what makes you say that? I'm curious not challenging LOL
There is no reason you can't install an inverter that would take care of small electronics.
First you can use the power port, aftermarket makers sell inverters that plug right into the power port, these should run small items maybe even a drill.
Or you can run a wire right from the battery to an inverter, but with this type you take the chance of running down your battery because it will invert power without the car running.
I would recommend installing an inverter that can only be used when the car is running, there is less chance of you becoming stranded with a dead battery.
