If you're doing the remote work thing like me, the PCH is a dream. Seaside cafes with Wi-Fi up and down the coast. Also hostels > Airbnb if you're solo and want to meet fellow travelers. Don’t rush Big Sur, find a spot to watch the sunset!

Yes to the portable charger! I'd also add a small travel adapter, comes in handy more than you'd think. And maybe a backup bank card just in case, ATMs can be sketchy.
