Match every pedal before choosing a supply
Best Pedalboard Power Supplies for Voltage, Current, and Board Fit
Choose DC7 v2 for seven fully voltage-selectable feeds, Zuma for nine 500 mA feeds at 9 V, or SOL for five fully voltage-selectable feeds in a one-inch integrated-mains chassis.
Desk research updated : exact manuals, Sweetwater US, Thomann Europe, warranties, and separate attention sources were checked. We did not bench-measure electrical or audible performance.
Start with the board you actually have
- Avoid: any supply plan that guesses DC/AC type, voltage, polarity, current, or connector.
- Verify: the exact regional package, mains lead, cables, installed clearance, return window, shipping or return cost, and warranty territory.
- Jump to the exact outlet comparison or build the power passport.
Read a power label without guessing
Voltage
Electrical potential, stated in volts.
The pedal must explicitly accept the selected voltage.
Copy it from the exact pedal or its current manual.
More voltage is not free headroom unless the pedal maker allows it.
Current
The amount a pedal draws, stated in mA or A.
The outlet must provide at least that much at the selected voltage.
Use the pedal maker's requirement and keep some allocation margin.
A 500 mA outlet does not force 500 mA into a lower-draw pedal.
Polarity
Which connector contact is positive and which is negative.
Wrong polarity can stop or damage equipment.
Match the symbol and use only the correct approved cable.
The same barrel size does not prove the same polarity.
Isolated output
An output electrically separated from the supply's other pedal outputs.
Isolation can prevent one pedal's ground or switching behavior from sharing a direct path with another.
Confirm that each named pedal outlet is individually isolated.
Several sockets can still share one electrical output.
AC versus DC
Alternating current and direct current are different supply types.
Every recommendation here provides DC pedal outputs; some equipment requires AC or its own adapter.
Keep original adapters in the plan when the manual requires them.
A matching voltage number alone is not compatibility.
Connector
The physical plug and socket format at both ends of the cable.
CIOKS uses RCA-style supply-side sockets; the other picks use conventional 2.1 mm pedal-output sockets.
Map supply end, pedal end, size, and polarity together.
A cable that physically fits may still be electrically wrong.
Current doubler
A specified cable that combines current capacity from compatible outputs at the same voltage.
It consumes two outlets for one pedal.
Use only the supply maker's documented arrangement.
It is not a voltage doubler or an excuse to ignore total load.
Voltage doubler
A maker-approved cable arrangement that combines two compatible isolated outputs to provide a higher voltage.
It consumes two outlets and can damage equipment if the resulting voltage is not explicitly accepted.
Use it only when both the supply maker and exact pedal instructions permit the arrangement.
It does not add current capacity or turn an unsupported voltage into a safe choice.
Split or daisy-chain cable
A cable that connects several pedals to one supply outlet.
It does not create independent isolated feeds: the connected pedals share that outlet.
Use it only when every connected pedal accepts the same voltage and polarity, and keep their combined current draw within both the outlet and whole-system limits.
More plugs do not turn one isolated outlet into several isolated outputs.
Installed clearance
The space for chassis, plugs, cable bends, mounts, switches, and any external brick.
A bare supply can fit while the powered system does not.
Mock up the largest published envelope before ordering.
“Low profile” is not a fit certificate for your board.
Where specifications stop and listening starts
The recommendation lanes use exact outlet maps, current limits, dimensions, package contents, expansion paths, warranty terms, and current regional ordering. CIOKS DC7 v2 appeared first on Thomann's separate CIOKS Top Products list; Zuma had 103 reviews and SOL had 42 on separate Sweetwater reviews pages. Those are dated attention signals only.
No credible independent comparative electrical test with a published method covered all three recommended exact products. The guide therefore does not award “quietest,” “most reliable,” or “best regulated.”
Guitar World explicitly said it obtained two Canvas Power 5 units and used them in a linked setup with a Canvas Power HP through a series of rehearsals. Acquisition status was not published beyond “obtained,” and exact duration was not published. That two-unit source supports only its attributed enclosure and socket observations: it published no electrical measurement method, did not establish production variation, and cannot predict the delivered unit or your rig.
