WATCH: [All Kings vs. Sharks highlights]
Anze Kopitar scored two goals and had an assist, and Jonathan Quick made 24 saves for Los Angeles, which outshot San Jose 17-6 in the first period and took control of the game.
Dustin Brown and Nicholas Shore scored for the Kings (2-0-0).
"We're just trying to get up the ice quicker," Brown said. "My goal was the result of just transitioning from a turnover deep in our zone and getting up the ice and just attacking the net. We had a lot of Grade A scoring chances. I think it was a big difference from what we would consider our [38]-shot totals last year. Like, the type of chances we're getting."
Mikkel Boedker scored for the Sharks (0-2-0), who lost 5-3 at home to the Philadelphia Flyers on Wednesday.
"That was just horrible," forward Logan Couture said. "You can't make excuses because that was a very, very poor effort from the first minute to the 60th minute, from the power play to the penalty kill. It was just garbage hockey from us."
