## Description

Koumeican the thinnest extension (power) cord in the world 0.0354-Inch Flat Code 6.56-Feet Black - desertcart.com

Review: Very low profile - It is just like the description in that it is very thin, you barely know you are standing on it and even on a flat floor there is little chance of tripping on it. I have a laminate floor with a medium traffic walkway and I needed an extension cord across it and works well. I did have to use double stick tape to get the edges flat. It is not at all cheap. But I could not find any other product that is as flat. I have had it two months. Time will tell how durable it is
Review: Amazing if you work around the polarization problem - The thinness of this cable is unreal. Amazing engineering. As others have stated, the wire is not grounded NOR polarized. I wanted a cable to run across my black hardwood to a central dining table. To work around the polarization problem, I took a 3 prong to 2 prong adapter... then took tin snips to the wide blade of the adapter to make both blades be small and fit into the cable. I had planned to use a dremel but didn't need to. I used a multi-meter to ensure that I plugged the "polarized" side into the same side as the polarized side of the outlet. It may not be the safest option but it's impossible to match the thinness otherwise. Hopefully they'll start producing a US version.

## Features

- We have never seen it! Flat type (like a sheet) of an extension power cord of 0.9mm (about 0.003-Inch) thick.
- Resolve problems of previous cords which you have had, for example they are caught by something or bulky. You can make a safe and clean room by laying cords under carpets and mats, no bumps.
- This is 0.9mm (about 0.003-Inch) thick, so it gives you the electlicity through any gaps for example, the closet, out of windows, out of doors and places where you thought that it was impossible to have.
- Flat parts only come with a lifetime guarantee. (Free for repairs, but shipping cost (round trip) will be charged.)
- Conducted the test : passing the chair on casters with 90kg load on the code for 20,000 times. No breaking. Conducted the withstand load test : put 50mm diameter round bar on the flat part, apply 4 ton load. No breaking. It might be made wrinkles due to the temperature. You can straighten it by the hot air from a dryer.

### ⭐⭐⭐⭐⭐ Expensive but exactly what I needed
*by G***1 on February 4, 2024*

Bought 2 of these in different lengths to go under a floor rug so we could power 2 electric recliners. Can't even see these under the rug and work perfectly. Glad we bought them even though they are pricey.
