I did a lot of research on portable chargers which lead me to believe that this one was going to be the best. It was working great the first month and a half then after that it was charging my phone really really slow. Even if there's no apps/programs running and/or when I shut off my phone it was still charging really slow. I'm not sure why bc I use its original cord when charging too. I had higher expectations for this product bc of its Anker brand and now I'm very disappointed in its speed and performance. I really thought I had the best portable charger when I purchased it. :(. May 30th update : however after writing the review above ^^^ Anker customer support contacted me via email and asked me a few questions then replaced it for me. I just received the replacement one today and have not used it yet. Hopefully this one will work better than the first. I appreciate their customer support services very much.
