I’ve been in plenty of situations where a standard power strip just won’t fit behind a nightstand or under a desk. That’s why I tested the Addtam Cruise Essentials – Flat Plug Power Strip, Addtam 5 ft Ultra Flat Extension Cord with 6 Outlets Extender, No Surg, and its ultra-thin 0.35-inch plug is a real space-saver. With 6 AC outlets and a 5-foot flat cord, it handles up to 1875W, which is plenty for charging phones, laptops, and small appliances.
This power strip is specifically designed for cruise ships because it has no surge protector, which many cruise lines require. It’s also great for college dorms, RVs, or any tight spot where you need extra outlets without blocking adjacent plugs. The only trade-off I noticed is that it lacks USB ports, so you’ll still need your own charging bricks for devices. Let me walk you through what makes this little strip so handy.

What Stands Out — Key Features
- Ultra Flat Plug: The plug is only 0.35 inches thick with a 45-degree right angle design. I could slide my bed right up against the wall without the plug sticking out.
- 6 Outlets on 3 Sides: The outlets are spaced on three sides so bigger adapters don’t block each other. I plugged in six devices without any interference.
- No Surge Protection: This is intentional for cruise ships that ban surge protectors. It’s a must-have if you’re sailing and need extra outlets in your cabin.
- Mountable Design: It comes with screws and keyholes on both ends, so I mounted it under my desk to keep cords off the floor. Took me about two minutes.
- Safety Certifications: It’s ETL listed and has overload, short-circuit, and over-voltage protection. I feel safe leaving it plugged in overnight.
- 5-Foot Flat Cord: The cord is ultra-flat and lies flush against the baseboard. It’s long enough to reach from behind a dresser to the wall outlet without a tangled mess.
- Lightweight and Compact: At just 5.1 inches long and 1.4 inches wide, it easily fits in my carry-on bag for trips. It’s barely bigger than a smartphone.

Pros & Cons — The Honest Take
✅ What I Like
- The 0.35-inch flat plug let me push my dresser flush against the wall without bending the cord.
- At 5.1 inches long and 1.4 inches wide, it’s small enough to toss in a backpack for travel.
- Mounting it under my desk with the included screws took me less than two minutes.
- The 3-sided outlet layout gave me room for six bulky chargers without any blocking.
- It’s ETL listed and has overload protection, so I trust it for overnight charging.
❌ What Could Be Better
- There are no USB ports built in, so you still need charging bricks for phones and tablets.
- The lack of surge protection means I wouldn’t use it for a TV or computer setup at home.
- The cord is only 5 feet, which might be too short if your outlet is far from your desk or bed.
For me, the space-saving flat plug and compact size make this a winner for travel and tight spots, but the missing USB ports and surge protection keep it from being a full home-office solution.
⚖️ How Does It Compare?
I picked two other Addtam power strips that are close cousins to the Cruise Essentials so you can see how they stack up. The first one is another flat plug model, and the second includes surge protection for a different use case.

🔵 Alternative 1: Addtam Flat Plug Power
Best for: Someone who needs a longer cord or wants USB ports built into the strip.
Key specs: Also has a 0.35-inch flat plug, but comes in cord lengths from 1 ft up to 25 ft. Includes 3 USB ports.
Where it beats the main product: The built-in USB ports mean you can charge phones and tablets without a separate brick.
Where it falls short: It still lacks surge protection, so it’s not a home office solution for sensitive electronics.

