@drewboy The QC will only draw a max of about 1.8A, and that’s during bootup. I got involved in determining the max draw because I have a Voodoo Lab Pedal Power 3+ that is advertised as being able to run the QC via the X-link port on the unit (1 of 2 ports that share 2A). I ran my own amperage draw testing and the max draw I found was 1.74A during QC bootup, 1.4A during actual usage (full screen brightness & CPU-heavy preset). So, the PP3+ lets you connect the QC to the PP3+ power supply via one simple 2.1mm pedal cable. SO much simpler than all the various CIOKS configurations that require either a CRUX unit, or parallel cables, or voltage doublers. AND, for the price of the PP3+, your get TWELVE more isolated power ports besides the X-link used to power the QC. (9) 500mA ports and 2 others that are switchable between 9V 500mA or 12V 200mA. I honestly don’t understand why the PP3+ is not the power supply of choice to power a QC on a pedalboard. Here is the link to the thread where I do all my testing and explaining":
