No Keep your phone charged on the go. If your phone is anything like mine, it constantly needs to be charged. I always keep a charger in my car. This one comes with a nice, thick charging cable too. I will admit, it was a bit hard to push in. I almost thought it wouldn't fit. I had to really push it in there. It charges my phone pretty quick so that's definitely a plus. Also has the 2.1A output for tablets as well. You can charge 2 gadgets at the same time too.
