    Ruby 21 21700 Mech MOD Kit by Kennedy Vapor

    The Ruby 21 is the latest innovation from Kennedy Vapor and their purest expression of unbridled and ultra-efficient vape performance. Featuring a one-piece design hearkening to the designs of early mod mods by fusing the chassis directly to a Kennedy 2-Post build deck, completely circumventing the cumbersome connection provided by ordinary threading and utilizing an atomically bonded connection for unreal voltage drop, asserting its dominance as the competition mechanical vaping platform of choice. Utilizing a thoroughly sporty form factor to accomplish both efficient transfer of power as well as catchy aesthetics, the solid metal chassis sculpted from your choice between stainless steel, brass or copper pushes nothing but pure, proper, punch-for-punch power to installed atomizers for peak performance from every draw. The self-adjusting copper contact allows for the use of either 21700 or 20700 battery cells for perfect versatility and compatibility with your current collection of cells.

    NOTE: This is a one-piece designed device, meaning the Deck is not removable from the tube.

    PLEASE NOTE: This is a direct battery contact device and it is strictly for ADVANCED USERS ONLY! Use at your own risk! This mod does NOT have a locking mechanism, so keep it away from children! Mechanical mods are an advanced user product and should not be used by anyone without proper knowledge of your battery's amp limit and how to test your atomizer's resistance. Please be careful when disassembling your mod. Be sure to check your atomizer's 510 connection. If your atomizer's 510 connection does not protrude long enough or if it does not have an adjustable center pin, your device may not fire. Avoid using your device to the point where the batteries are completely discharged. Always double-check the resistance of your atomizer on an external ohmmeter, and ensure that your batteries are inserted correctly with the poles at the correct position.

    IMPORTANT NOTE: Rebuildable Atomizers (RBAs, RDAs, etc.) are ADVANCED USER PRODUCTS and ARE NOT recommended for average users or beginners. The use and knowledge of how to properly test for shorts with a multimeter is a very important factor when building your own coils and wicks. WE DO NOT OFFER ANY WARRANTY, REFUNDS OR EXCHANGES ON ANY REBUILDABLE ATOMIZERS DUE TO THE NATURE OF THESE PRODUCTS.

    1. Amazing performance all-in-one mech kit  star rating

      Posted by Richard Hursting on 12th Sep 2019

      After already owning a Vindicator 21700 for a while, I pulled the trigger on the Ruby 21 because I wanted another ''vindicator'' but I planned to use nothing but a Kennedy RDA on top.
      So when I saw this device it was perfect, a ''Vin'' with a built in Kennedy 25! Plus the added bonus of lower voltage drop. This does make it tricky to build because you can't check your ohms before/after coil installation unless you assemble your coils on a different RDA and glow them there first- so with that I don't recommend it to mech-mod beginners.
      I got the cerakoted copper and the finish is amazing and gives good grip. The design of the constant contact switch is very easy to maintain and clean with no tools necessary. The 2 post deck is easy to build and accommodates most of my builds. All in all the mod hits hard and the RDA has spectacular flavor. Recommended to any experienced mech user.

    2. This mod has replaced everything I own.  star rating

      I was very hesitant about stainless mech mods. I never had good experiences in the past but I took the chance with the Ruby and this thing still hits like a champ, I'd say it hits harder than some of my parallel boxes. The button assembly is by far my favorite feature, I prefer using the longest throw but I definitely reccommend trying all three!

      Final Verdict: I could not live without this thing.

    3. HOLY S*** THIS THING IS AMAZING!!!  star rating

      I just ordered this stainless steel Kennedy Ruby 21 setup last week, and it arrived in the mail Saturday morning. I just got into higher end mechanical mods a few weeks ago, so the only other one I have is a Purge Back to Basics V4 kit. Honestly I like this Kennedy Ruby 21 more than my Purge.

      When I first opened my Kennedy I thought they must have sent me the wrong thing, because I couldn't believe how much smaller and lighter it is than my B2B! I can easily carry this around along with a bottle of liquid in my pocket. It vapes like a dream.

      So far I have only used one build in the device, which is a pair of Feenz brand framed staple coils that are supposed to be between 0.11 and 0.13 ohms (per pair) with Firebolt cotton. This should be safe to use with the Samsung 30T 21700 batteries I have, and so far is working great!

      A few years ago I had the Geekvape Tsunami 24 glass window RDA, which is similar to the Kennedy design. It also had the two air tubes on each side that drew air up to each coil. I don't know if it's just because this RDA that is included with the Ruby 21 is 25 mm diameter or if it's just way better than my Tsunami was, but I've found a few things I really like better about the Kennedy.
