An Off-Stamp lasts as long as its e-liquid: the battery recharges, so capacity in millilitres divided by daily use is the whole calculation. The 2 Off-Stamp kits in the Vaperan catalog that publish a capacity hold 17 to 18 mL, which at about 1 mL a day is 17 to 18 days. The table gives every model at light, moderate and heavy use; the sections after it cover charging and what to check when one stops hitting.
Days of use by Off-Stamp model
| Model | E-liquid | Battery | Puff rating (manufacturer) | Light (0.5 mL/day) | Moderate (1 mL/day) | Heavy (2 mL/day) |
|---|---|---|---|---|---|---|
| Off-Stamp X-Cube 25K | 18 mL | 1000mAh | 25,000 | 36 days | 18 days | 9 days |
| Off-Stamp X-Cube Crystal 25K | 17 mL | 1000mAh | 35,000 | 34 days | 17 days | 8 days |
The day counts are arithmetic, rounded down, not manufacturer claims. Puff ratings are machine maxima in the lowest power mode (puff counts explained). Replacement pod lines sold separately: Off-Stamp Classic Cube 25K, Off-Stamp Crystal Cube 25K, Off-Stamp Ice Cube 25K Pods and Off-Stamp Sweet Cube 25K Pods. Off-Stamp sells batteries with prefilled pods; the table uses the pod capacity of each kit.
How to charge an Off-Stamp
- Port: USB Type-C on every Off-Stamp model we stock that publishes it. A cable is usually not included (the product page’s in-the-box answer says what ships); any Type-C cable on a plain 5 V USB port works. Some fast chargers refuse to power a device that cannot negotiate; use a basic port.
- Time: Off-Stamp does not publish a charge time. The 1000 mAh cells in these models take roughly one to three hours from flat on a standard port.
- Indicator: 1 of the 2 models has a screen that shows the battery level; the others use the LED. A deeply flat cell can stay dark for the first minutes of charging.
- Rules: hard surface, not overnight, not in a hot car, never a damaged cable (battery safety). Not charging at all: the checks in order.
Off-Stamp not hitting: four checks
- Battery. No light, no vapor: charge it 20 minutes.
- E-liquid. Light on, no or weak vapor, or a burnt taste: it is empty. Screen models show the level; how to tell if a disposable is empty covers the rest.
- Airflow. On models with an adjustable airflow, fully closed can stop the draw sensor firing; open it a notch. Lint over the intake does the same.
- Mouthpiece. Condensation or a blocked mouthpiece: blow gently through it onto a tissue, wipe, try again.
A device that fails all four within the first month of delivery is a warranty case (warranty). The same checks in more detail, written for Geek Bar but valid for any draw-activated disposable: a Geek Bar that will not hit.
Questions
How long does an Off-Stamp vape last?
Capacity divided by use: 17 to 18 days at about 1 mL a day across the Off-Stamp models we stock that publish a capacity; half that for heavy use, double for light use. The table above has each model.
How do you charge an Off-Stamp?
With a USB Type-C cable on a plain USB port, roughly one to three hours from flat. The cable is not included.
How do I know when my Off-Stamp is done?
Screen models show the e-liquid level. On any model, a burnt or thin taste on a charged device means the liquid is gone.
Why is my Off-Stamp not hitting?
Flat battery, empty tank, closed or blocked airflow, or a blocked mouthpiece, in that order of likelihood.
What does the boost or turbo mode on an Off-Stamp do?
On the models that have one, it raises the power to the coil for denser vapor and stronger flavor, and uses e-liquid faster; that is why those models publish a lower puff rating for the boost mode. It does not change the nicotine strength.
How do I turn on an Off-Stamp?
You do not. Every Off-Stamp disposable we stock is draw-activated: it fires when you inhale. Models with a boost or turbo mode have a switch or button for the mode only; the device itself has no power button.
