To get the most out of your Qi2 Trio Wireless Charging Pad, we suggest using MagSafe or Qi2-compatible cases for your phone. It's best to steer clear of non-magnetic cases or those thicker than 2.5mm when using the Qi2 charger. Please avoid metal cases or any cases thicker than 2.5mm for the wireless earbud charger, as they might affect charging performance.
