TC Electronic Tonefuel Power Supply Adapter

Eight-Output Pedalboard Power Supply with USB-C Input

The Tonefuel 8 is a dedicated multi-output power supply built for guitar and bass players running medium-to-large pedalboards. Eight barrel outputs on a single chassis replace the tangle of individual wall-warts and daisy chains that typically clutter a stage rig. The unit accepts incoming power through a USB-C socket, aligning the pedalboard with the same cable standard used by laptops, phones and modern chargers.

Center-minus polarity at 9V matches the wiring of virtually every mainstream guitar effects pedal, so most stompboxes plug straight in without polarity adapters. Six outputs deliver 100 mA and two deliver 300 mA, allowing analog drives, modulation pedals and digital units to share one power brick. The barrel plug format keeps cabling tidy under the board, and the included AC adapter plus power cable mean the rig is ready to play the moment the box is opened.

Output Architecture for Mixed Pedalboards

Distributing power across eight separate outputs lets a player keep digital and analog circuits on independent feeds rather than chaining them together. This matters whenever a noisy digital pedal shares a board with high-gain drives or vintage-style analog circuits that pick up interference from shared power rails.

• Number of Outputs: 8 — enough capacity for a full performance board without resorting to splitters or daisy chains
• Current Tiers: 6 × 100 mA, 2 × 300 mA — covers both low-draw analog pedals and mid-demand digital units from the same supply
• Voltage: 9V — the standard operating voltage for the majority of guitar and bass effects pedals

Connectivity and Cabling

USB-C as the power input is a practical choice for touring players who already carry USB-C chargers for laptops, tablets and phones. A USB-C charger or power bank rated 5 V / 3 A can power the Tonefuel 8 in place of the bundled adapter when space is tight.

• Power Socket: USB-C — modern, reversible connector shared with laptops and mobile devices
• Adapter Type: USB-C — input side matches the power socket for a clean single-cable feed
• Adapter Shape: Barrel — standard 9V pedal plug on every output
• Polarity: Center Minus — the convention used by virtually all mainstream guitar pedals

Package and Setup

Everything needed to bring the board to life ships in the box, removing the usual accessory shopping list that comes with most power supplies. Players can unbox, mount under the board, plug in the pedals and play.

• Package Content: AC Adapter, Power Cable — no extra parts required for first use
• Adapter Included: Yes — the wall-side power source is part of the bundle
