The official AC-adapter is rated at 1.25 A, so 1 A might not be enough in all situations. For example If you are using lots of peripherals or flashcarts or so. Chances are that 1 A is enough though.

I mean how much power it needs varies depending your situation. If you run into unexpected behaviour it may be due to insufficient power.

My Famicom is ok with 1 A with the Everdrive and external controllers and stuff, so I do think it is enough.
The disk drive part also draws power when reading or writing disks though.

Here's the datasheet for the 7805 voltage regulator.

https://www.sparkfun.com/datasheets/Components/LM7805.pdf

It's rated to a minimum input voltage of 7V and a maximum of 25V.

No worries running at 9V, well within spec.

Twin Famicom does not have a 7805.

I've used mine for years with 9v without issue. The voltage regulators are designed to take 9V and drop it down to 5v.

If it's dropping it down to 5v, could you add a micro USB port in the back connected to the power points of the original plug if your old PSU goes out?

Itís possible but you wonít be able to run it from a computer most likely. You might be able to run it off a tablet charger

Just FYI, this readily available universal adapter from Walmart works perfectly with the Twin Famicom:
https://www.walmart.com/ip/Original-Power-Powerline-1300-mA-Universal-AC-Adapter/16778839

Just use the "biggest" (largest inner diameter) barrel, set the voltage to 7.5v, and flip the polarity switch to center positive, and you're golden.  The barrel inserts with a nice click, and the 1300mA current is ample and stable.
