I have a Kindle Fire. I replaced the cable that came with it with this one. I think there was something wrong with the cable, which worked okay and first and for a while, as it was taking longer and longer to recharge the Kindle, and sometimes not at all. So, I thought this cable would be a good replacement and faster. It is working, but the disappointing part is that is not as fast as I imagined it would be. I had to replace the first cable anyway, so I guess the next step is to invest in the plug?
