What wireless chargers support the iPhone X?

You can search for products that are compliant with the latest version of the Qi specification on the wireless power consortium website. Any product that supports the the Qi standard will work with the iPhone X. The iPhone X is designed to charge at a maximum speed of 7.5W. This means you should look for charging pads that are rated for the full 7.5W, but chargers with less output will also work.
