I was tired of my bulky power strip sticking out from behind the couch and blocking access to other outlets. That’s why I tested the Addtam Flat Plug Power Strip, Ultra Thin Flat Extension Cord – Addtam 12 Outlet 3 Sides Multiple Outlets, 5Ft, 1050J Surge — its 0.35-inch flat plug actually sits flush against the wall.
This 12-outlet strip is perfect for dorm rooms or crowded desks where every inch of space counts. The three-sided design with wide spacing handles bulky adapters without blocking neighboring plugs, though the 5-foot cord might feel short for larger rooms. Let me show you what worked and what didn’t.

What Stands Out — Key Features
- Ultra-Thin Flat Plug: The plug is only 0.35 inches thick, so it sits flush against the wall. I could slide my bed frame right up against it without any gap.
- 3-Side Outlet Layout: 12 outlets arranged on three sides with wide spacing. I plugged in three bulky laptop chargers without any of them blocking the others.
- 1050J Surge Protection: It guards against basic power spikes with 1050 joules of protection. That’s enough for my computer and phone, but not for a whole home theater setup.
- Wall-Mountable Design: Screw holes on both ends let you mount it to a desk or wall — screws included. I attached mine under my standing desk and it stays put.
- On/Off Switch with Safety: The switch automatically shuts off if power exceeds the 15-amp rating. I appreciate the peace of mind when I leave the house.
- Pure Copper Cord: The 5-foot extension cord uses pure copper for better current carrying capacity up to 15 amps. It feels flexible but not flimsy.
- Lightweight and Portable: At just 123 grams (about 4.3 ounces), it’s easy to toss in a bag for travel. I brought mine on a work trip without a second thought.

Pros & Cons — The Honest Take
✅ What I Like
- The 0.35-inch flat plug actually disappears behind my couch — no more gap or ugly protrusion.
- 12 outlets on three sides with wide spacing let me plug in three bulky laptop bricks without blocking any ports.
- Wall-mount design with included screws made it easy to attach under my desk and keep the desktop tidy.
- At only 123 grams, it’s light enough to toss in my travel bag for hotel rooms.
- The 1050J surge protection and auto shut-off switch give me confidence my devices are safe from minor spikes.
❌ What Could Be Better
- The 5-foot cord is short — I couldn’t reach an outlet across my living room without an extension cord.
- The 1050J surge rating is basic; it won’t protect expensive home theater gear from a big power surge.
- No USB ports included, so you’ll still need separate chargers for phones and tablets.
For the price, the flat plug and wide-spaced outlets make this a steal for dorm rooms or small desks — just know the short cord and basic surge protection keep it from being a whole-house solution.
⚖️ How Does It Compare?
I picked the One Beat 10Ft Extension and the Addtam Cruise Essentials as the closest alternatives because they solve similar problems — one offers a much longer cord, and the other adds USB ports for travelers. Here’s how they stack up against the Addtam Flat Plug Power Strip.

🔵 Alternative 1: One Beat 10Ft Extension
Best for: Anyone who needs to reach an outlet across a large room or behind tall furniture.
Key specs: 10-foot flat cord, 8 outlets, 3 USB ports, 1625W capacity, 125V
Where it beats the main product: The 10-foot cord is double the length of the Addtam’s 5 feet, so I can actually tuck it behind a bookshelf across the room.
Where it falls short: It only has 8 outlets compared to the Addtam’s 12, and the plug isn’t quite as thin at 0.5 inches.

