Koonie Compressed Air Duster, 15000mAh Cordless Air Duster & Vacuum 2 in 1 Powerful 77000RPM/11000PA 2 Speeds Electric Air Duster with Detachable Battery, for Computer/Keyboard, Car, Electronics

I mainly bought this piece for my photographic purpose since I am a wildlife photographer and work in dusty conditions. I was looking for a very compact, hand held, cordless vacuum cleaner to ward off the dust during interchanging of lenses in the field and fortunately, found this little piece. Now, I am very happy and satisfied that this piece of gadget does both the vacuum and blower and can also be used as a power bank to charge the molbile and has now found a permanent place in my camera bag. The regular rubber blower brush has now been removed from my gadget bag.!!??

No tiene la fuerza de un bote de aire comprimido, pero si la necesaria para remover polvo y terminar con algo de aire comprimido en bote

I, like a lot of people I'm sure, spent a lot of time searching for a wireless vac/blower/whatever to help with certain tasks. I dubiously settled with this one because of other people's reviews (and it would arrive the same day). Pros: 1. The battery life is quite good for what it is. 2. The blower/suck function has quite a lot of power for its size. 3. I haven't tried the power bank option but I have no doubt it will work well. Cons: 1. It's quite loud. 2. The blower nozzle isn't detachable (as far as I can tell) and feels like it could snap off if you look at it wrong. 3. The vac debris compartment isn't the biggest and the filter can be one blocked quite quickly. Overall, it's well worth buying IMO. The main body is quite sturdy and if/when the blower nozzle breaks, I'm sure something can be rigged up easily enough.

These days, as with most products, the prices have gone up and the price of compressed air seems to be around $8 a can unless you can find a multi pack but things like this tend to be out of stock often. I've considered buying a powered air duster for a few years but was always put off by the high prices. I've also noticed a lot of them have reviews saying they just aren't strong enough to be comparable with a traditional can of air. When I found this Koonie model, I decided if I'm going to pay the high price for a cordless duster I might as well buy the most powerful one I can find. Right off the bat I like the size of the unit. Without the vacuum portion attached it's about the same size as a can of air. At first I thought not having a variable trigger would be a con but since you don't have to use short spurts like you do with a can, it's not a problem to just press the button and leave it on, and then just press if again for the high mode or to turn it off. I was impressed with how much air it moves, I recommend just always using the high mode since you're paying more for this model because it's more powerful than others. I didn't want or need the vacuum portion since I have a Dyson that is pretty portable itself but I decided to try it and was impressed with just how good it works. You obviously don't have much of a collection for debris but the filter itself is very sturdy and washable. I now use it for very small jobs like vacuuming air filters for the air conditioner and air purifiers, along with any small messes. The other huge benefit with this unit is the large built in battery. I've been using it quite a while and still haven't needed to recharge the unit yet, and when it do it's no big deal as I'd rather charge it than have to buy a new can. Charging does take quite some time but it's understandable due to the large battery. You can use the unit as a battery bank but I don't because I'd rather save all of the battery for runtime on the unit itself. The included attachments are very useful as well. I'd say this duster is more powerful than a can of compressed air but compressed air is still better in some situations due to the much smaller and more precise tip used on the cans. If you use attachment with the brush on the end you get a near perfect result as the brush loosens the dust and the air blows it away. The only thing this Koonie needs is a precision tip to add onto the end of the tube and it would be perfect and better than compressed air in every way. I'm sure a determined person or someone with a 3D printer could make such a tip if Koonie themselves pass on the opportunity. I like the power of this unit, great build quality, long run time, and the bonus of a decent hand sized vacuum and it'll end up paying for itself by the time you save yourself from needing to buy more cans of compressed air. I did a review of this Koonie air duster on my YouTube channel. If you search "Koonie Air Duster" you'll likely find it on my channel Mr Everything, as I'm not sure a link will post in this review.

I use it to clean my computer and my keyboard and i love it. For light jobs it is exactly what i was looking for. Don't expect a super powerful blower or vacuum like electric one. Like i said very good for light jobs. And here is a tip ! After i clean my glasses with water and soap I just use the blower to dry up my glasses it take 5 seconds and done. Nice and clean and no stripes. Let see how long the battery will last. So far so good.
