The Vaporesso ECO NANO 2 is a fill-and-go refillable pod kit with a 1000mAh battery and fixed, auto-adjusting output rather than variable wattage, using a 4-level LED battery indicator in place of a screen. It takes 6mL bottom-fill pods (0.6–1.2Ω) and charges over USB-C. Vaporesso's COREX Smooth heating keeps flavour consistent across the full life of each pod.