Compare the exact usable outlets
| Model | Isolated pedal outputs | Voltage/current map | Power package | Main catch |
|---|---|---|---|---|
| CIOKS DC7 v2 | 7 | Every outlet: 9 V/660 mA, 12 V/500 mA, 15 V/400 mA, or 18 V/330 mA | Integrated universal AC input; expands with CIOKS 4, CIOKS 8, or Crux | Maker page and manual feature list/itemization say 12 Flex cables, but the same manual's box summary says 9; verify the sealed box |
| Strymon Zuma | 9 | Seven 9 V/500 mA; two selectable 9 V/500 mA, 12 V/375 mA, or 18 V/250 mA | Integrated universal AC input; links Ojai or Ojai R30, up to six units | Only two voltage-selectable outlets; no 15 V setting |
| CIOKS SOL | 5 | Every outlet: 9 V/660 mA, 12 V/500 mA, 15 V/400 mA, or 18 V/330 mA | Integrated universal AC input; nine Flex cables | Only five isolated feeds; RCA supply-side sockets and an 88 mm chassis depth must suit the board and cable plan |
Choose by voltage range, outlet load, and installed fit
Every outlet may need a different voltage
CIOKS DC7 v2
Choose DC7 v2 when seven feeds are enough but voltage flexibility is not negotiable. Each isolated outlet has the same 9/12/15/18 V choices, and the 25.4 mm chassis is the lowest here. Individual outlet LEDs and the total-load meter give the buyer a documented way to spot overload conditions; they do not prove how the complete audio rig will sound.
- Complete current limits for every voltage; the 24 V output supports CIOKS 4, CIOKS 8, and Crux expansion
- Designed in Denmark, assembled in Poland, with a stated five-year worldwide warranty
Tradeoff: seven outlets may force an expander, while the RCA supply-side sockets make the Flex cable system part of the purchase decision. The maker page and manual feature list say 12 Flex cables and the manual itemizes 12, but that manual's box summary says 9; verify the sealed package.
Avoid if: you need more than seven independent feeds immediately or any pedal requires AC output.
Alternative: Zuma when nine mostly 9 V pedals matter more than per-outlet voltage choice.
Exact v2 manual, maker, Sweetwater, and Thomann evidence is current, with the cable-count conflict preserved. Thomann listed the v2 in stock and ready to ship when rechecked. The v2 is new, so older original-DC7 reviews are not treated as exact performance evidence.

Nine high-current 9 V feeds with integrated AC
Strymon Zuma
Zuma is the cleanest map for a board dominated by 9 V pedals drawing no more than 500 mA each. Two channels can instead provide 12 V/375 mA or 18 V/250 mA, and the 24 V output accepts Ojai or Ojai R30 expansion units; current Strymon support permits up to six. That topology is verifiable; Strymon's audible-noise superlatives are not used as ranking evidence.
- Nine isolated outputs and an integrated 100-240 V AC input
- Five-year warranty, USA build, and documented Ojai/Ojai R30 expansion up to six units
Tradeoff: there is no 15 V setting, only two channels change voltage, and current Strymon support versus Thomann pages differ on whether ten or nine pedal cables ship.
Avoid if: more than two pedals need a non-9 V output or a 46 mm chassis will not clear your board.
Alternative: DC7 v2 when voltage choice and a 25.4 mm chassis are the harder constraints.
Output limits, size, expansion, origin, and warranty are supported by current exact pages. The support page prints 1.25 lb and 680 g together, but those values do not convert to each other; keep both as a source conflict and verify the unit or packaged weight if it affects mounting. Also verify the sealed regional cable count.

Five voltage-flexible feeds in a one-inch integrated-mains chassis
CIOKS SOL
SOL is the strongest current fit when five isolated feeds are enough and the chassis must stay about one inch high. Every outlet offers 9 V/660 mA, 12 V/500 mA, 15 V/400 mA, or 18 V/330 mA, while the integrated 100-240 V AC input removes the separate brick that Canvas Power 5 needs. Sweetwater's exact black configuration and Thomann's exact SOL were in stock when checked.
- All five outlets have the same four voltage choices and a higher 9 V limit than Canvas Power 5
- Integrated universal mains, nine Flex cables, and included Pedaltrain/Templeaudio mounting hardware
Tradeoff: the 130 x 88 mm footprint is deeper than Canvas Power 5, and the RCA supply-side sockets make the correct Flex cables part of the fit and spare-cable plan.
