Overview
The Pulsar 510 Hall Pass takes a unique approach to the 510 battery category: rather than competing on specs or features, it competes on stealth. Designed to look exactly like an ordinary highlighter marker, the Hall Pass provides genuine disguise for users who need discretion.
The execution is impressive. The plastic housing mimics standard highlighter construction, complete with the satisfying pop when removing the cap. The familiar form factor raises zero suspicion in office supplies, desk drawers, or pencil cases. Only the initiated would recognize this writing implement actually vaporizes cartridges.
But the Hall Pass isn't just a novelty disguise. Beneath the highlighter exterior lies a functional 510 battery with five voltage presets, both auto-draw and button activation, an 8-second preheat function, and USB-C charging. Pulsar has ensured the stealth comes with substance.
For users in professional environments, educational settings, or any situation where obvious vaporizers draw unwanted attention, the Hall Pass offers a practical solution. It's stealth vaping done right.
Design & Build Quality
The Hall Pass's design is its defining feature. Pulsar has created a convincing highlighter replica that could sit on any desk without raising eyebrows.
The Disguise
The plastic housing exactly mimics standard highlighter construction. The proportions, colors, and texture match what you'd find in any office supply store. Several highlighter-style color options ensure the device blends naturally into writing implement collections.
The cap removes with the same satisfying pop as a real marker. This tactile detail adds authenticity; the sound and feel are exactly what you'd expect from highlighter manipulation. Inside, instead of a felt tip, you'll find the 510 cartridge port.
The attention to detail extends throughout. Nothing about the exterior screams "vaporizer" to casual observation. In a cup of pens or a desk organizer, the Hall Pass disappears among legitimate office supplies.
Cartridge Concealment
With the cap in place, the Hall Pass conceals cartridges up to 2g in size. You inhale through the cap tip, drawing vapor through the concealed cartridge. This allows fully disguised operation where even the vaping motion resembles considering what to highlight.
For larger cartridges that don't fit with the cap, the device works capless like a standard 510 battery. You lose the full highlighter disguise but maintain the familiar form factor.
Controls and Indicators
The power button is located on the base of the device, positioned naturally as though it might be a cap for the highlighter body. LED indicators near the button show current voltage setting and battery status.
The button placement ensures natural grip during operation. Whether using auto-draw or button activation, the ergonomics feel comfortable despite the disguise constraints.
Build Quality
Construction quality is good for a novelty-focused device. The plastic housing is sturdy enough for daily carry, and the cap fits securely to prevent accidental removal. The 510 port provides reliable cartridge connection, and the USB-C charging port includes a silicone cover for protection.
The device won't win durability awards compared to metal-bodied alternatives, but it's sufficiently robust for its intended stealth-carry purpose.
Features
Five Voltage Presets
The Hall Pass offers five voltage settings, providing more range than many basic 510 batteries:
| Setting | Approximate Voltage | LED Indication | Best For |
|---|---|---|---|
| 1 | ~2.4V | Color 1 | Maximum flavor, light vapor |
| 2 | ~2.8V | Color 2 | Flavor focus |
| 3 | ~3.2V | Color 3 | Balanced performance |
| 4 | ~3.6V | Color 4 | Increased vapor |
| 5 | ~4.0V | Color 5 | Maximum output |
Cycle through settings by clicking the power button. LED indicators confirm the current selection, allowing adjustment without removing the cap or interrupting the disguise.
Dual Activation Modes
The Hall Pass supports both activation methods:
Auto-Draw: Simply inhale through the cap tip. The sensor detects airflow and activates heating automatically. This is the most discreet mode, as operation looks exactly like considering what to highlight while holding a marker to your face.
Button Activation: Press and hold the base button during inhalation. Useful when auto-draw sensitivity needs supplementation or when precise activation timing is preferred.
Both modes work simultaneously; use whichever suits the moment.
8-Second Preheat Function
The preheat function gently warms cartridges for 8 seconds at low power. This prevents the clogging common with thick oils and ensures consistent performance from the first draw.
Activate preheat by double-clicking the power button. The LED indicates preheat activation, and the device warms the cartridge without producing vapor. Useful for:
- New cartridges
- Thick distillate formulations
- Cold weather operation
- Cartridges that have been sitting unused
USB-C Charging
Modern USB-C charging provides fast, convenient power replenishment. The charging port includes a silicone cover that maintains the highlighter aesthetic when not charging and protects against debris.
The charger is not included in most packages, but any standard USB-C cable works. Charge time is approximately 60-90 minutes from depleted.
