A Geek Bar lasts as long as its e-liquid does. The battery recharges, so the number that matters is capacity in millilitres divided by how much you vape in a day. For most people that works out at one to five weeks, depending on the model.
Days of use by Geek Bar model
| Model | E-liquid | Battery | Puff rating (manufacturer) | Light use (0.5 mL/day) | Moderate (1 mL/day) | Heavy (2 mL/day) |
|---|---|---|---|---|---|---|
| Geek Bar Pulse X 25K | 18 mL | 820mAh | Regular Mode: 25K | Pulse Mode: 15K | 36 days | 18 days | 9 days |
| Geek Bar Pulse 15000 | 16 mL | 650mAh | 15000 | 32 days | 16 days | 8 days |
| Geek Bar CLR 50K | 17 mL | 900mAh | PULSE MODE: 25,000 Puffs | REG MODE: 50,000 | 34 days | 17 days | 8 days |
| Geek Bar 2GO 50K | 20 mL | not published | 50000 (50K) | 40 days | 20 days | 10 days |
| Geek Bar Burj 80K | 25 mL | 1500mAh | ECO: 80,000 | REG: 60,000 | PULSE: 40,000 | 50 days | 25 days | 12 days |
| Geek Bar Hookah X 25K | 18 mL | 820mAh | 25000 (Pulse Mode) | 15000 (DTL Mode) | 36 days | 18 days | 9 days |
The day counts are simple arithmetic: capacity divided by daily use. They are estimates, not manufacturer claims. Roughly 1 mL a day is typical for a moderate user of a 5% nicotine-salt device.
Why the puff count on the box is higher than what you get
Puff ratings are measured by a machine taking short puffs in the lowest power mode. Real puffs are longer, and pulse or boost mode uses e-liquid roughly twice as fast. That is why a device can be rated for tens of thousands of puffs and still last two or three weeks. Our article on what puff counts really mean goes through the numbers.
How to make a Geek Bar last longer
- Use regular mode. Pulse mode roughly halves the run time.
- Take shorter puffs and leave a few seconds between them so the coil does not overheat.
- Keep it charged. A nearly flat battery gives weak vapor, which leads to longer puffs.
- Store it upright and out of heat.
How do I know when it is finished?
Models with a screen show the e-liquid level. On any model, a burnt or dry taste that does not go away after charging means the e-liquid is gone. A device that dies well before the estimates above while still showing liquid may be faulty; see our warranty page.
