The Zens ZESC02B / 00 charger works with my Nokia Lumia 820 perfectly. Although the charger see in the pictures quite what bigger, but among the search engine you will find the dimensions of the device, so that one knows what one expects. The processing and packaging is very neat, work does it flawlessly. As a tip: The included rubber sticker which is recommended for Samsung devices to instructions, is also reflected for Lumia 820 well, so it has two support points and does not rotate like a spinning top on the charger because the QI case of Nokia is easy arched.
