How do you pack your power supply to throw it in the bag?
I do it like this, but dont think it’s the best way:
I roll the cable making circles around the power supply.
I unplug the mini Euro connector from PSU, lay it along side the fixed cable then coil the pair with a slight twist of the thumb & 1st finger. This simulates the way the cable will have been rolled on to a drum after manufacture. End up with a coil the size of a plate. Small wrap of electrical tape keeps it in place.
If you continue to do it the way shown in the pic, the inner cores will break!
I’m talking about doing this on a daily basis not once in a blue moon by the way, lol
Look a the left side of the pic, you can see where the cables structure is already misaligned.
Hope that helps 
Thanks for the answer!!
Can you please post a photo?
I am not native english, so I dont really understand you well.
Here’s how I do it, this way it lays flatter in the front pouch of the ECC-2 Bag:
I would unplug the one cable from the power supply in the above pic.
I normally put plug to plug then loop the cable in half for all cables, midi, audio, power. Then just make one loop into itself.
Not very tight but will stay and will be real easy to loop and unloop.
OK. Thanks.
I need to do it this way or my power supply will not last long!
