BKSAI Magnetic Blackout Blinds for Bedroom Windows (No drilling, portable, magnetic fixings) – 130x145cm

The essentials

If you’re trying to make a room genuinely dark without committing to permanent installation, BKSAI’s magnetic blackout blinds are built for that job. The idea is straightforward: a blackout fabric panel that you can put up and take down quickly using magnets, so switching between day and night is something you can do on an everyday basis. The fabric is described as high-density 420D oxford, and the brand claims it blocks out light and helps reduce indoor temperature.

This sort of window covering tends to suit people who don’t want screws, don’t want to drill, or are living in a space where you’ll be moving things around—think rental flats, temporary rooms, or travel. On paper, this one also leans into portability, as it’s foldable and designed to fit into a bag or suitcase.

Key features that matter in real life

What stands out here is the method of fixing. Instead of drilling, it uses magnets and hook-and-loop strips (the strips are described as optional to omit). The listing also says the “new version” has increased magnetic field by 50%, which suggests BKSAI is aiming at better hold—particularly important if you’re fitting it to a window that might get bumped.

The blackout fabric also has a practical extra layer: one side has a special silver coating intended to reflect sunlight and reduce incoming heat. That’s relevant in summer, when “dark” isn’t the only problem—bright sun can turn a room into an oven.

There’s also a trimming element to make it flexible: the panel is cuttable to fit windows up to 130x145cm, with a recommendation to leave a 4cm margin when trimming to help prevent light leakage around the edges. That detail matters, because blackout blinds often fail at the edges rather than in the centre.

What you’ll notice in use

Imagine it’s early morning and your household wants to sleep in. You measure your window, trim if needed, and then stick/position the material without drilling. With the blackout blind in place, you should expect the room to feel noticeably darker, which is the point if you’re a light sleeper or you’re shifting your routine around childcare or night shifts.

Another everyday angle is temperature comfort. The listing claims the silver-coated side reflects sunlight to reduce heat entering the room. It’s not a replacement for proper insulation, but it can be a useful addition if your window gets direct sun.

One small limitation to keep in mind: because it’s a removable, magnetic setup, your results can depend a fair bit on how smooth the window frame area is and how securely the magnets sit. If your window geometry is odd, edge gaps can still be a thing—hence the trimming margin guidance.

Where it shines, and where it might not

This is a solid fit if you want blackout coverage for the bedroom, nursery, or any room where you need darkness for sleep, and you don’t want to drill or leave permanent fixtures behind. It also makes sense if you’re planning for temporary use—holidays, camping-style trips, business travel, or a rented place where you can’t modify the windows.

It may not be the best match if your main goal is perfectly uniform blackout with zero edge spill regardless of setup. Removable blinds can be great, but they tend to need careful measurement, correct trimming, and good placement to avoid small gaps.

You may want to skip it if you expect a “set-and-forget” permanent installation feel—this is designed to be pulled up and taken down, not mounted for life.

Should you buy it?

Buy it if you’re after portable blackout for windows where drilling isn’t an option, and you’re happy to measure, trim (leaving the recommended margin), and position it carefully so the edges don’t leak. It’s especially appealing for babies, kids, light sleepers, and night-shift workers—anyone who benefits from a darker room on demand.

Skip it if you need guaranteed blackout performance with no light leakage under all conditions, or if you prefer a permanently fitted solution. Also, check that the up-to size (130x145cm) and the shape of your window are likely to work with trimming, if your window area is much trickier than expected, you might find the fit takes more fiddling than you’d like.
