I've been turned off anker ever since my first purchase with them. After 8 or so years, my OEM hp laptop charger died and I purchased an anker. It literally fell apart within a couple weeks of using it so I wrote a bad amazon review. They wound up sending me another one and the exact same thing happened to that one in two weeks. I'm guessing every time I charged my laptop, the glue holding the charger together would melt, resoldify when it cooled down, then eventually wear down (in approx 2 weeks!). Long story short, I've never purchased another one if their products and will continue to refuse to do so.
