2. Q:what’s temperature of power bank?

A:Working environment temperature:0°C-40°C.IF environment temperature less than 0°C,its power transfer speed will be slow;and environment temperature higher 40°C, Battery heat can not be distributed.When heat is gathered to a certain degree, there will be a risk of smoking and even explosion.

3. Q:The notes of using power bank.

A:Fall, high and low temperature, piercing, fire, long-stalled will affect the security of power bank. In this several, It should not be ignored that the influence of high and low temperature for power bank safety use, especially in summer, don't put the power bank in the car.
