The connection between the magnet and the USB port seems loose. This thing snaps instantly leaving a usb connector stuck in my phone. It worked with every USB device I connected through it including Fast Charge 3, USB headphones and OTG. However, it also disconnected a few times while I was using it and I didn't press the connector hard. The USB tip is also huge, as you'd expect from a 10+10 pin connector, but it's not something you can use on a phone with a case. The contacts on the phone are quite open. I also found it too easy to pop it off center and not align the pins. Just in case it gets connected the wrong way it might not cause any problems, but it could also put 5V on the wrong pins and fry something in your phone/computer. Overall it will probably work for charging a laptop, but it didn't do well for me due to build quality and intermittent shutdowns. Why did they include a tote bag? I haven't changed my rating, I guess you can throw it away or use it for something else, but it's a product you put on your device and leave.
