Pedalboard Power Supply Pedal-board Power Supply Question?

Pedal-board power supply question? - pedalboard power supply

I received my first DIY pedal, and found that the use of power extended beyond socket is large, with all the 9V adapter, so I was looking for a way to save space and discovered the 1 SPOT 9V food, and wonder about the voltage, amps and everything. I think the use of these pedals:

Digitech Whammy IV
Digitech, "" Arms Dan Donegan Signature
Vox V847A Wah
BOSS DD-7 Digital Delay
MXR Phase 90

I wonder, can a power supply that all these pedals without them, or just something that all levels of output (voltage, amps, etc.) and can also use?
