Power Adaptors / Famicom Power Supply

[nurd]

Okay, I'm going to make sure I find one that I know will work before I do anything.

On the back by the power hole, it says it needs a positive center.

Huh?

thanks for clarifying but im not going to find out

I just bought a FDS without a power adaptor (though they claim it's working) and I plan on getting some NiMH C cells. One less cord anyway.

Rechargeables are 1.25V unlike alkaline which are 1.5V, so instead of 9V they'll give 7.5V . If your FDS struggles to work, think about the batteries before anything else.

EDIT: Wrong number of batteries, thanks nurd!

similar to PONG.

it  needs six 1.5 volt AA batteries, or a 9V wall thing in a weird size.

[nurd]

is this the right thing?
I can't really tell from the description.

[kite200]

it is not the official adapter

[nurd]

But will it work as one?

Can i plug one end into the sharp twin famicom and the other end into the wall and then play it?

Famicom' s HVC-002 input is AC100V 50/60Hz 18VA, output: DC10V 850mA, polarity: + ------ C------- -

I am from Europe and here is 220V voltage. Famicom needs 10V 850mpA, and I have already Sega Megadrive 2 (US - Genesis), and it's adaptor is input: 230V ~ 50Hz, output: 10V 850mA 8.5VA, polarity:  - ----- C ------ +
Model MK-1636-18

As can be seen, the output  is the same, but I worry, that SEGA's adaptor is connected to 220V voltage net (Famicom should get power from 100-120V net), also polarity is different. But result is completely same: 10v 850mA.

May be someone have an advice to this situation, don't want to burn the console.. :]

hello slavco,

if you have a famicom adapter use a stepdown. thats enough.

Just found this articles:

There is written, that FC/SFC can be used with PAL Megadrive's adaptor.
Anyway I should buy step up voltage converter from 100V to 220V, to use console gently

That may only be the case for PAL (HK) Faicoms though. Get a stepdown converter to be safe.

If an adapter expects  the right power and outputs the right power, it will be fine.

You have to know what the adapter expects. If it expects 220 only, the output is only correct for 220. If it only expects 110, it only runs on 110. If it expects either, it should give the right output no matter what.

It's output needs to match too. The voltage can be a little higher than what you want and the ma can be higher also, but the center positive/negative does need to match. There is a lot of confusion about the center voltage in video games circles since the American NES doesn't care. But that's about the only system.

Neither of the 2 power adaptors you have are a match that will work. You will fry your system with either one (on 220).

As said get a stepdown and use the original adaptor. You could also modify the extra adapter to output the right polarity (simplest way is to cut the wire and splice it back with each wire going to the oposite--then you couldn't use it with the Megadrive). You can also find an ac adapter meant to work on 220 that does output correctly and has a tip that will fit.  My local thrift store has boxes of these on one shelf. That would be a good place to start.

i bought a universal power supply(?)
and it can deliver 9V or 12V - but not 10V

12V is too much right? but 9V?

[2A03]

9V is exactly the kind of voltage the stock Famicom PSU uses.

[133MHz]

Yeah 9 and 12V are ok, but respect the polarity! That's the most important thing. Remember the Fami is center negative.

[Scorp.ius]

9V is exactly the kind of voltage the stock Famicom PSU uses.

really? on my Famicom is printed 10V... thats why i was worried, but i will use 9V then

Thanks!
