Should you buy the Core 2.0 / 2.1 E-Rig?

If you enjoyed the original Core Electric Dab Rig by Crossing, then you will absolutely love the Core 2.0 / The Core 2.1 with a V5 coil. We’ve had our sample for about a week now, and can give all the juicy details to you wax heads of the world about this great device. The first thing you’ll notice about the device is the metal housing that encapsulates the atomizer and its coils. This provides great support and helps the heat transfer within the unit to your dabs. It also makes cleaning a jiffy, as all you’ll need will be some vape cleaning sticks.  Due to the better housing, there will be much less splash, and we haven’t had to clean our coils this whole time.

As for the V5 coil (the same coil found on the DTV5), it is more than compatible with the original The Crossing Core and will pump out vapor on all settings. On the 2.0, you’ll have access to four power settings. The four heat settings are selected to optimize a healthy mix of flavor and huge clouds, as we’ll get into later in the review.

Is the Core 2.0 portable?

The base of the vape will fit very comfortably in the hand, and the bubbler will be about the same size to fit into the palm of the hand. With the now more secure atomizer and bubbler, you’ll be able to get hits with just one hand, and medicinal users shouldn’t have any problems getting anything to work either.

Core 2.0 Atomizer Vapor Quality

The heating system will be more than adequate to handle any kind of concentrate you throw into the ceramic-lined atomizer. Here’s a quick rundown of how it works:

  • The total session time for the Core 2.0 has been upgraded to 80 seconds, this includes the pre-heat time.
  • Blue will heat to 400° F / 205C in around 10 seconds
  • Green will heat to 425° F / 218C
  • White will heat to 465° F / 241C
  • Red will heat to 500° F / 260C in around 20 seconds

Less pre-heating and increased session times will let you get more out of your concentrates, and the vortex airflow in the spinner carb cap will let you visualize your dab experience.

Core 2.0 Battery Life

The 3150mah Li-Ion Battery Pack will last you about 50 sessions, or roughly an hour to an hour and a half of use depending on the heat mode you’re set to.  Charging with the USB-C port will take about an 1:45 to fully charge from dead, but you’ll be able to use a battery pack to help you boost portability.

The Core 2.0 vs the Original Core E-Rig

There are some things to note about the upgrades on the 2.0 which separate it from the Original Core. The new model has gotten rid of the wire-based coils to really boost its longevity and ease of cleaning as you won’t have to soak in iso to get rid of anything burnt. On that subject, there is also a heating mode designed to be used for cleaning – (red) with no product. For the atomizers, the PEEK plastic (medical / food grade) which you might be familiar with on the Mighty+, has been replaced purely with only metal and a ceramic-lined interior. The atomizer is now also completely rebuildable, so you won’t have to replace the housing as was the case with the Core 1.0, just the heater.

How to Use the Core 2.0 Vaporizer?

With the singular power button, you’ll have a variety of options to navigate. When you’re first learning the vaporizer, you might want to keep this list on hand:

Holding the power button will allow you to heat up the Core 2.0 for a maximum of 60 seconds.
Two clicks – Activate session mode – One click to cancel
Three Clicks – Change heat setting
Four Click – Display power level – Red/Low – White/Medium – Green/Full
Five Clicks – Lock or unlock Core 2.0 Base

For actual use on the Core 2.0, fire it up by pressing the button twice to activate session mode. For beginners, you’ll want to have a rice grain-sized dab on the heating element, and when this begins to bubble up, have the carb cap left off. When your device lets you know it has reached temperature with a vibration, place the carb cap back on and begin your hits, playing around with the carb cap when you want more or less airflow. If you still have some product left to clear after the 80-second timer, just restart it with the two clicks, and one to cancel it when you begin tasting a burnt flavor or are simply done.

How to get it running out of the box?

  1. After unboxing, make sure that you fully charge the battery to get the maximum lifespan out of the Lithium-ion
  2. Fill the bubbler from the top to the fill line, and then dry any external parts that may have gotten wet
  3. Place the bubbler into the base by making sure the vapor pathways align
  4. Thread your selected atomizer onto the base
  5. Attach the carb cap and tether for use during sessions
  6. Set your temperature (Recommended low to begin with) and enjoy a manual 60-second session, or 80-second pre-set!

How to Clean the Core 2.0 Vaporizer?

For cleaning the Core 2.0, the main thing to note will be cleaning out your atomizer with a cleaning stick, and any other areas when you begin to notice a resin buildup. Once a month or so, you can also get into the airway to keep it residue-free. Other than that, as long as you’re changing the bubbler’s water daily, and occasionally rinsing it out with iso and hot water, you’ll have no real problems.

The Core 2.0 Best Tips and tricks

We’ve found that the Core 2.0 is extremely easy to use in comparison to similar wax box mod setups due to the button display and finely calibrated pre-set temperatures, not to mention the coil-less atomizer. In our personal experience, pre-melting larger dabs and going past the initial haptic feedback (temperature reached vibration) allowed for bigger clouds. Hitting before the vibration, on blue or green, will also allow for more of a microdosing experience.

For ice hash, you’ll want to use the blue or green settings, and for more viscous and potent resins, white will be the better option. Red is quite harsh and we’ll need to do a little more research on how to better optimize that setting.

If you feel like you haven’t gotten all of the dab’s extraction, you can now just press and hold for a manual heat instead of having to start a second session. The manual heating also works as a pre-heat before cleaning to loosen up any resin buildups before you go in with a Q-tip.

If you extend your sessions for larger dabs, just a reminder that you won’t have to wait for haptic feedback to begin inhaling again after your two clicks because it will already be close to temperature.

For a more traditional dabbing style, you can have your vape already running hot from an empty session heater, and then add your dab to the atomizer on the second session for an immediate massive cloud hit that you’d be able to get from a torch-style.


Crossing SZ will provide a one-year warranty on all parts, excluding accidental damage by the user.

The Core 2.0 / 2.1 Review Conclusion

To conclude, we couldn’t be happier with the Core 2.0 / The Core 2.1 E-Rig thanks to awesome upgrades like the upgraded carber, v5 heater, and rebuildable ceramic atomizer. If you’ve been thinking about upgrading, the fact that the RDA V5 heater works with the original, and that the original’s coil atomizers will work on the 2.0 will be a huge relief for you. The design has been much improved on older models like the Puffco Peak, as the coils on the 2.0 have been supercharged to heat better, last longer, and also be more affordable. Stay on the lookout, as we’ll be bringing it into our store in the upcoming weeks.
