    Very nice amplifier that gives a very clean sound when driving good quality 8 ohm loudspeakers. Power is from an AC 100V-240V DC 24V 4A Banggood power supply and the amplifier mounts very neatly on two pieces of transparent 78×78mm×3mm Acrylic Sheet also from Banggood, please see the photos. I ran the amplifier at high power on the 8 ohm speakers in an ambient temperature of 20 deg C for 30 minutes and all parts of the amplifier and power supply stayed cool. I would expect the system to have a good service life. an excellent system for $20.

    A qualidade impressiona. Não da para escutar nem um 'chiado', ou falha. Eu o testei com apenas 9v e se saiu muito bem, mas a tensão ideal é de 12v a 24v, a temperatura certamente não passou dos 35C°. A qualidade de fabricação é ótima, com soldas muito bem feitas. Iriei fazer uma caixa de som portátil, vou alimentá-lo com 6 baterias de lítio 18650. Assim que eu terminar irei postar o vídeo aqui no campo de videos...

    The amplifier board is well designed and works fine. It took about 2 weeks to be delivered to Germany wiche is completely fine. What's nice about this Board is that the startup sound is placed back at a decent volume level (not like other cheap ones) the music quality is great. In combination with a 3s lipo and some car stereo speakers the volume is great for a mobile boombox. The only downside is the Bluetooth name that can't be changed.. but all in all its great product.

    Perfect if you want to make a portable speaker that is head and shoulders above the kind u can buy pre made with inbuilt speakers. Make a custom speaker enclosure and it will be louder and sound better. Good price. Very much, just plug and play.

    Ca c'est très bien, fonctionnement parfait, seul la disposition des boutons pose problème pour l'intégration dans un boitier. Mais rien de bien grave.
