The Godlyke Cable-M/M adapter cable features two standard-sized male barrel plugs, both with tip-negative polarity. The C-M/M allows users to connect any of the Power-All Extension Jumpers or Daisy Chain cables to power supplies with female barrel jacks, such as the Voodoo Labs Pedal Power, T-Rex Fuel Tank, BBE Supa-Charger, Mod-Tone Power Plant, etc. The C-M/M can also be used to connect pedals directly to these devices in order to be powered.
