§ 04The policyPower strips · surge · multi-plug

§ 05Quirks you won't read elsewherePrincess Cruises specifics
✦ Quirk
Naming collision: two different 'Sun Princess' ships exist
The 2024 Sphere-class Sun Princess is the new flagship. The 1995 Sun-class Sun Princess was a totally different ship (since sold). Articles about 'Sun Princess outlets' written before 2024 describe the older ship — check publication date before trusting outlet counts.
✦ Quirk
Sphere class has bedside parity — both sides equal
Most cruise ships put all the charging on one side of the bed. Sun Princess and Star Princess give each side 1× US outlet, 1× USB-A, and 1× USB-C. Couples don't fight over the lone bedside socket.
§ 06The Princess Cruises packTuned to this line

Princess permits this. On Grand class with 2 desk outlets and zero USB, this is the mandatory pack item — multiplies one outlet into four, hands you a usable cabin.

§ 07Questions about Princess CruisesReal answers
Can I bring a power strip on Princess Cruises?
Yes — as long as it has no surge protection and no indicator LED. Princess inherits Carnival Corp's policy: non-surge power strips and multi-plug adapters are explicitly permitted; surge protectors are banned.
Which Princess ship has the most outlets?
Sun Princess and Star Princess (Sphere class, 2024–2025) — 5× US + 1× EU + 4× USB-A + 4× USB-C with charging on both sides of the bed. Independent reviewers count 15 reachable charging points per cabin, the highest in mainstream cruising.
Do Grand-class Princess ships have USB?
No. Grand, Golden, Star, Caribbean, Crown, Emerald, and Ruby Princess all launched with two desk outlets and zero USB, and none of them have been retrofitted with USB at scale. Pack USB-A wall chargers — or upgrade to Royal class or Sphere class.
