XPERIA XA1 wireless charging : please HELP with this

[Stefinka]

Hello there, 

I am trying to recharge my #Xperia XA1 via wireless.

How does it work? 

I have activated the NCF option on my smartphone and then put it on the base for wireless charging, but it does not work.

Any other step I should do?

PS:

I am trying to recharge with a Yootech Wireless charger, that should be suitable to #Xperia XA1 

Thanks and kind regards

S.
