The nozzle detaches from the unit and is able to clip on the side of it, which makes storing it easier.This item really does blow nearly everything out of its way, really good to clean keyboards with as it is extremely powerful. Ideal for those hard to reach areas for the vacuum can’t reach, like small gaps or most electrical items. It’s lightweight and very easy to use, takes a few seconds for it start working but after that it’s ready to go till the battery gives. Much easier to use compared to air cans and this is also safer for the environment. If you double tap the power button then it will remain on until you press it again to switch it off - found this to be handy feature for longer cleaning periods. Battery life is also decent and charging the unit only takes a few hours.

TIP: Charge the unit first with a 2A plug.TIP: there is a delay between pressing the trigger and it starting.TIP: this blows the dust in the air so consider wearing a dust mask and glasses.I work with a lot of electronic components and they just attract dust.It might not sound to big a problem but dust can cause components to overheat and pop. It can also create a conductive path which will short out a circuit. In both instances this will result in a broken unit.So prevention is better than cure and it's good practice to clean dust up. As electronics can be destroyed from static it's advisabe to avoid directly touching them unless you are earthed.So I mostly use the canned air to do the job. The only problem is these are pretty expensive for what is essentially air in a can.I therefore decided to give this air duster a try as a means to save money. It's not cheap but in the long run should save me money.This unit comes with a neat storage socket for the nossle to make it compact. To use you firstly must charge it, advisable to use 2A 5V plug like comes with a pad.You the simple pull the nossle off and push it onto the air outlet.You then press the trigger and use. To stop just let go.I was impressed with how powerful this is, if you point it at your hand it moves your skin a bit like a Dyson hand dryer. When using on computer fans it makes quick work of shifting the dust.All in all its a powerful unit that does a good job.If you liked my review please consider giving me a helpful vote and perhaps a follow for future reviews. Many thanks

This item arrived well packed and on time, happy with the service.However, as a user of compressed air for PC equipment cleaning I can say two things for sure.1.) It gets a good amount of dust off things, and can indeed blow and empty coke can across a desk.2.) It is nowhere near as powerful as canned air.The fan itself works fine, the add on nozzle, which is a loose fit at best, helps direct the air efficiency, but there is no real power behind this.I've maintained 3 stars as I'm sure many people will find this good enough, but if you're expecting to clear hard to reach dust, or such, then this will not be for you. Maybe down the road this type of item will have a more effective intake/ output version.

I had my doubts about this unit. It's expensive for what it does but it has enabled me to sell my small noisy compressor which also takes up valuable space in my furniture making workshop. I use this blower for cleaning tools and work surfaces of dust, particularly bearings on my bandsaw before servicing and adjustment. I find I'm using it all the time, but particularly at the end of the day when I blow everything down. I then switch on my air filter/cleaner on timer for an hour and lock up. The charging light could be brighter and the base more weighted. It holds it's charge well. Obviously, it's not as powerful as the air a compressor can provide but it works well for me. BTW, I used my compressor for air and to power an 18g nail gun, the latter has been replaced by an excellent battery operated tool. I now have a much quieter workshop!

I wondered, what if i buy a compact air blower instead of a compressor, and i was the most surprised man i believe, because i thought it's not that strong, and actually it is! The sound of this thing quite loud, but it's alright, because it's strong. The charge time is around an hour, and with a full charge i believe you can clean like 2 pc without problem. Also, really good for keyboard, PS4, and for every other stuff. Recommended!

I have a 18v 5000mah battery that drills bolts into hardwood that lasts hours and hours of use, this little 6000mah fan which puts out less then a spray bottle Psi is appalling for the price its a joke. and i think they are lieing, someone test their battery, if not then mechanically poorly designed as the side fan on the side of said drill blows more air haha!

waste of money - nothing like the focused blast of compressed air. Can’t fathom the positive reviews
