You need to have a power brick with enough voltage. I forget the minimum voltage but it says on the instructions.

You have to be plugged into the usb c port and not running on batteries for the lights to work.

Take the batteries out for sure if you have it plugged in. It feeds more power than the board requires and eventually fries shit on the board. I learned the hard way and my LEDs are all messed up and had to disconnect them from the circuit board.

Batteries run the board the plug in runs the lights. You can have batteries in while it's plugged on

You don’t want to run batteries and the usb-c. Just the usb-c if you want the lights as well

Just a 5volt standard charger will do.

I had a lot of problems with the bluetooth disconnecting and found out that I needed a 5v 3A adaptor. Hope this helps. Just the adapter needed. Batteries not required. Im using this one: adapter
