I bought a 9W samsung wireless charger to use with the 5W apple usb adapter but it only works with the original 9W samsung adapter.​

Reason being, I read on reddit that it's better to wirelessly charge your iPhone with 5W so that it doesn't overheat

will 9W be fine or does it frick up the battery? (i have the 13 mini)

So just to clarify you're asking if you can wirelessly charge your iPhone with the Samsung wireless charging pad and adapter?

Yes it's fine. It's just Qi charging. It will only accept the wattage it can use so no need to worry. Also you can use higher wattage adapters connected directly to the phone. The only time you might run into trouble is if you buy a counterfeit adapter and it's unsafe.
 
@russell_314 I'm asking if it's OK to charge with a 9W wireless charger. Some people say it's better to go with the slow 5W, it takes more time to charge but doesn't overheat the phone and drain battery health faster. But the 5W apple adapter doesn't work with my wireless charger
 
You need a 9W or 10W adapter to output to 5W or 7.5W (depends on the charger specs).

It won't work with 5W because the wireless charger itself needs power. This is why people don't recommend a wireless charger. The heat generated by the wireless charger causes problems in the long term.

You're best to just use the 5W adapter with a regular USB to Lightning cable.

From what I've gathered the only issue with wireless is the overheating part. Does it cause problems even if it doesn't over heat?
 
It's not really about "overheating" but rather excess heat.

With wireless and fast charging, you're generating excess heat. You're generating more heat than needed in exchange for convenience. Batteries are negatively affected by heat. If you don't mind reduced battery capacity over 1-2 years instead of 2-3, then use wireless charging.
 
Does it make a difference if the lightning cable is original or from a third-party like Baseus? (the 5w adapter i have is original)
