I've tried at least four different cases that aren't as heavy and thick as Otto Defender or Commuter. Charge 5-10 seconds and stop charging after half a minute, charge again for 5-10 seconds, etc. Only charge without a case. No charger was included, just a thin cable that would overheat. I connected a 65W USB-C1, C2 and USB-A charger with a thick cable. I'm sending them back. Bought two others with the same problem!
