More power. Smarter tech. Same legendary performance.
Charge less, create more. The Power Wand you already know and love just got upgraded. Now outfitted with Bishop’s Advanced Battery system and sold with a complete set of game-changing accessories (listed below), this machine gives you longer sessions, smarter functionality, and a rock-solid snap connection. The new Advanced Standard Battery runs up to 15 hours, and the Advanced Shorty now pushes up to 6 hours — that’s hours longer than the OG setup, so you can power through full-day sessions without constantly swapping packs.
Choose your stroke. Pick your perfect fit: the 3.5mm Shader for buttery smooth black and grey, the 4.2mm Packer for rich saturation and color packing, or the 5.0mm Liner for bold lines, dotwork, and blackwork. (ProTip: The Shader operates best between 8.5v and 10v, while the Liner and Packer operate best between 6v–8v).
Snap in and stay locked. The new Snap Connection ensures a tight, stable battery fit — no wobbling, no disconnects. Plus, the sleek new magnetic battery backplate still rotates 360° for total visibility and comfort.
See more, control more. The upgraded TFT display is bigger, brighter, and now includes Hertz readouts, session time, runtime, and battery percentage. Total awareness at a glance.
Dial it in faster. With 5 onboard buttons, you can easily switch voltage presets, toggle a jumpstart feature, and swap left/right-handed mode — all without missing a beat. Hold the power button to start up or shut down, and tap it to pause mid-session.
Dock and roll. Every Advanced Set includes a Critical Universal Battery Dock to keep both batteries charged and ready to go. Whether you’re working long sessions or bouncing between pieces, you’re always powered up.
Please Note: Hertz offer a more accurate measurement of your machine’s performance, showing the exact frequency of needle movements per second. Voltage can vary depending on factors like the motor and friction, meaning that 8.0v on one machine could be 150Hz, while another might only reach 120Hz. By focusing on Hertz, you get a clearer, more consistent picture of your machine's output.
