FK Irons Darklab: PowerBolt Plus II & Refuel Charging Dock Bundle (Two bolts + Dock)

This FK Irons Darklab bundle includes two PowerBolt II+ battery packs alongside the Refuel Charging Dock, engineered for rapid, simultaneous charging within 2-3 hours. Compatible across all PowerBolt iterations—including II, +, and II+ models—this dock features a magnetic anti-skid base and LED indicators that shift from red (charging) to green (fully charged), automatically ceasing power to preserve battery longevity. The PowerBolt II+ integrates a state-of-the-art motherboard offering real-time give adaptation, voltage adjustment (4-12 V in 0.1 or 0.5 V increments), and an OLED display presenting power output, battery life, give level, and session timer. Bluetooth 5.0 connectivity enables pairing with the Darklab app for voice control, firmware updates, and eGive settings, as well as compatibility with the Darklab Killswitch for wireless footswitch control. Backwards-compatible with FK Irons Flux, Flux Max, and EXO rotary machines, it supports up to 8 hours of continuous use on a full charge via USB-C. Designed and manufactured in the USA, this professional-grade kit optimizes workflow efficiency and machine responsiveness for precise tattooing performance.
