Which wireless charger are you using?

I got the Samsung 2019 15w wireless charger, as part of my 150.00

I have this new version of the Samsung duo charger. It's compact and flat versus the previous model. The left side that charges the phone is suppose to have more power versus the previous version. The right side that charges my smartwatch can be a little finicky for having to place in exactly the right position where the circle is to get the red color light to come on for charging. There is a built in fan that I can hear very low if it's in a very quiet room. Overall, I like it. But this model doesn't have the diagonal tilt for the phone to sit upright, but it's noticeably more compact than the previous model.
 
I have a few around the house and at work

I bought the chotech 15W charger.
It doesn't work well with my thick case even though the previous charger does, and today it stopped working all together, it's just flashing.

I'm returning it.
