300Wh portable solar storage plant usually contains a charger and a built-in lithium-ion battery. Such devices are generally lightweight and portable, and can be carried for use in the wilderness, camping, hiking and other outdoor activities.

The advantage of the storage plant is that it is portable and lightweight, easy to carry and use. In addition, since it uses solar energy for charging, it can be charged quickly in an outdoor environment, providing convenience for those who are active outdoors. The disadvantage is that the capacity is relatively small and cannot provide power for high-power devices, which has a limited scope of application.
