Beats X won't keep a charge, And now I won't charge

A couple of months ago I was on the road and I needed to charge my beats X, so I plugged them up to my portable charger and let them sit. I checked them 5 minutes later to see them flashing red and white. When I got home I plugged them up and tired to reset them many of times and they still didn't turn on nor charge. I even left them plugged up over night and still no charge,

And then 2 weeks ago I tried to charge them and they suddenly worked. They turned on and paired to my phone, once they died thought it started happening again. Red and white lights flashing, and no power is going to the battery, Did my portable charger break my beats X? Or is this a problem with beats
