In this video, I'll show you how to change the USB power supply of some speakers so they get their power directly from the mains using a wall adapter. And you know what to do: subscribe, it's free!!! Thanks a lot, guys!!!!
I wanted to show you this modification so you wouldn't be afraid to upgrade or adapt electronic components. The speakers were powered by USB, but they introduced noise, so the sound was terrible.
I cut the USB and used an old phone charger with a mini USB connector, at 5V. Keep in mind the voltage, which is 5V DC, and the current, which shouldn't be too low, so it has enough power.
In the end, I added a single-phase switch so it's not always powered. I hope this is helpful, and you know what to do: subscribe, it's free!!! Thanks a lot, guys!!!!
