Early in our testing, this was our favorite lightweight, ultra portable solar charger. The CIGS (copper-indium-gallium-selenide) solar panel is flexible and rolls into a compact tube for packing, giving it a great panel size to packed size ratio; there's a battery that allows for charging at night when you're back at camp; and the whole thing is extremely lightweight.
Among the fleet of panels we tested that include a battery, the Poweradd Apollo 2 edged ahead of the SolarWrap in several ways, including durability over time, but also in the amount of time spent charging the battery vs. the amount of charge to our devices. That is to say, we found we were always chasing a charge with the SolarWrap Mini while with the Apollo 2, since it holds more equivalent smartphone or tablet charges, we had more time to catch up on sun time before we lost the ability to charge a device at least once.
Unfortunately, the SolarWrap proved to have some significant durability issues, likely attributed to weak electrical components. After a couple of months, the panel would not charge the battery, nor would plugging it directly into a wall socket charge the battery, even though the charging light still lit up. Fortunately, the charger comes with a 1 year warranty.
For light and infrequent use, this solar charger will likely fit the bill. It is not a rugged or durable solar charger, but the concept and design is great. We hope to see some improvements to the durability, as it really is a great idea.
