The Sega Nomad is a portable version of the Sega Genesis. It is a cartridge based system and uses the Sega Genesis cartridges. The unit can also be plugged into a television and has an optional second controller port for a second player. The unit itself came with a power cord and a pattery pack requiring 6 AA batteries and gives you a playing time of roughly 1 hour. An optional NiMH rechargable battery pack was also available for the unit.
