How can 220 volts compete with 500 volts? Well maybe when the 500 volt eletric eel produces only 1 amperes while the 220 volt socket produces about 15 amperes. And the electric eel can only produce that for around 2 milliseconds, while the socket can produce that much pretty much infinitely. So 500 watts for 2 ms vs 3300 watts for indefinite amount of time? Of course the electric eel with 500 volts is the winner. Lolz
