NEOHIPO ZK-1002M 100Wx2 Bluetooth 5.0 Amplifier Board 2 Channel Mini Wireless High Power Digital Amp Module AUX USB Inputs for Home Passive Speakers

Did exactly what I needed it to do.

This is a very good little amp, supllies great sound and is capable of a decent output level. For the money it is absolutely a bargain. BUT one thing to note, do not connect the full 24volts to it that is is supposedly capable of taking. I have this connected to my USB port on my PC. When I power it from a 24volt supply Iou hear very little increase in output power, barely noticeable from the 12 volt supply, and more crucially, you will experience dropouts in the sound and the device will switch momentarilly to bluetooth mode, then switch back to PC mode. It runs perfectly on the 12 volt supply, i suspect that it overheatds a bit on 24 volts and is ok with 12 volts. I have not tried it on anything other than 12 and 24, so i am curious to try a 19v supply that I have, but since the 24 volt gave little benefit, i will stick with the 12 volt suppl. other than, it's excellent and 100% worth buying if you need a physically small amp like i did.
