Power Supplies

Where can I buy a tattoo power supply in Canada?

Maple Tattoo Supply stocks professional tattoo power supplies and wireless batteries from Critical, FK Irons, Cheyenne, Bishop, EZ, Darklab, and ALP — shipped fast from our Toronto warehouse across Canada, priced in CAD with no surprise fees at the border. Entry-level wired units like the ALP Digital start at CA$89.95; high-end options like the Critical XR and Cheyenne PU IV are also in stock.

What voltage should I set my tattoo power supply at?

There's no single voltage — it depends on your machine, the cartridge or needle grouping, and the work you're doing. As a rough guide: rotary pens often run between 7–9V, coil liners between 7.5–9V, and coil shaders 8–10V. Lining typically runs slightly hotter than shading. Most modern digital power supplies let you save presets per machine. Always start at the voltage recommended by your machine manufacturer and dial in by feel from there.

How do I connect my tattoo machine to a power supply?

For wired setups: connect the RCA or clip cord from your power supply to the matching port on your tattoo machine, then plug in the foot switch (if your unit uses one). For wireless setups: charge the battery pack, attach it directly to the machine's RCA port or grip, and follow the manufacturer's pairing/activation steps for that specific model. If your power supply isn't outputting voltage, check the cord, the foot switch connection, and the fuse before assuming the unit is faulty.

Wireless or wired tattoo power supply — which is better?

Both have their place. Wireless battery packs like the Critical Connect, Bishop B-Charged, FK Irons PowerBolt, and Cheyenne EnGen free you from clip cords — ideal for conventions, guest spots, and tight workspaces. Wired units like the Critical Atom X, MNML, and ALP Digital give you unlimited session time, no battery management, and a slightly more stable voltage curve over long sessions. Many working artists keep one of each on the bench.

How long do wireless tattoo batteries last on a charge?

Most modern wireless tattoo batteries deliver anywhere from a few hours to a full studio day on a single charge, depending on the unit, the voltage you're running, and the machine's draw. Higher-end models like the Critical Connect V3 and FK Irons PowerBolt are designed for full-day reliability. Keeping a spare battery on a charging dock is standard studio practice — it eliminates downtime if a session runs long.
