The Bushnell PowerSync SolarBook 850 is equipped with flexible, foldable solar panels that charge integrated dual lithium-ion batteries. Once the SolarBook 850 is fully charged, you can plug your portable USB-powered devices into one or both of the USB ports for charging. If there's no sun, you can use the device's micro-USB port and a wall outlet to charge the integrated lithium-ion batteries before you head out for the day. This means that no matter the conditions, you can head out into the field with enough juice to recharge multiple devices. Plus, the SolarBook 850 solar panels conveniently fold up into an integrated case that can be easily packed away when not in use.
