I love it, the power is limited obviously but enough for my purposes.

great little amp, powered two 4 inch car speaker with 12v at ~1.2A

Better than computer speakers for volume and audio quality, but not enough power to adequately drive most bookshelf speakers.

Using it to power two decently large Polk speakers and it has enough power to get loud, clear sound out of them.

Both the power supply and amp heat sink run cool at 5V.

Good, clean power, but not all that loud at max volume.

Actually fairly impressed with this, sounds good, has decent power, wish it came with paper work.

wiggle it and it will lose power

I love it, the power is limited obviously but enough for my purposes.

is great once you have the right power supply it works perfectly 12 volts (5 amps or more) buy it you will not regret it

This amplifier has great power for its price

This puts out very little power, maybe enough to power a pair of headphones.
