It's not a bad package for $27, but keep in mind that, especially with the included 12V PSU (rated up to 14.4V), it's only good for about 10W/channel before THD get excessive, same as you'd find with any class D amp running off such a low voltage except in car audio where there's an internal boost circuit to increase operating voltage headroom.

That's enough for a small room, wouldn't be too bad as a bookshelf speaker amp for a computer/etc if you don't expect high volume.

Or they need to increase the amperage of the PS it’s rated at 2AMP but then more expensive to build/sell

watts = amps × volts
watts = 2A × 12V = 24W

^ 2A is enough current for 12V, it's a design with a ceiling based on the max input voltage the IC can tolerate. At the same time, with its 14.4V max, there are some laptop chargers that offer 14.4V and higher current so that would be ideal to make the most of this, but if you're buying a PSU too because you need that little bit more, would be easier to just step up to an amp with higher ceiling output to begin with.

Depends on the purpose. I have an amp with a sonic impact TDA2024 board in it, self-built into a router case with a built in 1.5A transformer and it does fine, but it has oodles of extra capacitance on the output to ride through the heavy bass notes.
