WOHW Review: Wireless Ball Vape by Crossing Tech
The short version
The WOHW (Wireless One Hit Wonder) by Crossing Tech is a desktop ball vape with a heating head that detaches during the draw. The PID controller and heating coil remain connected to the power supply. The technical description in this article documents the original WOHW version with 520 ruby balls; the current V2 configuration is explained separately in the update below. This classification is based on product documentation and is not an independent lab or long-term test. Current offers are available in the price comparison: 293.26 € incl. shipping.
Hazekamp et al. (2006) studied the Volcano and its THC transfer. On average, approximately 54% of the loaded THC reached the balloon. The study examined neither the WOHW nor a blanket 95% reduction in harmful substances across all vaporizers. No performance or health claims for the WOHW can be derived from it. Hazekamp et al. (2006)

For the current WOHW V2, Crossing describes a heating head filled with 280 ruby balls measuring 3 mm, variants made of titanium or SS316 stainless steel, and a matrix bowl with 14.4 mm and 18.8 mm connections. The controller, docking station, and heating coil are included in the described kit. A water filter is required separately. The exact contents of the package depend on the selected variant; the older specifications of 520 balls do not apply to this V2 kit. The linked manufacturer description, verified on 10/06/2026, is the authoritative source. Crossing WOHW V2
Historical description: The following sections referencing 520 ruby balls apply to the original WOHW version. Compare these specifications with the specific current product variant before making a purchase.
What’s in the box?
Crossing Tech packs almost everything you need into the WOHW kit:
- Injector head made of titanium with wooden handle and 520 GemCat ruby balls
- Titanium bowl with wooden handle, screen and two glass adapters (14.4 mm and 18.8 mm)
- PID controller with digital temperature display
- Docking station made of aluminum with screws and hex key
- 25 mm coaxial heating coil
- IEC power cable, scoop, brush, spare mesh screens and Viton O-rings
What’s actually missing: a stir tool for mixing your herb between draws. Not a dealbreaker, but you’d expect one in an “all-inclusive” kit. And of course a water piece – that’s on you.
Setup and first steps
Before you can start, the heating coil needs to be installed in the docking station. The coil sits centrally with about 3 mm clearance to the edges and is secured with two small hex screws. Don’t overtighten them – hand-tight is enough.
After that, attach the base to the PID controller using the included rubber rings, tuck the cable into the channel and plug in the five-pin connector. Connect the power cable and you’re done. The whole setup takes maybe ten minutes.
The docking station in detail
The aluminum base isn’t just a holder for the heating coil. It also has space for accessories: three 18 mm holes, four 14 mm holes and two 10 mm holes. You can store bowls, stems and other gear neatly. Together with the PID controller, it forms a compact unit that’s easy to move around the house – almost like a portable desktop vaporizer.
The injector head: heart of the WOHW
Inside the injector head sit 520 GemCat ruby balls. They store heat from the coil and release it when placed onto the bowl. The head is made of titanium with a wooden handle so you don’t burn your fingers.
One feature that’s not common with ball vapes: the injector head can be placed in two orientations.
| Mode | How it works | Effect |
|---|---|---|
| Injector | Greater distance to the herb, more concentrated airflow | More targeted heat, slightly milder vapor |
| Showerhead | Closer to the herb, broader heat distribution | Denser vapor, more even extraction |
The two described orientations change the distance and airflow. This article does not include an independent measured comparison of their temperature distribution, yield, or flavor effect.
The titanium bowl
The bowl is also titanium with a wooden handle. A screen sits at the bottom and can be swapped out (two spares are included). The glass adapters (14.4 mm and 18.8 mm) are held by a Viton O-ring and can be changed depending on your water piece.
Beyond the standard titanium bowl, two accessories are worth mentioning:
- Microdose bowl – handles loads under 0.1 g far better than the full-size bowl.
- Glass bowl – for those who prefer the flavor of glass. Performs well too.
PID controller: stay out of the menu
The PID display describes the regulation of the heating coil and is not a measurement of the temperature at every point within the plant material. The current WOHW V2 manual from Crossing lists 535 °F as the recommended starting point for the temperature setting; this is not a statement about a factory setting of the controller. This is a model-specific manufacturer specification and not a general target value for other WOHW versions or controllers. Use the manual for your specific combination; do not change unknown control parameters. The dock and heating head get hot and require a suitable surface.
Using it in practice
Here’s what a typical session looks like:
- Switch on the PID and place the injector head in the heating coil
- Wait for the temperature to be reached (about 5 minutes the first time, faster after that)
- Place the bowl on your water piece and fill it with the scoop
- Set the injector head onto the bowl (injector or showerhead mode)
- Take a big draw
- Put the injector head back in the coil to recharge
Want thicker clouds? Place the bowl on top of the injector head during pre-heating. This heats the bowl too and adds a conduction effect.
Here’s the catch
The name says it all: One Hit Wonder. The stored heat in the ruby balls delivers one massive hit. After that, the head goes back into the coil to reload. If you want multiple draws in a row, you’ll need to wait between each one.
That’s not a flaw – it’s the design. A wireless ball vape doesn’t have continuous power like a wired model. The thermal mass of the ruby balls is finite.
Who is the WOHW for?
Good fit for:
- Newcomers to ball vapes who want a complete kit without sourcing parts separately
- Users looking for a compact desktop vaporizer that doesn’t take up much space
- Casual users who are happy with one big hit per heat cycle
- Budget-conscious buyers – the value for money is strong for a ball vape set
Less suited for:
- Vape enthusiasts who want to experiment with many different bowls and custom setups – wired ball vapes offer more flexibility
- Users who prefer long sessions with multiple draws back to back
- Anyone looking for wide bowl compatibility – the WOHW runs out of steam with bowls that create more distance from the herb
Wireless vs. wired: what’s the difference?
| Feature | Wireless (e.g. WOHW) | Wired (e.g. Breniix) |
|---|---|---|
| Heating | Coil charges ruby balls | Continuous power supply |
| Hits per heat cycle | 1 (then recharge) | Unlimited |
| Bowl compatibility | Limited (needs efficient heat transfer) | Wide (continuous heat compensates distance) |
| Mobility | Flexible around the house | Tied to cable/outlet |
| Complexity | Simple entry | More tuning options |
Stainless steel version: worth the upgrade?
Crossing Tech also offers the WOHW in stainless steel. The heavier material slightly increases the thermal mass of the injector head. In practice, that should be noticeable – a bit more stored heat per cycle. But it doesn’t change the fundamental concept: it stays a One Hit Wonder, not a Two Hit Wonder.

Verdict: compact entry with a clear trade-off
For a purchase decision, the specific WOHW version, the package contents, the compatible bowl connections, and a suitable water filter are the key factors. Wireless here means a detachable heating head during the draw; the entire system continues to operate on mains power. The head returns to the dock for reheating. A guaranteed number of draws per heating cycle or a specific cannabinoid yield was not measured for this article. Compare current offers and the manufacturer’s manual for your chosen variant.
Price History
What does “wireless” mean on the CrossingTech WOHW V2?
“Wireless” refers only to the detachable injector head: for a draw, you lift it off the docking station without any cable. The PID controller and heating coil remain connected to mains power; the WOHW V2 is not a battery vaporizer. Crossing explicitly points this out in the official product description.
Does the WOHW V2 require a water filter?
Yes. The complete set includes the injector head, PID controller, docking station, and a matrix bowl with 14.4 mm and 18.8 mm glass joints, but no water filter. You therefore need a matching bubbler or bong with a female joint; the manufacturer also states this.
