Thanks for the quick reply.
Turn it on? When I use it for my phone, I just plug it in and it works. Wasn't aware it had to be turned on.
I'm traveling and do not have the instructions with me - how do I turn it on? I've tried holding the button, or double clicking, or whatever and it still charges wrong way.
edit: my phone is a Galaxy s8+, so it is using usb-c to usb-c, same port I would use for the laptop charging.
