I have an older 13 inch laptop MacBook an I need a new power cord an do not know what kind to get.

iMacs don't run iOS.

tells you what power adapter to get.

Also all notebooks after 2006 were Intel, not PowerPC.

You can get a new third party 60W power adapter on eBay for under $20.

Or for $80 from Apple http://store.apple.com/us/product/MC461LL/A

I personally would not buy something that can be so badly abused on eBay. You have no idea the life history of the device. See what can happen*:

And you ask me, is there anything anywhere good as new as long as you give it a good lease on life? You have no control over the life of the device you buy on eBay, if you even get it.

Tjhe power adapters on eBay are mostly barnd new. Apple doesn’t make any power adapter. They buy them from the same manufacturers that the third party sellers are buying from. The only difference is that Apple has their logo imprinted on the power adapter.

Brand new? You call out of the box brand new? I looked at your pictures. The vast majority weren't even in their original box. Anything outside the box isn't brand new. Granted something sitting around in some warehouse for 3 years isn't exactly new either, but at least the cables have not been frayed. If they want to sell it brand new, they better be shrinkwrapped in a box made by Apple, undamaged, and refer to the Apple article that says this is for XYZ computer.
