I bought about a year ago several Ladepads this series in white. First, they are not recognized by all of our QI-enabled devices, secondly, a significant warming is loading with most phones noticeably. Which pad which phone works and how strongly it is heated to pure luck and will have to try by rausgefunden be. Therefore, I'd bet on a strong series dispersion in the production.
Meanwhile, in one of the pads and the electronics has blown and has melted parts of Ladepads. Interestingly, this happened not during charging, so that fortunately no damage phone or even a battery was set on fire.
Still, I can only advise against buying this Ladepads.
