Which is better for a large open-plan room?

The JCLOUD Pro-300, which is rated to 2000 sq ft against the CHAOFLIGHT's 1500 sq ft. For a room under 1500 sq ft the CHAOFLIGHT is enough.

Is the JCLOUD worth the extra money?

Only if you need the larger coverage and the 300 ml tank. At $59.99 the CHAOFLIGHT does the same cold-air waterless job for a smaller room.

Do either of these need water?

No. Both use waterless cold-air diffusion and take diffuser oil directly, so there is no water tank to fill or clean.

Which needs refilling less often?

The JCLOUD, which states a 300 ml oil capacity. CHAOFLIGHT does not state its oil capacity, so refill frequency depends on your run schedule.

Can I control them from my phone?

Both have app control. The CHAOFLIGHT connects over Bluetooth and ships with a default app password of 1234, which you should change.

Which is easier to place?

The JCLOUD is freestanding. The CHAOFLIGHT uses an adhesive mounting plate and two screws, so it needs a wall or flat surface.
