Visibility Notes

The display is optimized for indoor use. Direct sunlight may make it difficult to read. Cup your hand around the display if viewing outdoors in bright conditions.

Dual Mesh Coil Technology

The Pulse X 25K uses two mesh coil elements firing simultaneously:

How Dual Mesh Works

  • Two heating elements - Double the surface area of single-coil designs
  • Mesh construction - Even heat distribution across the coil surface
  • Simultaneous firing - Both coils activate together for enhanced vapor
  • VPU monitoring - Active adjustment for consistent performance

VPU Technology Explained

The Vaporization Processing Unit (VPU) is Geek Bar's intelligent coil management system:

  1. Monitors coil condition - Tracks resistance and performance in real-time
  2. Adjusts power delivery - Compensates for coil aging and e-liquid depletion
  3. Maintains consistency - Helps flavor quality remain stable throughout device life
  4. Prevents dry hits - Reduces power if wicking issues are detected

The result is more consistent flavor from first puff to last compared to basic disposables that degrade as they empty.

AI-Powered Airflow System

How AI Airflow Works

Sensors detect your draw strength and automatically adjust airflow:

  • Light draws - Airflow tightens for MTL (mouth-to-lung) style
  • Strong draws - Airflow opens for DTL (direct-to-lung) hits
  • Variable draws - System adapts in real-time to your style

Manual Airflow Override

The side-mounted slider allows manual control:

  1. Locate the slider on the side of the device
  2. Slide toward mouthpiece for more airflow (looser draw)
  3. Slide toward base for less airflow (tighter draw)

Manual settings work alongside AI adjustment. Set your baseline preference and let AI fine-tune from there.

Vaping StyleSlider PositionAI Behavior

Maintenance and Care

Daily Care

  • Wipe the mouthpiece with a clean, dry cloth
  • Check display for battery and puff count status
  • Store upright when possible to maintain wicking

Storage Recommendations

  • Temperature - Store at room temperature (59-86°F / 15-30°C)
  • Avoid extremes - Don't leave in hot cars or freezing conditions
  • Keep dry - Protect from water and humidity
  • Away from sunlight - UV exposure degrades e-liquid quality

What to Avoid

  • Don't submerge in water - The device is not waterproof
  • Don't attempt to refill - The sealed design prevents safe refilling
  • Don't disassemble - No user-serviceable parts inside
  • Don't expose to extreme heat - May damage battery or cause leaking
  • Don't use damaged devices - Cracks, dents, or water damage warrant replacement

Troubleshooting

Q:Geek Bar Pulse X not charging

A:First, try a different USB-C cable since not all cables support adequate power delivery. Ensure you're using a 5V power source (phone chargers work best). Clean the charging port with a dry cotton swab to remove lint or debris. Check that the cable is fully inserted; the port is recessed and requires firm connection. If the display doesn't show charging animation, try a different USB port or wall adapter. Avoid using laptop USB ports which may not provide sufficient current.

Q:Geek Bar Pulse X blinking but not hitting

A:Blinking typically indicates low battery or a protection activation. If the display shows low battery, charge the device immediately. If blinking occurs during a long draw, this is the 8-10 second puff protection. Release and wait before taking another puff. Rapid blinking without display information may indicate the device has reached end of life or has a sensor issue. Try gentle draws to test activation.

Q:Geek Bar Pulse X burnt taste

A:A burnt taste means the coil is dry or damaged. With 18mL of e-liquid, this shouldn't happen early in the device's life. First, wait 30 seconds between puffs to allow wicking. If burnt taste persists on a new device, it may be defective. Contact the retailer. On an older device with low puff count remaining, the e-liquid is likely depleted. The device should be replaced.

Q:Geek Bar Pulse X screen not working

A:The display should illuminate when you draw or when charging. If the screen stays dark during use but the device produces vapor, the display may have failed while the vape function remains operational. If both the screen and vapor stop working, the battery is likely depleted. Charge the device. A partially working display (flickering, missing segments) indicates display damage; the device will still function but display accuracy may be compromised.

Q:Geek Bar Pulse X weak vapor or no throat hit

A:First, check you're in the correct mode. Regular mode produces moderate vapor while Pulse mode delivers stronger output. Triple-click to switch modes. Verify the airflow slider isn't fully closed. If the device is new and vapor seems weak, give it 10-15 puffs to fully prime the coils. For weak throat hit specifically, ensure you're using the 5% nicotine version (0% versions have no throat hit). Low battery can also reduce power output, so charge the device.

Q:Geek Bar Pulse X auto-firing or firing on its own

A:Auto-firing is a serious issue. Immediately set the device down on a non-flammable surface. E-liquid may have entered the draw sensor, causing false activation. Allow the device to rest for 15-30 minutes. If auto-firing continues, the device is malfunctioning and should not be used. Do not attempt to charge a device that auto-fires. Contact the retailer for replacement.

The 3D display shows: remaining puff count (numerical countdown), battery percentage (0-100%), current mode indicator (Regular or Pulse), and animated graphics during use and charging. Low battery warnings appear when charge drops below 20%. The display illuminates during draws and charging, then dims to conserve power.

How long does a Geek Bar Pulse X 25K last?

In Regular mode, the device provides up to 25,000 puffs. In Pulse mode, capacity is approximately 15,000 puffs due to higher power output. For average users taking 300-500 puffs daily, a single device lasts 2-4 weeks. Heavy users may deplete it faster, especially in Pulse mode.

Why is my Geek Bar Pulse X blinking?

Blinking indicates: low battery (charge needed), puff timeout protection (exceeded 8-10 second draw limit), or device malfunction. Check the display for specific information like battery percentage or error indicators. If blinking continues after charging and the display shows adequate battery, the device may be malfunctioning.

Can I refill my Geek Bar Pulse X 25K?

No, the Geek Bar Pulse X 25K is not designed to be refilled. The sealed construction prevents access to the e-liquid reservoir. Attempting to refill may damage the device, cause leaking, or create safety hazards. The device is intended for single use until the e-liquid or battery is depleted.

What is VPU technology in the Geek Bar Pulse X?

VPU (Vaporization Processing Unit) is Geek Bar's coil monitoring technology. It actively adjusts power delivery to maintain consistent performance as the coil ages and e-liquid depletes. This helps maintain flavor quality throughout the device's lifespan, addressing the common issue of disposables tasting worse as they empty.
