Small enough to wear, powerful enough to replace your desktop rig. The UBOX Plus is a palm-sized 510 battery that pairs a 500mAh cell with four voltage settings, preheat mode, and a clever trick most minis can't pull off: a built-in 10mm/14mm adapter that connects straight to your water pipe for smooth, filtered draws. Compatible with all 510-thread CBD cartridges (0.5ml, 1ml and 2ml), it charges fast, vapes while charging, and comes with a lanyard so it's always within reach. At just 28g, you'll forget you're carrying it — until you need it. Why we like it: Fits all 510 CBD cartridges up to 12mm diameter 4 voltage settings (2.6V / 3.4V / 4.0V + cycling mode) — one more than the original UBOX Preheat function for thicker oils 10mm & 14mm water pipe adapter included for bubbler-smooth hits Pass-through charging: vape while it charges Short-circuit protection & auto shut-off after 180 seconds idle Ultra-portable: 57 × 31 × 17mm, just 28g, lanyard included Quick start: Remove the shell, screw in your cartridge, replace the shell, then click the button 5× to power on and 3× to cycle voltages.
