Training sessions can run long, but your vape doesn't have to. Disposables are meant for intermittent use, not chain-vaping. If you take several puffs in a row, the coil heats up, and you might get a burnt taste or reduced vapor.

Pace yourself. Take a few puffs for demonstration, then set the device down for a few minutes. This also gives your audience time to ask questions or take notes.

If you're doing multiple sessions back-to-back, rotate between two devices. That way, each one gets a rest period, and you always have a fresh unit ready.

Keep an eye on the e-liquid level if your device has a window. When it's low, vapor production drops, and the flavor gets weaker. That's your cue to switch to a backup.
