Smyle Labs

Variable voltage 510 thread batteries built into everyday objects: a working pen, a car key fob, a permanent marker, an inhaler, a chapstick tube, a lit hilt and a raygun. Every one takes a standard 510 threaded cartridge, and most conceal it fully inside the housing.

Most of them do. Capacity is the limit rather than the design: the Chapstick, Car Key, Pursejamin and Wandjamin take up to 1G internally, the Saber up to 2G, and the Permanent Marker up to 4G including extra wide tanks. Larger cartridges sit on top and remain visible.

Penjamin is the naming family Smyle uses across several of its concealed batteries, starting with the Cart Pen that writes with real ink. The Saber and the Raygun carry the same name. Customers search for it by that word, so it is worth on the shelf tag rather than the brand name alone.

The Permanent Marker, at up to 4G, which is enough for the extra wide tanks that will not fit any other concealed housing. That makes it the one to point a customer toward when they have already tried a concealed battery and found their cartridge would not go in.

Yes. The Inhaler ships with cloud filters that trap exhaled vapor to reduce visible clouds and odor, and they are consumable. Replacements come as a three pack, which makes them a genuine repeat line rather than a one off accessory sitting next to the units.

Most run three or four fixed steps between roughly 2.2V and 3.7V with a preheat function, which covers the range oil cartridges need without giving a customer enough rope to burn a coil. The Mini Plug is the exception, stepping from 1.5V to 4.2V on plus and minus buttons.

Yes. The Mini Plug ships twenty to a box with a cardboard pop up display included, so it goes on the counter without any merchandising work. Each box carries seven colors, including gold and opal as the rarer finishes, so one order fills a full facing.

Yes, all of them, which means universal fitment with standard oil cartridges. Several units also ship with sized adapters so wider or narrower cartridges seat properly inside the housing. That universality is what lets a shop sell them alongside any cartridge program.

The Mini Plug 20pk, because it is display ready and the per unit cost is the lowest in the brand. Add a few Penjamin Cart Pens and one attention piece such as the Raygun or the Saber, which do most of their work by getting picked up.

The newer units do, including the Inhaler, the Car Key, the Saber and the Pursejamin, and the Mini Plug carries a USB-C cable inside its own body. A few older designs still ship with a micro USB cable, so check the included contents before promising a customer one cable fits everything.
