I'm all for saving money too and I buy a lot of 3rd party accessories. But in this case though I really made a mistake of trying to save $15. You can say youre saving 100% but really that depends on the actual value. Thats like saying if you can get an OEM part for $2 but a knock off is $1 and the $1 dollar can break easily, you cant say you would still buy the $1 one. Now if you were saving $50 or more then yea that logic makes sense.
Here's another example, my friend has both iphone and an HTC phone. Instead of buying 1 charger for each she bought a 2 in 1 so she can save $. Turns out it was outputting too much amp on the micro usb side of the cable even though it says compatible. And guess what, she damaged her HTC phone. So even though she ended up saving $20 shes now out of a $500 phone. She didn't have insurance.
Anyhow after I saw what the charger did to my tablet I started googling for others and they all look identical to what I bought, so I'm assuming theyre coming from the same source in china. And the one on Amazon has the same issue. If you really still want save $ then atleast find one that doesn't look the same as the one I posted in the video.
This what I bought for your reference. 99% of the chargers sold on ebay or Amazon has the same wall plug.
Don't forget to give thanks if I've helped you in anyway...
