I’ve been wrestling with a mess of tangled cords behind my desk for months, so I picked up the TESSAN Flat Plug Extension Cord 5 FT, Surge Protector Power Strip with 4 AC Outlets 1 USB C and 2 USB A Ports to clean things up. Its 0.31-inch flat head fits perfectly behind my nightstand without sticking out like a sore thumb.
This little 7-in-1 strip is really for anyone who needs to charge a laptop, phone, and tablet in one spot without a bulky brick blocking neighboring outlets. I do wish the USB-C port pushed more than 15W total across all three USB ports β charging slows way down if you plug in everything at once. Still, the 900 joule surge protection gives me peace of mind for my gear.

What Stands Out β Key Features
- Flat Right-Angle Plug: The 0.31-inch slim flat head and 45-degree angle let me push this strip flush against the wall, freeing up the second outlet for a bulky charger.
- 7-in-1 Charging Hub: I can plug in my laptop, fan, phone, and tablet all at once β 4 AC outlets plus 1 USB-C and 2 USB-A ports cover everything.
- 900 Joule Surge Protection: The built-in short-circuit and over-current protection keeps my electronics safe from power spikes, which I really appreciate in my old apartment.
- Mountable Design: Two holes on the bottom let me screw this onto my desk leg, and the 4 rubber feet keep it from sliding around on my nightstand.
- USB-C Port Included: The 15W USB-C charges my phone decently fast, but I noticed the manual warns not to use all three USB ports at once or speeds drop significantly.
- Sturdy Polycarbonate Build: The casing feels solid and heat-resistant, not flimsy like some cheap strips I’ve owned before.
- Compact 3.8 x 2-Inch Footprint: It takes up almost no space on my desk, leaving room for my coffee mug and notebook.

Pros & Cons β The Honest Take
β What I Like
- The flat 0.31-inch plug sits flush against the wall, so I can still use the second outlet on my wall plate.
- Four AC outlets handle my laptop, monitor, and fan all at once without any power drop.
- The 900 joule surge protection gives me real peace of mind for my expensive electronics.
- Rubber feet keep the strip planted on my desk, and the polycarbonate build feels tough.
- Mounting holes on the bottom let me screw it under my desk for a clean, hidden setup.
β What Could Be Better
- Total USB output is only 15W β charging my phone and tablet together slows to a crawl.
- The USB-C port doesn’t support fast charging for newer laptops, so I still need a separate brick.
- The 5-foot cord is short for larger rooms; I wish it came in a 10-foot version without paying more.
For daily use on a desk or nightstand, the pros easily win β that flat plug and solid build are hard to beat. Just don’t expect the USB ports to charge multiple devices quickly, and you’ll be happy.
βοΈ How Does It Compare?
I lined up the TESSAN against two other popular surge protectors I’ve used to see how it really stacks up for different needs. Both the Addtam and HANYCONY models are solid contenders, but each has a distinct trade-off worth knowing about.

π΅ Alternative 1: Addtam Surge Protector
Best for: People who need more AC outlets and don’t mind a bulkier plug.
Key specs: 8 AC outlets, 2 USB-A ports, 1080 joules surge protection, built-in nightlight
Where it beats the main product: It offers double the AC outlets and 180 more joules of protection for a similar price.
Where it falls short: The plug is a standard right-angle design that doesn’t sit as flush against the wall as the TESSAN’s 0.31-inch flat head.

βͺ Alternative 2: HANYCONY Surge Protector
Best for: Travelers who need a compact strip with multiple USB-C ports.
Key specs: 3 AC outlets, 2 USB-C ports, 2 USB-A ports, 1080 joules protection, 5-foot cord
Where it beats the main product: It has two USB-C ports instead of one, which is great for charging a phone and earbuds at the same time.
Where it falls short: It only has 3 AC outlets compared to the TESSAN’s 4, and the total USB output is still limited to 15W like the TESSAN.
If you need more than 4 AC outlets for a home office setup, the Addtam is a better bet with its 8 outlets and higher 1080 joule rating. But for tight spaces behind furniture, the TESSAN’s flat plug is unbeatable, and I’d pick it over the HANYCONY for the extra outlet alone. The HANYCONY only wins if you absolutely need that second USB-C port for travel.
How It Actually Performs
AC Outlet Power Delivery
I plugged a 1250W space heater into one outlet, my laptop charger into another, and a desk lamp into a third β all ran without tripping the strip. The 10 amp, 125 volt rating held up fine under that load, and the polycarbonate casing stayed cool to the touch after an hour. I was honestly surprised how well it handled near-max power without any buzzing or heat buildup.
USB Charging Speed
Here’s the disappointing part. I tested the 15W USB-C port with my phone and got a slow 5W charge β nowhere near fast charging. When I plugged all three USB ports into devices, the manual’s warning proved true: speeds dropped so much my tablet barely gained 10% in an hour. For a single device, it’s fine, but don’t expect to charge three things at once.
Flat Plug and Cord Flexibility
The 0.31-inch flat head is the star of the show. I wedged it behind my bed frame where my old standard plug wouldn’t fit, and the 45-degree angle left the second wall outlet completely free. The 5-foot cord is long enough for a nightstand or desk but too short for running behind a large couch β I’d grab the 10-foot version for that.
Build Quality and Mounting
The polycarbonate shell feels dense and durable, not like the flimsy plastic on cheaper strips. I screwed it under my desk using the two mounting holes, and the four rubber feet keep it planted on my nightstand without sliding. After a month of daily use, there’s no wobble in the outlets and the USB ports still feel tight when plugging in cables.
Who Is This Power Strip Best For?
After using the TESSAN Flat Plug Extension Cord 5 FT, Surge Protector Power Strip with 4 AC Outlets 1 USB C and 2 USB A Ports for a month, I have a clear picture of who will love it and who should keep shopping. Here’s my honest breakdown.
β This Is a Great Fit If You…
- Need a slim plug that fits behind furniture β the 0.31-inch flat head let me slide it behind my bed frame without crushing the cord.
- Want a compact desktop strip for a laptop, phone, and lamp β 4 AC outlets and 3 USB ports handle all three without taking up much space.
- Prefer mounting your strip under a desk or on a wall β the two mounting holes made it easy to screw this out of sight.
- Only need to charge one USB device at a time β the single USB-C port works fine for a phone, just don’t expect fast charging speeds.
β You Might Want to Look Elsewhere If…
- Plan to charge three USB devices at once β the 15W total output slows everything to a crawl, just as the manual warns.
- Need a long cord for a large room β the 5-foot length barely reaches behind my desk; consider the 10 or 15-foot versions.
- Want fast USB-C charging for a laptop β this strip caps at 15W, so you’ll still need your original power brick for any modern laptop.
If you’re someone who needs a low-profile strip for a nightstand or small desk and mostly charges one device at a time, this is my top pick. For heavy multi-device USB charging, I’d point you toward a model with higher wattage ports.

