This charger has two energy sources one is solar and the other electric. If you are outdoors for an extensive period of time like hiking or working outdoors like a gardener this type of charger is great. There is also a plugin wall adapter so it can be charged electrically as well. In general solar panels require full sun and that is sometimes difficult to achieve continuous hour after hour but this will charge. It is 5000 mAh and can charge a phone several times before needing to be recharged.
There are dual ports for multiple devices.
The package comes with charger, plugin adapter and cable.
