I have lots of gadgets. Tablets, phones, etc. I'm looking for a wall charger that will charge multiple devices (Prefer 4 or more) via USB, at the 2A speed, all at the same time. I have seen many devices that have many ports, but usually only 1 port is 2A, or the total is 2A, and that is divided by how many things are plugged in, etc. I can't find anything that charges everything at 2A, all at the same time. Anyone know of such a thing?
