When using power bank to pay attention to those things:

1. Temperature changes on the power bank (conventional temperature -10 ℃ ~ 60 ℃, high temperature and low temperature will have an impact on power bank, serious power bank will be damaged)

2. Do not burn the cell at a high temperature (excessive temperatures can cause serious damage to the lithium battery, causing the electrolyte inside the lithium battery to evaporate, then leaking through the bleed valve on the battery, Cause a fire)

3. Can not be used for a long time in low temperature environment (power bank from a warm environment to a low temperature environment, or prolonged use of power bank in low temperature environment, in a certain temperature PCB may condense dew, Circuit board dew phenomenon more serious when it may lead to short-circuit phenomenon, so we need to pay attention to temperature changes, it is best to use more than 0 ℃ is more safe and durable.)
