I purchased the Wireless Charger Stand with Power Adapter to charge my iphone 12 max with an Otterbox Defender case, it had indicated that it would. When I put the phone on it, it only shows a blinking blue light, which I found that something metal won’t let charge as to the reason. Is there another model that will charge through an Otterbox defender case?
The wireless contact point on the new iphones is slightly different from where it was on the older phones. So try putting your phone horizontally and see if it charges, if it does then you know it works and isn’t because of the case but rather Apple moving the vertical charging pad. Some have gotten away by angling the phone slightly against the stand, you can try that and see if it helps.
