What it is

The Cartisan Pro Pen NEO 900 is a 510-threaded cartridge battery — the power source, not the cartridge. What separates it from the pen batteries sold at gas station counters is the full-color digital screen and genuine variable voltage.

Who it’s for

Anyone running 510 cartridges who is tired of guessing. If you’ve ever wondered whether your battery is nearly dead, or burnt a cartridge because a single fixed voltage ran too hot, this solves both problems for a modest price.

Why choose it

• You can see what it’s doing. The color screen reports voltage, heating time, battery indicator and state of charge.
• Five voltage settings: 2.1V / 2.5V / 2.9V / 3.3V / 3.7V, cycled with three clicks — dial the heat to the cartridge instead of forcing every oil through one setting.
• Preheat on two clicks, for thicker oil or cold weather.
• 900 mAh — a working day’s capacity for most users.
• USB-C charging, so it uses the same cable as the rest of your devices.
• Button activation — five clicks on/off, so it won’t fire in a pocket.

Compatibility

The NEO 900 uses standard 510 threading, which is compatible with a wide range of cartridges. Treat threading as a fit requirement rather than an assumption: matching a brand is not the same as matching a connector. If your cartridge is unusually wide or long, check it against the battery’s opening before ordering.

Choosing your color

Thirteen colorways: Black, Blaze, Blue, Charcoal, Green, Meadow, Ocean Depths, Purple, Rainbow, Zenith, Blush, Dawn and Synthwave. Select yours above — that selection is what ships.

Before you order

Start at a lower voltage with a new cartridge and step up only if the draw is weak; this is the single most effective way to avoid burning oil. An included cable is only assumed when it is specifically listed.
