Both phones were revealed in early September, and will be released on various carriers beginning in November.
The Nokia Lumia 920 and 820 don't have built-in wireless charging, but require a charging shell and base to achieve the function.
New details emerged on Thursday when Nokia announced pricing for the devices' wireless charging kits.
Lumia 920, 820 charging shell and base prices
The Nokia Lumia 920 and 820's charging shell resembles a standard phone case, and costs $32 (GB £19.99, AU $31).
The charging shell appears to come in red, yellow, white, blue, and black, but aside from color differences there's only one type of shell.
The wireless charging base is another story; it comes in three varieties.
The plain, flat "plate" option is $88(GB £54.99, AU $86), while the "stand" - which stands the phone up while it's charging - is $112 (GB£69.99, AU $109).
The luxury option is the wireless charging "Fatboy pillow," which provides a soft place for the Lumia 920 and 820 to rest and charge for $128 (GB £79.99, AU $125).
Wireless charging on its way
Nokia's wireless charging accessories are available for pre-order now, though no formal release date has been announced, either in the U.K. or the U.S.
And the prices Nokia announced on Thursday apply to the U.K. only - prices in other countries could vary greatly.
