PowerBank Ampere port

[Georges98]

Hi, I use Xperia Z3 and I have a powerbank with 2 ports for charging 

1) 5V - 1A

2) 5V - 2.1A 
Can I use both of them ? 

Which port is the best for this phone ? 
Thank you

Hi @Georges98,

You can use both. The 2.1A will charge your phone faster so it is usually better to use that one.
