Bigger Wireless Dock Station for E-Nail Coils

Three main differences. First, coil clearance: the Crossing dock is built specifically for the 25mm barrel coil with tight tolerances. The Bigger Dock fits coils up to 30mm diameter and 40mm tall, including axial, deep axial, and 30mm bangers. Second, the M5 threaded holes: only the Bigger Dock has these, which is what enables multi-coil post mounts. The Crossing dock has no expansion capability. Third, quality control: the Crossing dock has better cosmetic finish and tighter manufacturing tolerances. The Bigger Dock ships with minor blemishes and is priced lower as a result.

If you are running a standard 25mm barrel coil and want the cleanest daily-driver dock, buy the Crossing. If you need to fit a bigger coil or you want to build toward a multi-coil workstation, buy this one.

Yes. Unlike the Crossing Wireless Dock, which is barrel coil only, the Bigger Dock accepts 25mm axial coils, 25mm barrel coils, and 25mm deep axial coils. This is important if you are using the 10-wrap deep axial coil, which does not fit the Crossing dock at all. If your build uses an axial coil and you need a dock, this is your primary option in the lineup alongside the Simple Machined Aluminum Stand and the Coil Stand and Clamp.

The dock has two M5-threaded holes in the body. Standard M5 mounting posts thread directly into these holes. Each post can hold a secondary coil holder or clamp. One coil clamps inside the main guard in the center of the dock, and one coil can be mounted on each post to either side. That gives you three coil positions off a single dock surface.

M5 hardware is standard metric sizing and widely available online. The posts are not included with the dock. You need a multi-channel or dual PID to run more than one coil independently. The Dual PID and Dual Coil SS WOHW bundle uses this configuration with two coils and the 25mm auto spinner kit as part of a single station. Hit Discord if you want specifics on the post hardware we have tested and found to work well.

This is the heat soak issue. The dock body absorbs radiant heat from the coil and the PID sensor reads this as higher than the actual coil temperature, meaning your real coil temperature is lower than what the display shows. The fix is straightforward: increase your set point in 10F increments until you get back to the vapor density you are used to. Most users land 10 to 30F higher on this dock than they would on a standard dock or bare coil setup.

This is not a defect and it is not specific to this dock. Any dock that thermally couples with the coil will show the same behavior. The Crossing dock does it too, just slightly less because the tolerances are tighter and the thermal contact is more predictable.

Yes, the Bigger Wireless Dock is standard equipment in the Dual PID and Dual Coil SS WOHW bundle. The bundle pairs two SS WOHW heaters with two independently controlled coils, a dual-channel PID, and the 25mm auto spinner kit for concentrate sessions. The M5 threaded holes in this dock are what make the dual-coil post mount possible, which is why this dock was selected for that bundle over the Crossing dock.

If you are building toward a two-heater station and want everything spec’d and ready to go in one order, the Build-Your-Own listing is where you configure it. You can also reach out via Discord or the contact page if you want a hand configuring the dual-coil build before ordering.

Yes, with the caveat that the clearance is tight. A 30mm coil fits inside the dock with roughly 1mm of clearance to the guard walls at the closest points. It will clamp and hold, but the dock body heats up more than it would with a 25mm coil because of increased radiant heat from the larger coil surface area. Expect more temperature variance between the PID reading and actual coil temperature and plan to bump your set point accordingly.

For slurpers that use oversized coils, this dock was designed with that use case in mind and is explicitly the better choice over the Crossing dock for that application. The Crossing dock should not be used with 30mm coils at all.
