The Pulsar RoK Electric Dab Rig represents a thoughtful evolution in portable electronic dabbing. Combining the smooth water filtration of traditional glass rigs with the convenience of electronic temperature control, the RoK aims to deliver a premium dabbing experience without the hassle of torches, timers, or guesswork.
Standing at a compact 6.75 inches tall, the RoK bridges the gap between desktop e-rigs and ultra-portable wax pens. It's designed for users who want better vapor quality than a pen can provide but don't need (or want) a full-sized rig dominating their space. The inclusion of both concentrate and dry herb functionality, along with two different atomizer materials, makes this a versatile option for users with varied preferences.
Pulsar has established themselves as innovators in the vaporizer space, and the RoK showcases their commitment to creating functional, user-friendly devices that don't sacrifice performance for convenience. Whether you're a seasoned dabber looking for an electronic alternative or a newcomer seeking an approachable entry point, the RoK merits serious consideration.
Design & Build Quality
The Pulsar RoK immediately impresses with its thoughtful integration of metal and glass components. The sturdy metal body houses the battery and electronics, while the borosilicate glass bubbler provides water filtration and cooling. This combination balances durability with functionality, creating a device that feels substantial without being unwieldy.
Construction and Materials
The base unit features an all-metal construction with a matte finish that resists fingerprints and provides secure grip. The engineering here prioritizes practicality: the atomizer chamber is easily accessible, the water reservoir is simple to fill, and all removable components fit together with satisfying precision.
The borosilicate glass bubbler is the centerpiece of the RoK's design. This isn't thin, fragile glass but rather the same durable material used in quality bongs and scientific glassware. The integrated disc percolator creates efficient diffusion, breaking vapor into fine bubbles for maximum water contact and cooling.
Atomizer System
One of the RoK's standout features is its dual atomizer system. The kit includes both a coilless quartz V2 atomizer and a coilless ceramic atomizer, each offering distinct characteristics:
Quartz Atomizer: Heats quickly and provides crisp, clean flavor with minimal interference. Ideal for users who prioritize terpene expression and immediate heat-up times. The V2 designation indicates Pulsar's updated design with improved heat distribution.
Ceramic Atomizer: Offers slightly slower heat-up but maintains temperature more consistently throughout the session. Many users find ceramic provides denser vapor production, making it preferable for those prioritizing cloud output over pure flavor.
Both atomizers are coilless, meaning concentrates make direct contact with the heated surface rather than a wrapped coil. This design reduces hot spots, prevents burning, and generally produces cleaner-tasting vapor.
Airpath Design
The RoK features isolated, expanded airpaths that keep vapor separate from the internal electronics. This isolation serves two purposes: it prevents any electronic odors from contaminating vapor flavor, and it protects the battery and circuitry from residue buildup. The expanded airpath also reduces draw resistance, allowing comfortable inhalation without excessive effort.
Size and Portability
At 6.75 inches tall, the RoK is notably compact for a water-filtered e-rig. It's not pocket-sized (the glass bubbler prevents that), but it transports reasonably well in a padded case or bag. The footprint is small enough for desktop use without dominating the space, and the stable base prevents tipping during normal use.
Available Editions
The RoK comes in several limited edition variants, including the Luna (glow-in-the-dark green), Full Spectrum Rainbow, and various collaboration designs. These editions typically feature colored glass components and special finishes while maintaining identical functionality to the standard version.
Features
Three Temperature Settings
The RoK offers three voltage/temperature settings to accommodate different concentrate types and personal preferences:
| Setting | Voltage | Approximate Temperature | Best For |
|---|---|---|---|
| Low | 3.4V | ~680°F | Flavor-focused sessions, terpene preservation |
| Medium | 3.6V | ~750°F | Balanced vapor and flavor |
| High | 3.8V | ~850°F | Maximum vapor production, thick concentrates |
Cycling through settings is simple: press the power button three times to advance to the next temperature level. LED indicators show which setting is currently active, making it easy to identify your selection at a glance.
RoK Mode (30-Second Extended Draw)
Perhaps the most distinctive feature is RoK Mode, which provides 30 seconds of continuous heating for extended draw sessions. Standard operation limits draws to approximately 10 seconds for safety, but RoK Mode overrides this limit for situations requiring longer heat application.
This feature proves particularly valuable for:
- Group sessions: Pass the rig without interruption
- Low-temperature dabbing: Allow concentrates to fully vaporize at lower temps
- Larger loads: Ensure complete vaporization of bigger dabs
- Dry herb use: Give herbs adequate time to release vapor
Activating RoK Mode typically requires a specific button sequence (detailed in the manual), preventing accidental activation during normal use.
Water Filtration System
The integrated disc percolator creates hundreds of tiny bubbles as vapor passes through water, dramatically cooling and smoothing each hit. This isn't just about temperature reduction; water filtration also helps trap larger particles, delivering cleaner vapor to your lungs.
The water chamber is sized appropriately for the device, providing meaningful filtration without requiring excessive water that could splash into the airpath. Fill lines indicate optimal water levels, and the clear glass makes monitoring easy.
