Looks like these piezo chips are used for cordless stove fans. Just enough to run low power fan.

I have one - they're more a cool decoration than a fan. If you shape the fan blades to actually move air, the motor slows down to nearly stopped under the load. That's why when you buy them in the shop the fan blades are usually perfectly flat so they don't blow any air at all, but look cool on top of your stove.

Kinda thought they look too good to be true. Market is filled with them and I saw one referred in a sailing channel.

We’ve got mains powered one in our current place and it makes a big difference.
