CrossingTech Core 2.1 — stainless steel housing, conduction, 205 to 260 °C. Narrow range? Intentional. This corridor targets maximum extraction without combustion. 13-second heat-up time. The 3150 mAh battery is one of the largest in this class, with pass-through charging included. Water pipe compatible. No gimmicks, no app required — a robust tool for users who know what they want.
In the price comparison, the Core 2.1 is available across 3 shops. The built-in bubbler eliminates the need for a separate water pipe adapter.

The Core 2.1 combines heating element, bubbler, and battery in a single device. Unlike traditional dab rigs, there is no separate torch, banger, or external power supply needed. This simplifies the setup considerably.
The integrated glass bubbler filters and cools vapor through water, producing smoother, cooler hits without the harshness of dry hits. The bubbler is removable for cleaning.
At 808 g, the Core 2.1 is not a pocket device but light enough to carry between rooms or to a friend's place.
The heating element uses conduction and reaches a maximum of 260 °C. Temperature is set via buttons on the device. Multiple presets allow quick switching between low and high temperatures.
Lower temperatures (around 180-220 °C) emphasize flavor, while higher settings (240-260 °C) produce denser clouds. The sweet spot for most concentrates sits around 220-240 °C.
Heat-up time is short, typical for e-rigs in this class. Passthrough charging is supported so the device can be used while plugged in.
The 3150 mAh battery is built in. The capacity covers numerous sessions in an evening. Passthrough charging means you can keep dabbing even at low battery.
According to the manufacturer, a full charge takes approximately 105 minutes. For home use, the device can stay on the charger permanently.
The integrated glass bubbler is the Core 2.1's defining feature. Water filters particles and cools vapor, noticeably reducing throat irritation. Water level is indicated by a marking on the bubbler.
The bubbler detaches for separate cleaning. Warm water and occasional isopropyl alcohol keep the glass clean. Replacement bubblers are available if the glass breaks.
The CrossingTech Core 2.1 is available across 5 shops in the price comparison. Prices vary by retailer and included accessories. Comparing before buying is worthwhile.
Alternatives in the e-rig category include the Puffco Peak Pro (significantly pricier) or simpler wax pens without water filtration. The Core 2.1 sits as an affordable middle ground with integrated bubbler.
The Core 2.1 atomizer is removable for cleaning. Isopropanol and a Q-tip handle basic maintenance. Deep clean every 10-15 sessions by soaking the atomizer.
Rinse the bubbler with water after each session. For mineral deposits, use vinegar or citric acid. Seals last 6-12 months with normal care.
The Core 2.1 works with several CrossingTech atomizers out of the box. The stock quartz bucket handles flower and concentrates at lower temps, while the optional SiC (silicon carbide) insert heats more evenly and cleans up faster. A titanium bucket is available too for users who prefer rapid heat-up over flavor purity. All atomizers share the same 510 thread connection, so swapping takes seconds.
Same device type and a similar price; matching heating methods come first. Size and features may differ.
