    So I have an interesting (maybe stupid) question. I have an android phone charger, an ipod charger/radio broadcaster, and an audio broadcaster. This is too many damn cables in my car, and I only have one 12V port that works. I got this crazy idea to have them all share this port. Is it possible to wire all three of these devices together so they all share one car plug so I can use the one port and all three devices? Thanks for any help

    I presume you're referring to a single lighter plug?

    If so, yes, you can wire all of the 12V electronics to a single plug. It is very unlikely that they will draw more than the 10A or so you can draw from the lighter socket :)

    You can't just blindly use one "charger" to power them all because they may have different voltage requirements and it is not certain that any one of the adapters can power all three devices.
