Manufacturer description
The TESSAN flat extension cord solves the problem behind your couch: a 0.31-inch ultra-thin plug head with a built-in pull ring, angled 45 degrees so it seats flush against the wall without blocking the outlet below it. You get seven charging points from one wall socket: four AC outlets plus three USB ports, including a 15W USB-C and two 12W USB-A, so a phone, tablet, and earbuds charge alongside a lamp and a monitor. The 5 ft flat cord reaches outlets stranded behind furniture, and it lies flat enough to run under a rug or along a baseboard. On the protection side, TESSAN rates the surge…
SpecPicks Verdict
SpecPicks scored TESSAN Surge Protector Flat Extension Cord 5 Ft using a rating × review-volume × price-fit model applied to published specs and reviews across the home & kitchen category. TESSAN's home & kitchen lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for home & kitchen of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How many devices can the TESSAN power strip charge at once?
Seven. It has 4 AC outlets, 1 USB-C port, and 2 USB-A ports, all usable simultaneously.
How fast is the USB-C port?
The USB-C port delivers up to 15W, and each USB-A port delivers up to 12W. That covers phones, tablets, and earbuds, but not laptop-class fast charging.
Will the flat plug fit behind a couch or TV?
Yes. The plug head is 0.31 inches thick with a 45-degree right-angle design and a built-in pull ring, so it sits flush in tight gaps and pulls out without wrestling.
Is 900 joules enough surge protection?
900J covers lamps, phones, routers, and small electronics with overload and short-circuit protection. For a gaming PC or home theater stack, step up to a higher joule rating.
How long is the cord?
5 feet, and it is a flat cord, so it can run along a baseboard or under a rug instead of bunching up behind furniture.
