My iPhone Charger is scratched up, would you still use it?

My clumsy dad always vacuums things up he shouldn't. I came back from doing errands and found my charger with black smudges and scratches. Little pieces of the USB adapter was chipped but nothing huge. I plugged in my phone to see if it still charged well and it did. I don't know if something might have messed up inside the charger an maybe mess up my battery but it charges fine. What's your guy's opinion, would you continue to use it?

As long as it is working and the part that goes into the iphone isn't broken it won't make a difference.yes i would use it

I think that that could cause a spark or something
