Crossing Technology Core Series eRig (Core 2.1 and Core 2XL)

The Crossing Technology Core Series includes two portable, all-in-one eRig variations designed for concentrate use (not intended for dry herb): Core 2.1 and Core 2XL (Core XL). Both combine an electronic base, a glass bubbler for water filtration, and a heated cup-style atomizer setup in one compact system.

Core 2.1 Overview

The Core 2.1 pairs a compact base with a borosilicate glass bubbler and a fully heated ceramic cup-style heating surface. It uses simple one-button controls with four heat settings, a rebuildable atomizer, and an isolated aluminum-and-glass vapor pathway. It includes safety protections and a USB-C rechargeable 3150mAh battery pack.

Core 2XL (Core XL) Overview

The Core 2XL (Core XL) is a portable eRig option within the Core family that uses an integrated 3D-style atomizer chamber and glass bubbler. Core XL kits/variants commonly reference upgraded glass options (including joystick-style caps in some versions) and higher-flow bubbler designs.
