Yes, wireless charging does work through this case in *almost* all situations. We've successfully tested charging on the most popular Qi wireless chargers, even with 3 cards in the case. See the video below which shows wireless charging working through our case on the top wireless charges on Amazon. However, there are two situations that could cause wireless charging problems (with all cases & phones).
First, wireless charging cannot work through those fancy metal credit cards. Even just one metal card will block wireless charging entirely. But you can charge through 4 regular cards just fine.
Second, not all Qi charges are created equal. We found that some of the poorly designed chargers couldn't charge through our thicker cases while the better Qi chargers worked just fine.
Here are links to two very affordable wireless chargers on Amazon (one dock and one flat) that work with all of our Silk cases.
