Description
This 510 Battery from Fernway, sold by the brand as the Stylus, is a pen-style power source made to pair with its 510-thread cartridges and compatible with standard 510 carts from other brands. Retail listings for the Stylus describe four preset heat levels (2.6V, 3.0V, 3.4V and 3.8V), USB-C charging with pass-through so you can keep using it while plugged in, a two-click preheat for cold weather or clogs, and a click-to-check power gauge. Fernway recommends starting at the lower settings for the best flavor. At Ava it is the natural add-on for any of the Fernway cartridges on the shelf.
- Type: 510-thread pen battery
- Heat settings: 4 presets: 2.6V, 3.0V, 3.4V, 3.8V
- Charging: USB-C with pass-through charging
- Preheat: 2 clicks (for cold weather or clogs)

Wipe the threads with a dry cloth now and then, never overtighten the cartridge, and store the battery away from heat and moisture.
FAQ
Questions About This Product
Per the Stylus listing: five clicks turns it on or off, three clicks cycles the four color-coded heat presets, and two clicks runs a preheat.
Yes. It is a standard 510-thread battery, so most cartridges sold in New York dispensaries fit.
Four clicks shows the power gauge: green is full, amber is medium and red means it is time to plug in by USB-C.
