2x6W DC 5V 3.7V speaker modified Stereo Bluetooth amplifier board can connected lithium battery with charge management A8-020

Good price, everything is working properly. Column came to life.

The sound quality is normal. Module was cut down the high volume even with 8 ohm speakers, with speakers 16 ohm worked fine, the food was 2A. Problem was solved by replacing capacitors 1500 microfarads 6.3в, (vypayal motherboard from coma), now on even at maximum volume

As see in the photo, amplifier board in their original packaging, all items are carefully.Appearance-All good.Connect for sample 2 speaker, powered by the USB charging 1A (the description given two modes-powered by USB and external battery).Via bluetooth with phone connected, checked the sound is loud enough.For my money is OK, there is slight hiss, a bit like a vinyl :)

Perfect, pending check, greetings

Works as expected, for a great price. Delivery in around 10 days
