Cioks 4 Power Supply Expander
One case scenario might be, that instead of placing it under a big board to cope withe the power needs of extra pedals, you can neatly power a tiny fly board using (for example) an old laptop power pack, or even a travel mobile phone battery recharging pack. Very clever!
4 isolated outputs with selectable voltage 9-18v at up to 660mA each. Can deliver 24W as long as that's covered by the supply being used.
I have steadily been swapping everything over to CIOKS. The best in class in my opinion.
