Here’s my experience, with AirPods w/ wireless case: they charge on my Nomad base station w/ Apple Watch dock, my wife’s Mophie wireless pad but not on my Taotronics desk light w/ wireless charger. I have heard others here having hit or miss experiences on various chargers.
My life hack is I use an Apple iPhone dock to charge them most of the time because it’s far easier than trying to find the sweet spot on wireless chargers.
