Is the iPhone charger waterproof?

I spilled a bit of juice on the charger's thunderbolt tip, I inspected it and it didn't seem like it could let anything in but to be safe I drowned it in rice. I couldn't find much online so I hoped anyone would know more, would it fry my battery if I tried to use the charger? Thanks.
P.S. The charger is plugged in the original adapter, not a wall socket.

If it was plugged in when you got it wet… Then the charger itself might have damage (i even doubt that) but it will not hurt you phone… It'll either work or not.

If it wasn't plugged in when it got wet, then for sure it's fine as will be your phone

No charger is waterproof.

If it works, don't worry about it.

If it fails, replace it.