Avoid if: you need more than five independent feeds, any pedal requires AC output, or the 88 mm depth plus mains-cable access will not clear the board.
Alternative: Canvas Power 5 only when its shallower 54 mm depth or conventional 2.1 mm sockets is the hard constraint and you can place and verify the external brick; DC7 v2 is the current step-up for seven feeds.
SOL beat six direct same-lane challenges. Fender LVL5 loses at 42 mm with fixed 9 V outputs. Truetone CS6 is 31 mm high, only two outlets provide 9 V/500 mA, and none offers 15 V. Exact maker evidence now confirms RockBoard V6 IEC at 35 mm with only two selectable outlets. R300 is 30 mm high with one selectable outlet and a higher checked US price. Canvas is cheaper and shallower but uses an external brick, changes voltage on only one outlet, and retains a brick-rating conflict. The older ISO-5 has far stronger retailer attention than several challengers, but it is 44 mm high, its 9/12 V sockets share one 400 mA section, three feeds stop at 100 mA, it lacks 15 V, and its 120 V and European mains versions are different regional units.

Build a power passport before shopping
Copy
For every exact pedal, record DC or AC, voltage, polarity, minimum current, connector, and whether the maker requires its original adapter.
Assign
Write one exact supply outlet beside each pedal. Mark every reversal, current-doubler, or voltage-doubler cable and the extra outlet it consumes.
Total
Check each outlet limit and the supply's total-power rule. A split or daisy-chain cable does not create independent isolated feeds: every connected pedal must share the permitted voltage and polarity, and their combined draw must remain within both the outlet and whole-system limits.
Reject
Reject the supply if any row needs guessed voltage, wrong polarity, insufficient current, an unavailable cable, or a connector forced to fit.
Mock the installed system, not the bare chassis
Cut cardboard to the published length and depth, then add the actual bracket position.
Add mains-cable access, plug bodies, bend radius, expansion cables, and any external brick used by an alternative.
Leave room to see fault LEDs, reach voltage switches, disconnect mains, and remove a failed cable.
Tape the mock-up beneath the board and press every corner on the floor. A supply that blocks a foot, pinches a cable against the stage, hides a voltage switch, or leaves an external brick loose is not an installed fit.
The central performance question needs your rig
Will the supply hold the required voltage and isolation under the board's real combined load without adding hum, high-frequency whine, dropouts, fault behavior, or problematic heat? Specifications can reject an impossible map, but they cannot answer that whole question for your pedals, patch cables, amplifier, wireless gear, venue power, and mounting.
Safe default before opening: identify the exact seller, country and item; confirm that this supply is eligible; ask what opening or electrical use is allowed; and record the required condition, packaging, refund form, return-shipping cost, and exceptions. Keep every accessory, document, UPC-bearing box and shipping carton. Complete the power passport and cardboard installed-fit rehearsal unpowered, without adhesive, mounting marks or discarded packaging.
Sweetwater US order
Sweetwater's current new-product policy says the usual clock is 30 days from shipping and the remedy may be a purchase-price refund, in-house credit or exchange. It requires a return authorization from a Sales Engineer and the received condition, accessories, documentation, original box/packaging and intact UPC; double-box again if it arrived that way and use trackable shipping. Free outbound shipping is deducted from the refund or credit. The page does not promise return-label cost or permission to open and energize a supply. It lists special orders, customer modifications, software, oversize/overweight goods, discontinued/closeout/used goods and other categories as non-returnable; no membership rule is stated. Unless the Sales Engineer confirms this exact item's eligibility and the planned electrical check in writing, stop at the unpowered fit rehearsal.
Thomann Ireland order
For an Irish consumer, Thomann's first 14 days run from possession: send a clear withdrawal declaration (its template is optional), and the stated refund uses the original payment method and includes the cheapest standard delivery; Thomann says it bears return cost. Handling beyond what is necessary to check condition, features and functioning can reduce the refund. Days 15-30 are a separate extension: return the goods in proper condition, avoid ownership-like use or value loss, expect possible possession/use compensation, and note that Thomann says it cannot cover return shipping from foreign countries in that period. Custom goods, opened sealed hygiene/media/software, wear items including cables and plectrums, and used safety-property items are among the exceptions; no membership rule is stated. The extended-period refund method and an original-packaging requirement are not explicit. Confirm the exact supply's eligibility, allowed opening/use, packaging expectation, refund form and Irish return cost before energizing it or discarding anything.
