I’m selling a new Neeware 48volt phantom power supply. It is used to power condenser microphones. The power supply can be powered from any USB port or a standard 5volt USB power brick. It is high quality, low noise supply that designed to be portable. I have two but only need one. Only the new Neewer 48volt phantom power supply, USB power cable and manual are for sale (the ad picture is stock from Neewar)
