Watt
Watts are electrical charges that all Chibi-Robos must depend on.
Purpose
Watts are a Chibi-Robo's life energy. It powers them up to keep them running and acting so they can continue performing. Since Chibi-Robos are autonomous robots, they slowly lose watts with each action they perform, including standing still. Should a Chibi-Robo be hurt in any way, they will also lose watts as well. Watts themselves have a couple of ways of being produced. Blooming Chibi-Robo Houses can convert Happy points into Watts, with a conversion rate of about 10 happy points equalling 100 Watts. In Welcome Home Chibi-Robo!, trash can be compacted in order to convert into Watts for a whole entire house and Chibi-Robo. A full vaccum bag is enough to recharge a house's energy to it's Maximum, while regular trash only gives off 10 to 50 Watts.
Watts are also used as currency in Chibi-Robo!: Park Patrol.
Charging watts
To recharge watts, the player can plug their Chibi-Robo's Chibi Plug into an Outlet to recharge their electrical energy.
In Chibi-Robo! Photo Finder, the only outlet that the player can plug into is in the Curator's Office. Not only that this is the only method of recharging Chibi-Robo, there are multiple batteries scattered throughout while exploring. If Chibi-Robo picks up a battery, it recharges him to 100 watts. In all games, Chibi can upgrade his battery life by progressing through the game, allowing the player to explore even more without the worry of running out of energy quickly. The base amount of watts varries from game to game. In park patrol, begining battery life is 100 watts, while in "Plug into adventure!" and "Welcome home Chibi Robo!" it's 80.
Running out of watts
In Chibi-Robo! and Chibi-Robo! Photo Finder, should the player run out of watts, Chibi-Robo will power down and result in a "Game Over". The player would be returned to their Chibi-House or home for a emergency recharge by Telly Vision or Telly.
If the player runs out of watts during a job in Chibi-Robo! Photo Finder, Chibi-Robo will lose all progress made within the job and will earn zero Happy Points.
