if cranking for emergency power isn’t really your cup of English Breakfast, then perhaps, Bushnell PowerSync Solar Chargers might be the one other obvious choice if you planned to stay off the grid. the Bushnell PowerSync Solar Chargers are available in two models: the SolarBook that has a book-like form factor (hence the name) and the SolarWrap that can be rolled up into a convenient package for storage and transportation. the SolarBook comes in two sub-models, the SolarBook 600 and SolarBook 850 and the SolarWrap is available as SolarWrap 250 and SolarWrap 400. common features include high solar collectivity panels (even in less than full sun conditions), foldable or wrap-around solar panels for ease of storage and protection while in transit, power gauge to keep you informed of the battery level, integrated lithium-ion battery for storage of electrical charge (dual lithium-ion for the SolarBook), and USB ports for charging your devices (two on the SolarBook and one on the SolarWrap).
the solar cells are independently wired so that even if a cell or two gets damaged, the charger can continue to function. differentiating the two sub-models is the solar recharging time: the 600/250 model takes 6 hours to fully charge under the sun, while the 850/600 only requires 3.5 hours. of course, all the devices can be recharged via a wall outlet if there is any at your disposal. there’s an even more compact solution, dubbed the SolarWrap Mini that offers the same performance as the regular SolarWrap, but takes around 10 hours to fully recharged under the sun. prices start from $89.99 for the SolarWrap Mini and runs up to $356.95 for the SolarBook 850. scroll down for a few more look and while you are there, do check out the product intro video to learn more.
