I have about 20 to 30 peripherals on my computers. Each one with its own &%$/&#$% AC power adapter. I really hate these power adapters.
I am thinking of there's some kind of power supply I can buy (similar to those used in electronics) that comes with different voltages (typically +5 -5 +12 -12 +9 -9 and can even supply HP printers +36V if I am not wrong) and I can use to power all peripherals at once. One power supply with wires and plugs to all devices would be a wonderful solution.
Is there something I can buy or adapt to do this?
