The Orchid RBA has the same tank and chimney design as a Kayfun, the main difference between them is that the Orchid is designed for dual-coil builds instead of a single coil build like the Kayfun. The top cap has heat sink fins to help dissipate heat from the device and the v4 has a new tank design that looks exactly like a kayfun tank.

The base of the RBA has an adjustable 510 center pin and a screw fill-hole to easily fill up the tank. The deck has 4 wire terminals for dual-coil build and 4 wicking channels to ensure a wet wick. The Orchid V4 also features an adjustable copper 510 center pin.