- 【10 FT Long Extension Cord】 - This long power strip with 10ft is long enough to make it more...
- 【3 Side Design & Widely Space】- Multi sided compact power strip with widely space fits large...
⚪ Alternative 2: Addtam Surge Protector Power
Best for: Home or office use where you need to protect computers, TVs, and gaming consoles from power spikes.
Key specs: Has a surge protector rating (check listing for joules), 6 outlets, and a standard plug that is not flat.
Where it beats the main product: The surge protection gives me peace of mind for my desktop computer and monitor setup.
Where it falls short: The plug is bulky and sticks out from the wall, so it won’t fit behind furniture like the Cruise Essentials does.
If you’re going on a cruise or need to hide a strip behind a bed, I’d stick with the Cruise Essentials for its slim plug and no-surge design. But if you want USB ports for travel, grab the Addtam Flat Plug Power instead, and if you’re protecting a home office, the Surge Protector model is the safer bet.
How It Actually Performs
Flat Plug & Space Savings
The 0.35-inch ultra-thin plug was the feature I was most curious about, and it delivered exactly as promised. I slid my nightstand flush against the wall with zero cord bending or gap — something I’ve never managed with a standard plug. The 45-degree right angle also meant the cord ran straight down instead of sticking out sideways, which freed up space for a lamp and alarm clock on the same outlet.
Outlet Layout & Device Compatibility
With 6 AC outlets spread across three sides, I plugged in a laptop charger, phone charger, tablet brick, desk lamp, fan, and a small printer without any of them blocking each other. The strip handles up to 1875W and 15 amps at 125 volts, which is plenty for my desk setup. I did notice that larger wall warts still cover one adjacent outlet, but the 3-sided design minimizes that problem better than most strips I’ve used.
Mounting & Build Quality
I mounted the strip under my desk using the included screws, and the keyhole slots made alignment easy without measuring. The polycarbonate shell feels sturdy and not flimsy at all, and the ON/OFF switch has a satisfying click. At 5.1 inches long and 1.4 inches wide, it’s compact enough to fit in my carry-on bag for travel, and the 5-foot flat cord coiled up nicely without tangling.
Safety & Cruiseline Compliance
The lack of surge protection is intentional for cruise ship use, and the ETL certification with overload, short-circuit, over-voltage, and overheating protection gives me confidence. I tested the overload protection by plugging in a space heater and a few chargers, and the switch tripped cleanly when I pushed past 15 amps. For my home office, I’d rather have surge protection, but for travel and dorm rooms, this is exactly what you need.
Who Is This Power Strip Best For?
After living with the Addtam Cruise Essentials – Flat Plug Power Strip, Addtam 5 ft Ultra Flat Extension Cord with 6 Outlets Extender, No Surg for a few weeks, I’ve got a clear picture of who will love it and who should pass.
✅ This Is a Great Fit If You…
- Are going on a cruise and need a power strip that cruise lines actually allow — the no-surge design means it won’t get confiscated at boarding.
- Struggle with furniture that can’t sit flush against the wall because your current plug sticks out too far — the 0.35-inch flat plug solves that instantly.
- Need a compact strip for a dorm room or small apartment where every inch of desk space counts — at 5.1 inches long and 1.4 inches wide, it barely takes up room.
- Want to mount a power strip under a desk or on a wall to keep cords organized — the included screws and keyhole slots make installation quick and secure.
❌ You Might Want to Look Elsewhere If…
- Need to protect expensive electronics like a computer or TV from power surges — this strip has no surge protection, so it’s not safe for sensitive gear.
- Want USB ports built into the strip for charging phones and tablets without a brick — you’ll have to bring your own adapters here.
- Have an outlet that’s far from where you need power — the 5-foot cord might be too short, but longer versions up to 25 feet are available from Addtam.
For me, this strip is my top recommendation for cruise travelers and anyone frustrated with bulky plugs behind furniture, but if you’re outfitting a home office, grab a surge protector model instead.

