Natural Stone*
Kew Labs chargers have been installed on many natural stone surfaces but some natural stones like marble and quartzite may contain varying amounts of metallic content. To ensure compatibility with Kew Labs wireless chargers, it is recommended to conduct a test piece with your fabricator or supplier using the specific natural stone material you intend to use. This precaution will help verify that the material chosen falls within the parameters for successful Qi wireless charging.
