The AIO by Joyetech is an All-In-One system that, despite its size, is quite the performer. Even with its integrated 1500mAh Battery and Cubis Style, 2ml tank system the AIO measures in at 118mm in length and 19mm wide making it a very pocket friendly device. The One Button Design makes the AIO incredibly easy to use: 5 Clicks to power On and 5 Clicks Off. No power adjustments are necessary, as the AIO is fine tuned to work best with the included BF SS316 0.6Ω atomizers. Adjusting your airflow is as simple as the turn of a dial, and given its overall size, you will be pleasantly surprised by its vapor production. Additionally, the included Spiral Mouthpiece helps intensify flavor while eliminating spit back. The AIO utilizes an indicator light that illuminates through the tank viewing windows. The indicator light is available in 7 colors to give your AIO its own personality, or you can disable the light completely. One of the best features is the Childproof and Leak Proof tank. Using a CRC design, a decent amount of pressure is required to take the top off. To add to this already incredible safety feature, the AIO is also equipped with over-charge protection. Its petite size, ease of use, and safety features make the AIO a clear choice for any vaper.
