FAQ:

1. Q:Why working power bank is hot?

A:Electronic components work with heat. And Metal thermal conductivity is relatively strong,so metal material power bank will be a bit  then normal plastic power bank, but its Temperature is silimar with chargering mobile. Usually Temperature less than 40°C it’s normal and safe.

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.

5. Q:Why does it spend a long time when power bank ready to charge full?

A:Our power bank’s PCB has some protections. When the power is too low, the power current will weaken, and bright red. Charging for the power bank, power close to saturation, the current will weaken, and the circuit will be protected. Then avoid overcharge put the effects on the battery life.

(·Short circuit protection:Keep your device safe when short circuit problem is occur.

·Over charging protection:protect your gadget when it’s charge to long. this feature will automatically cut the power when battery is full.

·Temperature protection:A feature that can detect overheat on device when battery charging)

6. Q:Why there are some power bank’s charge and discharge’s speed become faster after using for a while?

A:Normaly,the using life of original A level’s chip is more than 500 times.when using times come near to 500 times its charge and discharge speed would be faster.if there are any power bank have this situation without using too much,then it can be scrapped.
