The Aspire Flexus AIO is an easy-to-use pod kit that supports both MTL (Mouth To Lung) and RDTL (Restricted Direct To Lung) vaping. The built-in 2000mAh battery will last most vapers all day, making this an ideal option if you’re looking for a reliable, everyday kit. The device will automatically detect which coil you’ve chosen and output the best wattage level, but for added flexibility you can also adjust the wattage yourself. Two coils are included to get you started – just add e-liquid.
