200W outdoor portable energy storage emergency power supply

200W outdoor powerbank portable energy storage emergency power supply Precautions for use: If you do not intend to use outdoor mobile power for a long time, it is best to use 50% of the battery power storage. Storing the battery with empty capacity will make the battery unable to withstand any charge due to deep discharge. On the contrary, if the battery is fully charged and stored, the battery will lose part of its power, that is, shorten the use time of the battery. Another point to note is that outdoor mobile power is often used as a "fast charge", which is mostly used to respond to emergency charging. Long-term use may have an adverse effect on the phone battery. So we try to avoid excessive use of outdoor mobile power as a power source. However, it is more convenient to use outdoor mobile power to charge digital products while traveling or on business.
