Oumier Wasp Nano RTA Review

Here’s a look at the latest RTA released by Oumier Vape: the Oumier Wasp Nano RTA. It’s based on the classic and extremely popular design of their iconic Wasp Nano RDA and uses a near identical deck to the original RDA but now comes in a rebuildable tank format.

Oumier Wasp Nano RTA Features and Specs:

  • 23mmx35mm
  • PCTG Drip Tip
  • Top-Filling
  • Single coil
  • Double side airflow
  • 2ml Capacity

Oumier Wasp Nano RTA Packaging and Contents:

The Wasp Nano RTA comes packed in a nice little box. With an image of the tank on the front and some basic info on the back. In the kit, you get; the Wasp Nano RTA, a bag of spare that includes a set of extra o-rings, a handy t-shaped multi-tool, some spare flat-head grub screws and a pre-made coil without any specs. You also get a user manual, a bag containing some organic cotton and a spare glass tank.

I’d really like to see the pre-made coil included have some specs but other than that there isn’t much to complain about. It’s a decently stocked kit that contains all that you need to get started.

The Tank:

The tank is quite small. It’s a 23mm diameter tank which is a bit of an unusual size but considering most devices these days support atomizers bigger than 22mm it’s likely not an issue for most.

At the top, it comes equipped with a clear PCTG top cap/drip tip combo. It’s clear on the SS version I got but it’s also available in Black, rainbow, and gold with the caps changing color to match. The cap works great for top filling and is nice and comfortable on the lips however I have some concerns with the fact that the threads on it are also plastic.

The Tank Continued:

It’s also not an easy off cap so it takes a few turns to remove it. To me, it increases the chances of cross threading the cap which would render the whole thing useless. So far it’s been fine and I’ve been extra careful to thread it on properly but it still should be noted.

The tank itself is made of stainless steel and holds a pretty paltry 2ml of liquid. It might not seem like a lot but this is a dedicated single coil atomizer so 2ml tends to last quite a while unless you build it with a particularly thirsty coil.

It’s also a bottom adjustable airflow tank with three wide cyclops style lots around the base that can be opened or closed by turning the AFC or airflow control ring. I feel it’s almost a bit overkill to have three slots as the airflow at full open is actually restricted by the path the air has to take to get up to the deck so having three slots isn’t really necessary. The AFC ring has stops at either end and once screwed on to a mod likely won’t be moving around easily.

The Deck:

Popping off the tank we’re greeted with a near identical deck to the one we saw on the original Wasp Nano RDA. Angled airflow comes in from either side to hit the coil dead on from the sides cutting up and through what are essentially the posts of the deck.

Speaking of posts the Wasp Nano uses an interesting open side clamp style which makes popping in coils really easy. Leads are secured on either side with smallish flat head grubs. The heads of the grubs are a bit tapered which makes them a bit more prone to slipping when tightening things down. So far they’re holding up fine and they also include some spares so I should be alright but I know some people aren’t fans of flat-head grubs for this reason.

Build, Wick and Performance of the Oumier Wasp Nano RTA:

Thanks to the deck, building on the Wasp Nano RTA is as easy as building on the original. The open-sided clamps make dropping in a coil a breeze. For me, I like to slide the coil in on an angle. Then give it a turn to trap the leads and tighten down the grubs.

When it comes to wicking before you would just tuck your cotton down to the deck. There are now two rounded cutouts where you can direct your wicks. They open up to the bottom of the tank in a sort of GTA or RDTA style manner. You’ll want to make sure you don’t overstuff them. Or you’ll have trouble getting the chimney back. But both building and wicking on the Wasp Nano RTA should feel familiar and comfortable for most experienced vapers. Especially anyone who’s tried the original Wasp Nano.

The performance will obviously depend on how you build it but I popped in a simple fused Clapton and it’s been working an absolute treat.

The flavor is full and the airflow at full open is pretty much exactly how I like it, a slightly restricted direct lung vape.

Oumier Wasp Nano RTA Pros & Cons 

Pros:

  • Looks
  • Build quality
  • Ease of use
  • Single Coil
  • Compact size
  • Build deck

Dislikes:

  • Plastic top cap/threads
  • Tapered flat head grubs

Overall:

There really isn’t much not to love about the Oumier Wasp Nano RTA. As a fan of the original Wasp Nano RDA, the Wasp Nano RTA just makes sense. I love how easy and accessible the deck is to use. The flavor and airflow I get from it are ideal and I must say the tank just looks fantastic.

The plastic cap and flat head grubs are hardly a complaint but if you were a fan of the original or are just looking for a decent direct lung flavor RTA then I’d have no trouble recommending you check the Oumier Wasp Nano RTA out.
