Supercharge your tattooing game with the FK Irons Refuel Charging Dock. Keep your PowerBolts ready to roll at all times. This dock can power up two PowerBolts simultaneously, making it a must-have for long days at the shop or while working conventions. While you're using one, the others are getting juiced up and waiting for action. Plus, you get a steady, non-slip surface with a magnetic, anti-skid base for the most stable setup possible.Complete with LED indicators, the dock shows you a red light while your batteries are charging and a green light when you’re fully charged. The charge time is only 2-3 hours. For a top-notch performance, use the included Darklab wall adapter and USB-C cable. Make sure your battery pack's female USB-C ports match up with the dock charger's male ports for a perfect fit. When removing the battery pack, lift it straight up to avoid any connector damage, and steer clear of shaking it side-to-side. Keep it simple and power up hassle-free.Refer below for all machines using PowerBolt battery packs compatible with the Refuel Charging Dock.
