In 2017 One Control released the DC Porter, which brought innovation to the power supply of the pedalboard power supply. In 2023, One Control has transformed the DC Porter into the next generation with the Minimal Series DC Porter MKII. DC PORTER MKII IS A POWER SUPPLY DESIGNED EXCLUSIVELY FOR MOBILE BATTERIES. Robust housing. The entire unit is sealed for stability. Powering your pedalboard from any standard 5V USB-C mobile power bank prevents the addition of noise generated by “wall wart” style adapters. At the same time, there is no need to open the back cover of each effector and replace the battery. Also, there are many effects that can't be battery-powered now. DC PORTER MKII CONNECTS POWER FROM ANY STANDARD POWERBANK STYLE BATTERY TO THE USB-C PORT. All DC outs are center minus DC 9V, and there are 10 outlets. It can power large pedal boards with ease. The current capacity that can be output depends on the connected mobile battery, but the maximum total is 1000 mA. There is no current limit for each DC 9V out. The DC Porter MKII also has an indicator that shows current useage. 300 mA, 600 mA, 900 mA, 1000 mA (overload) indicators light up. At 300 mA or less, only the blue LED of each DC 9V out lights up, and one when it exceeds 300 mA, two when it exceeds 600 mA, and three indicators when it exceeds 900 mA. Normally, if an indicator over 900 mA lights up, refrain from supplying more power. If the red LED overload indicator lights up, remove the mobile battery and remove all connections.
