Question about Xiaomi SmartMi 2S

Hello customer,
To answer your question as briefly as possible, I had to do a little searching and found out that the Xiaomi Mi Fan and Smartmi 2s each have a battery with 2800 mA, which seems a bit too low for a fan with a DC motor. I would recommend a mains powered fan.

On a personal note, I bought this model and am very pleased with it, it might be something for you. Brandson DC (Stand Fan, 30W)

The Smartmi 2s also has an app with which you can control the fan. I find it questionable that such apps for fans are offered at all, only that large well-known internet services also know that you own a fan and also know when you are at home and when you are not.

I didn't find out much about the C1 model, only that it was app controlled, mains or battery operated.

I hope I have answered your questions.

Greetings
Elmar
