Four cables of mine do not work, two C to Lightning, one USB to Lightning, and one quad lock USB to lightning.
Damage was cause when I emergency charged during wet conditions, apple help said this can cause damage and the Apple Store I went to said this can cause damage, and it did - I simply do not have time to send my phone in at this moment, but will in a month when I return from my trip.
Hope that clears things up for you
After using it for two days now, the in-between connectors get extremely hot - I guess I have to make sure they don’t touch anything else including my skin 😅
