Toyota Camry Hybrid tech question

This is a low current device and could be run directly from the battery. Remember, anything constantly running like this will eventually drain the battery. Hopefully the current draw will not exceed your battery capacity.

If you choose to run off the 12 volt battery, just hook up a battery tender to maintain the battery. Otherwise, and my recommendation, would be to get a 12 volt converter that plugs into house current and nests next to your car. Then you may run 12 volt devices off that..... Mouse repellers are notorious failures; cheap ones never work. If you get a decent one, it can rest under the car and be plugged into the alternate 12 volt power source.

Thanks for the help, folks. I Iike the idea of the separately powered mouse repeller. I have a 110 plug nearby. Such a repeller doesn't need to ride along with the car. What I was curious about is if there's any place under the hood where I can pick up the 12 volts from the battery directly. Trying to draw it out of the fuse box (although I had no problem finding the voltage) turned out to be a bad and expensive idea ... a little embarrassing as well. The electronics are apparently too delicately balanced to tolerate an unexpected load at an unexpected place. This isn't a 1950s Chevy Nomad.
