iPhone 11 Pro Max Wireless Charging w/OtterBox Defender

[LelandT50]

So just got my new iPhone 11 Pro Max. Put it inside an OtterBox defender case. Previously had an iPhone X in an OtterBox defender, and charged it with a Samsung Fast Charge EP-PG950 wireless charger. The 11 Pro Max won't take a charge inside the OtterBox. FWIW, I tried it without the case, and with half the case (just the hard plastic shell without the rubber) and the 11 took a charge no problem. Anyways, does anyone know of a wireless charger that will work with my setup (iPhone 11 Pro Max in an OtterBox defender)? Or of a wireless charger that's known to work with thicker cases? I know I could likely have success by switching to a slimmer case but the defender has saved my phone so many times I'd rather just find a better wireless charger. Thanks!
