Extensively tested
Innovation in the 510 battery space is rare - most improvements are incremental. The Flow Mode fan is genuinely different. Whether that difference is useful depends entirely on how you vape.
Design & Build Quality
The Veil Bar Flow follows Cartisan's concealed cartridge design language. Your cart sits inside the device body, hidden from view and protected from damage.
Form Factor
At 3.9" x 1.6" x 0.8", the Flow is compact enough for pocket carry while housing both the battery and fan mechanism. The soft-touch construction feels good in hand with an ergonomic grip.
Concealed Cartridge System
Cartridges up to 2 grams (14x52mm) fit inside the Flow's chamber. Once inserted, the cartridge is invisible - the device looks like a standard vape bar rather than a cart battery. This provides:
- Discretion: No visible cartridge identifying it as a 510 device
- Protection: Cartridge shielded from impacts and drops
- Aesthetics: Clean, unified appearance
LED Lighting
LED lights provide visual feedback for voltage settings and add ambient appeal. It's a nice touch that enhances the device's modern aesthetic.
The Flow Mode Experience
Flow Mode is the Flow's defining feature - and its most polarizing one.
How It Works
- Press both buttons simultaneously to activate Flow Mode
- The device fires your cartridge automatically
- A built-in fan blows the generated vapor toward you
- Inhale the vapor stream without holding the device to your mouth
The fan creates a gentle, directed airflow that carries vapor to your face. It's hands-free vaping - set the device down, activate Flow Mode, and lean in.
Where It Works
Flow Mode shines in specific scenarios:
Social Sessions: Pass the Flow around a circle and let each person lean in for their hit. No mouthpiece sharing, no hand-offs during active draws.
Multitasking: Keep your hands free for gaming, working, or eating while the Flow delivers vapor on demand.
Accessibility: Users with hand mobility issues can benefit from not needing to hold a device to their mouth.
Novelty: It's genuinely fun to show people a battery that blows vapor at you.
Where It Doesn't
For solo, everyday use, Flow Mode is more gimmick than feature:
- Adding a step (two-button press) when auto-draw works fine
- Fan noise, however quiet, adds an unnecessary sound
- Directing vapor at your face feels odd when you could just inhale
- Potential failure point in the fan mechanism
Most users will try Flow Mode a few times, show friends, then primarily use standard auto-draw operation.
Voltage Settings
Beyond Flow Mode, the Flow offers a competent five-setting voltage range:
| Color | Voltage | Best For |
|---|---|---|
| Yellow | 1.8V | Maximum flavor, thin oils |
| Purple | 2.4V | Flavor-focused vaping |
| Green | 2.8V | Balanced everyday use |
| Blue | 3.4V | Increased vapor production |
| Red | 3.8V | Thick distillates, big clouds |
This 1.8V-3.8V range covers virtually all cartridge types. The 1.8V floor is particularly useful for live resin and terpene-rich cartridges.
Performance
As a Standard Battery
Ignoring Flow Mode, the Veil Bar Flow performs well as a concealed 510 battery. Auto-draw activation is responsive, the five voltage settings provide real customization, and the 650mAh battery handles daily use comfortably.
Vapor production is consistent across the voltage range:
- Lower settings (1.8V-2.4V) deliver smooth, flavorful draws
- Mid-range (2.8V) suits most cartridges well
- Higher settings (3.4V-3.8V) produce denser clouds
Battery Life
The 650mAh capacity provides genuine all-day use:
- Light users: 2-3 days between charges
- Moderate users: Full day with room to spare
- Heavy users: Comfortable all-day use
USB-C charging replenishes the battery quickly.
User Feedback
Community reception is positive but qualified:
"Nice hits depending on how you set it."
The consensus: good battery, interesting feature, situational usefulness.
Value Analysis
At $28, the Flow costs more than most concealed batteries. Here's the comparison:
| Battery | Price | Concealment | Voltage Range | Unique Feature |
|---|---|---|---|---|
| Veil Bar Flow | $28 | Yes | 1.8-3.8V | Fan/Flow Mode |
| Veil Bar Neo | $23 | Yes | 1.8-3.8V | LCD display |
| Veil Bar Duo | $29 | Yes | 1.8-3.8V | Dual cartridge |
You're paying approximately $5 for the Flow Mode fan over comparable options. Worth it if you'll use it; not worth it if you won't.
Who Should Buy This
The Veil Bar Flow makes sense if you:
- Vape socially and want a novel sharing experience
- Value hands-free operation for multitasking
- Enjoy innovative features even if situational
- Want concealed cartridge design with solid voltage options
Look elsewhere if you:
- Primarily vape solo and won't use Flow Mode
- Want maximum value without paying for features you won't use
- Prefer simplicity over novelty
- Need complete silence during use
The Bottom Line
The Cartisan Veil Bar Flow is genuinely innovative in a category where innovation is rare. The Flow Mode fan creates a unique experience that's perfect for social sessions and genuinely fun to demonstrate.
As a standard battery, the Flow performs admirably with five voltage settings, concealed cartridge design, and all-day battery life. The question is whether you value the Flow Mode feature enough to pay the premium.
For social vapers and novelty seekers, the Flow delivers something no other battery offers. For everyone else, the Veil Bar Neo provides similar core functionality at a lower price.
Innovation has its place. The Flow Mode fan might be yours.
