- How long does one fill last?
- The 120 ml tank runs about 4 hours on a full fill. That suits a night or a work session, but not all-day use without refilling.

- Yes. Auto shut-off cuts the unit when the water level gets too low, so it can run unattended.

- Yes, it has a timer function. Check the listing for the exact interval options before buying.
- Is it battery powered?
