power adapter US and international swap?

In 3rd photo, both cables are 2.5Amp. US is 125W, vs 250W for International. I am assuming this is where there might be a problem/issue.

I'm assuming your mean 120V, vs. 250V ... correct? Regardless, if you look closely at the fine print on the power adapter, you should see that it covers that range, albeit very hard to read. You should be able to swap out the proper wall outlet plug for your region.

Not so much charging time, it will be using the correct adapter for the model of your notebook.

For that, please take a look at the following support article: Identify your Mac power adapter - Apple Support

The computer is running the entire powering and charging process. it only draws as much power as it needs.

Using a power adapter that is larger than the spec has never been an issue, as long as everything fits together without being forced. The computer only draws what it needs.

Using a power adapter smaller than specified can cause some problems, but is usually not dangerous -- it may not perform adequately when trying to run AND charge.

Using a power adapter at least as large as specified is the 'Approved Method'.

You're very welcome!
