Truly the first of it's kind, the eGo AIO features an all-in-one style that looks just as gorgeous as it performs. With the eGo AIO's all-in-one style, the tank and 1500mAh battery has been integrated together to create a seamless look. The innovative anti leak structures makes for zero leaking mishaps with it's unique design. A convenient top fill method allows the user to fill the 2mL tank with ease and the maximum fill line is indicated by either the max fill line on the glass of the tank or by the design of the secondary color of the unit. JoyeTech has added a flashy LED light into the tank which can be controlled to display a wide variety of colors (red, yellow, green, blue, indigo, white, purple). With the atomizer equipped with a child lock and a five button press battery activation, the AIO proves to be an ultra safe unit just in case the device is out of the user's hands. The hidden adjustable airflow is also located at the top of the unit for vapers to dial in on their preferred draw. On top of the adjustable airflow, the drip tip has been designed with a spiral structure for a smooth and controlled pull. Along with it's simple and streamlined design, the AIO is easily charged via micro USB.
