The Best Travel Power Strip

One specification decides this purchase, and it is not the outlet count. Whether the strip has surge protection determines whether it is allowed aboard a ship at all — and the two cruise lines that publish a rule publish opposite rules.

We have not tested this gear. Every figure here is compiled from published manufacturer specifications and published airline policies, and the arithmetic is public so you can check it. This page contains affiliate links — see the affiliate disclosure.

Check whether it has surge protection before you check anything else. Carnival’s published policy allows “extension cords without surge protection”; Royal Caribbean prohibits “extension cords, power strips, multi-plug outlets” outright. For a hotel abroad the decision is different again: a US strip changes nothing about voltage, so 230 V reaches whatever you plug in.

NTONPOWER 20W Travel Power Strip (4 outlets, 3 USB)

The three, as published

Manufacturer-published listing figures, compiled 6 October 2026. The Warn mark on the Ceptics is not a quality judgment — it flags the feature that gets a strip confiscated at a cruise terminal.

The cruise rule, from three lines’ own pages

“Cruise approved power strip” is a marketing phrase printed on listings, not a certification anybody issues. So we read what the lines publish. They do not agree, and one of them does not address it at all.

Why a ship cares about surge protection at all

A surge protector works by diverting excess voltage to ground. Ships run electrical systems that are not grounded the way a building’s is, and the published reasoning from the lines that ban them is fire risk on a circuit that cannot absorb the fault. Whether you accept the engineering, the practical consequence is the same: at the terminal, a bag scan that finds a surge protector on Royal Caribbean loses you the device.

On land the trade reverses. A hotel circuit you know nothing about is exactly where surge protection earns its keep, and the Ceptics is the only one of the three that publishes any.

The voltage trap, which is the real reason people buy the wrong one

A power strip does not change voltage. Nothing on this page is a converter, and the Ceptics listing says so in capital letters. Plug a 125 V-rated strip into a 230 V European socket through a plug adapter and you have delivered 230 V to the strip and to everything in it.

  • The NTONPOWER is rated 125 V. It is a US-voltage device. It belongs in a US hotel, a US cabin or a cruise ship stateroom, which run US voltage.
  • The Anker is split. Its listing publishes 125–240 V input on the USB ports — the half of the device that travels — while the two AC outlets pass mains voltage through unchanged.
  • The Ceptics is rated 110 V and ships with Type A, C, E/F, G and I plug adapters. The adapters change the shape of the plug; the strip still presents US sockets at 110 V rating.

The practical rule, which is the same rule as on charging devices abroad: read the brick on your own device. Anything marked 100–240 V is fine anywhere. Anything marked 120 V only — which is most hair dryers and some older appliances — is not made safe by any strip, adapter or plug on this page.

The Anker argument: a strip that is also the charger

The Anker is the heaviest here at a published 13.92 oz, and the only one that makes the weight back. It publishes 67 W shared across two USB-C ports, which is laptop charging, so it replaces both the power strip and the charging brick rather than adding to the pile.

Weigh it against what you would otherwise carry. The chargers in our ledger run 65–70 W in that bracket. If the Anker replaces one of those, the strip itself costs you a few ounces net, not 14.

If the problem is outlet count, buy on outlet count

Hotel rooms are built for lamps, not for a family with five devices. The NTONPOWER publishes four AC outlets and three USB ports in a 3.93 × 2.28 × 1.25 in body at 8 oz, with a 0.39 in flat plug and a wrap-around cord. That is twice the AC outlets of either rival in less than two thirds of the Anker’s weight, and it is the right answer whenever you are not short of watts.

What it will not do is charge a laptop. 20 W on one USB-C port is a phone, a watch and a pair of earbuds.

Can you take a power strip on a plane?

Yes, in either bag. A power strip contains no lithium cell, so none of the battery rules apply to it — those are covered on the TSA battery and electronics page. A power bank is the opposite case and must travel in the cabin. The only practical air-travel cost of a strip is the weight above, and on Hawaiian’s published 25 lb cap the Anker is about 3.5 percent of your whole allowance.

Every pick, with the working

Each entry below shows the published inputs, the four axis scores they produce, and what you give up. The order is the computed order, not a commercial one.

1 · A hotel or cabin where the problem is outlet count, not wattage

NTONPOWER 20W Travel Power Strip (4 outlets, 3 USB)

5.8

Four outlets and three USB ports at 0.5 lb, and the only strip here whose absence of surge protection is the selling point rather than a footnote. Read the cruise section before you believe the label.

Fits 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY. See the limits.