- 【6 IN 1 Power Strip Extension Cord】- 3-side power strip with 6 AC outlets can accept the...
- 【Cruise Accessories Must Haves 】- The small cruise power strip comes with No surge protection...
⚪ Alternative 2: Addtam Cruise Essentials
Best for: Frequent travelers who need a compact strip with USB-C and USB-A ports for hotel rooms.
Key specs: 3 USB-C ports, 3 USB-A ports, 3 AC outlets, 5-foot cord, 125V
Where it beats the main product: It has 6 total USB ports including USB-C, so I can charge my phone, tablet, and laptop without carrying any wall adapters.
Where it falls short: Only 3 AC outlets versus the Addtam’s 12, so it’s useless for powering multiple desktop devices at once.
If you need to reach a faraway outlet, I’d grab the One Beat 10Ft Extension for its longer cord and USB ports — even though you lose 4 outlets. For travel, the Addtam Cruise Essentials is lighter and charges devices directly via USB-C, but you’ll only get 3 AC plugs. The original Addtam Flat Plug wins for desk or dorm setups where you need all 12 outlets and that ultra-thin 0.35-inch plug.
How It Actually Performs
Flat Plug Fit & Cord Reach
I was skeptical that a 0.35-inch plug could really sit flush against the wall, but it does. I slid my bed frame right over it with zero gap — no more crushing a bulky plug or leaving a two-inch gap behind furniture. The 5-foot pure copper cord is flexible enough to route along baseboards, but I wish it were longer for rooms where the outlet is across the room. It handled the full 15-amp rating without any warmth in the cord during my tests.
Outlet Spacing & Device Fit
The three-sided layout with wide spacing is a lifesaver for bulky adapters. I plugged in three laptop power bricks — one on each side — and none of them blocked another port. The 12 outlets let me charge my phone, tablet, monitor, desk lamp, and printer all at once without a single converter. My only nitpick is that the spacing on the short sides is slightly tighter, so very wide “wall wart” adapters might still touch if you cram them together.
Surge Protection & Safety Features
The 1050-joule surge rating is enough for everyday electronics like my computer and TV, but I wouldn’t trust it for a whole home theater setup with expensive receivers. The overload protection kicked in during a test when I deliberately exceeded 15 amps — the switch tripped automatically and I just flipped it back after unplugging a device. The ETL certification and UL-listed components gave me confidence, though the 1-year manufacturer warranty feels short compared to some competitors offering 3 years.
Mounting & Portability
I mounted it under my standing desk using the included screws, and the fixation design on both ends kept it rock-solid even when I bumped it with my knee. At only 123 grams, it’s light enough to toss in my backpack for a weekend trip. The compact flat shape slid easily into a suitcase pocket, though I miss having USB ports for travel — I still need separate chargers for my phone and tablet.
Who Is This Power Strip Best For?
After living with the Addtam Flat Plug Power Strip, Ultra Thin Flat Extension Cord – Addtam 12 Outlet 3 Sides Multiple Outlets, 5Ft, 1050J Surge for a few weeks, I’ve got a clear picture of who it really works for and who should keep shopping.
✅ This Is a Great Fit If You…
- Need to hide a power strip behind furniture — the 0.35-inch flat plug lets you push your couch, bed, or fridge right against the wall without any gap.
- Have a desk or dorm room with multiple bulky laptop adapters — the three-sided layout with wide spacing lets me plug in three power bricks without blocking any of the 12 outlets.
- Want to mount a strip under your desk or on a wall — the included screws and fixation design on both ends made installation easy and secure.
- Travel occasionally and need a lightweight option — at only 123 grams, it’s easy to pack in a carry-on for hotel rooms.
❌ You Might Want to Look Elsewhere If…
- Your outlet is far from where you need power — the 5-foot cord is short, and you’ll need an extension cord for larger rooms.
- You need to protect expensive home theater gear — the 1050-joule surge rating is basic and won’t handle major power spikes.
- You want to charge phones and tablets without carrying adapters — there are no USB ports on this strip, so you’ll need separate chargers.
If you’re a student, remote worker, or anyone with a cramped desk who needs maximum outlets from a strip that disappears behind furniture, this is my top pick — just be ready for that short cord.

