I recently bought a QI compatible charger for my Nexus 5. On the box it states, that the "wireless charges up to 500 times".
I don't understand why the charger is only able to charge my phone 500 times.
What happens to the charger so that it does not work anymore? Can someone explain that?
Thanks for you help.
It is exactly this device: QI charger from ravpower
Edit 2: Looking at the website of the maker, it seems that they sell a mobile power bank as well. Perhaps they use the same packaging for the mobile power bank wireless charger and the wireless charger without battery.
Edit 3: I found the packaging on the internet.
