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)
- Compatibility: Fernway and other standard 510 cartridges
Wipe the threads with a dry cloth now and then, never overtighten the cartridge, and store the battery away from heat and moisture.
The brand
Fernway
Fernway is an independent vape brand, in its own words the number one independent cannabis vape in New York, Massachusetts and New Jersey. The Traveler PRO is its own all-in-one design, sold in 1g and 2g, and the LIVE line adds live terpenes and minor cannabinoids. Ava’s Fernway shelf is the deepest single-brand vape selection in the store, with 510 cartridges and the Stylus battery alongside the Travelers.
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.
