COSANO Full-Metal Jet Dry Mini Blower – 300,000 RPM Electric Air Duster – Rechargeable Compressed Air Blower – High-Power Air Duster with 3 Speeds & 4 Nozzles for Keyboards, Car and Outdoors Cleaning

I picked up this electric air duster mostly to replace disposable compressed air cans and after using it for a few weeks, I have found that it's much more practical. My initial impression was the power. It features three different speed settings which I've found useful. The lowest speed is enough for light dust on my desk and electronic, the medium works well for cleaning inside my PC case, and the highest is what I use for more stubborn dirt or outdoor jobs. On the highest setting, it's actually strong enough that I had to be careful the first time I used it on my keyboard because it can actually move keycaps of my keyboard if I get too close. The mini blower also features four different nozzles and I've actually used all of them for different scenarios. Swapping them out is simple and feels secure, they don't pop off mid-use. I also like that it has recharging capabilities to increase it's lifespan. The battery life on a full charge has been decent so far. I can clean my keyboard, desk area, and parts of my car interior on a single charge. ON the highest setting, it evidently drains faster given the power to output. All in all, this was a smarter and more convenient investment for me than the compressed air blowers.

Very good air blower, it’s strong and powerful, gets all the dust out from the unreachable nooks and crannies. It’s also lightweight and compact making it easy to use. It’s also multifunctional with multiple attachments. I also use this to start up a fire wood for the bbq grill, which is way better that fanning it.

"I absolutely love this air duster! It's incredibly powerful and does a great job at cleaning my keyboard and even the hard-to-reach spots in my car. The three different speed settings are perfect, and the nozzles included allow me to choose the right one for every task. It's so much better than canned air and is rechargeable, so I don't have to keep buying refills. The build quality is solid, and it's surprisingly quiet for such a powerful blower. Highly recommend it!"

This thing is small and powerful. Great building quality as it's made out of metal and not cheap plastic. I use it to clean dusks from keyboard, pc and laptop fans and it works great. I also use it to blow the leaf off my car as I park under trees. It's rechargeable and comes with multiple types of attachments for different uses. The noise level is acceptable as expected from a powerful fan.

HUGELY DISAPPOINTED! DO NOT BUY! Read and watched the many reviews. I agree that it is very powerful as advertised but the biggest defect is the battery drain when off. The device had been fully charged, turned off and has sat for a week or so and battery fully discharged and depleted. Again, this was repeated several times and same result. I made sure it was not accidentally left on. Believe me, this is a terrible product with a defect. Perhaps its isolated to my unit. No idea and I am out of the return window. This is an update based on a follow up by the company. I did not expect for anyone to reach out to me to offer a resolution. I was very pleased with the outcome as they stand behind their product. I'm sure that mine was an isolated defective item since many others are satisfied. Like I said, it really is incredibly strong but the battery sustainment was the issue. Also I noticed that when full charge is achieved, the item can only be used for a short duration and instant battery drain to zero. I did use several different USB cables at the recommended AMP and Voltage. Thank you very much for the immediate follow up from customer support.

This is my second miniature compressed air blower and it is way stronger than my other one. With how small and compact it is, its crazy how strong this thing blows. Build quality feels very nice with the metal. Much more premium feeling than my other plastic one. Battery is decent especially for how powerful it is. Its a useful little tool. I use it mainly for cleaning my electronics. Its nice not to buy consumable cans of air. Have also been using it on my truck while doing engine work to blow out dust and debris. Its easier than pulling out the air compressor

Very strong dryer. I gave this 4 stars just because it takes forever to charge. This is my second. The first one I received would not turn on. Amazon replaced it no problem.

I really like this mini blower because it has very strong power, with this mini blower I can also clean snow or dirt easily, its small size makes it easy to carry or put anywhere without taking up space, the battery life is also very long, I am really satisfied with this mini blower.
