I liked this charger so much, I bought another to keep at home. The second one worked great for a couple weeks, but randomly stopped working. Now, when I plug something in, I get a brief moment of power to my device, followed by “188” on the charger. When I plug the charger in, it shows it has 95% charge, but will not progress any higher. I must have received a defective device, because this one has seen 0% of the wear and tear I put my first device through, and the first one works fine. All in all, a great product for the price. Just beware of these issues
