Flat Plug and grey three sided body" width="1200" height="800" loading="lazy" style="height:auto">
Every desk I have ever owned has ended up in the same state: a tangle of chargers fighting for one or two wall outlets. Power strips solve that, but most of them are solved the same lazy way, a row of sockets that never quite fits the bulky adapters everyone owns. The TESSAN Surge Protector takes a different approach. It wraps the outlets around three faces of the strip, adds two USB-A ports and a USB-C port, and backs the whole thing with 900 joules of surge protection. I ran it on my work desk for two weeks to see whether the design holds up to a real load of computers, monitors, and phone chargers.
Before the details, the standard note. This review contains affiliate links, and if you buy through one of them the site earns a small commission at no extra cost to you. That does not change what I test or what I recommend. I treat every product here exactly the way I would treat one bought with my own money.
Design and Build
The first thing you notice is the plug. TESSAN ships a flat 45 degree plug that lies nearly flush against the wall, and that single decision makes the strip feel more considered than most of the competition. The cord is 5 feet long, which is shorter than the 6 foot cords on some rivals, but it is enough to reach behind a desk or a bedside table without strain. The body itself is a compact grey block with sockets on three sides, and that orientation is the reason the strip works.
Most power strips arrange their outlets in a single line, which means one wall wart covers its neighbours and half the sockets become unusable. The three sided layout spreads the sockets out, so a laptop charger, a tablet adapter, and a cable box brick can all sit together without touching. In my two weeks of use I never once had to unplug one device to reach another, which is more than I can say for any single row strip I have owned.
The build quality is reassuring for the price. The plastic shell has no flex, the rocker switch clicks with a firm action, and the 8 AC outlets are spaced generously enough for most adapters. The USB ports sit on one of the faces with a small indicator light that shows the surge protection is active. It is not a heavy metal enclosure, but nothing here feels cheap in the hand.
Key Features
The headline specification is the 900 joule surge rating. Surge protection is measured in joules, and 900 is a solid middle ground. Basic strips often sit around 200 to 400 joules, which handles minor spikes, while commercial equipment moves toward 2000 joules and beyond. For a desk full of household electronics, 900 joules is appropriate, and the indicator light gives you peace of mind that the protection circuitry is alive.
The USB side is where the strip stands apart. You get two USB-A ports and one USB-C port, and the USB-C port charges considerably faster than the A ports. In my testing the USB-C port pushed my phone from empty toward full noticeably quicker than the USB-A ports beside it, which makes it genuinely useful rather than decorative. The A ports are slower, more suited to overnight charging of earbuds or a smartwatch.
The final feature worth mentioning is the master switch. A single rocker cuts power to all outlets and ports at once, which lets you kill the vampire draw of idle chargers with one press. For a dorm room or an office desk that gets turned off at night, that is a small but real convenience.
Real-World Performance
I set the strip up on my desk with a demanding load: a desktop tower, a 27 inch monitor, a laptop charger, a router, a speaker, and a phone on the USB-C port. The strip handled all of it without complaint, and the sockets stayed cool to the touch even after hours of use. I checked the plug temperature after a full afternoon of charging and found nothing beyond mild warmth, which is a good sign for the internal wiring and the pass through design.
The three sided layout proved its worth in daily use. On my desk I have a charger with a chunky brick and two adapters with wide plugs, and all of them live on the strip side by side. With a conventional strip I would have lost at least two sockets to the adapters covering each other. The flat plug also mattered more than I expected, because my desk sits against the wall and a standard right angle plug would have pushed it out by an inch or two.
The USB-C charging speed was the pleasant surprise. I charged a mid range Android phone and it went from 40 percent to full in about an hour and a half, which puts the port well ahead of the trickle charging you get from most built in USB ports on power strips. The two USB-A ports are slower, but they are fine for accessories that charge overnight. If your setup is heavy on USB-C you will still rely on your own chargers for the fastest speeds.
One honest limitation: the surge rating is not the highest available. If you are protecting a home theater stack or expensive AV gear, you may want more than 900 joules and a connected equipment warranty. For computers, monitors, and phone chargers, it is more than adequate, and the indicator light means you can verify the protection is active rather than trusting it blindly.
Pros and Cons
Pros:
- Three sided layout lets bulky adapters sit side by side
- USB-C port charges noticeably faster than the USB-A ports
- Flat 45 degree plug keeps furniture close to the wall
- Master rocker switch cuts all power with one press
- 900 joule surge rating with a status indicator light
- Solid build with no flex in the shell
Cons:
- 5 foot cord is shorter than some competing strips
- USB-A ports are slow, best for overnight charging
- No connected equipment warranty despite the surge rating
How It Compares
To put the TESSAN in context I compared it against two common alternatives: a basic multi outlet strip with no surge protection, and a pricier premium surge protector with a higher joule rating and a connected equipment warranty.
| Feature | TESSAN 900J Strip | Basic Power Strip | Premium Surge Protector |
|---|---|---|---|
| Surge protection | 900 joules | None | 2000+ joules |
| Outlets | 8 AC plus 3 USB | 6 AC only | 8 AC plus 2 USB |
| USB-C port | Yes, fast charging | No | Sometimes |
| Outlet layout | Three sided | Single row | Single row |
| Flat plug | Yes | No | Sometimes |
| Connected equipment warranty | No | No | Yes |
The TESSAN beats a basic strip in every way that matters, because the surge protection and the three sided layout solve real problems rather than just adding sockets. The premium option wins on raw protection and the warranty, but it costs significantly more and its single row layout can waste sockets to bulky adapters. For a desk or dorm, the TESSAN sits in a sweet spot most buyers will not outgrow.
Who Should Buy It
Buy the TESSAN surge protector if you have a desk or dorm setup where adapter width is the real problem, if you want a USB-C port that actually charges, or if you want surge protection without paying premium money. It is a straightforward upgrade over any unprotected strip, and the three sided design is the kind of detail you appreciate every single day.
Skip it if you need a longer cord, if you are protecting high end AV equipment that demands a connected equipment warranty, or if you already own a premium surge protector with headroom to spare. For everyone else, this is one of those rare accessories where the smarter design actually changes how you use it. You can check the current TESSAN surge protector price on Amazon when you are ready.
How We Test
I tested the TESSAN surge protector as the primary power source for my work desk for two weeks. That meant a desktop computer, a monitor, a router, a speaker, and a phone charging from the USB-C port, all running through the strip simultaneously for entire workdays. I monitored socket and plug temperatures, verified the surge indicator stayed lit, and timed USB-C charging from a partially drained phone to full.
I also evaluated the flat plug against a standard right angle plug in the same outlet to confirm the clearance difference, and I checked the master switch by powering the entire desk down and back up repeatedly. I did not simulate a direct lightning strike or repeat that kind of catastrophic surge, because no consumer strip can promise survival against that. For information on surge protection standards and joule ratings, outlets like PCMag surge protector guidance are a useful reference before you decide how much protection your gear needs.

TESSAN Surge Protector Power Strip: Questions People Ask
How much surge protection does the TESSAN power strip provide?

Does the flat plug sit flush against the wall?
Yes, the flat 45 degree plug lies nearly flat against the outlet, which lets you slide furniture close to the wall and frees the outlet below it.
