The generator includes three covered outlets to protect from harsh conditions, but the number of outlets is somewhat limited if you have many devices to connect.

Safety is enhanced by COsense technology that detects dangerous carbon monoxide and will shut the unit down if needed, along with low oil shutdown to protect the engine.
