The signal strength of our MagSafe Charger can charge smartphones with Cases up to 3mm thickness. As long as the back of the Case does not exceed the thickness, and your case is not made of metal, the phone does not need to be removed from the Case . Please also make sure that there are no magnetic objects, metal rings or other interfering objects such as credit cards between the smartphone and the wireless charger!
Please also note that the magnetic hold function only works with iPhone models from iPhone 12 onwards and only works with thin Cases up to 1mm or with Cases which have integrated magnets, e.g. the official Apple MagSafeCases. We can also recommend our Slim Case! Thanks to the 1mm thin wooden layer, the full magnetic force between your iPhone and your wireless charger is maintained and ensures a stable hold.
