Cheetah print on the outside and long battery life on the inside. This STIIIZY Pro XL has a 550mAh battery, the largest in the Pro lineup. Pop in a STIIIZY pod and draw, or press the button if you'd rather. Choose Low, Medium or High power, and use preheat to warm the oil before your first pull. The LED keeps you posted on battery and settings. Charging is USB-C. Wipe the pod connection now and then with a dry cotton swab to keep the contact clean.
