The Canvas Power USB allows your rig to be powered by most USB Power Delivery (PD) supplies like laptop chargers, high power phone chargers, and even USB PD battery packs!
With the Power USB, you can now take your rig to even more places. Got an outdoor festival this weekend and the dive bar with only one outlet for the whole band the next? Grab a USB PD battery pack and you’ve got a wireless rig!
Here’s how it works:
- Power USB works as a bridge that goes between your Canvas Power unit (or other power supplies with a 24V EIAJ input) and its power brick or USB battery pack.
- Place the Power USB before your current power supply and connect them from the Power USB’s 24V Thru to your main supply’s 24V In with the included EIAJ cable.
- Your pedals can now be powered by a USB PD supply such as an adapter (like the one connected to your MacBook), battery pack, OR your canvas power brick!
- Power USB will prioritize the normal DC brick supply if present or use the USB PD input if no power brick input is detected.
Need to know for retailers:
- Versatile Power Solution: Canvas Power USB is a compact converter that enables standard power supplies to run off USB Power Delivery (PD) sources (minimum 30W) like laptop chargers, high-powered phone chargers, or USB PD battery packs, making it ideal for portable pedalboard setups.
- Easy Integration: Acts as a bridge between 24V EIAJ-compatible power-supplies (Strymon Zuma, Cioks DC7) or Walrus Audio Canvas Power units (e.g. Canvas Power 8) and USB Power Delivery sources using the included EIAJ cable for simple setup.
- Smart Power Switching: Automatically prioritizes DC brick power when available, seamlessly switching to USB PD input when no brick is detected.
- Clean, Flexible Output: Delivers isolated, low-noise power with a variable 9/12/18V output (up to 500mA), ensuring reliable performance for pedals in any gig setting, from outdoor festivals to small venues.
- Retail Appeal: Its slim design (fits under flat Pedaltrain boards), universal mounting brackets, custom low-profile cables, and LED power indicators enhance modularity and ease of use, meeting the growing demand for USB-friendly, portable gear that fits any pedalboard.