Dual-Use Capability
While primarily designed for concentrates, the RoK can also vaporize dry herb using the included herb carb cap and appropriate technique. This versatility appeals to users who enjoy both formats without wanting multiple dedicated devices. However, concentrate use remains the RoK's primary strength; herb functionality is more of a bonus than a primary feature.

This accessory bundle demonstrates Pulsar's understanding that e-rigs require maintenance. Including cleaning supplies in the box encourages proper care from day one.
Performance
Vapor Quality
The RoK delivers impressive vapor quality across all temperature settings. The combination of coilless atomizers and water filtration produces smooth, flavorful hits that rival or exceed many competitors at this price point.
At the lowest temperature setting (3.4V), flavor preservation is excellent. Terpene-rich concentrates express their full profile with minimal harshness. The quartz atomizer particularly shines here, delivering clean, uncontaminated flavor that lets quality concentrates speak for themselves.
Moving to medium settings provides the balanced experience most users prefer for daily sessions. Vapor production increases notably while maintaining good flavor, striking a sweet spot for varied concentrate types and viscosities.
High temperature settings maximize vapor output for those prioritizing density over flavor nuance. Thicker, more stubborn concentrates benefit from this additional heat, vaporizing completely rather than pooling in the atomizer.
Heat-Up Time
The RoK heats to operational temperature in approximately 30 seconds, which is reasonable for an e-rig but slower than some pen-style devices. This heat-up time supports flavor preservation; rushing to temperature often produces harsher, less flavorful vapor.
The ceramic atomizer takes slightly longer to reach temperature than quartz but maintains heat more consistently once there. Users who prefer ceramic often pre-heat briefly before loading concentrates.
Battery Life
The 1600mAh battery provides sufficient power for moderate sessions, though heavy users may find themselves reaching for the charger sooner than expected. Expect approximately 25-35 sessions per charge depending on temperature settings, draw length, and ambient conditions.
The RoK cannot be used while charging (no pass-through), so plan accordingly for longer sessions. Charging via micro-USB takes approximately 2-3 hours from empty to full.
Water Filtration Effectiveness
The disc percolator performs admirably, creating smooth diffusion without excessive drag. Hits are noticeably cooler and smoother compared to dry e-rigs or wax pens, particularly at higher temperature settings where harsh vapor would otherwise dominate.
Some users prefer minimal water for less filtration (preserving more flavor), while others maximize water level for maximum cooling. The RoK accommodates both preferences within its design constraints.
Maintenance Considerations
Like all e-rigs, the RoK requires regular cleaning to maintain performance. Fortunately, the design facilitates this: atomizers remove easily for iso baths, the glass bubbler separates for thorough cleaning, and the included alcohol swabs handle quick touch-ups between deeper cleanings.
Residue buildup affects all aspects of performance (flavor, airflow, even heating efficiency), so establishing a regular cleaning routine is essential. Weekly deep cleaning with daily quick maintenance keeps the RoK performing optimally.
Who Is This For?
The Pulsar RoK appeals to several distinct user profiles:
Torch-Free Dabbers: If you've been dabbing with a torch and traditional rig, the RoK offers electronic convenience without sacrificing vapor quality. Water filtration provides the smooth experience you're accustomed to while eliminating butane, timing guesswork, and the hazards of open flame.
Upgrade Seekers: Users currently using wax pens who want better vapor quality will find the RoK a meaningful step up. Water filtration transforms the experience, delivering smoothness that compact devices simply cannot match.
Versatile Users: Those who enjoy both concentrates and occasional dry herb benefit from the RoK's dual-use capability. While not the best herb vaporizer, it provides serviceable functionality without requiring a second device.
Space-Conscious Consumers: The compact 6.75-inch height suits users without room for full-sized desktop rigs. The RoK delivers desktop-quality vapor in a footprint that works in smaller spaces or for those who prefer keeping equipment discreet.
Social Consumers: The 30-second RoK Mode caters specifically to group sessions, allowing shared experiences without constant button pressing or waiting for reheats.
The Bottom Line
The Pulsar RoK Electric Dab Rig successfully merges electronic convenience with the vapor quality advantages of water filtration. It's a thoughtfully designed device that addresses real user needs: smooth, flavorful vapor; adjustable temperature control; and versatile functionality across multiple material types.
The inclusion of both quartz and ceramic atomizers lets users customize their experience, while the comprehensive accessory kit demonstrates Pulsar's understanding that e-rigs require maintenance to perform their best. The 30-second RoK Mode adds unique functionality that distinguishes this device from competitors.
Areas for improvement exist: micro-USB charging feels dated in an era of USB-C ubiquity, and the glass components demand careful handling that some users may find anxiety-inducing. Battery life, while adequate, may frustrate heavy users who prefer extended sessions.
Despite these minor critiques, the RoK represents strong value at its price point. It outperforms many similarly-priced e-rigs in vapor quality while matching or exceeding them in build quality and features.
