Independent shopping perspective
The Korena take
Canvas Power USB connects a USB-C Power Delivery source to a pedalboard power unit with a 24V EIAJ input, while also providing one isolated selectable 9V, 12V or 18V pedal output. If a 24V DC supply is connected, the unit gives that source priority; otherwise it runs from USB PD. The compact metal enclosure measures 3.7 by 2 by 1 inches and includes mounting hardware, an EIAJ link cable, USB-C cable and a straight-to-right-angle DC cable for a tidy board installation.
Strong match
Who this is for
- Pedalboards using a Canvas Power unit or another supply with a 24V EIAJ input.
- Adding one isolated 9V, 12V or 18V pedal output to a board or desk setup.
- Using a qualifying USB-C PD source when a 24V DC supply is not connected.
Consider the trade-offs
When to look elsewhere
- USB Power Delivery sources rated below the required 30W.
- Setups needing more than one selectable 9V, 12V or 18V pedal output.
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Selectable isolated pedal output
Choose 9V at 500mA, 12V at 375mA, or 18V at 250mA for the single DC output.
Detail 03
24V EIAJ pass-through
The 24V output can feed a pedal power brick through its EIAJ connection.
Detail 04
LED power meter and output-status LED
The indicators show power status and whether voltage is present at the output jack.
