Is this a feasible product? Charger for multiple different devices

Hey folks,

I was thinking about it and I wonder how feasible it would be to have a device that is used as a laptop charger but has some extra ports on the side in order to plug in your phone, ipod, etc.

This could be similar to the Anker products for your car and is partially where the idea came from. Rather than the charger acting as a battery for later, however, it would just act as a normal charger so it still needs to be plugged in. Obviously Anker needs to get into a universal-type charger first unless they want to make an addon for existing chargers. But I could see this being important since a lot of people with their laptops charge their phones as well like at Starbucks, Library, etc. and you could keep everything in one outlet.
