Last week is our holiday Mid- Autumn Festival , so happy to travel in HuiZhou and meet my friends .That was a sunny afternoon, when I came back to ShenZhen, I see a boy was calling to someone , while the power bank is charging mobile phone, I think it must be less power , but it is not a good habit ,because it is not safe, so when he finished calling , I talk to him immediately:

Hi, brother , when you are charging your mobile please don’t charge with power bank, it is very dangerous, because power bank is main build by battery , when you charge your power bank , it may be explode. He is a gentleman, so I told him much knowledge about power banks.

That’s a happy experience