Cap-On Operation
The ability to operate with the cap in place (for cartridges up to 2g) enables fully disguised vaping. The cap's tip serves as the mouthpiece, with airflow channels directing vapor from the concealed cartridge.
This design detail transforms casual use into a convincing highlighter-holding gesture. Combined with auto-draw activation, operation appears completely innocent to observers.
Performance
Vapor Quality
Despite its novelty appearance, the Hall Pass delivers legitimate vapor quality. The five voltage options provide adequate range for optimization, and the firing system performs consistently.
At lower voltages (settings 1-2), flavor preservation is good. Quality cartridges express their terpene profiles without excessive harshness. The limited airflow through the cap tip actually helps concentrate flavor, similar to restricted airflow in some premium devices.
Higher voltages (settings 4-5) increase vapor production noticeably. Dense clouds are achievable, though the cap's airflow restriction means you won't match wide-open devices for raw volume. For discreet use, this limitation is actually beneficial; huge clouds defeat the stealth purpose.
Auto-Draw Sensitivity
The auto-draw sensor performs well, activating consistently with moderate draw strength. False triggers are rare during normal handling, and the sensor responds promptly to inhalation.
Through the cap, draw resistance is naturally higher, which actually improves auto-draw consistency. The restricted airflow creates clear activation differentiation from handling movement.
Battery Life
Battery capacity (estimated 400-500mAh based on form factor constraints) is modest but adequate for moderate daily use. Expect approximately:
- Light use (10-20 puffs daily): 2-3 days per charge
- Moderate use (20-40 puffs daily): 1-2 days per charge
- Heavy use (40+ puffs daily): Daily charging likely
The stealth use case typically involves lighter, more discreet consumption, which aligns well with the battery capacity. Heavy continuous use isn't the Hall Pass's intended scenario.
Real-World Stealth
The Hall Pass succeeds in its primary mission: genuine stealth. In office environments, educational settings, or any location where obvious vaporizers would draw attention, the disguise works.
Several aspects enhance the illusion:
- The familiar form factor triggers no suspicion
- Removing and replacing the cap looks natural
- Auto-draw operation mimics highlighter contemplation
- LED indicators are subtle enough to miss casually
- Overall construction matches highlighter expectations
Users report successfully using the Hall Pass in situations where standard vaporizers would be inappropriate or attention-grabbing. The disguise delivers on its promise.
Who Is This For?
The Pulsar 510 Hall Pass serves specific needs effectively:
Professional Environment Users: Office workers, professionals, and others in formal environments where vaporizer use would be frowned upon or prohibited will appreciate the complete disguise. The Hall Pass looks entirely at home among desk supplies.
Students: In educational settings where vaping devices face strict policies, the Hall Pass's highlighter appearance provides cover. It fits naturally in pencil cases, backpacks, and on desks.
Discretion Prioritizers: Anyone who values privacy about their vaping will find the Hall Pass useful. Even in accepting environments, some users prefer their choices remain private.
Stealth Enthusiasts: Users who appreciate clever product design and the "spy gadget" appeal will enjoy the Hall Pass's concept execution. The attention to detail in the disguise is genuinely impressive.
Situational Discretion Seekers: Those who sometimes need stealth but not always can use the Hall Pass as a situational device alongside more capable primary equipment.
The Bottom Line
The Pulsar 510 Hall Pass succeeds at its unique mission: providing genuinely discreet vaping in a convincing everyday object disguise. The highlighter form factor isn't just a gimmick; it's a thoughtfully executed stealth solution that actually works.
More impressive is that Pulsar didn't sacrifice functionality for novelty. Five voltage settings, dual activation modes, preheat function, and USB-C charging provide more capability than many basic 510 batteries. The Hall Pass is a legitimate vaporizer that happens to look like a highlighter, not a novelty item that barely functions.
Performance meets expectations for the form factor. Vapor quality is good, battery life is adequate for moderate use, and the auto-draw activation works reliably. Heavy users will find the capacity limiting, but the stealth use case generally involves lighter consumption anyway.
The disguise itself is the star feature. The familiar pop of the cap, the authentic proportions, the natural grip, the USB-C port hidden under a silicone cover - these details transform a 510 battery into office supply camouflage. For users who need this kind of discretion, no alternative comes close.
Should you buy the Hall Pass? If stealth is a priority, absolutely. The execution of the concept is excellent, and the underlying vaporizer functionality delivers. If discretion doesn't matter to you, better-performing standard options exist. But for the right user with the right need, the Pulsar 510 Hall Pass is a clever, practical solution to a real problem.
