Question about power adapters
Cross post from another forum, but would also like your opinion...
I have way to many wall warts and power adapters. Is it possible to combine them with daisy chain adapters?
For example, here is what I have...
Positive Center
0-Coast
adapter: 15v .4A (+)
OTII
Adapter: 12V 2A (+)
Push 2
Adapter: 12v 1250mA (+)
monostation
adapter: 12V 1200mA (+)
minilogue xd 9V
Adapter: 9v 1.7A (+)
Bastl Softpop
7-9VDC (+)
Negative Center
sp404
adapter: 9v 2A (-)
Zoia
9V DC 300mA (-)
In this case, could I use a daisy chain and split the Octatrack MKII power supply to the push 2 and monostation?
Could I also use the Octatrack Power adapter with the 9V items as well?
Have always just used the included adapters, but with more and more gear, it is becoming hard to find enough outlets.
Thanks for your help.

It would not have enough power to supply all three machines. It would need to be a 4,5 A adapter. Also daisy chaining will cause a ground loop hum. Another power strip is what is needed.
You could also look into splitter power cords:

But as @Alfred said, I’d rather have a rat’s nest of power strips and adaptors than an elusive ground loop.
It's been ages since I built a power supply....
A lot of what I'm about to say may be dated information....
In my opinion....
Not all external power supplies work the same way.
Some external power supplies are simply transformers having a secondary winding that provides a "raw" "AC" output voltage to a device that has rectifier circuit located within the device itself. This is where the conversion to DC voltage takes place, and there are many different way of constructing a rectifier circuit. Some output voltage is "cleaner" than others.
Some external power supplies will have a rectifier circuit built-in. This can be advantageous in hardware design, as the hardware device won't require the extra space for internal rectifier circuitry, nor will the design have to compensate for the heat that certain types of rectifier circuits are prone to producing.
Those ratings printed on the exterior of an external power supply don't always represent an absolute voltage output.
A cheepo AC supply that says 12V 500mA, may literally mean that it will output 12V only while the device it is powering is drawing 500mA. If you experiment with the output on these AC supplies, and measure the output voltage while drawing 50mA, 100mA, and then 250mA, you may find the supply putting out 25V @ 50mA.
In other words, the supplies are very often matched to the devices they are powering, and you may often find a warning either printed on the device, or in the device literature, that specifies that only "approved power supplies" be used with the equipment.
External DC power supplies can also vary in the quality of their output voltage. An experiment is to take various DC supplies and monitor their respective outputs using an oscilloscope. Some DC power supplies will show much more "noise" (or ripple) than others. This has to do with the design of the internal rectifier circuitry, and the type of filter used within that rectifier circuitry.
External DC power supplies may have a relatively clean output when pulling only half their rated output, but as you pull an increasingly higher amount of amperage, and approach the Amp rating of the supply. The oscilloscope may show a correlation of increasing noise in the DC current, as higher levels of current are drawn from the power supply.
This is because the filter circuits in rectifiers tend to operate most effectively in the low to mid limits of their operating outputs.
External power supplies can also be designed as "high frequency digital switching power supplies" that provide a very clean DC output over a range of amperage draw. You'll find switching supplies in computers and other types of sensitive electronics that require a very clean DC voltage to assure proper operation of sensitive components.
Unless one has the knowledge and to tools to measure the actual values and quality of the output of a factory supply while the device is in operation, one would just be guessing at the voltage spec that the particular device was designed to operate with..... Unless there is something provided in the device instructions that specifies power supply requirements.
If I recall correctly... Boss allows daisy-chaining power to their Guitar Effect Pedals using the correct AC adapter. But I'm fairly certain that the Boss AC adapters that are intended for this purpose, are of the high frequency digital switching type.
In summary, playing with daisy chaining power supplies in any haphazard experimental fashion, may possibly result in unsatisfactory results, or in the worse case, damaged equipment, or even overheating supplies with a potential of causing a fire.
You could probably get ripchords for most of those.
