Magnetic PowerBank

Used it once for a very short time and it almost destroyed my phone by overheating it. My phone kept shutting down every few seconds for a few hours after I used this until I was able to put it in the freezer to cool it down long enough to keep it from shutting so I could do a factory reset. I contacted Ekon customer service and they told me my only recourse was to ship it back to China at my expense which would have cost more then I paid for this.
