A compact multi-port USB-C charger is usually a better cruise-cabin solution than carrying a power strip. Look for enough total wattage to charge your laptop, phone, camera accessories and power bank, while checking how output is divided when several ports are used.
Understand shared wattage
A charger advertised at 100W may not provide 100W from every port simultaneously. Read its output table so you know what happens when a laptop and several smaller devices are connected.
Check the ship before buying
Expedition vessels differ in socket type, location and permitted electrical accessories. Confirm the vessel’s current guidance. Cruise operators may prohibit extension cords, surge protectors or unapproved multi-outlet devices.
One charger can reduce baggage
A good GaN-style multi-port charger can replace several bulky bricks. Bring the correct cables and one spare for any connection your photography workflow depends on.
GaN can reduce the charger pile
Modern gallium-nitride chargers can provide high USB-C output from a compact body, useful when cabin sockets are limited. Check each port’s output when several devices are connected simultaneously; headline wattage is often shared. A charger is not the same as a multi-socket extension. Verify your ship’s electrical rules before bringing power strips or surge-protected devices.
Check output with every port occupied
A charger advertised as 100W may not provide 100W to each device simultaneously. Manufacturers divide total output across ports in different ways. Check the multi-device power table for the exact charger, especially if you expect to charge a laptop, camera batteries and phone at the same time.
