The Vaporesso GTX One vape kit is not only a good example of an entry-level vape kit, but it also features a variable output that allows it to be used as you progress and your experience grows. Powered by a large 2000mAh built-in battery it features a 40W variable output. Designed to support a mouth to lung vape style, discreet vapour production is assured thanks to the newly designed GTX 18 tank that features adjustable airflow and a 2ml e-liquid capacity.
