The Nokia Lumia 820 shares with the "big brother", the Nokia Lumia 920 the ability to be recharged without the need to physically connect the power supply. To take advantage of this feature you will need to use one of several accessories for the purpose, from the base and the charging stand provided by Nokia.
The Lumia 820 also offers the possibility to replace the back cover, rapidly changing look. Users who want to take advantage of this interesting possibility of customization will have to choose carefully the extra cover since not all are integrated with wireless charger.
