CrossingTech →The CrossingTech WOHW V2 by CrossingTech is the wireless evolution of the One Hit Wonder. With a battery-powered wireless heater, it offers full portability while maintaining the same ruby ball convection technology. Dual mode: wireless or with PID controller for precise temperature control. Compatible with all CrossingTech bowls and heater housings from the V1 system.
The WOHW V2 uses a 25mm heating coil (vs 20mm on V1) for faster heat-up and better heat distribution. Available in verified shops on our price comparison.

Wireless Freedom: Cordless or with PID
The heart of the V2 is the wireless heater: a battery-powered heating element that frees the WOHW from cables. Load, power on, draw — no PID controller or outlet needed. Ideal for balcony, garden, or on-the-go use.
In dual mode, the V2 can also be used with a traditional PID controller. This provides precise temperature control for sessions where accuracy matters. Switching is simple: remove the wireless heater, connect the coil to the PID.
The wireless heater battery lasts for multiple sessions. Charging via USB-C.
25mm Heating Coil: More Power Than V1
The V2 uses a 25mm heating coil instead of the V1 20mm. The larger coil offers two advantages: faster heat-up time and more even heat distribution across the ruby balls.
The 3mm ruby balls in the SS316 stainless steel or titanium housing are identical to V1. Heat capacity is sufficient for powerful single draws, even in wireless mode.
Heat-up time: approximately 30-45 seconds wireless, about 30 seconds with PID.
Full CrossingTech Ecosystem
The WOHW V2 is fully backward compatible with V1 accessories:
- Bowls: Original Glass, Micro Matrix, Titanium Matrix, Microdose
- Housings: SS316 Stainless Steel, Titanium (Standard + Gem-Cut Edition)
- Controllers: Classic PID (Single), Dual PID
- Bubblers: Chugga-Jug 2.0, Tower Bubbler, Mini Bubbler
Existing WOHW V1 owners can reuse all accessories. Only the heating coil is V2-specific (25mm vs 20mm).
Who Is the WOHW V2 For?
The V2 targets ball vape users who want portability without sacrificing desktop-quality performance. Comparison:
| Feature | WOHW V1 | WOHW V2 | Ruby Twist Pro |
|---|---|---|---|
| Wireless | No | Yes | No |
| PID Mode | Yes | Yes | Yes |
| Heating Coil | 20mm | 25mm | 20mm |
| Housing | SS316/Ti | SS316/Ti | SS316/Ti |
If you always vape at your desk, the more affordable V1 or Ruby Twist works fine. For flexibility, go with the V2.
