I suppose you'll redefine powerful now, just as you did with portable, but
for the standard definition of powerful your statement above is rubbish.
Some desktops are more powerful than some laptops. The reverse is also true.
I'm betting you knew that.

And another
no-brainer is that laptops and smaller computers are meant to run
off of batteries.

By "meant to", I assume you meant "capable of", not that I expect you to
know the difference.

You're really not very good with words.
