does the eGo passthrough from liberty flight work with the riva 510? It didn't say what it was/wasn't compatible but i'm pretty sure that they are almost identical devices. I got a new dc to usb adapter for my car so i can charge my ipod and stuff through the dc outlet, but i figured that would be awesome for a passthrough as well. Not only for just being able to use my pv in the car without worrying about batteries but if i accidentally drop it i have a wire to follow to find it haha. I've dropped my pv many a time in the car and struggled to find it
