Pay attention to thunderstorms It is not a problem to use it indoors during thunderstorms. However, it is not recommend to walk in open areas and on high ground. For fear of causing hazards from electric arcs around the battery bank.
If it is not used for a long time, it should charge with 80% power and put in a dry place If the mobile power supply is not use for a long time, it will also consume part of the power. So it is very necessary to keep a part of the power. Do not put a particularly low electricity charge bank in an environment where the solar energy is irradiate and the water vapor is sufficient. This will seriously affect the service life and sometimes directly lead to the overall damage
Select a mobile power supply with intelligent protection. After a full charge, do not plug the mobile power supply into the AC power socket all the time. Especially the poor copy of the mobile power supply, if there is no charging protection, just wait to see fireworks. Overcharging causes the battery casing or pressure valve to bulge and crack, allowing oxygen to react with potassium atoms, and then explode. Consumers do not need to worry about security risks when using smart ic chips with multiple protections such as over-current protection. Over-discharge protection and voltage regulator protection.
