What will happen if the ipad is connected to a 5v 20a power supply?

Question

Batteries

In theory, the ipad will simply take its 2a and everything will be fine. Isn't it the same? And just in case, I want to put a 2.5 A fuse.

Answer 1

Nothing will happen, I guarantee. If the ipad is an ipad, and the output PSU has a stable 5V.

Answer 2

Modern batteries are charged through controllers that control the current strength and charge level, balance the charge between banks and cut off charging when the battery is filled "to the top". So it is unlikely that something threatens your ipad.

Answer 3

If you just connect it like that, not only will he not get anything, but he won’t even “take” his 2A. Apple devices draw full charge current from branded (certified) chargers only. When charging from a conventional charger, the current is limited even more (something around 300-500 mA). That is why the Chinese write on many chargers that it does not support the iPad, although it gives out 2A.
Of course, this can be circumvented by adding a couple of resistors to the charger on the data bus, but these are unnecessary gestures.

Answer 4

According to the first screen, you enable the rule for all ports except Domolink. It seems to me (if this is the provider's port) then it is necessary! remove the sign
According to the second screen, why are you doing forward, and not input?
For the third nat, it is better to specify in dst.adress (external ip or incoming interface), otherwise it will work for outgoing connections
