The outdoor solar lantern offers two power supply options: AAA batteries (not included) and solar batteries (included). In indoor settings such as dining tables and windowsills,2 AA batteries can be used to power the lantern. When the 2 AA batteries run out, you can replace them with new ones to keep using the lantern. For outdoor situations like yards and camping, solar energy can be used to power the lantern. Therefore, this lantern is an excellent choice for both indoor and outdoor use. Hanging solar lantern uses a larger and more efficient solar battery panel, which collects sunlight during the day to charge it fully. It automatically turns on for 6-8 hours at night and can work normally even in winter.
