit has a rating of 1.2a max output you do run the risk of blowing the fuse that should be included with the unit. It truly depends upon the the fuse that is included with the unit AND what the internals of the unit can handle as a draw. I would definately give the manufacturer a call and see what they think about a 1.5a draw vs. a 1.2a draw.

Did a quick check of the website supplying the original product you mentioned. This item may fit the bill better:

Thank you for the suggestion. I looked around that site for a long time and those numbers, well, I didn't know which ones were important I'll call the mfgr today and get their thoughts.

Radio Shack has them.