Common Issues & Fixes
I ran into a few hiccups while testing this strip, and a couple of simple tricks made all the difference. Here’s what I learned so you don’t have to figure it out yourself.
The Plug Won’t Stay Flush Against the Wall
The problem: The 0.35-inch flat plug kept popping out slightly because my wall outlet was recessed too deep.
My fix: I pushed the plug in firmly at a slight angle — straight in first, then tilt it toward the wall. If your outlet is really recessed, a small plastic outlet spacer from any hardware store gives the plug enough grip to stay flush.
The Strip Wobbles When Mounted Under a Desk
The problem: After screwing it to the underside of my desk, the strip wobbled because I only used one screw on each end.
My fix: I tightened both screws fully, then added a small piece of double-sided mounting tape along the back edge. The tape stops the wobble without damaging the desk, and the strip stays rock-solid even when I plug and unplug devices.
Overload Switch Trips With Too Many Devices
The problem: I plugged in a space heater plus a few electronics, and the 15-amp overload protection shut everything off.
My fix: I unplugged the space heater and reset the switch on the side. The strip can handle 15 amps total, so I now keep high-draw appliances like heaters or air conditioners on a separate outlet. The automatic shutoff is a good safety feature, not a defect.
The Light Indicator Stays On Even When Devices Are Off
The problem: The built-in light indicator glows constantly when the strip is powered on, which bugged me in my bedroom at night.
My fix: I flipped the on/off switch on the side to kill power completely when not in use. Alternatively, I placed the strip behind a nightstand so the light isn’t visible from bed. It’s a minor annoyance, but the switch makes it easy to manage.
Warranty & Support
The Addtam Flat Plug Power Strip comes with a 1-year manufacturer warranty, which is shorter than some competitors offering 2-3 years. If you have an issue, Amazon’s 30-day return policy covers the return shipping. I’d recommend contacting Addtam directly through their Amazon seller page for faster support — they responded to my query within 24 hours.

Frequently Asked Questions
Can I plug this power strip into a surge protector?
Technically yes, but I wouldn’t recommend it. The strip itself has 1050 joules of surge protection, so plugging it into another surge protector can cause “series protection” issues where both devices fight each other. I tested it and the overload switch tripped more easily. Stick to plugging it directly into a wall outlet for best results.
How many devices can I actually charge at once?
All 12 outlets work simultaneously as long as you stay under the 15-amp limit. I charged my laptop (2 amps), phone (1 amp), monitor (1.5 amps), desk lamp (0.5 amps), and printer (0.5 amps) all at once without any issues. Just don’t plug in high-draw appliances like space heaters or air conditioners — those will trip the overload protection fast.
Does the flat plug work with all wall outlets?
It works with standard North American Type B outlets (the three-prong kind). I tested it on four different outlets in my apartment, and it sat flush on three of them. The one exception was a very old, recessed outlet where the plug couldn’t grip properly. For those cases, I used a small outlet spacer from the hardware store and it worked fine.
I found it great value for beginners who just need a simple, no-fuss power strip for their desk or nightstand.
Is the 5-foot cord long enough for most setups?
Honestly, it depends on your room. In my small home office where the outlet is right behind the desk, 5 feet was plenty. But in my living room where the outlet is across the wall, I had to use an extension cord. If your outlet is more than 4-5 feet from where you need power, consider the 10-foot or 15-foot versions available on Amazon.
Does it have USB ports for charging phones?
No, this specific model does not include any USB ports. That was a bit disappointing for me since I like to charge my phone directly from the strip without a wall adapter. If USB charging is important to you, check out the Addtam Cruise Essentials model instead, which has 6 USB ports including USB-C.
How do I reset the overload protection?
When the strip detects more than 15 amps of current, the on/off switch automatically flips to the off position. To reset it, unplug the device that caused the overload, wait about 10 seconds, then flip the switch back on. I accidentally triggered it with a space heater, and the reset took less than 30 seconds total.
My Final Verdict
After weeks of daily use, the Addtam Flat Plug Power Strip with 12 outlets and 1050 joules of surge protection has earned a permanent spot under my desk. The 0.35-inch flat plug genuinely disappears behind furniture, and the three-sided layout with wide spacing handles every bulky adapter I own without blocking ports. I’d recommend it to anyone with a cramped desk or dorm room who needs maximum outlets in a tight space — but skip it if you need a long cord or USB ports.
The 5-foot cord is the biggest trade-off, and the lack of USB ports means I still carry separate chargers for my phone. But for the price, the sheer number of outlets and the flush-fit plug make this a no-brainer for anyone who hates seeing a bulky power strip sticking out from behind their couch or bed.
