Charges my iPhone quite well. Only been the first few days of using. The size and round corners make it very pocketable. The product quality and make seem quite good. There is one part I am worried about and that’s the lightning cable. The design of the product is using the cable as the lanyard of the battery. It’s kind of clever but also worrying that the cable might not handle that much abuse over time. The version I bought has a USB-C and lightning port to charge the battery. The lightning port is super convenient for iPhone users. I only need to carry one cable now! Yay.

Does exactly what it’s supposed to do. What is nice is that it is quite compact.