Only after the fulfilling seller confirms the planned use preserves your intended remedy: leave the supply loose on a dry, ventilated surface, record a guitar-to-amp baseline at an ordinary listening level, connect one correctly mapped pedal, then add the rest one at a time for a brief function check. Stop and unplug for new hum, high-frequency whine, dropout, fault LED, loss of power or unusual heat. Do not rehearse, gig, attach hook-and-loop, open the chassis or probe mains circuitry.

Close alternatives, conflicts, and the modeller boundary
- Walrus Audio Canvas Power 5: cheaper, shallower, and conventionally socketed, but displaced by SOL because it needs an external brick and only one outlet changes voltage. Preserve the conflict: Walrus and Sweetwater's compatible-brick page support 24 V/2 A and 48 W, while Thomann lists 24 V/4 A and 96 W. Walrus does not publish exact origin; Thomann says Made in USA.
- Fender Engine Room LVL5: five fixed 9 V/500 mA outlets and 42 mm high. Fender direct gray was sold out, but exact Sweetwater US and Music Store Spain EU listings were orderable. It loses on fit and voltage flexibility, not general availability.
- Truetone 1 SPOT Pro CS6: the strongest cheaper compact integrated-mains challenge, current in both checked regions with a five-year original-purchaser warranty. It is 31 mm high, only two outputs provide 9 V/500 mA, the remaining four are lower-current switchable pairs, and none offers 15 V. Thomann reverses the official numbering of those pairs, so follow the current official diagram and delivered label.
- RockBoard ISO Power Block V6 IEC: exact maker page/manual confirm article RBO POW ISO 6 IEC, six isolated outputs, 100-240 V input, six pedal cables, 130 x 88 x 35 mm and 386 g. It remains a credible cheaper integrated-mains option, but it is 35 mm high and only two outlets are selectable. The maker publishes support contacts but no written warranty duration or remedy.
- Strymon Zuma R300: current five-output integrated-mains alternative, but 30 mm high, one variable-voltage outlet, no 15 V option, and a higher checked US price than SOL.
- Voodoo Lab Pedal Power ISO-5: the serious older popularity challenge: Sweetwater's separate page showed 54 reviews and Thomann Germany showed 214 ratings. It is 44 mm high; three isolated sections provide only 9 V/100 mA, the 9 V and 12 V high-current sockets share one isolated 400 mA section, the remaining section is 18 V/100 mA, and there is no 15 V. Buy the exact regional mains model—the US unit is 120 V, while the maker's Europe/Australia page/manual disagree between 230 V and 240 V, so the bottom label governs. Its five-year written warranty is North America-only, original-purchaser and non-assignable; other regions must obtain terms from the country distributor. SOL still wins the stated low-profile, five-flexible-feed lane.
- Walrus Canvas Power HP: availability-watch for the separate modeller lane. Its exact page provides one 3 A output selectable to 9 or 12 V plus three 9 V/500 mA outlets, but says new orders ship late July. If your modeller needs 1-3 A, start with its maker-supplied adapter specification. Do not combine normal pedal outlets or substitute another supply until the exact voltage, current, polarity, connector, and ordinary orderability are confirmed.
- Truetone 1 SPOT Pro CS7: the current product page says output 1 is 9 V/100 mA, while its linked manual and current retailer pages identify a dedicated 18 V/100 mA output.
- Voodoo Lab Pedal Power 3 Plus: its current page and June 2026 manual disagree on one switchable outlet's current, and the page also contains conflicting dimensions.
- Fender Engine Room LVL12: the exact product page retains conflicting physical dimensions, which defeats a confident installed-fit recommendation.
Ask the seller before connecting
- Is this the exact model and standalone package shown here, with the correct regional mains lead?
- How many pedal cables are in this sealed regional box, and which nonstandard connectors are included?
- Does the warranty stay in the purchase region, and who handles service locally?
- For this seller, country and exact item, what opening/use is allowed, what condition and packaging must return, which refund/credit/exchange applies, who pays each shipping cost, and which material exceptions could remove eligibility?
- Which approved cable powers each nonstandard pedal without changing its required voltage or polarity?
