Overview
The Cartisan Veil Bar Flow has a built-in fan that blows vapor at your face. Sounds weird, right? That's the whole point. The "Flow Mode" feature lets you set the device down and lean in for hands-free hits.

Flow Mode
Extensively tested
Most 510 batteries just tweak the same formula. The Flow actually tries something new. Whether you'll use that feature more than twice is another story.
Design & Build Quality
The Flow uses Cartisan's concealed cartridge setup. Your cart sits inside the device, hidden and protected.
Form Factor
It measures 3.9" x 1.6" x 0.8", which is pocket-friendly despite packing both a battery and a fan. The soft-touch finish feels nice and the grip is comfortable.
Concealed Cartridge System
Carts up to 2 grams (14x52mm) fit inside the chamber. Once inserted, you can't see the cartridge at all. The device just looks like a regular vape bar.
What you get from this design:
- Discretion: Nobody knows it's a 510 device
- Protection: Your cart won't get banged up
- Aesthetics: Clean look without a cart sticking out
LED Lighting
LEDs show your voltage setting and add some visual flair. Nice touch, but nothing groundbreaking.
The Flow Mode Experience
Flow Mode is why this battery exists. It's also the most divisive part.
How It Works
- Press both buttons at the same time
- The device fires your cart automatically
- A small fan blows vapor toward your face
- You inhale without touching the device
Set it on a table, activate Flow Mode, lean in. That's the idea.
Where It Works
Flow Mode makes sense in a few situations:
Social Sessions: Pass it around and let people lean in for hits. No sharing mouthpieces, no awkward hand-offs mid-draw.
Multitasking: Gaming, eating, working on something. Your hands stay free.
Accessibility: If holding a device to your mouth is difficult, this helps.
Showing Off: People always react when you show them a vape that blows smoke at you. It's a conversation piece.
Where It Doesn't
For everyday solo use? It's kind of pointless.
- Why press two buttons when auto-draw works fine?
- The fan makes noise (quiet, but still there)
- Having vapor blown at your face is just weird when you could inhale normally
- More moving parts means more things that can break
Most people will try Flow Mode a few times, demo it for friends, then just use it like a normal battery.
Voltage Settings
The Flow has 5 voltage options, which is solid:
| Color | Voltage | Best For |
|---|---|---|
| Yellow | 1.8V | Max flavor, thin oils |
| Purple | 2.4V | Flavor-focused |
| Green | 2.8V | Everyday use |
| Blue | 3.4V | More vapor |
| Red | 3.8V | Thick distillates, big clouds |
The 1.8V to 3.8V range handles pretty much any cart. That 1.8V setting is great for live resin and terpene-heavy carts that taste better at low temps.
Performance
As a Standard Battery
Forget the fan for a second. How does it work as a normal 510 battery? Pretty well, actually. Auto-draw is responsive, the voltage options give you real control, and 650mAh gets you through a full day without stress.
Vapor production across the range:
- 1.8V-2.4V: Smooth, flavorful hits
- 2.8V: Works for most carts
- 3.4V-3.8V: Bigger clouds, more intensity
Battery Life
650mAh is enough for all-day use. Here's what to expect:
- Light users: 2-3 days per charge
- Moderate users: Full day, easy
- Heavy users: All day, no problem
USB-C charging is quick.
User Feedback
What people are saying:
"Nice hits depending on how you set it."
General vibe: solid battery, fun feature, but you won't use Flow Mode every day.
Value Analysis
$28 is a bit steep for a concealed battery. Here's how it stacks up:
| 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 |
That $5 premium over the Neo is basically what you're paying for the fan. If Flow Mode sounds useful, cool. If not, save the money.
Who Should Buy This
Get the Flow if you:
- Vape with friends and want something fun to pass around
- Need hands-free hits for gaming or other activities
- Like weird gadgets even if you won't use them daily
- Want concealed design plus good voltage control
Skip it if you:
- Vape solo and won't bother with Flow Mode
- Hate paying for gimmicks you'll use twice
- Want simple and reliable without extra features
- Need total silence (the fan makes noise)
The Bottom Line
The Cartisan Veil Bar Flow does something different. The fan feature is fun to show off and works well for passing around in groups.
As a regular battery, it's solid. 5 voltages, concealed cart, all-day battery. Nothing to complain about there. You're really just deciding if Flow Mode is worth $5 extra.
Social vapers and gadget lovers will get a kick out of it. Everyone else should just grab the Veil Bar Neo and pocket the difference.
