2A 5VDC 11W charger

Using super diodes (In theory, an almost perfect one way conductor, dropping only 20mV but pushing 2.17A, with 0F of capacitance, 1mOhm resistance, and 10uA saturation current)
Using pulsated DC because at 120Hz the device should stay charging and it saves on the capacitor power draw issue

what the heck is a super diode

A super diode as he calls it os just a regular diode with a very small forward voltage drop. This diode activates at 20mV as opposed to normal diodes that start conducting at 300-700mV. It's what you'd know as a shotkey diode or more likely a tunnel diode.

what's the part number of a super diode? these 1N5819 diodes are Vf 200mV at 100mA but 600mV at 1A

The part number for these probably don't exist to be honest

a relay is better.. mechanical switches have zero V drop during 'ON" state and when half wave synchronically operated they sounds so sexy doing cling,cling,cling,bzzzzz,cling that's a supa mechano'o'diodo i tell ya

Well, find me the relays then Sec! :p
