Great for small audio projects.
Really simple. You can parallel the inputs to many of these IC with a pre-amp to drive lots of 3Watt 4ohm speakers and get decent sound volume. 1 x 18650 3500mAh lithium ion battery powers 2 units at the same time for 12watt pmpo for........drum rolll 3 days at mid volume.As these circuits run from 2.5-5.5 volts a li-po battery seemed perfect, if expenisve. They are REALLY efficient being a D type amplifier (85-90%) and draw 10's of milliamps @3.7v.

Tiny amplifiers great for all sorts of projects.
Extremely small, and work on as little as 2.6v, however just be aware they did get rather warm on 5v, I find they work very well with no heat on 3.7v range, no audio clipping, you can also run a pot in line with the signal input to get volume control, But these are tiny, decent audio quality, perfect for getting audio into your projects.

Was good , too good , wasn't expecting the sound to be so loud , jumped out of my skin
Wired up to an original xbox with internal speakers these small power amps definitely pack a punch! Recommended , just a quick note be sure you have the correct voltage maybe a potentiometer connected at lowest volume setting and go from there
