Review on Nobsound Mini Bluetooth 5.0 Power Amplifier - Stereo Hi-Fi Digital Amp 2.0 Channel 50W×2 with AUX/USB/Bluetooth Input - Wireless Audio Receiver - PC Sound Card incl. Power Supply (Silver) by Christopher Shah

Out of the box this only plays music at an *extremely* low volume before shutting down, doesn't register with my computer's bluetooth (my phone only), and the power adapter caught fire when connected. When testing the bunk, the adapter only drew 2 amps. I replaced the included power supply with another one and it works great - all issues have been resolved. I'm still debating whether it's worth returning and getting a better one with parts that actually work. Sound quality isn't fantastic, but that's to be expected for a cheap little car. Good for casual listening. I hooked it up to vintage Wharfedale bookshelf speakers and it plays great from around the room. Doesn't spread across multiple rooms.
