The Sandwave from CCELL is a Variable Voltage 400mAh Battery. The drop-in magnetic connector is compatible with 510 carts. The inhale activation allows you to draw without worrying about buttons. Switch between your three pre-set temperatures with the slide switch. This allows you to go between 2.8-3.6V and choose between intense flavour, powerful hits or something in the middle (the best of both worlds if you will). The sleek design and cool textured silicone let you get a grip for an ergonomic hold. Power up with a USB-C charger.
