Should the solar power bank be activated?

What is activated is not solar energy but the lithium battery. The lithium battery has stored electricity when it leaves the factory. However, to fully release the energy storage capacity, it must be completely discharged before it can be activated. once is enough for a cell phone, because yours is 50,000 millimeters. The security capacity is large, so more times are needed. In the future, do not use it before recharging during normal use. Keep it charged when not in use. Remember to charge it occasionally when not in use for a long time to extend its service life. As for the charging time, it depends on the amount of watts of your solar panel and the sufficient amount of sunlight. Also, how much does your monocrystalline silicon panel and a 50,000 mAh lithium battery weigh? Additionally, those with more than 20,000 mAh will not beallowed to board the plane, which is really inconvenient. If you frequently do outdoor activities, Zhongyi Xingye gallium arsenide thin film solar charging paper should be more practical. In fact, with the development of solar cell technology, many new technologies have been widely used.
