After changing the Samsung Omnia 7 on the Nokia Lumia 1020, the old mini-charger has not had enough power to charge the phone. It was defakto even further discharged. The "Wicked Chili 2100mA" () adapter does have loaded the Lumia quickly, but the phone was also extremely hot and has, if the charger was removed, discharged directly back. Since I did not want to experiment, I now simply the original Nokia charger bought and finally loads my Smartphone back to normal. It is not hot, it loads in the same rate as at home on 230V adapter and holds the charge.
