Product Description

RDTAs have never been easier to build on than with the Oumier Wasp Nano RDTA (Rebuildable Drip Tank Atomizer). Crafted from stainless steel and almost seamless in design, this single coil RDTA is compact, super easy to build on, and a delight to use! Coming with a standard adjustable airflow, this unique tank also has top-fill capabilities literally in the build deck, making it a breeze to refill. The diminutive 2ml tank holds just enough juice to keep you going for a little while and switch up to try something new later on! 

This Oumier RDTA is a nice standard 22mm atomizer with a big deck where your build sits directly in between your airflow, optimizing flavor and cloud production like no other. The ULTEM top cap makes for heat free vaping and works well when paired with a small bore 510 drip tip for those who prefer to control their intake. Another impressive feature of this RDTA is the sliding lever that closes up the juice intake to prevent leaking.

Not only does this tough but tiny atomizer produce solid clouds, it also works well on any mod you decide to use with it. Perfect for beginners all the way to experienced builders, the Oumier Wasp Nano RDTA is a solidly built, well-appointed device that will hold up well with your favorite single coil builds. 

Note: The colors for the resin option vary greatly, there is no way to tell which color you get until you open the box.

  1. Best flavor & easy set up

    Posted by April clem on Jun 4th 2018

    I'm so impressed with this little guy! Easy coil building & just open the sliding pen to fill bottom tank holding area. Same amount of smoke clouds as my previous limitless rda that has dual coils! Best buy (yet) ever! No complaint but don't hit repeatedly or it will be warm on the lips.

  2. Loving it!

    Posted by David Trethewey on Apr 3rd 2018

    Great little RTDA! Easy to build. Can be a little tricky to fill without leaking. Would highly recommend it!

  3. Love this beast!!!!

    Posted by Gerry H on Feb 22nd 2018

    I wanted to change from a regular tank to a buildable, and this is a great starter! I’ve actually purchased a second one because I love it so much. Easy to build, flavor is unreal, and nice cloud production if that’s what your looking for as well. I highly recommend the wasp nano rdta to anyone in a heartbeat!

  4. Great Small RDA that is on top of a Tank!

    Posted by Kiefer Lester on Feb 18th 2018

    I am using this as an RDA when at home and as an RDTA for when I leave. I am using the tri-core fused clapton(0.39 ohms) 3mm ID that came with it and it produces major flavor and vapor for being a single coil build. All my ADVs that was great before are now phenomenal tasting! Coming from a baby beast tank with RBA unit that has dual braided 30 AWG (0.285 ohms) 2.5mm ID. I will definitely be recommending this little RDTA for anyone looking for a small and flavorful vape.

  5. Flavorful Cloud Beast

    Posted by David on Jan 31st 2018

    This little thing is on point. Easy to build,easy to fill. I'm enjoying it very much. Great flavor and vapor!

  6. Great TINY little RDTA

    Posted by Sam C on Jan 19th 2018

    If you have ever used the Wasp Nano RDA, you know how great the flavor is, since it's a tiny RDA that is MADE for single coil builds. This is exactly the same, but with a 2ml tank. Great flavor and extremely simple to build. This would be a perfect first RDTA for someone new to them that wants to dip their toes.

    As far as filling goes, I simply use a 30ml needle tip bottle. Works great, easy to slide next to the cotton once you open the 'slot' a little bit. No problems.

    This is an incredible stealth tank. I always keep one wicked and ready to go. If I leave the house for a few errands, need to sneak a vape, etc it's great on a small single battery mod like a Pico. Many times when leaving the house if I don't want to carry a larger setup, I take this on a Pico and bring a small needle tip bottle in case I'm away longer than planned.

    Depending on your build, this thing will hit like a tank. Since the juice capacity is only 2ml, I usually just use a simple single coil wire (no aliens, etc) and you can get a nice vape without draining it dry in 15 mins.

    Everyone should have a few of these. If nice, it's a great vape for when I'm rebuilding other tanks, or just need something small to take out of the house. After my first one, I now have four, lol.

    This would be PERFECT if it had a squonk pin.

  7. Easy filling.

    Posted by Eric on Jan 18th 2018

    I've read in numerous places of the difficulty with filling the tank. It's all about technique. Keep at least one wick long but thin it out. Close that juice flow halfway on your first tankful. After that is easy filling. This rdta is my first buildable and I absolutely love it. I wanted the RDA but it's out of stock at the time of writing.

  8. Excellent flavor

    Posted by chuck on Dec 25th 2017

    This is my first RDTA (only used smok baby beast before this)
    and all i can say is WOW this little thing after the first 5 minutes of using has officially retired my tank ways..
    it was extremely easy to set up (i never built anything before this) as soon as i received 2 days ago i stuck in the little coil thats included along with the cotton used some sour double rainbow ejuice (which was also a first time for me) and have not been able to put this thing down so much so that my presteep sour rainbow is almost gone already :( lol .
    excellent flavor nice clouds and very simple and easy to setup (other than filling it up but once i did just moved the little rod to create a space that my dripper tip can fit in to refill.
    only con for me was not getting more of that sour double rainbow and extra coils/cotton so u wont have any down time.
    a winner for sure.

  9. Filling me with anger.

    Posted by Kyle Strachan on Dec 8th 2017

    Love the deck, flavor, and vapor production. Filling is a nightmare, such a mess. It's definitely not something I will be using on the go.

  10. Great For The Price

    Posted by Mike on Nov 22nd 2017

    My TFV4 junked out and I was dripping as my all day setup (which I didn't remember being quite as much of a pain as it actually is). I needed something for all day use and didn't want to put a whole lot of money into it. As mentioned on the other reviews, it can be a pain to fill. Trimming the wick and filling while at a tilted angle make it a lot easier to fill. Great flavor and extremely easy to build upon. Fits my needs just fine but could see the 2ml tank section being too small. But for less than $20, it's totally worth the money

  11. There's a trick to it

    Posted by Amy Cooley on Nov 21st 2017

    I've noticed that on this site and others that reviewers complain that the tank portion of the RDTA is difficult to fill. I found a trick for it on YouTube (sorry, I honestly cannot remember whose video it was but you can google it).

    To make filling the tank easier, when you build the coil, take the cotton on either side and thin and trim it before placing the ends in the tank.

    To thin the cotton, you can use a pair of scissors or your tweezers and run the sharp point through the cotton lengthwise. This will pull some of the cotton threads away from the bundle.

    To trim, simply take the cotton left in the bundle and squeeze it back together, then trim just a touch from the sides lengthwise (stopping at the coil or just before) and then place the ends in the tank.

    Close the "door" to the tank tight a few times to get the cotton to one side of the opening. Open the door fully, prime your cotton and, when the two side bundles are soaked, close the door again a few times. Open the door and the cotton should leave a nice opening for you to add your juice to the tank.

    If I can find the video again, I'll try to edit my review with a link or the name.

    Also: Don't leave the door open after filling, you'll get some nasty spit-back. Closing it tightly hasn't hurt it or the cotton and I have had great hits with this tank. My only complaint might be that this tank tends to have a lot of condensation build up but that may just be irritating to me and even then, only slightly so.

  12. Great with one but...

    Posted by Harley Nelson on Nov 20th 2017

    air flow
    dem clouds brah
    build deck

    filling is a pain.

    the slider is nice but you have to get it just right. too open and it leaks and spits. too closed and you will get dry hits.
