MXR MINI ISO-BRICK POWER SUPPLY M239:
If you need a smaller solution for your travel pedal board or to power your go-to pedals for everyday jamming, this mini power supply is just what you need and fits in the palm of your hand.
With five outputs the Mini ISO Brick power supply will help get rid of that horrible loop noise. It runs 9 Volts of power at 300mA on 4 of the ports, and depending on what you need the 5th can either be set at 9 volts or 18 volts at 800mA. With this tremendous amount of available current this pedal can handle positive and negative grounds and will work with most pedals be it digital and analog.
This pedal comes with a splitter that allows you to add an extra pedal. You will be able to connect two pedals to a single output. They must be the same voltage and can not be more than the output's current rating. You just need to purchase the extra cables and you will be set.
On dark stages, troubleshooting can always be a problem. This Mini ISO brick power supply pedal comes with LEDs that way you know all connections are tight. It's very well built and lightweight. So from gig to gig your pedal board will stay powered for you with no problem.
