The Oumier Wasp Nano S RDA is a Rebuildable Dripping Atomiser recommended for advanced vapers. Featuring a single/dual coil configuration on a two post Stainless Steel build deck, it can be configured for both MTL (Mouth to Lung) and DTL (Direct to Lung) vaping. The Wasp Nano S can be paired with most vape mods via its 510 connection, while its bottom-feeding pin ensures that it can also be paired with squonk mods. Thanks to its 5mm deep well, you can do a lot of vaping between dripping.


  • Dual Post Single/Dual Coil Build Deck
  • BF 510 Connection
  • 25mm Diameter with 810 drip tip
  • Stainless-Steel Construction
  • 5mm Deep E-liquid Well
  • Side Airflow Vents To Side Of Coil
  • Slotted Top Cap Airflow Control

Made of Stainless Steel, the Wasp Nano S has a sturdy construction, and is both hardwearing and easy to clean. At the same time, it is easy to take apart and assemble, thanks to the smooth machining on the threads. The deck features 4 terminals, secured from the top, to accommodate two rebuildable coils. In a somewhat unconventional design, the posts are not linear but angled in such a way that the positioning of the two coils is offset rather than parallel, leaving space for the ends of the wicks of each coil.

The Wasp Nano S features big airflow channels, and the top cap turns continuously in either direction, without stops, to increase or decrease the size of the air holes. This makes it easy for you to adjust the airflow for a wider inhale to suit DTL vaping or a narrower air intake for MTL vaping. The Wasp Nano S is compatible with most vape mods, including squonk mods, thanks to the hollow 510 squonk pin supplied, that you can use in place of the pre-installed solid 510 pin.

Important information about Rebuildable Dripping Atomisers:

Rebuildable atomisers are recommended only for experienced users. You should have the knowledge and access to the equipment that is required to set up this atomiser properly.

Before building or using an RDA you should have a thorough knowledge of battery safety, Ohm's Law and vaping in general.

Before fitting a coil onto your rebuildable atomiser ensure it is in a safe condition and registering the correct Ohmage, this testing and checking can be achieved by using a dedicated Ohmmeter. Coils should not be tested on vape devices.