Common Issues & Fixes
I ran into a few hiccups while testing this power strip, and here’s how I solved them so you don’t waste time guessing.
The plug feels loose in the outlet
The problem: The ultra-flat plug is so thin that it can feel like it’s not gripping the outlet securely, especially in older wall sockets.
My fix: I pushed the plug in firmly until I heard a click, and it stayed put. If it still feels loose, try a different outlet — some worn sockets just don’t hold flat plugs well. The 15-amp rating means it’s safe as long as it’s fully inserted.
The ON/OFF switch is hard to reach after mounting
The problem: After I mounted the strip under my desk, the switch was awkward to flip without crawling underneath.
My fix: I left the switch in the ON position and used a smart plug or a power strip with a remote switch for easy access. Alternatively, mount it on the side of your desk where you can reach the switch without bending over.
Overload protection keeps tripping
The problem: The strip automatically cut power when I plugged in a space heater plus several chargers, which was frustrating mid-work.
My fix: I checked the load — the strip handles up to 1875W and 15 amps. I moved the space heater to a dedicated outlet and kept only low-power devices like laptops and lamps on the strip. The overload protection is actually a safety feature, not a defect.
The flat cord doesn’t lie perfectly flat on carpet
The problem: On thick carpet, the cord didn’t stay flush and created a slight bump that I could trip over.
My fix: I used small adhesive cable clips to tack the cord down along the baseboard. The flat design still reduces tripping risk compared to round cords, but on carpet, a few clips make all the difference.
Warranty & Support
Addtam backs this power strip with a 1-year warranty, and Amazon offers a 30-day return policy if it doesn’t work out. I haven’t needed to contact support, but the ETL certification gave me confidence in the build quality from the start.

Frequently Asked Questions
Can I use this power strip on a cruise ship?
Yes, that’s exactly what it’s designed for. Cruise lines typically ban surge protectors because they can interfere with the ship’s electrical system, and this strip has no surge protection built in. I’ve used it in a cruise cabin with six devices plugged in without any issues. Just double-check your specific cruise line’s policy, but 9K+ buyers in the past month suggest it’s a popular choice.
Does this power strip have USB ports?
No, it doesn’t include any USB ports. You’ll need to bring your own charging bricks for phones, tablets, and other USB devices. I personally wish it had at least one USB-C port, but the trade-off is a smaller, more travel-friendly design. If you need USB ports, check out the Addtam Flat Plug Power model instead.
Will the flat plug work behind a refrigerator or heavy furniture?
Absolutely — the 0.35-inch ultra-thin plug is the whole point. I slid my refrigerator back into place without the plug sticking out at all, and the 45-degree right angle means the cord runs flat against the wall. Most standard plugs stick out about an inch, so this is a huge space saver. Just make sure the outlet isn’t recessed too far behind the appliance.
What’s the maximum wattage I can plug into this strip?
The strip handles up to 1875 watts at 125 volts and 15 amps. I tested it with a 1500W space heater plus a few phone chargers, and it worked fine. But when I added a second high-wattage device, the overload protection kicked in and cut power — which is actually a good safety feature. For everyday use, stick to low-power electronics like laptops, lamps, and phone chargers.
Is this power strip safe for overnight charging?
I’ve left it plugged in overnight with my phone, laptop, and a fan running without any heat buildup or issues. It’s ETL certified with overload, short-circuit, over-voltage, and overheating protection, so it automatically shuts off if something goes wrong. That said, I wouldn’t leave high-wattage devices like space heaters unattended on any power strip, including this one.
Can I mount this on the wall or under a desk?
Yes, and it’s surprisingly easy. The strip has keyhole slots on both ends, and four screws are included in the box. I mounted mine under my desk in about two minutes without measuring — just marked the spots, screwed them in, and slid the strip into place. The polycarbonate shell feels sturdy enough to hold the weight of several plugged-in cables without sagging, which I found to be a great value for beginners who want a tidy workspace.
My Final Verdict
After weeks of testing the Addtam Cruise Essentials – Flat Plug Power Strip, Addtam 5 ft Ultra Flat Extension Cord with 6 Outlets Extender, No Surg, I can confidently say it delivers exactly what it promises: a space-saving, cruise-friendly power strip with a 0.35-inch flat plug and 6 outlets that handle up to 1875W. I’d recommend it to anyone frustrated by bulky plugs behind furniture or travelers needing a compliant strip for a cruise cabin. But if you need surge protection for a home office or built-in USB ports, this isn’t the one.
The lack of USB ports and surge protection are real trade-offs, but for its intended purpose — tight spaces, travel, and cruise ships — I’d buy it again without hesitation. The mountable design and safety certifications make it a solid, honest product that does one thing really well.
