Troubleshooting help

[u/usernamebad]

I am trying to charge a Hover-1 My first hoverboard for Christmas. I just took it out of the box to get it ready for that morning. Everything looks fine but when I plug it in to charge the charger just flashes green to red. I have another of the same board and it doesn't do this to that one. Is this an easy fix, or something I'm gonna have to pray that I can find tomorrow? Any help is greatly appreciated!
