VLS Vector RDA

Vector RDA Intro

The Vector by VLS (Vapour LifeStyle) is an attractive and affordable new RDA built with a quality and attention to detail typically reserved for RDAs twice its price.  It is a product from the same Japanese company that brought our community the much-regarded Vulcan RDA and the Ragnarok mechanical mod. VLS products are primarily known for two things: quality craftsmanship and affordability.  With their latest offering, VLS has again given us vapers access to such a product.

The Vector is a 22 mm (diameter) RDA with a mini-profile and top-fed airflow that is designed for dual coils. For similarly constructed RDAs, The Vector by VLS houses a slightly deeper-than-average juice well and it comes with a proprietary, solid-state “super wide-bore drip cap AFC” (a drip tip/cap/airflow controller in one).  Inside of the tip there is a removable mesh screen to minimize hot spit-back. The airflow controller itself is highly adjustable with eight vertical air-inlets (four on either side of the base of the drip cap, controlled in tandem) that are positioned to be directly above the coils.

Vector RDA Specs and Features

  • The Vector by VLS
  • An allen key
  • 3 spare o-rings
  • 3 spare socket head screws
  • 2 spit-back mesh screens

It is my opinion that although VLS does include all those little parts that we often need extras of, this should be a standard in our industry and it is not!

  • Full 303 stainless steel
  • Single solid-piece construction
  • Vertical top-feed air intake
  • Super wide-bore AFC drip cap
  • Leak-free design
  • Signature under-passing juice well
  • Large post holes
  • ‘Squircular’ center post base
  • Pure red copper contact
  • Peek insulator
  • Unparalleled machining
  • Intended for advanced user only

Notable Remarks


Obviously the build matters a whole lot here! But I can say that if you can do a good dual-coil on another RDA, you should be able to experience fantastic flavor with this one.  I’d say for all the RDAs I’ve owned or used, it’s about in my 90th percentile for flavor from RDAs.


Same with vapor as with flavor — almost.  It really depends on how you build it and have the airflow set. Wide open, The Vector has a lot of airflow. I didn’t think The Vector by VLS would be capable of producing as much vapor as it can, but it’s still not what I would consider a cloud-chasing atty. It’s better described as a flavor-chasing atty that can produce dense clouds.


Most RDAs of its price range (or in general) aren’t as clean and well-built as The Vector.

  • The logo on the cap is etched nicely (as is the atty’s serial number that is on the floor of the juice well)
  • The deck, the cap and the drip cap AFC fit snugly with each other (and VLS uses quality o-rings)
  • I can pick up my mechanical mod by holding the drip cap, yet it takes little effort to take the cap off to access the coils when you need to (that’s a very good thing)
  • The large post holes of the deck are perfectly aligned and the (M6) socket head screws don’t easily back out when trapping wires
  • No spinning posts here due to the center post having a “squircular” base
  • No machine oil was anywhere on the atty
  • Nothing wobbly or of any concern with screwing it on the mod
  • Very clean and precise machining

As seen in the specs, the Vector RDA by VLS is made from a single, solid-piece of 303 stainless steel.  From what I gather, part of the reason this atty fits perfectly together is because that’s how it began, as one piece.

Build Deck

VLS Vector RDA Deck
VLS Vector RDA Deck

A three-post build deck that has a center post with a square base (“squircular”) and negative posts that sit on the edge of the deck (the “under-passing juice well”).  Since the negative posts don’t go all the way to the floor of the deck, that allows more space for liquid.

The three-post design is relatively straight forward if you’ve ever used one, but due to the air inlets being near the edge top of the top cap, you may want to build your coils toward the edge of the deck to ensure they get hit fairly directly by streams of air.  Obviously you shouldn’t go so close to the walls of the cap that your coils touch them (that could result in a short!); just build it close to the walls, but be safe. (The air inlets are where they are on the top cap because of how wide-bore the tip is.)

Since the airflow is only set up to accommodate dual coils, this atomizer is not intended for normal single-coil use unless you don’t mind having air on one side hitting empty space (which would also dilute your flavor from your one coil).  If you only like single-coil builds, this would be an issue.  (Maybe VLS could make a new cap that is designed for dual and single coils?)

Ease of build

VLS states this atty is for advanced users.  I think if you have experience with building proper dual-coils on an atty for what your mod and battery can safely handle, you should be fine (always meter it out to be sure).  I build mine anywhere from .3Ω to .8Ω in about 10 minutes from coil wrapping to vaping.

Drip Cap AFC

When using this RDA, you quickly get that its personality comes from this drip cap AFC (as they call it). Traditionally, RDAs come in two basic parts: the top cap, and a base/deck.  The airflow would commonly be on the sides of the top cap and can be adjusted there.

The Vector by VLS has three parts: a deck, a top cap and drip cap AFC.  The top cap houses the pair of vertical air inlets, but they’re on top of the cap.  [Note: VLS didn’t invent top-fed airflow.]  The two pair of air inlets are controlled in tandem by the top cap AFC. I keep mine at about 3 ½ open on each side.

A cool feature of the main cap design is that where the vertical air inlets are on the inside, there is a cut out between them. That cut out is spaced for the negative posts. That  cut-out allows the negative posts to lock into place with the cap so that you can easily unscrew the whole atty off the mod without the cap spinning around the deck.  That feature isn’t as useful on most mechanical mods with removable top caps as it might also remove the top cap of the mech.  But it’s no biggie, just hold the top cap while unscrewing The Vector if you use mechs.  You’re golden if you use regulated mods.


Fully open it has a lot of airflow (compared to what I thought it would have).  Simply turn the tip left or right to dial in your preferred setting.  According to VLS, the airflow is supposed to “scoop” up the vapor making the flavor more dense and rich.  I don’t know about the “scoop,” but it definitely feels different and tastes better than a lot of RDAs with side-fed airflow.  So maybe it is doing that sort of thing.


Fairly versatile.  But does it have to be more than that?  It does well at what it was meant for.  It’s a dual-coil atomizer with top fed airflow, large post holes and a somewhat deep juice well.  If you know what you are doing, you can have fun with it.


  • Inexpensive
  • Great for flavor even if you can only do basic dual coil builds.
  • Really good RDA for clouds
  • Virtually leak-free (unless you like to stand on your head while vaping)
  • Easy to trap wires
  • A relatively deep juice well aided by the “under-passing” of the negative posts
  • Large post holes
  • Nice-sized space for building
  • Easy-to-access coils
  • Snug fit on all parts
  • Easy to remove from the mod
  • Super wide-bore tip (if you are in to that sort of thing)
  • Full set of spares
  • Simple, but quality packaging
  • Well built


  • Not built for single coils
  • To build the coils directly under the air inlets, you have to have the coils set back a little close to the walls of the cap — that could be problematic for users of mechanical mods. The coils don’t have to be 100% directly under the inlets, so go for close and safe.
  • The tip of the drip cap is so close to the exposed air holes that you can cut off some airflow with your mouth. You have to keep your lips pretty close to the top.
  • Due to where the airholes are located, if you try and blow on your ramping-up coils before the inhale, all that hot vapor is going to hit you right in your face. This is not the atty to do that with!  I accidentally did it out of habit (I no longer have that habit!).
  • The screens to prevent hot spit-back do work for hot-spit back, but liquid will collect there and gets easily sucked back up if you’re taking a big hit (not a lot, but enough to notice).  I don’t like the screens for that reason, so I just popped them out.  But it’s just sort of a band-aid and really a missed opportunity for engineered innovation.
  • You cannot use your own drip tip
