110V air purifier with an adapter 100-240V

[chieanne]

I purchased an air purifier printed 110V. It has a power adapter of 100-240V. Can I use the air purifier with a power supply of 220-240V? Is the adapter also a converter or transformer? I’m really confused.

That usually indicates that the adapter has a switching power supply in it, and can indeed be powered with 240.

However an air purifier with a "wall wart" supplying it does not inspire confidence in me that it will be effective. How many watts is the adapter, and what is its output? That will probably be printed on the supply.

Thank you for your reply. It’s written as 100-240V. 50/60Hz. 0.8A
Output is 24V and 1A.
Does that mean I can use the air purifier anywhere in the world since the power adapter is 100-240V?

Yes.
