I wonder if that means, in a pinch, you could turn off the device to use an uncertified charger that iOS would block.
When traveling overseas a cheap charger died, partially frying my lightning port. The phone completely refused to charge and I grew more and more desperate as the battery slowly drained over the next day before eventually dying. Now trying again to charge the dead phone had a surprising result: it actually charged enough to boot up! Ridiculously: it then stopped charging once booted and drained again in about 2 minutes.
The solution I developed was to plug it in _then_ power it off and it would charge (slowly) while completely powered down. Removing power for even a moment would boot the phone and stop charging.
I'd absolutely guess that, in a pinch, you could charge your modern iPhone with a non-working cable if you did the same procedure: plug in, power off, let charge while off.
Or you charge it wirelessly (Qi charging).
