Here’s Atmizone’s fresh take on how 510d-type tanks should function and look:
Meet the Bayou.
Featuring a unique screw-on cap design and an innovative, easy side-refill system, the Bayou is a robust, minimal tank for 510d cartomizers and 510d-type rebuildable atomizers.
The Bayou has been designed in a function-oriented manner to solve the most common issues associated with conventional tanks:
Screw-on cap design: The Bayou will never just pop open no matter how you handle it.
Closed-end, food-grade PMMA acrylic glass container: Keeps e-liquid fully sealed and isolated from both caps.
Close-to-bottom inner tank o-ring placement: For maximum capacity and compatibility with pre-punched cartomizers and 510d-type RBAs with supply holes close to their base.
Fast and easy re-fill: Topping up is done from the side of the tank using a 1.0-1.3mm needle-equipped container (supplied with the Bayou): Unscrew the cap, insert the needle sideways, refill, screw the cap back on, done!
High capacity for its size: Bayou S (35mm) – 2.5ml, Bayou L (45mm) – 4.0ml.
High compatibility: The Bayou comes with an extension ring for a flush connection when used with the Roller / Dingo and a Classic 510 connector. The extension ring increases the length of the tank by 1.0mm and can be also used with odd-sized cartomizers, or with any 510d-type atomizer, if you like its looks. The Bayou is also compatible with bottom-lock-equipped cartomizers.
Bottom cap with air-flow channels: The Bayou will not choke your vape even when sitting flush on your mod. It also provides basic air-flow control when used with the Roller or Dingo and a Classic 510 Connector.
With its 19.5mm external diameter, the first, compact version of the Bayou is a perfect match for the Guppy, our brand-new, 16340 uni-tube mini-mech. If you are a fan of small-diameter, lightweight gear, you might have just found the tank you’ve been looking for.
A 22.0mm version will follow shortly.



What do you recommend as the best cartomizer for the bayou?
Hey Baba,
We have experimented with smaller fuses for the Guppy and it seems that, in terms of absolute performance, it’s better to use a Black AW ICR 16340, which is 750 mAh and has a ~3A limit.
In comparison, the red AW IMR 16340 is 550 mAh and has a ~4A limit.
Hello,
For the carto I’ve never tried the boge or other brand but I just received my sweet “Sophia” (ΣΟΦΙΑ by leo) and it’s a great combo in my opinion.
The only thing i’m waiting for is a “Bug” for the guppy.
Enjoy
Hard to say, there are so many cartos out there and we’ve only tried a few! We’ve had good experiences with original Boge cartos, but you could also go for a 510d-type RBA, which you can set-up in any way you like!
Love the Bayou! Filling is a breeze!
On my wish list; a Bayou type tank with the same diameter as the Roller & Dingo!
Love my new roller…but it’s true, a perfect bayou fitting on it would be really nice !
Amazing tank. Cool that the bottom has air flow channels.
Just received my Guppy and Bayou in brass. Amazing. Perfect size for slipping into your pocket and the quality is outstanding. Ordered late Wednesday night and received first thing Friday morning in the UK. Superb product and service. My order for an SS Guppy already made…
