SUPERDANNY Flat Extension Cord Surge Protector Power Strip Review

Eight Outlets and I Still Had Room to Spare

The moment I unboxed it, I was counting: eight AC outlets plus four USB ports, more charging real estate than anything else I’ve had on a nightstand. Most strips I’ve tested top out at six AC outlets and two USB-A ports, so hitting twelve total on something this slim stopped me mid-unbox. You can grab one through this link if you want to follow along.

The pitch is simple. It’s a flat extension cord that charges 12 devices at once and slips behind furniture without sticking out. I wanted to know if that actually holds up when you start loading it, or if it’s one of those strips that looks better on the box than on my nightstand.

What You Get on This Extension Cord Flat Plug

Eight AC outlets, four USB ports, zero crowding, this is what it delivers out of the box. The AC outlets sit four on the top and two on each side, which is how it hits eight. Then you’ve got two USB-A and two USB-C ports built in. There’s a power on switch right on the front so you can kill everything at once.

The end that goes into the wall is a flat outlet, only 0.3 inches thick with a 45° right angle. That’s the portion that goes behind furniture. It sits flush so you can shove the strip behind a sofa or bed without the plug bowing out. The cord runs 10 ft, and there are two mounting holes on the back if you want to screw it to a desk or wall.

Loading It Up With Real Devices

I plugged in four things at once and it didn’t blink. A thumb drive into a USB-A, then a lightning cable, then a USB-C into a phone, and finally another USB-A right into my iPhone. Everything lit up at the same time. That was the moment the “12 devices” claim stopped being marketing and started being my nightstand.

After all that, I still had seven other outlets I could plug into. That’s the part I keep coming back to. I charge just about all of my electronic devices off this one strip: my personal cell phone, my work cell phone, my iPods, whatever else needs juice. I plug it all in at night and I’m ready for my day. No hunting for a free wall socket in the morning.

The 1.65-inch spacing between AC outlets is the detail most strips skip and then you hate them for it: I had a bulky phone-charger block and a wide laptop brick plugged in side by side and neither one ate the outlet next to it, all eight stayed open. The white casing earns its keep too; sitting on a white nightstand it reads as furniture, not hardware.

The USB Ports Charge, But Don’t Expect Speed

The USB side is for topping off, not for fast charging. Total USB output caps at 15W across all four ports, with USB-A at 5V/2.4A and USB-C at 5V/3A. That’s fine for phones, earbuds, a smartwatch, or iPods sitting overnight. It is not going to blast a laptop or a big tablet back to full in an hour.

For me that’s a non-issue because I plug everything in before bed and it’s ready by morning. But if you’re the type who needs a phone from dead to full over a lunch break, you’ll want to run that phone off its own fast charger in one of the AC outlets instead of the built-in USB. Knowing that up front saves you from expecting more than the 15W can give.

Who This Extension Cord Flat Plug Fits Best

If you end every night playing musical outlets, unplugging a lamp to charge a phone, leaving a tablet dead because there’s nowhere to put it, this strip solves that in one move. I run a work phone, a personal phone, two iPods, and a USB-C earbud case off it simultaneously, and the strip still has ports free. That’s the actual problem it fixes.

Dorm rooms and apartments are the obvious fit. When you’ve got one or two wall outlets for a whole room, an 8-outlet strip that mounts to a desk and hides its flat plug behind the bed solves a real problem. Home office desks with a monitor, laptop, phone, and a couple of USB gadgets are the other sweet spot. The flexibility and portability are what I like most; I can move it wherever the pile-up is.

Flat Plug Strip vs. a Bulky Surge Protector

The flat plug is the reason to pick this over a standard surge protector. A normal strip has a fat plug that sticks out an inch or two from the wall, so you can never push furniture flush against it. This one’s 0.3-inch flat head sits nearly against the wall, and the 45° angle leaves the outlet below it free.

Where a bulkier tower surge protector wins is raw joule rating and outlet count for big home-theater setups. Those often push well past 1050 Joules and add coax or ethernet protection. If you’re guarding a TV, receiver, and game console stack, a heavy tower still makes sense. For charging phones, tablets, and laptops in a tight space, the flat design here is the smarter buy.

A Couple Things I’d Do at Setup

Decide where it’s living before you plug anything in. The flat plug is meant to go behind furniture, so route the 10 ft cord to your spot first, then mount it with the two rear holes if you want it fixed to a desk. Trying to reposition it after every port is full is a hassle.

Use the AC outlets for anything that needs speed and save the four USB ports for slow overnight top-offs. That way you’re not fighting the 15W USB cap. And flip that front power switch off when you’re away for a while; it kills all eight outlets at once, which is a nice simple safety habit.

Pros

• Eight AC outlets plus four USB ports, four devices plugged in with seven slots still free
• Flat 0.3-inch plug hides flush behind a sofa, bed, or nightstand
• 1.65-inch outlet spacing fits chunky wall-wart plugs without blocking neighbors
• White color blends into furniture instead of standing out
• Feels sturdy and durable, with a single power switch for everything

Cons

• USB output caps at 15W total, so it’s for overnight top-offs, not fast charging
• 10 ft cord is fixed length; no reach beyond that across a large room
• Eight outlets is overkill if you only ever charge one or two things

Frequently Asked Questions

Does it really fit behind a couch or bed?

Yes. The plug is only 0.3 inches thick with a 45° angle, so it sits nearly flush against the wall and lets you push furniture back over it. That flat head is the whole reason this hides where a normal plug can’t.

Can I charge a laptop and phone at the same time?

Yes, but run the laptop off an AC outlet, not the USB ports. There are eight AC outlets for full-size chargers and four USB ports for phones and small gadgets, so you can power both at once easily.

How fast are the USB-C ports?

The USB-C ports run 5V/3A and total USB output is capped at 15W across all four ports. That’s solid for overnight charging of phones, earbuds, and watches, but it’s not a fast-charging setup for power-hungry tablets.

Does it need an app or account to work?

No. It’s a plug-and-go power strip with no app, account, or firmware. You plug it into the wall, flip the switch, and start charging. Nothing to set up beyond deciding where it lives.

Is it safe to leave plugged in overnight?

Yes, that’s exactly how I use it. It has 1050 Joules of surge protection, 1250W overload protection, and a V-0 fire-retardant casing, so I plug everything in at night and it’s ready by morning without me worrying about it.

Can I mount it to a wall or desk?

Yes. There are two mounting holes on the back for screwing it to a wall, desk, or counter. Handy for a dorm or home office where you want it fixed in one spot instead of sliding around.

Will chunky wall plugs block the outlets next to them?

Not usually. There’s 1.65 inches of space between AC outlets to fit large plugs, and the outlets are spread across four sides. That layout keeps big wall-wart chargers from crowding out the outlets beside them.

Is 10 feet enough cord for a living room?

For most desks, beds, and behind-the-sofa runs, yes. The 10 ft flat cord reaches across a typical room to the nearest outlet. If you need to span a very large space to a distant wall socket, measure first because the length is fixed.

Does it work with older USB-A cables too?

Yes. It has two USB-A ports alongside the two USB-C, so your older lightning and micro-USB cables plug right in. I ran a lightning cable and a USB-C phone off it at the same time with no issue.
