Vertex 350mAh VV 510 Battery Charger Kit
A slim, button-fired 510 battery with three voltage settings and a preheat mode — everything a cartridge needs and nothing it doesn't. Ships as a complete blister kit with the USB charger included.
The Vertex has been a shop staple for years for one reason: it just works. At 350mAh in a pen barely thicker than a marker, it disappears in a pocket, and the three-position voltage control lets you dial in the draw instead of fighting your cartridge. Run it low for flavor, high when a cart starts pulling thin.
The preheat function is what separates this from a plain fixed-voltage pen. Two quick clicks gently warms the oil before you draw, which clears the clogs and weak first-hits that thicker distillates are famous for in cold weather.
Features:
- 350mAh built-in battery — slim pen profile, roughly 10mm diameter
- Three voltage settings with color indicator: Green 3.4V · Blue 3.7V · Red 4.0V
- Preheat mode (2 clicks) for thick oils and cold-weather starts
- Universal 510 threading — fits most standard oil cartridges
- Single-button operation: 5 clicks on/off, 3 clicks voltage, 2 clicks preheat
- Short-circuit and overcharge protection
- Includes 510-threaded USB charger — no proprietary cable to lose
- Discreet matte black finish

Frequently Asked Questions:
Does a cartridge come with this kit?
No. The kit includes the battery and USB charger only.
Will it fit my cartridge?
It fits standard 510-threaded cartridges. Carts with an unusually wide base may not sit perfectly flush against the battery, though they will still thread on and fire.
Which voltage should I use?
Start at 3.4V (green). Ceramic and higher-end cartridges generally perform better at 3.7V or above. If your draw tastes burnt, step down; if it tastes weak or thin, step up.
Can I use this with a sub-ohm tank?
No. At 350mAh and a 4.0V ceiling this is built for 510 cartridges and low-power atomizers, not sub-ohm tanks.
How do I know when it's charged?
The indicator on the USB charger changes color when charging completes. A full charge takes about an hour.
