It’s just a plug-in dock. There are a bunch of those available. I pulled that particular example from the forum in the following thread because it showed SmartTiles a small device, but it looks like that specific model is no longer available.
Amazon usually calls these a “mini wall plug in dock charger”

Obviously you have to match the plug to your phone model.
Thingcharger is a new one with changeable tips. I don’t know how sturdy it is though, there are a lot of reviews about the phone getting knocked off of it. So you might need to add something additional to secure it. thing charger is different from the other chargers because The other ones have a dock that angles the device and thing charger just holds it straight vertically.
