I routinely put all my electronics (cell phones, CD players, DVD players, cameras, video cameras) all in the same large zip-loc bag. It's clear, so the agents can see what's in there. I take it out of my carryon bag, and send it through in one of the plastic bins on it's own. Then, back into the carryon at the end of the conveyor belt. When we get to the gate, and sit down, I can sort all the electronics to the appropriate people!
