SO. If you can charge it 4 hours a day from 10:00 AM - 2:00 PM it will take 25hrs / 4 = 6+ days to recharge to full capacity from dead. Probably about right if exposed to sunlight all day long, as if hang from backpack, it will not face sun directly for optimum charging, and if hiking won't always be facing the sun, and you might be walking under trees. However, it beats no solar charging. Bottom line is if you are a device junky and just have to be connected to big tech around-the-clock in the big city while allegedly enjoying the outdoors it might not meet be your cup of tea. **Q: Will it run a small 5v usb fan** A: We bought a couple of dpolar f621 5v fans and it ran them awesome during outage from hurricane. Fans are awesome too for 10 bucks a pair lol **Q: How does this changer perform in colder temperatures?** A: Hi, glad to get your inquiry. Because it's in the winter, so the solar charging speed will slower than that in the summer day because of the decrease of sunlight intensity. So i recommend you use wall charger to charge it in colder temperatures. And any problem arises, you can contact me directly at support@hiluckey.com or amazon message. i will do my best to solve your problem. hope this answer can help you. **Q: How does it store the power? Does it come with a battery or does the panel get connected directly to the mobile device?** A: you can use solar charging or USB charging to charge it. it's solar charger with 4 panels, the power bank is connected with the panel, and it's not detachable.
