Power generator

The power generator is a facility built in Fallout Shelter.

Overview
The power generator allows your dwellers to create power for your vault. It is one of the facilities available at the start of the game, and the first facility created in the tutorial.

Power is required for any room (excluding elevators and the vault door) to function. Without enough power, other rooms will stop producing resources.

Power Generation
To increase the speed at which power is generated. Place dwellers with better Strength in this room.

The power generator room like other rooms gains a production and upgrade cost bonus from being connected to another room of the same type and level. The rooms will gain a +2 production bonus for each connected room. Upgrade costs will be 25% cheaper for a double room and about 34% cheaper when upgrading a triple room vs upgrading 3 single rooms.
