Very powerful, it's a 3Wx2 amplifier, but i connect it on my computer and the sound that i almost couldn't hear beafore, now I can hear it without problem with the volume level in 10%
It also works with my cellphone battery(SKU.23723), but I use an USB port(~5v) as power supply, just get an USB cable from my old printer that don't work, cut it and plug on the device and works perfectly(red=+,black/white=-).
I don't know much about eletricity, so I've bought this one just to see if i could make it work and bought the SKU.44125 that is more powerful and it works.
