Welcome to The Needle Parlor!
Darklab's fast-charging 6-foot extended USB-C cable comes with a charging block and will help maximize the output of FK Irons' machines, as well as prolong the battery life. We recommend purchasing the USB-C charger as an add-on with all device and power pack purchases for optimal, long-lasting mechanical functionality.
It works great. I have a Spektra flux s and thought my machine was damaged, but just needed the right charger. I plugged it in for a little bit and it turn right back on.
