Digital Cameras Photo Reviews of Coby IC Regulated 800mA Universal DC Car Converter CA709
Customer Review: maybe ok for low current btty powered items.
Summary: 2 Stars
I bought this to substitute for batteries (2AA) for a small low current device in my car. I read the various negative reviews and they sounded as if people were using it for devices that exceeded its abilities. Turns out there are other issues besides limited current capacity. When I started using it there would be random losses of power. I found that the center contact is not designed correctly. It bottoms out in the plastic housing, so when pushed in it can easily lose contact intermittently, then get it back. Not good for use in a car. I modified the contact so it behaved more like better CLAs and things improved considerably but there were still random losses of power.
I continued to play around with it using a 12V DC brick that had has a CLA socket as it's output. I could not reproduce the problem when everything is sitting still. The connections I made to connect the coby to the camera seem solid and work just fine in the car using a remote battery pack instead of the coby. I am still unsure what is wrong with it, perhaps I was unable to improve the center contact enough or there is something inside that doesn't like the vibrations of driving. It works nice sitting still at home plugged into the brick, just won't work that well in a moving car.
If I decide to go further I'll probably modify it by wiring it to one of my better CLAs. This will eliminate the CLA part of it from use and I'll find out if it's just a mechanical contact issue or something in the underlying electronics.