Common Issues & Fixes
After a month with this TESSAN strip, I ran into a few hiccups and figured out simple workarounds. Here’s what to watch for and how I solved each problem.
USB Charging Slows to a Crawl
The problem: Plugging my phone, tablet, and earbuds into all three USB ports at once barely charges anything β the 15W total output gets split too thin.
My fix: I now charge only one USB device at a time, or use the AC outlets for a wall brick. The manual warns against multi-port charging, and it’s right β stick to one device for reasonable speed.
5-Foot Cord Isn’t Long Enough
The problem: The cord barely reaches from my wall outlet behind the bed to my nightstand, leaving no slack for adjustments.
My fix: I picked up the 10-foot version of this same strip for the bedroom and moved the 5-footer to my desk where outlets are closer. Check the available sizes before buying.
Strip Slides on Smooth Surfaces
The problem: On my glass desk, the rubber feet don’t grip well and the strip shifts when I unplug a heavy laptop charger.
My fix: I used the two mounting holes to screw it under my desk β problem solved. For a nightstand, the rubber feet work fine on wood or fabric surfaces.
Surge Protection Indicator Not Visible
The problem: There’s no obvious light or indicator showing whether the 900 joule surge protection is still active after a power spike.
My fix: I just assume it’s working and test it every few months by plugging in a lamp and flipping the breaker. If the strip stops protecting, I’ll replace it β cheap insurance for my gear.
Warranty & Support
TESSAN offers a 30-day return guarantee through Amazon, and the polycarbonate build feels sturdy enough to last years. For warranty claims, you’ll need to contact the manufacturer directly through their Amazon store page β there’s no phone number, but email support responded to me within two business days. Keep your order receipt handy.

Frequently Asked Questions
Does the TESSAN flat plug work with older two-prong outlets?
No, this strip uses a Type B 3-pin plug with a grounding prong, so it won’t fit into older two-prong outlets without an adapter. I tested it in my apartment’s newer three-prong outlets, and the 0.31-inch flat head sits perfectly flush. If you have old wiring, you’ll need a grounding adapter or a different strip.
Can I charge my laptop through the USB-C port?
Technically yes, but don’t expect much. The USB-C port maxes out at 15W total across all three USB ports, which is nowhere near enough for a modern laptop that needs 45W to 100W. I tried charging my work laptop and it barely held the battery level β you’re better off using one of the 4 AC outlets with your original charger.
How many devices can I plug in at once without issues?
You can plug in up to 7 devices total β 4 through the AC outlets and 3 through the USB ports. But here’s the catch: the manual clearly states not to charge multiple USB devices at the same time because the 15W output gets split and slows to a crawl. I run my laptop, monitor, and fan from the AC outlets and charge just my phone via USB, and everything works fine.
Is the 900 joule surge protection enough for expensive electronics?
For basic protection on a desk or nightstand, 900 joules is decent for things like a lamp, phone charger, or small fan. But for a high-end gaming PC or home theater equipment, I’d want at least 2000 joules. I use this strip for my work laptop and peripherals, and I feel safe enough β it’s great value for beginners who just need basic protection without spending a fortune.
Can I mount this strip on the wall or under a desk?
Yes, absolutely β that’s one of my favorite features. The bottom has two mounting holes, so I screwed it under my desk in about five minutes. The 4 rubber feet also keep it from sliding on a nightstand or desk, so you have both options depending on your setup.
Does the flat plug block the second wall outlet?
Not at all β that’s the whole point of the 45-degree right angle design. The 0.31-inch flat head sits so low against the wall that I can still use the second outlet on my duplex wall plate for a separate plug. This was the main reason I bought it, and it delivered exactly as promised.
My Final Verdict
After a month of daily use, the TESSAN Flat Plug Extension Cord 5 FT has earned a permanent spot on my desk. The 0.31-inch flat head frees up the second wall outlet, the 4 AC outlets handle my laptop and monitor without issue, and the 900 joule surge protection gives me basic peace of mind. I’d recommend it to anyone with tight outlet spacing who only needs to charge one USB device at a time β but if you need fast multi-device USB charging, look elsewhere.
The 15W USB limit is frustrating, but honestly, I just use the AC outlets for my laptop brick and save the USB port for my phone. For the space-saving design alone, I’d buy it again without hesitation.
Ready to Check the Price?
If you need a slim, mountable power strip for a desk or nightstand and don’t mind the USB limitations, this TESSAN is a solid choice worth a look.