What it does well

  • 4 AC outlets plus 3 USB in 3.93 x 2.28 x 1.25 in and a published 0.5 lb
  • No surge protection, which is exactly what Carnival's published policy allows aboard
  • 0.39 in flat plug and a wrap-around cord, so it packs flat against a laptop

What you give up

  • Rated 125 V — this is a US-voltage strip and does not belong in a 230 V socket
  • 20 W on one USB-C port will not charge a laptop; this is a phone-and-watch device
  • The cruise-approved claim is true on Carnival and false on Royal Caribbean, which bans power strips outright
The arithmetic behind the score
  • Value not scored — No manufacturer-published price, so this axis is not scored.
  • Airline-fit breadth 10.0/10 — Fits the published carry-on limit at 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY
  • Carry efficiency not scored — No published capacity, so weight per liter cannot be computed.
  • Warranty & support 0.5/10 — 1.5 yr (0.5 of 6); no published repair route (+0); airline damage not covered (+0)

Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.

2 · A hotel desk with one outlet and a laptop, a phone and a watch to charge

Anker Nano Charging Station (6-in-1, 67W)

5.8

The only strip here that is also a 67 W laptop charger, which is the whole argument for it: one device replaces the strip and the brick. It publishes no surge protection, which on one of the three cruise lines we checked is exactly why it is allowed aboard.

Warranty 24 month product warranty published in the listing text

Fits 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY. See the limits.

What it does well

  • 67 W published across 2 USB-C ports — enough to charge a laptop, which no other strip here claims
  • 0.87 lb and 3.94 x 3.66 x 0.75 in, so it replaces a power strip and a charger rather than adding to them
  • The listing publishes 125-240 V input on the USB ports, which is the half of the device that travels

What you give up

  • The AC outlets pass mains voltage through unchanged — this is not a converter, and 230 V reaches a US appliance
  • Warranty figures disagree inside one listing: the text says 24 months, the specification table says 18
  • No surge protection, which is a liability on a hotel circuit even though it is what makes it cruise-legal on Carnival
The arithmetic behind the score
  • Value not scored — No manufacturer-published price, so this axis is not scored.

3 · A trip crossing more than one plug standard, where you want US sockets at the far end

Ceptics Travel Power Strip with International Plug Set

5.8

Skip this one. Skip it for a cruise. It is the best of the three for a trip abroad — grounded US sockets plus the five plug shapes a single European itinerary can cross — but it is the only one here that publishes surge protection, and surge protection is the exact feature both cruise lines that name power strips prohibit. One listing also publishes two different outside sizes for it, which is a small warning about how carefully the rest of its data was compiled.

The one here built for abroad: grounded US sockets plus the five plug shapes a single trip can cross, and the only one of the three that publishes surge protection. That last fact is also what gets it confiscated on a cruise.

What it does well

  • Includes Type A, C, E/F, G and I plug adapters — the five shapes that cover Europe, the UK, Japan and Australia
  • Published surge protection, which neither other strip here offers
  • 0.31 lb is the lightest of the three and it ships with its own pouch

What you give up

  • Surge protection makes it prohibited on both cruise lines whose published policies name power strips
  • Rated 110 V and explicitly not a converter — your 120 V-only hair dryer still will not work
  • One listing publishes two different outside sizes, which is a small warning about the rest of the data

Common questions

What is the best travel power strip?
It depends where it is going. For a hotel or a cruise stateroom where the problem is outlet count, the NTONPOWER publishes four AC outlets and three USB ports at 8 oz with no surge protection. For a trip where you also need a laptop charger, the Anker publishes 67 W across two USB-C ports. For a trip abroad, the Ceptics ships five plug adapters and publishes surge protection.
Are power strips allowed on cruise ships?
It depends on the line, and two major lines publish opposite rules. Carnival publishes power strips and extension cords without surge protection as allowed. Royal Caribbean publishes “extension cords, power strips, multi-plug outlets” as prohibited, permitting only certified device and USB chargers. Norwegian does not name them on its published prohibited list.
Why are surge protectors banned on cruise ships?
The published reasoning from the lines that ban them is fire risk: a surge protector diverts excess voltage to ground, and a ship’s electrical system is not grounded the way a building’s is. Whatever you make of the engineering, the consequence at the terminal is the same — the device is taken.
Can you use a US power strip in Europe?
Only with care, and never for a 120 V-only appliance. A power strip does not convert voltage. A strip rated 125 V plugged into a 230 V socket through a plug adapter delivers 230 V to the strip and everything in it. Check your own device’s brick: 100–240 V is fine anywhere, 120 V only is not.
Can you bring a power strip on a plane?
Yes, in carry-on or checked baggage. It contains no lithium cell, so the battery rules that force power banks into the cabin do not apply. The only real cost is weight — 5 to 14 oz across the three here.
Do I need surge protection in a hotel?
It is the one place it genuinely helps, because you know nothing about the circuit. The Ceptics is the only strip here that publishes any. The trade is that the same feature makes it prohibited on both cruise lines that name power strips at all.
