SEED battery has been under development for the past six months. It is a portable handheld device that fits discreetly in the palm of your hand. With its magnetic drop-in, it’s super convenient for switching out cartridges. Draw-activation requires no confusing instructions how to use, simply inhale and you will notice a soft vibration (haptic feedback) that indicates that the battery is working properly. The SEED was designed to work perfectly with AVD-brand cartridges and has two different heat settings for maximum flavor or maximum clouds.
