Daily Deal
Daily Deal


MaxVaping's second generation of the popular Cumulus atomizer. This design has a two-post base (Velocity Style) with huge airflow (Freakshow Style), and a glass shell top. SS and glass caps are also available here. Caps fit all versions of Cumulus Maximus.

v1 Includes:

  • Atomizer with Glass Shell Cap
  • Spare clear glass cap (You get two glass caps in the v1 kit.)
  • Extra headless screws, two coils, spare o-rings, Allen wrench (regular) or screwdriver (v1p)
  • Version v1p has Phillips head grub screws.
  • NOTE: You can block one air hole with cotton, if you are running in single-coil mode and prefer restricted air flow.
v2 Includes:
  • Atomizer with Glass Shell Cap
  • Black or Silver Stainless Steel Cap
  • Extra headless screws, two coils, spare o-rings, screwdriver
  • Airflow adjustment ring.


  • SS Cap (full kit plus add a silver stainless steel cap).
  • Glass Cap (full kit above plus add an extra glass shell cap).
NOTE: The glass cap is looser than the SS cap. That is by design so it can be quickly removed. If you find it too loose, dry the juice from the o-rings and inside of the glass cap, and it will be more secure. Also, the 22mm Fishbone RDA glass shell caps (many colors) fit the Cumulus Maximus, but they have the "Fishbone" logo.

    Cumulus Maximus RDA

    Bottom airflow, sealed off juice well and sweet glass cap! What's not to like? Only 4 stars because I haven't actually used it yet, but everything looks and feels well made, has plenty of airflow (for me anyway) and both caps fit snuggly without putting up a fight. I plan on using it as a single coiler, but even if it needs to have 2 to work well I have no doubt that I can find the right build to produce all the flavor and clouds I could hope for. I'll match up a squonk pin from one of my other devices for it, even if I have to file one down a bit. There's really no sense (to me) in spending 4 or 5 times as much on such a simple device...for what this is...the price is right.

    Fantastic rda

    Amazing rda, great build quality, tons of airflow. I would buy this rda again and again. Love the build deck. Awesome choice for beginners as experienced vapers alike. Well worth the money!

    a lil disappointed

    was excited to receive this rda. the glass bell broke in the first 5 minutes. a lil disappointed in the quality of the glass, but the flavor this thing produces is great. I give it a 7 out of a 10.

    Cumulus Maximus RDA.

    Is a very nice deck. Was very clean right out the packaging, no machining oil. Deck is easy to build on. The top cap allows plenty of space for the coils. Enough room that you could easily put four coils in it. Plenty of airflow. Bottom airflow aids in the strong flavor this rda gives off. Currently have a .3ohm build and at 100watts the flavor is amazing. Both the metal and glass top caps fit nice and snug. I honestly have no cons to report on this RDA. Will definitely recommend to others.

    Cumulus Maximus RDA

    Please don't try to tighten this RDA down with the posts, it loosens the post making for a possible short like happened to mine Otherwise, its a good RDA that you can install large coils on. I just messed up.
