I lost the AC adapter for my NES, but this one fits. I mean, the plug goes into the NES nicely, but will it work?

I don't know how electricity works, those numbers don't tell me much.

Oh, and also another question: may it work on a Super Nintendo?
I know the plug won't fit, because the Super NES needs a slightly fatter plug, plus the voltage required by both consoles is not the same, but I'm curious because I know these machines aren't too picky about such things.

Sage because double-post.

I run my NES off a 12v @800mA adapter I have lying around. I don't think you'll break anything, but neither do I know if it will work.

The SNES is actually super fucking picky when it comes to where it gets its power from.
Use an unofficial adapter and you'll get funky colors and random resets or sound glitches.

Source: Went through 3 AC adapters for my SNES before I finally said fuck it and bought a legit one from some bullshit retro store.

7V is not really up to task for powering the NES.

The NES AC adapter converts 120V AC to 9V AC. Yes, AC, not DC. There is a rectifier in the NES itself that converts the AC waveform to DC, but you can use any 9-10V DC adapter with the NES without issue, including the Sega Genesis 1/Sega Master System AC adapter. The official NES AC plug is listed at 1.5A, but I haven't checked to see if the system actually draws that much current at any time.

I wonder why they did this.
But yes, this is also the reason why you should never use an NES power brick on a Famicom and viceversa.

Show both adapters.

why?
were they using the power frequency as some kind of timing signal?
and is the snes the same?

Doesn't seem that way. Pics related.

Technically you can feed DC trough the rectifier in the NES without a problem, the schematics i found shows 13V DC getting made into 5V.
So i would say you could use the 7.5V you have there.

But please don't blame me if you kill your NES
