Can you ask refund?
This was a good read stupid purchases sure make for great stories.
What's wrong with RavPower? They seem to have good review on Amazon. Not that I would buy their product, I'm very satisfied with Anker, no intention to change. Just curious.
Ravpower has been known to have issues with certain batteries, also from a avid reviewer I will say that if you leave them a negative feedback they will press you to no end to change your review to positive and even going as far as having Amazon remove negative reviews.
