TC Electronic Tonefuel Power Supply Adapter

USB-C Powered Multi-Pedal Power Supply

The Tonefuel 4 is a compact pedalboard power supply delivering stable 9V DC to up to four guitar effects pedals from one unit. Powered via USB-C, it removes the need for multiple wall-wart adapters and brings modern connectivity to any rig. Each output runs at 9V with center-minus polarity through a standard barrel connector — the configuration expected by most stompboxes. Ships with an AC adapter and power cable, ready to plug in straight from the box.

Isolated Outputs for Mixed Pedal Draw

Every output is independently isolated to minimize hum, buzz and ground-loop noise between pedals. Two outputs deliver 100 mA for standard analog pedals, one delivers 400 mA and one 600 mA for higher-current digital or multi-effect units, so a small board or a satellite supply for a couple of demanding pedals runs from a single unit.

Output Configuration — Standard Pedal Compatibility

Every output delivers 9V DC at center-minus polarity through a standard barrel connector — the configuration used by virtually all mainstream guitar pedals.

• Voltage: 9V DC — universal compatibility with standard stompboxes
• Polarity: Center Minus — matches the convention used by most pedal manufacturers
• Connector: Barrel — fits standard pedal power inputs without adapters
• Number of Outputs: 4 — powers a small-to-medium pedalboard from one unit

Output Current

• Outputs 1–2: 100 mA — for standard analog and low-draw pedals
• Output 3: 400 mA — for digital and modulation pedals
• Output 4: 600 mA — for current-hungry digital or multi-effect units

USB-C Input and Included Accessories

The USB-C power socket (5 V / 3 A) accepts the included AC adapter, a power bank or any USB-C source rated 5 V / 3 A — useful for travel rigs and compact setups.

• Power Socket: USB-C — modern, universal input standard
• Adapter Included: Yes — AC adapter and power cable in the box
