Big fan of this Anker charger. Very slim, and the LED lights turn off after 5 seconds. $17. Supports up to 10W charging (if Apple ever enables that.)

Tylt vu is by far my favorite.

I also have ankers charger but it is single coil so it is finicky on placement. It charges as fast as whichever adapter is used. I also us a QC 3.0 charger on that

The anker is faster, both gave fairly low heat input, I have the anker on my desk and the tylt vu at work.
