Your wall outlets are lying to you. A standard duplex outlet gives you two spots, but your devices need five — and that's before you count USB chargers. Enter the wall outlet extender: a compact device that turns one outlet into a multi-port power station. Two of the most popular options are the Addtam Surge Protector Outlet Extender and the Belkin 6-Outlet Surge Protector.
One costs $12.99. The other costs $29.99. One has USB-C in 2026. The other doesn't. The choice seems obvious — but let's dig into the details to make sure.
Quick Verdict
Buy the Addtam Surge Protector Outlet Extender if: You want more ports per dollar, USB-C fast charging, a built-in night light, and a rotating plug that actually fits behind furniture. At $12.99, it's the smartest outlet upgrade you can buy — and it leaves your second outlet fully usable.
Buy the Belkin if: You need the connected equipment warranty for peace of mind, prefer a traditional power strip layout, or need 1000+ Joules of surge protection for expensive home theater gear. The Belkin is well-built, but it's a corded power strip taking up space on your floor or desk.
Our pick: The Addtam Surge Protector Outlet Extender. More features, less money, better form factor. It's not close.
Our Pick 🏆 Addtam Surge Protector Outlet Extender
$12.99 on Amazon
The Addtam Surge Protector Outlet Extender has quietly become one of the most popular wall outlet extenders on Amazon, and for good reason — it solves almost every complaint people have about power strips.
The USB-C port is the headline feature. While Belkin still uses two USB-A ports (increasingly obsolete in 2026), Addtam includes a proper USB-C fast-charge port that handles phones, tablets, and even the latest laptops at full speed. No more hunting for a charging brick.
The 45° rotating plug means it doesn't block the second outlet on your duplex. This is huge — most competitors force you to sacrifice an entire outlet. Addtam leaves the lower outlet fully usable. The built-in night light is a soft LED that's bright enough to find in the dark but dim enough not to disturb sleep.
Key specs: 5 AC outlets (3 front + 2 side), 3 USB ports (2 USB-A + 1 USB-C 3.0A), 800 Joules surge protection, rotating 45° low-profile plug, LED night light, 5.6 oz.

⚡ Belkin 6-Outlet Surge Protector
$29.99 on Amazon
Belkin has been making surge protectors since the 1990s, and their reputation for quality is well-earned. The Belkin 6-Outlet Surge Protector is a solid, traditional power strip with excellent build quality and a connected equipment warranty that covers up to $300,000 in damages.
The 6 outlets are all spaced widely enough to fit bulky transformer plugs — a pet peeve of power strip users. The 1000 Joule rating technically exceeds the Addtam's 800 Joules, which matters if you're protecting expensive electronics.
But in the wall-mounted outlet extender space, Belkin is playing catch-up. No USB-C, no night light, no rotating plug. It's a traditional corded power strip that takes up desk or floor space. At $29.99, it's expensive for what it offers in 2026.
Key specs: 6 AC outlets, 2 USB-A ports (shared 2.4A), up to 1000 Joules surge protection, 3-6 ft cord, $300K connected equipment warranty.

Why the Addtam Wins
USB-C in 2026. This is the biggest gap. Belkin's two USB-A ports are effectively obsolete for fast charging. The Addtam's USB-C port charges modern phones and tablets at full speed. If you're buying a new power accessory in 2026, USB-C is table stakes.
Wall-mount form factor. The Addtam mounts flush to the wall with a rotating plug that doesn't block the second outlet. No cord, no clutter, no tripping hazards. The Belkin is a traditional corded strip — it takes up desk or floor space and adds visual clutter.
57% cheaper. $12.99 vs $29.99. The Addtam costs less than half and offers more features. The value gap is striking.
Night light. A simple feature that costs pennies to add, yet Belkin doesn't offer it. The soft LED is genuinely useful for finding the outlet in the dark without turning on overhead lights.
"At $12.99, the Addtam is the smartest outlet upgrade you can buy. It's cheaper, includes USB-C, adds a useful night light, and mounts flush to the wall."
Where the Belkin Excels
Connected equipment warranty. Belkin backs their surge protectors with up to $300,000 in connected equipment coverage. If a surge damages your gear, Belkin will cover the repair or replacement. That's real peace of mind for expensive electronics.
Higher Joule rating. 1000 Joules vs 800 Joules. For most household electronics, 800 Joules is sufficient — it'll handle a typical lightning surge or power fluctuation. But if you're protecting a home theater or server rack, the extra headroom matters.
Wide outlet spacing. The Belkin's 6 outlets are spaced widely enough to accommodate bulky transformer plugs. The Addtam's side outlets are more limited in this regard.
Who Should Buy Which
✅ Buy Addtam if you...
- Need USB-C charging for modern devices
- Want a clean, wall-mount setup without cords
- Like the idea of a built-in night light
- Want to maximize value per dollar
- Need to keep the second outlet usable
✅ Buy Belkin if you...
- Need 1000+ Joules for expensive equipment
- The connected equipment warranty gives you peace of mind
- Prefer a traditional power strip layout
- Need extra-wide spacing for transformer plugs
The Bottom Line
Our Take
The Addtam Surge Protector Outlet Extender is simply the better product for 90% of users. It's cheaper, includes USB-C (which Belkin bizarrely omits in 2026), adds a useful night light, and mounts flush to the wall without blocking your second outlet.
The Belkin is well-built and carries a strong warranty. But at $12.99 vs $29.99, the Addtam delivers more features for 57% less. The math is straightforward.
