TIANMU Electric Compressed Air Duster, Strongest 3-Gear to 90000 RPM Powerful Air Dust Blower, Replaces Cordless Air Cans for Keyboard PC Camera Cleaning, 7500mAh Rechargeable Battery, 90W (Blue)

After sorting through so many different products, I took a gamble and picked this product based on its performance and high RPM speed vs the cheaper models. Why? I was tired of spending so much money on canned air, plus the cans would get super cold. As soon as I got the product, I put it to the test. I acquired an old never cleaned amplifier from the 1980s and posted the before and after pictures. Dust was flying everywhere! By the time I was done I had a new amp. Pictures speak more than words, so check them out.

This device puts out a strong and narrow stream of air, and has three increasingly-powerful speeds. (I put it to the ultimate test: it blew leaves off my small outdoor decks quite well). There's also an extension with a brush on the end for narrow spaces. The main nozzle folds down for easy storage in the cloth bag. It has a heft but a reasonable weight for what it does, and it's fairly compact. Highly recommend.

Update: Great customer service & support till the problem is solved. The previous item has issues and so I had to return the item but I was sent another new item that is working perfectly and is in good condition. The product size is handy and works well to remove dust from keyboard, makeup vanity, skin care products, little dust over hanging clothes, small tech items like mic, speaker, laptop stands etc. Also great use in small areas of car interior.Previous purchase: It never started so I had to return.

Works really great. Didn't expect would be that powerful with 3 speeds. Almost like hair dryer. Bit noisy then expected but works great. Definitely replaces the other duster sprays

Practical, as it has no cord and not heavy. Powerful enough, with 3 different speeds, I use it for my car and my keyboard on computer. The battery lasts longtime.

Got all ps4 and pc clean in min

This air duster is not bad at all, but I think the lack of dust filter may become an issue in the long term.The amount of power this cordless duster outputs is comparable to a brand new can of compressed air, but where this cordless duster really shines is in its battery life. A can of compressed air will start to lose output strength, as the can uses up its stored energy, but this cordless duster outputs at a constant rate until the battery runs out. And the battery lasts a long time.I also happen to have a very popular 500W corded duster, and that absolutely trounces this cordless 90W duster.However, if you don't need that much power, this cordless duster is significantly easier to use, as it is lighter and doesn't have a heavy cord.This duster charges off of a USB-C plug on the back of the handle, and it also includes a USB-A to USB-C cable accessory.There are just two issues I have noticed with this duster.One is the panel fitment quality. The intake grill/cover at the back of the duster has a rather uneven seam, and this gap is wider at the sides, compared to the top and bottom. This uneven seam has no effect on the function of the duster, but it does look unsightly and feels cheap.The other issue is that the air intake impeller has no dust filter. On many hand held products that use high RPM air movers, like vacuum cleaners and dusters, there is usually a dust filter to protect the impeller and motor from dust, but this cordless duster does not have that.Looking through the grill at the back, the impeller is completely visible. Now, it's probably okay for some fine dust to get in there, but what about strands of hair, or larger particles like saw dust? The long term results of this duster accidentally ingesting hair or larger particles, I can't really say with certainty. I only know that other similar products use a washable filter here.
