TESSAN 140W GaN Universal Travel Adapter: A Royal Caribbean-Compatible Cruise Charger
The TESSAN 140W GaN Universal Travel Adapter combines worldwide plug compatibility with a powerful USB charging setup that looks particularly well suited to Royal Caribbean’s current cruise-ship power rules.
It provides one AC outlet, three USB-C ports and one USB-A port, allowing up to five devices to connect at once. Even better for travelers carrying laptops and other higher-powered gear, its USB-C charging system can provide up to 140W of total output.
And despite the “travel adapter” name, this isn’t only useful overseas. Its retractable North American plug means it can also plug directly into a standard US-style cruise cabin outlet, making it a practical primary charger for American cruisers.

One AC Outlet + Four USB Ports
The TESSAN adapter includes:
- One universal AC outlet
- Three USB-C charging ports
- One USB-A charging port
- Up to 140W total USB charging output
- Retractable Type A, Type C, Type G and Type I plugs
- Replaceable fuse with a spare fuse
- No cord
- No surge protection
That makes this much more than a simple plug adapter. The high-output GaN USB-C charging system can potentially replace a separate laptop charger while the remaining ports handle phones, tablets, watches, power banks and other travel gear.
Should Work on Royal Caribbean and Celebrity Cruises
The configuration of this TESSAN adapter lines up very closely with Royal Caribbean’s current guidance.
Royal Caribbean allows a properly marked adapter with one AC outlet plus up to four USB-A or USB-C charging ports. This TESSAN model has exactly one AC outlet and four total USB ports. Product photos also show recognized conformity markings on the adapter.
| Applicable Requirement | TESSAN 140W Adapter | Check |
|---|---|---|
| Single AC outlet | One universal AC receptacle | ☑ |
| Four or fewer USB ports | Exactly four: three USB-C + one USB-A | ☑ |
| Recognized safety or conformity marking | Product photos show CE and UKCA conformity markings | ☑ |
| No extension cord or power-strip design | Plugs directly into the outlet | ☑ |
That puts this adapter right at the maximum USB-port count currently allowed alongside a single AC outlet.

The specific one-AC-outlet and four-USB-port guidance discussed here comes from Royal Caribbean. Celebrity Cruises has similar restrictions on prohibited power strips and electrical devices, but travelers should always verify current requirements with their specific cruise line.
Cruise-line policies can change, and individual electrical items remain subject to inspection and final approval by ship security.
Works with Both North American and European Cruise Cabin Outlets
Don’t let the “travel adapter” name make this seem like something that is only useful overseas.
The TESSAN includes retractable plugs for both North American Type A outlets and European Type C outlets. That makes it particularly useful in cruise cabins, where you may have access to both a standard North American outlet and a 220V European outlet.
You can plug the adapter into the standard North American cabin outlet just like a conventional charger, or use the European Type C plug to take advantage of an additional outlet that might otherwise go unused.
That flexibility is especially valuable under Royal Caribbean’s current power rules. Many products designed to add charging capacity use a power-strip or multi-outlet configuration with two or more AC receptacles. Those designs can run afoul of Royal Caribbean’s prohibition on multi-plug outlets.
Finding a compact charger that provides only one AC outlet while also adding several USB ports is surprisingly difficult. This TESSAN model is unusual because it provides one AC outlet plus four USB charging ports while remaining usable with both North American and European wall outlets.
For a Royal Caribbean or Celebrity cruise, that makes it much more than an international travel accessory. It can serve as a primary cabin charger regardless of which of those two common outlet types you decide to use.
Remember: The adapter changes the plug configuration but does not convert voltage. When using a 220V European outlet, anything connected to the AC receptacle must be compatible with that voltage.

140W GaN USB-C Charging Can Replace a Laptop Charger
One of the most interesting features here is the built-in 140W GaN USB charging system.
The USB-C1 and USB-C2 ports can each provide up to 140W when used individually, while the adapter’s total USB output is limited to 140W. That gives it enough power for many USB-C laptops while still providing additional ports for phones, watches and other travel gear.
When multiple USB devices are connected at the same time, the available charging power is divided among the ports.
For travelers who already charge a laptop through USB-C, this could eliminate the need to pack a separate laptop power brick. That makes the TESSAN especially appealing for international trips where a cruise is only part of the itinerary.
Useful Beyond the Cruise Ship
Retractable Type A, Type C, Type G and Type I plugs make this a true universal travel adapter rather than a Europe-only accessory.
That means the same adapter can be useful before and after a cruise in hotels throughout Europe, the UK, Australia, the United States and many other destinations.
The European Type C plug is particularly useful aboard cruise ships equipped with a 220V European cabin outlet, giving you another charging location without creating multiple AC receptacles.
Important: This Is Not a Voltage Converter
The TESSAN adapter changes the plug configuration but does not convert voltage.
The adapter is designed for international input voltages, but anything connected to its AC outlet must also be compatible with the voltage supplied by the wall or cruise-cabin outlet.
Check the device or power supply for an input rating such as 100-240V before connecting it to a 220V outlet. This is especially important with hair dryers, curling irons, straighteners and other higher-powered appliances.
USB devices powered directly through the TESSAN’s USB ports receive the charging output produced by the adapter itself.
Bottom Line
The TESSAN 140W GaN Universal Travel Adapter checks a lot of boxes for cruise and international travel.
Its combination of one AC outlet, four USB ports, visible conformity markings and powerful 140W GaN USB-C charging fits Royal Caribbean’s current outlet-and-port limits while providing enough charging capability to potentially replace several separate adapters and power bricks.
For a trip that combines a Royal Caribbean or Celebrity cruise with international travel before or afterward, this is an especially interesting all-in-one option.
