Cartisan Button VV 900 Dual Charge USB-C 2G

The Cartisan Button VV 900’s groundbreaking dual charging feature is the first in the 510 battery market to accept BOTH USB-C AND Lightning cables, solving one of vaping’s most common frustrations: cable incompatibility. The battery includes both a USB-C charging cable and a Lightning cable in the package. To charge, simply connect whichever cable is convenient – if you’re in an environment with Apple chargers (friend’s house, car with iPhone cable, etc.), use the Lightning cable; if you’re around Android devices or modern electronics, use the USB-C cable. Both cables charge the 900mAh battery equally effectively, reaching full charge in approximately 90-120 minutes. The LED light turns red during charging and green when complete. This flexibility is invaluable for travelers, forgetful users, or anyone who struggles with carrying specific cables. Forgot your charging cable? Borrow any compatible cable from friends regardless of their phone brand. Lost your USB-C cable? Your iPhone cable works perfectly. This dual-charging innovation eliminates the single biggest complaint about 510 batteries: dead battery with wrong cable available. While most manufacturers force you into one cable standard, Cartisan recognized that users encounter both cable types daily and designed accordingly. The dual charging alone justifies choosing the Button VV 900 over single-cable competitors, providing genuine practical value beyond marketing gimmicks.

The Cartisan Button VV 900 Dual Charge USB-C 2G features an updated flat-top 510 threading specifically designed to accommodate the increasingly popular 2-gram cartridges that have recently flooded the market. Older 510 batteries have a raised, domed threaded connection that creates a gap beneath standard 1g cartridges, which looks fine, but this raised design prevents wider 2g cartridges from sitting properly because the cartridge base hits the raised dome before fully threading. The Button VV 900’s flat-top design solves this: the threading sits flush with the battery top, allowing 2g cartridges to thread completely without obstruction. However, this creates a new issue: standard 1g cartridges now have a visible threading gap between the cartridge base and flat battery top, looking less polished. Cartisan includes a domed threaded adapter that screws onto the flat-top threading, recreating the traditional raised connection point. When using 1g or smaller cartridges, screw the domed adapter onto the battery first, then screw your cartridge onto the adapter – this creates the smooth, seamless transition you’re used to. When using 2g cartridges, remove the domed adapter and screw the larger cartridge directly onto the flat-top threading. The included skirt adapter further smooths the visual transition between any cartridge and battery body regardless of diameter differences. This thoughtful design future-proofs your investment as 2g cartridges become more common while maintaining compatibility with existing cartridge collections.

The Cartisan Button VV 900’s preheat function is designed to prepare thick oil cartridges for smooth vaping by gently warming the concentrate without actually vaporizing it, preventing clogs and ensuring consistent hits. To activate preheat: with the battery powered on (5 clicks), quickly press the button twice within 1-2 seconds. The LED indicator will flash or display a specific pattern indicating preheat mode is active. The battery heats at low voltage (typically around 1.8V-2.0V, lower than any of the three vaping voltages) for approximately 8-10 seconds, warming the oil enough to liquify it without burning terpenes. After the preheat cycle completes automatically, the battery returns to your previously selected voltage setting, ready for normal vaping. Preheat is particularly valuable first thing in the morning when cartridges have been sitting overnight in cool temperatures, for distillate or rosin cartridges which have naturally thicker viscosity, after extended periods of non-use when oil has settled and thickened, or in cold weather when all oils become more viscous. Some users activate preheat before every session as preventative maintenance, while others reserve it for problematic thick cartridges. The preheat doesn’t consume significant battery since it’s low voltage and brief. This feature extends cartridge life by preventing the clogs that force many users to throw away cartridges before they’re truly empty, potentially saving more than the battery’s cost over time.

The Cartisan Button VV 900 provides three voltage levels, each color-coded for easy identification and optimized for different vaping preferences and cartridge types. Green (3.4V – Low): This lowest setting emphasizes maximum flavor and terpene preservation. Use green for premium live resin cartridges, high-terpene distillates, or any time taste is your top priority over cloud size. The cooler vapor is also gentler on the throat. Green is perfect for daytime use when you want effects without intense vapor. Blue (3.7V – Medium): The middle ground provides balanced performance suitable for most standard cartridges. Blue delivers good visible vapor while maintaining reasonable flavor, working well with typical dispensary carts. Most users find blue their default setting for everyday vaping. Red (4.0V – High): Maximum voltage produces the biggest clouds and most intense throat hit. Use red for very thick oils that need extra heat, when flavor is secondary to potency, or when you want maximum visible vapor. Red drains battery faster than lower settings. To change voltage, click the button 3 times quickly – the LED cycles through colors indicating your selection. The battery remembers your last setting even after powering off. Start at green for any new cartridge and increase only if vapor production seems insufficient. Many users keep different cartridges at different voltages based on oil type: live resin on green, distillate on blue, super-thick rosin on red. The simple color system makes voltage selection intuitive even for beginners.

Yes! The included skirt adapter is a clever accessory designed to create a seamless, professional appearance between any 510 cartridge and the Button VV 900 battery body, regardless of diameter mismatches. Many cartridges have different base diameters than the 14mm battery body – some cartridges are wider, some narrower. Without the skirt adapter, you see an unsightly gap or step where the cartridge meets the battery. The skirt adapter is a thin plastic or silicone sleeve that slides onto the cartridge’s base before screwing it onto the battery. Once installed, the adapter’s outer diameter matches the battery body diameter perfectly, creating a smooth, flush transition that looks polished and intentional rather than mismatched. This aesthetic detail matters more to some users than others, but most appreciate how it makes their setup look more expensive and professional. The skirt works with the vast majority of standard 510 cartridges – both 1g with the domed threaded adapter installed, and 2g on the flat-top threading. Some extremely narrow or unusually wide specialty cartridges might not fit the skirt perfectly, but these represent maybe 5% of the market. The skirt doesn’t affect performance, voltage, airflow, or battery life – it’s purely cosmetic but highly effective. Many users skip it for convenience, while aesthetics-focused vapers always use it. Having the option included free rather than sold separately demonstrates Cartisan’s attention to user experience details that competitors overlook.

The Cartisan Button VV 900 Dual Charge USB-C 2G represents exceptional value in the $15-25 price range, delivering features typically found only on more expensive 510 batteries. The value proposition breaks down as follows: First, the dual charging capability alone (USB-C AND Lightning) saves frustration and potentially money spent replacing incompatible cables – this innovation is genuinely useful, not a gimmick. Second, the 2g cartridge compatibility future-proofs your investment as the market shifts toward larger cartridges. Third, the 900mAh battery capacity matches or exceeds batteries costing twice as much. Fourth, three voltage settings provide meaningful customization without overwhelming complexity. Fifth, the preheat function prevents cartridge waste, potentially saving money on premature replacements. Sixth, the included accessories (both charging cables, domed adapter, skirt adapter) eliminate additional purchases. Seventh, the durable aluminum construction and simple button operation mean fewer replacements over time. Where it compromises for affordability: no digital display, no auto-draw option, and slightly larger form factor than ultra-compact premium batteries. However, for users who want solid voltage control, reliable performance, universal compatibility, and unique dual charging – without spending $40-60 on high-end options – the Button VV 900 delivers outstanding value. It’s particularly smart as a backup battery, travel device, or first purchase for budget-conscious beginners exploring variable voltage 510 batteries. The quality-to-price ratio makes this Cartisan model one of the best-value 510 batteries available.
