When I traveled, I took with me one charger (
EP-TA20JWE It's like EP-TA20EWE оnly with another plug) and several different USB cables: type C for Galaxy A7, micro-USB for Kindle, bluetooth headset, etc. All my gadgets are charged from this device without failures and only for the iPad mini 2 I took the charger Apple, iPad charges very slowly from Samsung charger They are not friends.
