Property me the charger for the Nokia Lumia 930 bought, because the needs with Navi much electricity. So I thought 2.1A fit. But it creates not to charge the phone when the Navi runs on screen. Without Navi also a normal charger provides charging. I believe that the 2.1 A + 1.0 A not arrive at the mobile phone (not located on the cable). Then the part was after 3 weeks on all his mind. Now I use again my old charger plug, the times I got as a promotional gift. So from my point of view the device is not recommended.
