So, I got tired of waiting for the batteries for the nicostick I made and decided to make it a usb passthrough. It works good except it takes away the flavor of my juice. Its running at just above 5v. I'm thinking that's a bit much, is there something I can do to drop the volts down to just over 4v? Also when i use it, my laptop tells me that I'm exceeding the power limits of the port? Could my multimeter be off? All the help is appreciated.
