Patently Mobile reports that from the design of this device, it would support all Qi-compatible smartphone, tablet and wearable in the market because it supports both inductive and resonates modes of wireless charging, which are docile with the Qi standard. The design of this device is quite simple, there are two coils housed within the unit and both of them supports inductive and resonate charging thus the pad can switch automatically between them whenever the user wants it to.
