Review on ECEEN 13W Dual Port USB Universal PowerPort Solar Mobile Charger for iPhone 7/7 Plus/6S/6/6 Plus,iPad Pro, Android Phones Nexus 5X/6P Kindle and Other 5V Digital Devices - Black by Pamela Ervin

Much more 'comprehensive' than there was in this size, weight and price a few years ago. My only complaint, and I only mean it, is that there should be 2 "retractable stand loops" (sorry, don't know what else to call it) compared to the one currently included. If you only have one, the device will often fall which can ruin the whole charging experience as the device is no longer facing the sun in this case.
