CIOKS DC7 Power Supply Review
Verdict and Review Summary
Without question, the two most attractive features of the CIOKS DC7 are the switchable power options for each port and the low-profile size of the unit. I also really like the flex 5.5mm/2.1mm power cables. An all-around win for CIOKS with no complaints from me.

The CIOKS DC7 is one of the most unique power supplies I've tested because of it's flex cables, switchable voltage on every single power connection, and the 5.5mm/2.1mm flex cables. It also comes with a daisy chain power cord that lets you string up to three pedals together. In the same vein, a split flex cable that lets you power two pedals off a single output is also included.

The DC7 has switchable voltage options for all power connections.
Cabling Breakdown
Here's how all the cabling breaks down:
- 7 x Standard Flex type 1 — black with 5.5mm/2.1mm center-negative DC plug
- 1 x Standard Flex type 2 — red with 5.5mm/2.1mm center-positive DC plug
- 1 x Standard Flex type 4 — green with 5.5mm/2.5mm center-positive DC plug
- 1 x Standard Flex type 5 — black with tip positive 3.5mm Jack plug
- 1 x Split Flex type 1 — powers 2 pedals off a single outlet
- 1 x 3-way daisy-chain Flex type 1 — powers 3 pedals off a single outlet
This makes the DC7 perhaps the most flexible power supply I've ever tested, given the following features:
- Ability to switch voltage
- Daisy chain-style cabling
- USB connection
- Extremely low/small profile
- Ability to expand to other CIOKS power supplies

Easily one of the most flexible and accommodating power supplies in the market.
Casing Profile
And as I mentioned earlier, the profile of the casing is pretty low and easily the slimmest that I've ever seen.
It's just 1" high.
To be honest, this is a brand I've overlooked for a long time, but shouldn't have. For a brick of this size, it can handle a ton of pedals, easily 10 or more given the switchable voltage on each outlet. All the while, it's very easy to hide and doesn't take up much surface area if you want to just leave it on your board.
Moreover, you won't be limited to using fewer outputs if you have, say, three 12V pedals. Just switch the voltage and you're good to go.

A few pedals I connected to the DC7 for testing.
Price and Volume
While you'd think it would be more expensive, it's right around the going rate for isolated power supplies at roughly $250. Keep in mind, that could change by the time you read this review, but I have absolutely no issues with the current price tag, and I'm honestly surprised it's not priced a bit higher.
There has to be some added cost associated with getting the interior of the pedal to fit in such a small casing, as well as the switchable power on each outlet.
At any rate, the value here is excellent.
Ideal Situation for the CIOKS DC7
The most obvious landing spot for the DC7 is a pedalboard with a lot of variance in voltage requirements. I'd also recommend it for a higher number of pedals, perhaps in the 8-12 range.
But even if you don't have a complex array of voltage requirements, this is a great power supply to have on hand in case your pedal roster changes, or if you want to expand with additional power supplies.
It's perhaps the most flexible power supply I've ever tested.
No complaints. Buy confidently.
