Best Chargers and Power Banks for Cruise Ships (No Power Strips Allowed)
Cruise ships ban power strips, but these multi-port chargers and power banks keep every device charged without breaking the rules.
Why Your Power Strip Won’t Make It On Board
You packed your six-outlet power strip, and the cruise line confiscated it at embarkation. Most major cruise lines have power strips and surge protectors in their prohibited items policies.
What cruise lines do allow are multi-port USB charging adapters, as long as they are a single plug design without a separate surge protection circuit. That distinction matters a lot when you are shopping. A GaN-based multi-port wall charger that plugs directly into the wall outlet is fine. A power strip with three outlets and a surge protector built in is not.
The typical cruise cabin has a few power outlets, sometimes a mix of US-style and European-style, and maybe a USB port or two built into the nightstand that tops out at 5W. That is not enough for a family traveling with phones, tablets, a camera, earbuds, and a laptop. The fix is a single multi-port charger that uses one outlet and charges everything simultaneously, paired with a quality power bank for the days you are ashore and away from the cabin.
Here is what actually works.
Multi-Port Wall Chargers for Cruise Cabins
For Families: 6 Ports, One Outlet
The Anker Desktop Charger 112W 6-Port USB-C Fast Charging Station is the most practical pick for cabins with multiple travelers. It delivers 112W total across six ports: three USB-C and three USB-A. Each USB-C port maxes out at 30W individually, and each USB-A port hits 18W. The whole unit measures just 3.0 × 3.2 × 1.3 inches, so it fits on a nightstand without taking over. At $39.99, it is the most cost-effective way to go from two outlets to six charging ports in one move.
- 6 ports: 3 USB-C and 3 USB-A
- 112W total output across all ports
- Max 30W per USB-C port and 18W per USB-A port
- Dimensions: 77 x 82 x 33 mm and weighs 302g
- Includes silicone cable organizer and 18-month warranty

For Couples or Light Packers: 65W in a Tiny Block
If the cabin is just two people and the device list is shorter, the Anker 735 Charger (Nano II 65W) punches well above its size. It uses GaN II technology to deliver 65W from a block that is genuinely pocketable. The three ports (two USB-C, one USB-A) handle a laptop, a phone, and a third device simultaneously. The foldable plug keeps it flat in a bag, and at $29.99 it costs less than most charging accessories sold in cruise ship gift shops. The 240V input means no voltage issues abroad, which matters if the ship itinerary includes European or Caribbean ports where you might also use it in a hotel.
- 65W max output power
- 3 USB ports (2x USB-C 1x USB-A)
- GaN II technology
- Foldable/retractable plug design

Budget Pick: Two Devices, Under $17
Not everyone needs laptop charging. For a traveler whose list stops at two phones or a phone and a tablet, the Anker 2-Pack Dual Port 12W USB-A Charger Block at $16.99 for two units covers the basics without overspending. Each block puts out 12W total across two USB-A ports with Anker’s PowerIQ technology to negotiate the right charge rate for each device. The foldable plug and 240V input check the cruise compatibility boxes. Getting two in the pack is useful: one for the cabin nightstand, one packed as a backup or shared with another cabin.
- 2× USB-A ports
- 12W total output
- Foldable plug design
- Input: 240V 1.2A
- 18-month warranty

