I'm working on a custom charging station rack which would allow me to charge 3 of my tablets simultaneously. I already have the rack and adapters setup for the tablets but it requires 3 different outlet plugs. I am looking into combining these into a single plug by wiring each adapter in parallel with the wall outlet. I never have strayed far from battery and microcontroller power sources before so in my mind household power is no different but surely the 120V is nothing to scuff with so my confidence is weary.
Would running multiple adapters in parallel actually work as I expect it? What would then be the best path to achieve this? What about if I ever want to extend to more devices? Any regulations or additional safety precautions for the circuit?
I live in the US and two of the adapters are the standard 5V-2A transformer, the other one is also not far off.
