This electric brushless air duster is an absolute beast. The motor is insanely strong, delivering impressive wind power that blasts away dust from computers, AC units, window crevices, and even clears leaves outside. The 2-in-1 blower and vacuum feature is genius — it blows from the front and vacuums from the back, so there’s no leftover mess.

The magnetic nozzle snaps on instantly, and with the included brushes, it handles everything from delicate electronics to outdoor cleanup. The dual LED lights are surprisingly handy for dark corners or nighttime use, and the SOS strobe is a clever bonus for camping. The battery life is excellent — plenty of runtime for multiple jobs — and the safety auto-shutoff keeps it protected during heavy use.

Good purchase

I got this K&F Concept 2-in-1 magnetic compressed air duster, and it's been a powerful tool for my cleaning routine. This electric air duster, with a 300,000 RPM vacuum cleaner, offers 3 gear settings and super wind power, perfect for cleaning computers, keyboards, cars, homes, or outdoor spaces. The rechargeable brushless motor provides strong airflow, effectively removing dust from hard-to-reach areas, and the magnetic attachment lets me secure it to metal surfaces for hands-free use. The 3 gear settings allow me to adjust the intensity, from gentle for delicate electronics to strong for tougher jobs, and the device is lightweight, making it easy to maneuver.
The 300,000 RPM motor is impressive, but it can be a bit loud on the highest setting, so I use it in shorter bursts, and the magnetic feature is handy but not super strong, requiring a flat metal surface to stick well. The rechargeable battery lasts about 30 minutes on a full charge, which is sufficient for most tasks but might need recharging for extensive cleaning. The device comes with multiple nozzles for different applications, enhancing its versatility, but the plastic build, while durable, can feel a bit flimsy compared to metal alternatives. Overall, it's a practical, innovative choice for dust removal, and I'd recommend it for anyone needing a versatile cleaner—just manage the noise and recharging!

This is a fantastic little device. It replaces the compressed rid can type cleaners, and is great for cleaning out dusty PCs and other dusty items.

It has 3 levels of blowing strength, that I would describe as mild, stronger and hurricane! It really is very powerful, and can easily blow my wife’s hair around from right across the room. Which is fun but annoying apparently…

With various attachments, including ones to utilise its suction force as a vacuum cleaner, it is certainly very versatile.

It removed loads of dust from the inards of my PC, but I did complete the job outside, as it blows dust everywhere! It also has a tendency to suck dust back into its own air intake, so I had to clean that a couple of times.

I find it hard to believe that such a small item can blow so hard! It also has a usb c charger, so it can be kept topped up and ready for action.

I am also going to use it to trace a mysterious wind noise from around my car window seal.

Wholeheartedly recommended!

Despite its small size, the 300,000 RPM brushless motor delivers incredibly strong and consistent airflow, perfect for blowing dust from even the most remote corners of a PC case. The 3 speeds are very useful, allowing me to use a gentler setting for cleaning the keyboard or fragile objects and a higher setting for more aggressive cleaning. The 2-in-1 vacuum and blower function is brilliant: I use compressed air to remove dust and then vacuum up crumbs and dirt from my desk or car. This device is extremely practical. The 2 built-in LED lights are a fantastic detail: they perfectly illuminate dark spaces, like the inside of my computer or under car seats, allowing for much more thorough cleaning. It's compact, lightweight, and conveniently recharges via USB-C, eliminating the need for disposable batteries. It's a much more eco-friendly and economical solution than disposable canisters. It's made cleaning faster and more efficient, and its portability makes it perfect for any need.

Thanks to the "Amazon Vine" program, I was able to receive this blower. After testing it, I can share a comprehensive review with you, listing the pros and cons I found:

PROS:

• Very powerful portable blower. I used it to remove dust from my desktop computer's motherboard and blow dirt off my car's carpets; I was pleasantly surprised.
• Equipped with a brushless motor, it guarantees a longer lifespan and is maintenance-free compared to traditional motors; the brushes do not need to be replaced.
• Three power levels can be set based on the type of surface or the degree of dirt being cleaned.
• It has two built-in LED lights that illuminate darker areas during cleaning.
• Built-in rechargeable battery that can be charged via a standard USB-C charger if you don't have an electrical outlet; it's compatible with a power bank.

CONS:

• Very noisy at maximum power, which can be annoying, especially indoors.
• At maximum power, the battery drains quickly, with a runtime of about 10-15 minutes.

In conclusion, I consider this K&F tool a practical and powerful solution for those who want to keep electronics or cars clean. Equipped with a powerful brushless motor that reaches up to 300,000 rpm, 3 speed settings, LED lighting, and a portable, USB-C rechargeable design, it's one of the best blowers on the market for home use.