iPhone Fast Charging Pick with Cables Included
The Anker iPhone Charger 2-Pack 20W Fast USB-C Charger Block is a strong option if USB-C fast charging for iPhones is the priority and you want cables included in the box. Each 20W block supports simultaneous USB-C and USB-A charging, and the pack comes with two 5-foot cables, which matters in a cruise cabin where outlets are rarely positioned conveniently close to beds. The 240V input and 3A amperage keep it ship-legal. At $16.99 for two chargers and two cables, this is the best value-per-port deal on this list if your device mix is Apple-heavy.
- 20W max output
- 2-port USB-C and USB-A
- Dual simultaneous charging
- Compact and portable
- 240V input 3A amperage
2-pack USB-C charger with 20W output, dual ports, includes 2x 5ft cables
The Four-Port Option for Mixed USB Households
The Anker Zolo USB C Charger Block 2-Pack 50W offers something the other chargers here do not: four ports on a single block, split evenly between USB-C and USB-A, at 50W max output. The ActiveShield 4.0 temperature monitoring and 240V input compatibility make it cruise-safe, and the foldable design keeps it from being a bulky presence in the outlet. For $29.99 for two units, a couple can each have their own four-port charger, or a solo traveler can use one and keep the other as a spare.
- 50W max output
- 2 USB-C ports + 2 USB-A ports
- 5A output current
- Foldable design
- ActiveShield 4.0 protection
- 240V input
Dual USB-C and USB-A charger with 50W max output and 4 total ports for multi-device charging.
Power Banks: Your Off-Ship Charging Strategy
Wall chargers solve the cabin problem. Power banks solve the shore excursion problem. A full day in port can easily run eight to ten hours away from the cabin, and that is a long time for phones doing navigation, photography, and mobile payments to go without a charge. Cruise ships do allow power banks in carry-on and cabin luggage, with TSA and most cruise line rules capping capacity at 100Wh (roughly 27,000mAh at standard voltage).
The Flagship: 140W, 24,000mAh, Laptop Capable
The Anker 737 Power Bank is the top-tier option for anyone traveling with a laptop or needing serious backup capacity. It carries 24,000mAh and delivers up to 140W via Power Delivery 3.1, which is enough to charge most laptops at full speed. The digital display shows real-time battery percentage and wattage, so you always know exactly where you stand. Recharge time from empty is listed at 52 minutes with the right charger. It is TSA carry-on compliant, and at $109.99 it is the most expensive item on this list, but for a traveler who cannot afford to have their laptop die on a sea day, the math works out.
- 24000mAh capacity
- 140W Power Delivery 3.1
- 3 USB ports (USB-C and USB-A)
- Digital display with real-time monitoring
- 52-minute recharge time
- TSA airline carry-on compliant

The Everyday Shore Excursion Pick: 10,000mAh 30W
For phone-and-earbuds travelers who do not need laptop power, the Anker Portable Charger 10,000mAh 30W Power Bank is a well-balanced option. It outputs 30W via USB-C, which is fast enough to meaningfully top up a modern iPhone or Android in under an hour. The 5.4-inch built-in USB-C cable means one less thing to pack. At 4.32 × 2.58 × 0.98 inches, it fits easily in a daypack or fanny pack. The 20W input speed gets it charged back up overnight in the cabin. At $29.99, this is the right price-to-capacity ratio for most travelers.
- 10000mAh capacity
- 30W fast charging output
- 20W input charging
- 5.4-inch built-in USB-C cable
- Bi-directional charging
- 4.32 × 2.58 × 0.98 inches

The Wall-Plug Hybrid: Power Bank and Charger in One
The Anker Nano 3-in-1 Portable iPhone Charger 10,000mAh is worth a close look for solo travelers who want to minimize the number of items they are managing. It has a 10,000mAh capacity, 30W two-way fast charging, a built-in USB-C cable, and a foldable wall plug that lets it charge directly from a wall outlet without a separate charger. That is meaningful on a cruise ship where every outlet is valuable: this unit can be the wall charger at night and the power bank during the day. At $49.99, it costs more than the standalone 10,000mAh option, but it replaces both a wall charger and a power bank at the same time.
- 10000mAh capacity
- 30W two-way fast charging
- Built-in USB-C cable
- Dual device charging
- Foldable wall plug
- 4.25 x 2.01 x 1.22 inches

How to Pick the Right Setup for Your Trip
The right combination depends on who is traveling and what they are carrying.
Solo traveler with a phone and earbuds: The Anker 735 Charger handles the cabin, and the 10,000mAh 30W Power Bank or the Nano 3-in-1 covers shore days. Total spend under $80.
Couple with phones and a tablet: The Anker Zolo 2-Pack gives each person their own four-port charger for $29.99, and one 10,000mAh power bank shared between two people is usually enough for a day trip.
Family with multiple devices including a laptop: The 6-port 112W Desktop Charger is the cabin anchor. Pair it with the Anker 737 Power Bank for laptop-capable backup, and add one or two smaller power banks for the kids’ devices on excursions.
Budget-focused traveler: The 2-Pack Dual Port 12W blocks at $16.99 cover basic charging, and the 30W Power Bank at $29.99 handles shore time. Total spend under $50.
One more note on the 240V input specification: every product on this list accepts 240V input. That matters because some cruise ships, particularly older vessels and those sailing European itineraries, only offer European-style 220V outlets in the cabin. A charger that only handles 110V will not work and could be damaged. All of these options are safe to plug in anywhere on board.
Pack smart, check the cruise line’s prohibited items list before you board, and keep the power strips at home.
