Oumier Wasp Nano S RDA

Hellvape Fat Rabbit RTA


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.

Best RTA yet! (04 March 2022)

I've been vaping for 6 years + now and I've went through a few RTA and RDA atomisers over the years but this one is the best yet. The design, set up and user experience is easy, clear and simple. The screw points to fix your coil on to the mount beds are brilliant, nice little hooks to stop your coil wire from going loose or slip out The mouth tip nice to vape on with brilliant flavour everytime, easy to unscrew and quickly to refill as well. Plenty of air flow if the 3 vents are open full and even good flow if half opened. Every time a new coil and wick is set up I've not had any issues with leaks spillage at all. Best RTA, I'll only be buying premier products in the future.

Excellent single coil RTA (03 November 2021)

Great flavour and cloud production from this small RTA, suited for fruit flavours rather than custards/deserts which "pop" more on a dual coil set-up. Delivered overnight with fantastic free bubble glass gift from vape club.

One of the best tanks I've used (01 November 2021)

Absolutely fantastic. Very nice to build on and the flavour is superb. If you fill the tank from the top as usual and then turn upside down, unscrew the base and fill from the bottom you get double the capacity! I was blown away by this tank and haven't had any leaks or dry hits. Get one, you won't be dissapointed

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!
