The Oumier Wasp Nano RTA is a Rebuildable Tank Atomiser designed for advanced vapers. Featuring a single coil build deck, it is well suited to MTL vaping (Mouth to Lung), although it can also be adapted to DTL (Direct to Lung) vaping. The Wasp Nano can be paired with most mods thanks to its standard 510 connector. The tank comes complete with a rebuildable coil and contains everything you need to get started.


  • 2ml E-Liquid Capacity
  • Top Filling
  • Adjustable Bottom Airflow
  • 510 Connection
  • Dual Post Single Coil Build

Every part of the Wasp Nano is sturdy and well-constructed, so configuring it is straightforward. Thanks to the generous spacing between the two posts, and also to the cut-out sides in each post, you will find it easy to install a rebuildable coil. A cleverly placed lip at the bottom of each cut-out prevents the coil from slipping while you’re installing it. Wicking is also made easy, thanks to the two wells. When the ends of the cotton wick are pushed into those wells, they bring e-liquid to the coils at a steady rate.

The airflow into the 2ml tank enters from two sides, rising up through the posts and emerging on both sides of the coil, for a greater inhale and better flavour. The airflow ring is easy to adjust, providing good control between a tighter or looser inhale, further enhancing your choice of DTL or MTL vaping. Thanks to sturdy threading, the top cap twists off easily to grant access to two large top-filling slots.

Important information about Rebuildable Tank Atomisers:

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

Before building coils or using an RTA 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.

Wasp Nano RTA (06 June 2021)

Brilliant little tank. I bought the gold version to match my mod. researched heavily what tank to buy as a beginner and decided on this. I wasn't keen on the included coil so put a 2.5mm 0.9ohm MTL coil in and wicked with cotton bacon v2. Taste, Vapor and ascetics, this tank has it all. not a single leak either. very happy with my purchase!
