How to fill an empty disposable vape

Before you start

Identify the fill port. On most empty all-in-one disposables it sits under the mouthpiece or on the base; some use a silicone plug. Check the model's fill point before you begin.

Step by step

1. Warm the oil until it flows freely (around 40 to 60 C for distillate).
2. Open the port and fill slowly down the inner wall, avoiding the central airpath, to the model's fill line.
3. Prime the coil. Let the device stand upright so the coil saturates. With a preheat model, a short preheat cycle helps the first draws.
4. Reseal the plug or mouthpiece firmly.
5. Charge. These devices ship at a low state of charge for transport; top up over USB-C so the first customer's device works to the last fill.
6. Test a unit from the batch.

Why disposables differ from carts

• The battery is sealed in, so charging before sale matters.
• Postless and ceramic builds handle thick oil better; see rosin hardware.
• Variable-voltage and display models let you tune the draw.
