I WAS SO HAPPY with my TeckNet 9000mAh USB Battery backup AT THE BEGINNIG then a week later I had to buy a new cable (the one which came with it was very poor quality) I was a bit upset but I thought my battery backup still working pretty well so its ok.
Well few weeks later I realized I could use much less then before, the battery died so quickly (few hours in my bag without charging my phone). 3 month later it didn't work at all.
I think the most of the people wrote their reviews few days after they tried the product. Good price good reviews so you think its fine but if you want to use it more then few weeks I think you should choose another one.
