Both of these calculators are solar powered and include a backup battery for low light conditions. Both have 8-digit displays and sure-grip rubber keys. The credit card calculator has an ultra-thin design and turns off automatically when not in use. The larger pocket calculator includes memory and the display is tilted for ease in reading it.
