The Core 2.1 E-Rig

As one of the top-performing E-Rigs on the market, is an upgrade over both the OG Core, as well as the Core 2.0. Instead of a confusing rebuildable atomizer with an included screwdriver included in the kit, the Core 2.1 uses a ceramic 3D atomizer that will more evenly melt your dabs down and be easier for the E-Rig to vaporize.

Clean Air Path

With a pure glass and aluminum air pathway, you can be sure that you’re not getting any unwanted non-premium materials that could otherwise affect the taste and quality of your vapor.

3D Ceramic Atomizer

With a newly improved larger ceramic atomizer than previous models, you’ll get a much more even vaporization from your dabbing experience! Compared to the coils on the OG Core, all you’ll have to do is use a vape cleaning stick after your session for effortless maintenance. “3D” refers to the coil that wraps around the ceramic glaze that will make for a 360-degree heating which is a big improvement over the hot spots that coils can sometimes have.

Pre-Heat or Cold Start

With the four pre-set voltage temperatures, you can choose between the colors blue, green, white, and red depending on how and how long you want your sessions to be. As well, you can choose to load the atomizer hot or cold as the wide temperature range of 205°C-260°C / 401°F-500°F will always have a happy ending for your dab!

Who’s the Core 2.1 best for?

The Core 2.1 is for anyone looking for a premium Electric Dab Rig with easy-to-use one-button functionality, a massive 3150mAh battery, and USB-C charging. Your sessions will be super consistent, and the glass bubbler will provide you with a lot of surface area for your vapor to cool down with before you inhale!

    Finally get to KICK THE BUCKET! No more quartz banger!

    I just want to hit the button and get medicated and faded. I dont need the dancing lights and goofy stuff.

    I love cold starts with the white setting! Drop the dab, double click… vibrate, nice slow draws. Get 4 to 5 milked out hits! Then grab a slick blacked out cotton swab dipped in iso to give the v5 heated ceramic bowl an easy wipe down and it’s ready to go for the next one! Very well made. Sturdy heavy base!

    Love it however the atomizer only lasted through less than 1/2 a gram of wax it’s now not reading it mostly used the bowl on greed/white setting probably have 10 hits through it / cleaned with qtip every time and it’s already down blinking red lights kinda frustrating.

      Hi Mike, is the threading in the atomizer clean? It might be flooded, which can be cleaned with a q-tip and iso. If not, it could be a warranty issue which we can help out with.

    I recently made the jump from the Puffco Peak Pro to The Core 2.1, and I couldn’t be happier with my decision. After a lackluster experience with my previous device, The Core 2.1 has truly blown me away with its exceptional performance and outstanding features.

    First and foremost, let’s talk about vapor production. The Core 2.1 elevates the experience to a whole new level, delivering dense and flavorful clouds every time. Unlike my Puffco Peak Pro, which sometimes left me wanting more, this device consistently provides satisfying hits that are smooth, full-bodied, and absolutely delightful. I can now enjoy the pure essence of my concentrates like never before.

    Another standout feature of The Core 2.1 is its impressive battery life. Compared to my old device that required frequent recharging, this vape rig can handle multiple sessions on a single charge, making it extremely convenient for on-the-go use.

    From the very beginning, the Tools420 team has been passionate, responsive, and genuinely committed to ensuring customer satisfaction. They provided clear instructions, helpful tips, and readily addressed any concerns or questions I had. Being part of the Core (AKA Sai / Crossing Tech) Reddit community has been a pleasant and enriching experience, with fellow users sharing valuable insights and recommendations.

    In conclusion, The Core 2.1 has far exceeded my expectations, providing a vaping experience that is truly unparalleled. It has outshined my previous device in every aspect, from vapor production and temperature control to build quality and battery life. I can confidently say that my upgrade was worth every penny and I highly recommend The Core 2.1 to anyone seeking a top-of-the-line vape rig that consistently delivers exceptional results.

    Big tips : 1. Do not over fill, if you overfill the water bubblers they will leak into the air chamber and into the base so make sure you fill your bubbler up just barely above the holes so 1 / 4th of the way. and hit it while it’s separate and off of your base. To make sure it’s safe before attaching the base.

    2: q-tip after literally every dab if you want your atomizer looking and functioning brand new.

    3: the small hole in the glass on the bottom that acts as the airway I mentioned above make sure that is aligned with the hole in the base.

    4: clean the bubbler every 24 hours and replace water.

    I am a long time medical patient, and I would like to start this off by saying I am not sponsored, nor did I receive any special deals this is a honest review from a long term medical patient, I paid full $170. I then bought the side mouth piece bubbler opposed to the stock (egg shaped) glass came. Reason for the side mouth bubbler is because it has more holes, more percolation, more airway, super smooth flow. I did try using the stock bubbler and it feels a bit too restricted in airflow for me. So definitely get the side mouth bubbler The reason I got the 2.1 is specifically for the newer atomizers that came out, there’s the ceramic 3D that it comes with that gets HOT all around MILKS and is super easy to clean. Literally just q-tip after your dab and the bowl looks good as new and I take mine hot, i use the white setting and press it twice let it vibrate let me know it’s ready, then I press one more to cancel, throw in the dab and double press again to restart the sesh mode, if you don’t want to fiddle with the sesh mode you can just manually fire it with the button by holding it. People who have questions about the atomizers, this 2.1 is reverse compatible and you can use any of the quarts, or titanium Attys and heaters that they used on the core 1 and 2 which are also compatible with the 2.1 so there is a lot of versatility. The 3D ceramic I’ve used about a dozen times in sesh mode and is still pristine and looking brand new, I also ordered a quartz atty for backup and haven’t tried it yet. Overall I am very pleasantly baked and euphoric and the vapor quality is very dense and thick and it can milk if you want clouds. You get a lot of flavor on green setting but if you want a mix of flavor and clouds I use white setting, it does have a red setting which I have not used yet and that is the hottest setting. It’s simple which is what I like, I don’t want to have to use my phone and connect to an app and fiddle with all that I like the simplicity of just hitting one button and it heats up super fast, like within 10 seconds it will get you to your desired temperature. For the price, this thing is fucking amazing. I hope I did not skip any parts as I am high asf and if I skipped anything please ask, I got back to this way sooner than I should’ve but was super eager to review this for you guys. Oh, almost forgot, the vortex aluminum carp cap I was skeptical at first and didn’t want it to use it but I gave it a try and it actually makes my terp pearl spin like crazy I mean you can feel the terp pearl vibrate the atty that’s how well it makes it spin, so definitely 10/10 on the new carb cap overall score is 10/10 perfect af. It also has warranty for around a year if anything goes wrong.

    The V5 atomizer kicks ass. The clouds are real compared to the other E-Rigs I’ve had in the past. They could have changed the design more, but I don’t mind the fact it’s non rebuildable since you would have never found me with a screwdriver in my hand anyways.
