Is the food at the entrance different in the American NES, the Japanese Famicom and the Chinese Dendy?

Question

Electronics

Bought American and Japanese consoles from Nintendo. They have power supplies for their socket formats. You can use a transformer or pick up similar power supplies for our sockets. What should the output power supply produce to fit these consoles? Is the power supply from Dendy suitable, what are sold now?

Answer 1

What is written on the power supplies? Usually they write the face value of the day off.

Answer 2

Famikom and Dandy have 9VDC, NEC has 9VAC (it has a diode bridge in the console itself, and not in the power supply)
So yes, they should fit.
