Addtam Surge Protector Outlet Extender, 6-Outlet Splitter with 4 USB Wall Charger(2 USB-C Ports), Multi Plug Wall Outlet 1800J Power Strip for Home Office Dorm Room Essentials

A compact way to modernize a single outlet

My home office and bathroom both suffer from the same problem: a single duplex outlet doing the work of six. The Addtam outlet extender has been an easy, tidy upgrade—turning one wall receptacle into six grounded AC outlets plus four USB ports without adding a tangle of cables or a floor‑bound power strip. After a few weeks of living with it in a couple of high‑traffic spots, I have a clear sense of where it shines and where it doesn’t.

Design and installation

This is a plug‑in wall tap designed primarily for a standard duplex receptacle. Setup is simple:

• Remove the faceplate’s center screw.
• Plug the extender into the outlet.
• Secure it with the included screw through the middle.
• A plastic stabilizing prong on the back helps keep things aligned.

If you skip the screw, the unit will still work, but it’s much easier to wiggle when unplugging stubborn cords. Mounted properly, it stays put and feels solid, which matters on a bathroom counter or a kitchen backsplash where you’re frequently swapping devices.

The six AC outlets are arranged with 2.2 inches of spacing, noticeably wider than most wall taps. That extra room makes a practical difference—I can fit two oversized power bricks side by side without blocking adjacent outlets. The housing is fire‑resistant ABS, the finish is clean, and the front LED provides a quick at‑a‑glance “protected” status.

It does protrude from the wall a couple of inches. That’s not unusual for this category, but if you’re placing it behind furniture or in a tight hallway, plan accordingly. On a counter or desktop wall, the depth is a non‑issue and arguably an advantage because large plugs have more clearance.

Compatibility note: it’s designed for standard duplex outlets with a center screw. It can physically work with many decorator/GFCI plates that still have a center screw, but the fit is best on a traditional duplex. If your receptacle doesn’t have the center screw, skip this style or be prepared for less-stable mounting.

Power and charging performance

The six AC outlets behave like a compact power strip you’ve mounted to your wall. I’ve used them for lamps, a label printer, a small speaker, an electric toothbrush base, and a laptop power adapter. Everything powered up cleanly, and I didn’t notice any flex or looseness in the sockets. As always, be mindful of the circuit’s total load—resist the temptation to run a space heater and a hair dryer alongside chargers on the same 15A circuit.

On the USB side, you get:

• Two USB‑A ports rated up to 5V/2.4A
• Two USB‑C ports rated up to 5V/3A

There’s smart negotiation for 5V devices, and for most phones, earbuds, game controllers, and e‑readers, charging is straightforward and reliable. The important caveat is that the USB‑C ports do not support higher‑voltage fast‑charge protocols (no USB‑C Power Delivery or Quick Charge). That means you’re capped at 5V; modern phones and tablets that can jump to 9V or higher will charge, but at slower 5V speeds. For overnight charging or desk duty, that’s fine. For a quick top‑up before running out the door, you’ll want a PD charger.

The restraint here is intentional: there’s no AC cord to manage, no brick, and no wall‑wart chargers—just a neat charging hub integrated into the tap. For a centralized charging station in the kitchen, dorm, or guest room, the simplicity makes sense.

Surge protection and safety

Surge protection isn’t all created equal, and this unit is better equipped than typical single‑MOV wall taps. Addtam uses a three‑stage setup (TVS, MOV, and GDT) rated at 1800 joules. In plain terms, that design can clamp down on transients more quickly and spread the work across multiple components, which is helpful for longevity and for dealing with nasty spikes.

A few safety‑minded notes I appreciate:

• ETL certification and a fire‑resistant (1382°F) ABS shell
• A protection indicator light; if it goes out, treat the unit as unprotected and replace it
• A rigid, screw‑mounted design that resists being yanked out of the wall

It’s still a wall tap, not a whole‑home solution. If you live in an area with frequent lightning or unreliable power, consider layering your protection with a quality UPS for critical gear. But for everyday surge protection at the outlet, this is well thought out for the price and form factor.

Day‑to‑day convenience

Two use cases stood out for me.

• Bathroom: The secure screw mount is a quiet hero here. Unplugging hair tools often tugs typical tap adapters loose. This one stays put. I can power an electric toothbrush base, water flosser, night light, and charge a razor—all without tying up the counter with a power strip.
• Home office: It’s a clean way to power a small desktop setup—monitor light, dock, label printer—while keeping two USB ports free for peripherals. I leave one USB‑C as a permanent cable for a phone and one USB‑A for a headset.

The wide outlet spacing is genuinely useful. It avoids the perennial problem of blocky chargers hogging space and turning “six outlets” into “three usable outlets.” The unit also runs cool to the touch in typical use, and the sockets have a positive feel when plugging and unplugging.

Limitations and trade‑offs

• No fast charging on USB‑C: The 5V/3A ports are fine for overnight or low‑demand charging. They won’t fast‑charge many modern phones or any USB‑C laptops that require PD. If you routinely need fast top‑ups, add a compact PD charger to one of the AC sockets.
• Duplex‑first fitment: It’s intended for duplex receptacles. It can work on decorator/GFCI styles that retain the center screw, but alignment and stability may vary.
• Wall clearance: It extends a bit from the wall. Not a problem on open walls, noticeable behind furniture.
• Circuit awareness: Like any multi‑tap, it’s easy to overdo it. Keep high‑draw appliances (heaters, hair dryers) separate from a fully loaded charging hub.

None of these are dealbreakers for me, but they’re worth understanding so you’re not surprised.

Who it’s for

• Households and dorms that need to convert a single outlet into a tidy multi‑device charging and power station
• Kitchens, bathrooms, and entry areas where a power strip would be messy or in the way
• RVs and small apartments with limited outlets
• Guest rooms, where a simple “everything in one place” charger is a hospitality upgrade

If your primary need is fast USB‑C charging for tablets and laptops, a dedicated PD charger should be part of your setup—this extender can host it nicely via one of the AC outlets.

The bottom line

The Addtam outlet extender strikes a smart balance: generous AC spacing, a useful set of USB ports, and a sturdier, safer design than many bargain wall taps. The three‑stage, 1800J surge protection and the secure screw mount are the standout features, translating to fewer annoyances and better protection in real‑world use. The trade‑off is clear—USB‑C ports limited to 5V and a bit of extra depth off the wall—but for an all‑in‑one, plug‑and‑go outlet upgrade, it’s an easy piece of kit to live with.

Recommendation: I recommend it. If you want to neatly multiply a duplex outlet while adding basic USB charging and meaningful surge protection, this is a dependable, space‑savvy choice. Pair it with a separate USB‑C PD charger if fast mobile or laptop charging is part of your daily routine, and you’ll have a flexible, clutter‑free setup that covers most household and office needs.
