This morning 12yo was charging his personal blender so he could make a breakfast smoothie, and it wouldn't charge. 12: I'll go upstairs and see if any of the other USB cables work better. Me: Hope it's not the charging port! 12, minutes later: Well, i have good news and bad news. Me: ok, bad news first 12: well, I ran some tests. And it turns out that i am REALLY HUNGRY. Good news is, it's the cable. The End.
