iPhone won't charge in Computer/USB

Hey

Peeps! I have an iPhone 7 Plus. It will charge perfectly when plugged

directly into the wall but won't charge or detect on my MacBook (or my

PC).

1- It's not the iPhone cable as I've tried my other iPhone on the cord and it works perfectly.

2- It's not the Macbook because as I previously stated my other phone works on it.

3-I'm going to assume it's not the phone's charging port because it

charges perfectly in the wall. It just doesn't charge when plugged into

my Macbook's USB port.

4- It's not the Macbook's USB ports as I've tried them all with my other phone.

Can

someone PLEEEEAAAASSSE help me!!!??? I'm trying to restore some things

from iTunes that I previously backed up but I can't get my Macbook to

recognize my phone.
