Today I'd like to share with you some knowledge about power banks as below.Sincerely hope it is helpful for you:

-Yes,but must use qualified power banks.Some factories produce power banks with bad quality materials,no protection in circuit,it's very dangerous;
What is the voltage/current of output of power banks?
-5V 1A.Now there is also the fast charging power bank with 5V 2A or 5V 2.1A;
Is 2A output power bank harmful for mobile phone;
-If your mobile phones can support 2A output,just a little affect to mobile phones' battery,almost can be ignored;
If there is heat when charging for cell phones with power banks?
-Yes,a little,since the components and parts of power banks have resistance.While if you feel unusual heat,then must stop charging immediately;
If we can take power banks by air?
-Yes.The conditions include:a.Power banks are good quality,no abrasion; b.Factory should mark the correct voltage and current of power banks; c.Capacity of power banks are not higher than 20000mah; d.The power is less than 100w,each passenger can take 2pcs power banks.If it is 100w-160w,only can take 1pc power bank; e.The power bank should be taken by yourself,cannot be consigned.
