The mod has a built-in 2000 mAh battery for all-day vaping and can output 5 to 40 watts of power. For less experienced users, the mod\'s Smart Mode helps take the guesswork out of wattage settings by recognising the resistance of the coil being used and setting the recommended wattage. The lower power range is ideal for Mouth-to-Lung coils while the higher output should be used with lower resistance mesh coils. A 0.96 inch OLED screen means information such as resistance, puff count and wattage is clear and easy to see. The mod uses USB-C charging to shorten charge times. The included GTX Tank 18 boasts adjustable air-flow, which allows you to choose between an airier or more restricted vape style, as well as convenient top-filling and a push-pull system for quick and easy coil changing.
