Oumier Wasp Nano RTA

The amazing and tiny single coil RTA from Oumier!

Share on:

Having read back through my review it’s clear to see I cannot fault this superb RTA, I think Oumier should have come up with a new name as it’s a totally different vape to the original Wasp RDA.

Oumier have some great attys and often innovative, they really do their research and this release is one of their best, its simplistic contemporary design is visually pleasing and doesn’t look out of place on most mods I have used it on, though the 23mm diameter is a little odd so it slightly overhangs on 22mm mods.

Its main strength for me is its performance and flavour delivery at the lower power range, with the included coil I’m vaping it at 33.3 Watts (yeah OCD!) so it’s a win win, battery lasts longer, juice lasts longer and with its increased capacity it’s a great choice to last the day out and about.

The Wasp Nano RTA has got me back into RTA’s, though it can never compete with the current generation of stock mesh coils it still provides a different enough vape experience to belong in my daily vape collection.

Pros and Cons


  • Easy to build and wick.
  • Ingenious capacity hack (it can’t be an accident Oumier hollowed out the top cap).
  • Contemporary design.
  • Smooth airflow.
  • Excellent flavour delivery.
  • Compact size.
  • Cheap to run.
  • Coil & Cotton included.
  • Spares


  • Fixed drip tip (a con and a pro – see above)
  • No coil spec provided.
  • 23mm diameter overhangs on 22mm

Final thoughts and rating:

I thought the days of traditional RTA’s were over for me since I favoured Squonking RDA’s and latest tech Mesh Style stock coil tanks, this little Wasp has won me back into using an RTA on a regular basis, don’t expect it to beat Mesh for flavour but it’s close to RDA’s and a different enough vape to add to your collection if you fancy a change, I highly recommend this RTA.

Rating 8.5/10 – Close to perfection

My background is Engineering and Professional Photography. Mostly from POTV users knowledge I learned so much about pretty much all styles of vaping and equipment, Cloud Chasing, Squonking, Mouth To Lung, Direct To Lung, Pods, Mechs, Rebuild-able tanks and atomisers etc, and have experience with many many devices and atomisers, it's become a hobby and enjoy trying out the latest gear. I like to think my reviews are plain speaking and informative without getting too technical, if I have to resort to reading the manual then I don't consider it user friendly!
