Review on WHDTS Stereo Bluetooth Power Amplifier Board with Infrared Remote Control – 5V/12V/24V, 20W/30W/40W – Complete with Case by Ivan Carson

Pro's - Very small and compact bluetooth repeater connects to my phone easily. (Motorola Z3) Includes acrylic case. Comes with a remote control and multiple power input options. Cons: I wasn't able to test much, but the acrylic case was already cracked on a thin edge near the speaker-out and power-in screw terminals. In general it's fine. In the limited testing I ran there was some noticeable distortion when the volume was turned up, but this could be due to running on the 9 volt battery or the fact that the speakers were outdoors. It's amazing that this thing works with a single 9V battery, but I'll happily test it with a higher voltage source later by getting a larger 12V battery and even a laptop adapter for voltages over 12V look at It can take up to 26V, so I'm looking forward to pushing this device with some decent speakers and a case. This would be great for a mobile speaker box project.
