Addtam Surge Protector Power Strip - 10 FT Extension Cord, Power Strip with 12 Widely AC Outlet 3 USB, Flat Plug, Wall Mount Overload Protection, 1050J, Desk Charging Station for Home Office, ETL Listed

Why this strip earned a permanent spot under my desk

I added the Addtam power strip to my home office to simplify a busy standing-desk setup—multiple monitors, a docking station, speakers, a lamp, and a rotating cast of gadgets that need power or a top-up. After a few weeks of daily use, it’s the first power strip I’ve used that truly fixes the two headaches that usually come with multi-outlet blocks: bulky “wall wart” adapters colliding with each other, and cords never reaching where you actually need them. Between the three-sided, widely spaced outlets and the 10-foot flat cord with a right-angle plug, this strip gets the physical design right—and that makes all the difference.

Design and build

This is a three-sided, 12-outlet power strip with three USB charging ports. The housing is compact for its capacity, and the “three sides” approach spreads outlets so large power bricks don’t stack on top of each other. On my desk, I used all 12 AC outlets with a mix of slim plugs and chunky adapters; nothing blocked, and I didn’t need adapters or short pigtail extenders.

The 10-foot cord is the sweet spot for flexibility without creating a coil of excess. The plug is flat and angled at 45 degrees, which helps it sit behind furniture and, on most wall outlets, keeps the second receptacle accessible. The overall build feels solid and, importantly, stays put when mounted or resting on a surface.

If you want to get the strip off the floor—and you should, for both cable management and dust reasons—there are keyhole slots for wall or underside mounting. Addtam includes screws, and the strip locks onto them securely once you get the spacing right.

Setup and mounting

Mounting under my desk took about five minutes:
- Measure and mark the keyhole spacing.
- Drive the included screws until the heads sit proud enough to slide the strip on.
- Seat the strip and tug gently to ensure it’s locked.

The result: the outlets now face out and up, which makes swapping devices quick without crawling under furniture. The long cord runs up the desk leg with a few cable clips, then tucks flat along the baseboard to the outlet. No snags, and nothing bulges out behind the desk.

Capacity and spacing in real use

This strip is rated 15A/1875W. That’s standard for a US 120V circuit and plenty for a typical workstation or entertainment center. I ran the following simultaneously without tripping the breaker or noticeably warming the housing:
- 27-inch monitor and ultrawide monitor
- Laptop dock with 100W external brick
- Desk lamp
- Powered speakers
- External storage dock
- Phone charger stand
- Label printer and photo printer (intermittent)

The three-sided design is the star here. I deliberately arranged a few oversized adapters to see if I could force a conflict. It took effort. Unless you’re using multiple unusually large transformer bricks, the spacing works as advertised.

USB charging: good for accessories, not a fast-charge replacement

You get three USB charging ports on the strip. They deliver standard 5V charging; in my testing, a single port provided a full-speed phone charge in line with 5V/2.4A expectations. When I connected multiple devices, the total current is shared across ports, so speeds drop accordingly. That’s normal for integrated strip chargers.

Practical takeaways:
- Great for phones, tablets, e-readers, headsets, and small accessories.
- Not for powering laptops or anything that requires USB-C Power Delivery or proprietary fast-charge protocols.
- Ideal as a convenience charger so you don’t burn an AC outlet on a charging brick.

If you rely on true fast charging for your phone or need to power a USB-C laptop from the strip, keep your dedicated charger in the mix.

Safety and surge protection

Surge protection is rated at 1050 joules. That’s a reasonable level for a home office, dorm, or bedroom setup—plenty for routers, monitors, and peripherals in areas with normal power quality. There’s also overload, short-circuit, overcurrent, over-voltage, and overheating protection built in, plus an on/off switch that doubles as a resettable circuit breaker. The unit is ETL listed, which is important; it indicates compliance with recognized safety standards.

A few context notes:
- Joule ratings describe how much surge energy a protector can absorb before it’s no longer protective. 1050J isn’t class-leading, but it’s enough for many use cases.
- If you’re protecting a pricey AV stack or a gaming PC in a storm-prone area, you might prefer a model with 2000J+ protection or a whole-home surge suppressor at the panel—this strip will still work, but it wouldn’t be my single point of defense.

Day-to-day experience

• Quiet operation: No coil whine or buzzing under load.
• Switch feel: The rocker switch is firm; it won’t shut off from an accidental brush.
• Heat: Even with most outlets populated, the housing stayed cool to the touch in my tests.
• Cable management: The long cord and right-angle plug reduce the need for an additional extension cord, which simplifies cable runs and cuts points of failure.

I also like how easy it is to reconfigure. Because the outlets wrap around three sides, I can keep always-on devices plugged into the back while reserving a “front” face for temporary gear like a soldering iron or test charger. It’s a small ergonomic win that makes the strip feel less cramped.

Where it falls short

No product hits every mark, and there are trade-offs here:
- Surge headroom: 1050J is fine for most setups, but heavy AV or high-end gaming rigs may warrant a higher rating.
- USB power: The three USB ports are convenience-grade 5V. There’s no Power Delivery for laptops or high-speed charging for flagship phones.
- No line-conditioning extras: You don’t get coax/Ethernet protection, and there’s no noise filtering spec published. That’s typical at this price and category, but worth noting if you need it.

None of these are deal-breakers for desk or dorm use—they’re just boundaries to keep in mind.

Who it’s for

• Home offices and standing desks that need many outlets, long reach, and clean cable routing.
• Students and renters who benefit from a wall-mountable strip that can live under a bed, behind a dresser, or on a wall without blocking neighboring plugs.
• Light AV setups or hobby benches where bulky adapters are common.

Who should look elsewhere:
- Users who need USB-C PD for laptop charging built into the strip.
- Those seeking the highest joule ratings or specialized surge protection for coax/ethernet.

Practical tips

• Mount it. Getting the strip off the floor prevents dust intake for power bricks and makes it easier to reset the switch if needed.
• Reserve a face for temporary tools. Keeping one side “open” reduces plug shuffling.
• Label your bricks. If you have many similar-looking adapters, a few small labels save time and mistakes.

The bottom line

The Addtam power strip solves the two biggest frustrations I have with power strips: cramped outlets and poor reach. The three-sided, widely spaced layout works, the 10-foot flat cord makes placement easy, and the right-angle plug avoids furniture gymnastics. Safety features are in line with what I expect, and the ETL listing adds confidence. The USB ports are handy for everyday devices, even if they’re not a replacement for a dedicated fast charger.

Recommendation: I recommend this strip for home offices, dorms, and general household use where you need a lot of outlets in a compact, mountable package. It strikes a smart balance of capacity, safety, and physical design at a fair price. If you need laptop-grade USB-C power or top-tier surge capacity, pair it with your existing chargers or consider a higher-joule model. For everyone else, this is a dependable, space-efficient upgrade that cleans up power delivery without fuss.
