TESSAN — Is the TESSAN Surge Protector Power Strip Worth It?

The moment

Why your desk outlet always runs out

You've got three things that need power and one outlet behind the desk, so you're stacking cheap adapters on top of each other like a bad game of Jenga, and the whole pile shifts every time you plug in a phone. Somewhere in the back of your mind you're wondering if any of that is actually protecting your laptop, or if it's just a fancier extension cord with a price tag attached. That's the real question with the tessan surge protector power strip: does the surge protection part do anything, or is it just eight outlets and a switch.

The mechanism

How the tessan surge protector power strip actually protects your gear

Here's where your money actually goes. Inside the strip sits a metal oxide varistor rated to absorb 900 joules before it gives up, think of it as a sacrificial fuse that eats a voltage spike so your laptop charger doesn't have to. That number matters more than the outlet count, because eight outlets on a strip with no MOV is just a splitter with delusions of grandeur. Once the spike happens, the part burns itself out quietly and the strip keeps running like nothing happened, which is the honest trade: you're paying up front for insurance you hope to never use. The rest of the design is solving a different problem, which is real estate. The plug is flat, so it sits behind a desk or TV stand instead of hanging off the wall at an angle, stealing the outlet under it. The eight sockets are spaced wide enough that a wall wart on one side doesn't block the socket next to it, which sounds small until you've tried plugging four laptop bricks into a strip and losing two slots to plastic. Add three USB ports, one of them USB C, and you can drop the charging bricks for phones and tablets altogether, freeing up an actual outlet for something that needs one. The switch on the end kills everything at once, which matters more for a strip sitting under a desk where reaching six individual plugs isn't happening.

The click

So the outlet count is the part you see and the joule rating is the part you're actually buying. Eight sockets you can get from a five dollar splitter. A strip that eats a power spike so your gear doesn't is the actual product here, and that's the only thing worth paying extra for.

Who it's for

Who the TESSAN power strip is for, and who should skip it

Worth it if

you have one outlet and multiple devices to power
you want real surge protection, not just extra sockets
you charge phones or tablets via USB and want to free up outlets
you need a flat plug that sits behind furniture

Skip it if

you're trying to run space heaters or high draw appliances through it
you need more than 5 feet of cord reach
you want a strip with individually switched outlets

Not for garages, space heaters, or anything that pulls real amperage, this is a desk and electronics tool, not a general purpose power outlet.

The verdict

The TESSAN surge protector review verdict

If you've got a desk, a dorm, or a home office with one outlet and six devices, this is a quiet yes; it solves the outlet math and gives you real surge protection for not much money. If you're trying to daisy-chain extension cords across a garage or run space heaters through it, skip it. Surge strips are for electronics, not appliances pulling real amperage.

The problem this solves is small but constant: the outlet hunt, the adapter stack, the mild dread every time a storm rolls through and you wonder if your laptop charger just became collateral damage. Day one looks like plugging in the laptop, the monitor, the phone charger and the desk lamp, flipping the switch once, and not thinking about it again for years. That's really the whole point of a surge strip: it's supposed to be boring.

Amazon shoppers rate it 4 out of 5 across 13,953 ratings. That is their number, not ours.

Before you go

Is TESSAN a Chinese brand?

Yes, TESSAN is a Chinese electronics brand that manufactures and sells power strips, adapters and surge protectors, most of it through Amazon rather than retail stores.

TESSAN's surge protector strips include surge suppression circuitry and standard safety certifications, so they're built the same way as other listed surge strips on the market.

Is TESSAN power strip a surge protector?

Yes, this model carries a 900 joule surge protection rating, meaning it has internal circuitry, typically a metal oxide varistor, that absorbs voltage spikes rather than just splitting an outlet.

What should never be plugged into a surge protector?

High draw appliances like space heaters, window AC units, hair dryers and refrigerators shouldn't go through a surge strip, they pull more current than the strip is rated for and defeat the point of surge protection.
