Compressed Air Duster, 3 in 1 Cordless Electric Air Duster, Vacuum & Inflate Swimming Ring, 3 Gear Adjustable 100,000RPM Handheld Mini Car Vacuum Cleaner & Keyboard Air Blower with LED Light (Black)

Pretty strong
This is a surprisingly effective solution to the bottled air duster. The turbo fan and small nozzle shoots out a concentrated stream of air that will blast any crumbs out of your keyboard. Even the lowest setting is strong. The multiple types of heads are also effective for different situations. I use this to blow up pool inflatables too, with some of the head adapters. The battery also lasts a couple hours, and with each use just a few minutes at most, it lasts a really long time with each charge. The price is also a lot better compared to when I saw these for like $80 each a couple months ago.

Works great
I bought this for my job and this works great I don’t use the vacuum part of it so not sure on that part used it for balloons for a party and a few toy for the kids for the pool and deflated as well

Good fit for my car
Great fit for my car. Powerful and easy to use

Good little duster with lots of great attachments
This is a nice little duster. It isn’t the most powerful of those that I own, but it’s not the most expensive either. Despite being listed as 100,000 rpm it bests units with a rating over 130,000. It’s battery lasts a good amount of time and it has plenty of accessories.

First off, the electric air duster I received (brand RELAXYO) bears little resemblance to what’s described on the product page, but that’s actually a good thing. Note my photo. Second note before I dive into the details is that another reviewer of this item, SMB, clearly received the same product I did and has an excellent highly technical review that is worth a read.What I received is a small hand-held duster with an entirely metal body, battery indicator LED (4 point), rubberized power switch, and an analog slider that controls the fan speed (and therefore blowing force). The manual says it’s a Mini Jet Fan model J01. Contrast to the product description for the VC019, which mentions a “3 gear” blower with illuminating LEDs. The analog speed setting is quite superior to fixed stages, and I don’t need LED illumination of the space. The product description mentions 10 attachments and a removeable washable filter; this item has 4 attachments, one fixed screw-in metal nozzle adapter for the attachments, and no removeable filter (that actually might have been nice). In short… the product description seems to be out of date.That discrepancy aside, this is a great little duster. It’s got some serious heft for its size, and the body is entirely metal, including the screw-in adapter ring which can fit either end. This swaps between blower and vacuum simply by the direction you orient the attachments. As it has NO FILTER, I don’t recommend the vacuum option *except* as a cordless deflator. The metal adapter ring functions as both a directional attachment, and as the connection point for the plastic/silicone accessories. They consist of one long plastic tube with a brush, a conical inflator insert suitable for inflatable water toys (the small valve type), and a short plastic attachment that can be used as a director on its own, or with a silicone gasket suitable for large inflation ports.On the technical details:-I did not measure battery life. It came charged at 3 pips, and was fully charged within about 30 minutes on a 2A USB wall charger. If you care about long-term use without charging, a corded version may be the better choice. For a few minutes of dusting, it’s more than sufficient.-Blower force: using the metal screw-in nozzle only, from a distance of ~15 cm (6 inches-ish), 96g of force on a digital kitchen scale on maximum. DO NOT use this on maximum close to PC components, you risk damaging them.All in all, the product I received is a pretty impressive little cordless duster. At time of order and review it was $80 CAD, which is about what I’d expect to pay for something of this quality. Just exercise caution before you order based on this review that what you get is actually the same thing, since the discrepancy between description and what was received is quite large – so large, in fact, that that is why I knocked off a star because the seller really needs to do better.

There are many choices of cordless air duster on amazon but there are surprisingly FEW that actually deliver or even remotely close to being powerful enough to do the job. Well, this is one of those that actually delivers and that’s a rare find to say the least. There is always room for improvement but it has decent performance for what it is and that’s good enough for me and suits my needs.≡ NoteWhile the vast majority of air dusters make their claims about the performance of the motor based on air flow/speed, and so does this one; however, air flow/speed depends on the area/circumference of the outlet which can be difficult to get a good handle on but more importantly is the fact that air speed doesn’t always correlate to air pressure which is what’s needed to REMOVE dust.As such, I’ve moved away from using air speed/flow to determine the effectiveness of these air dusters and instead use the downward air pressure or force (i.e. weight), with the help of a digital scale, to determine how much force it’s exerting outwardly to remove dust (or any other objects for that matter) instead of the usual air flow (CFM) or even air speed (m/s).###I’ve been using the canned duster for more than 22+ yrs ever since they became available from a local wholesaler chain and they’ve been working great since (and a MUCH lesser degree since I started using electric air dusters 9+ yrs ago). I have come across quite a few of these electric air dusters ever since I broke the chain of ‘refilling’ but I’m constantly on the lookout for a better and more powerful electric air duster because sadly in some unique situations the canned duster still reigns supreme (e.g. for very sudden and short burst of air in tight spaces).≡ BuildIt appears to be rather well-built and the handle seems sturdy as well and unlike the other one that has an upward tilt which I find awkward holding it in my hand while operating (moving it around cleaning the keyboard etc) the duster, this one actually has it oriented the normal way which is just at a [roughly] 90° angle.What surprises me the most though is the fact that the inlet/outlet part of the duster is made of metal including one of the multi-use nozzle. Btw, it’s also noticeably smaller than expected which is yet another pleasant surprise that greatly increases its usability and ease of use.It claims to have 2x 2000 mAh battery and with up to 100K RPM but neither is verified so I’ll just take their words for (which usually turns out to be a mistake by I digress).≡ ChargingIt can be charged via USB-C which is great but it doesn’t support PD/QC so it can and certain does take a few hours (3-3.5) to fully recharged a depleted battery. In any event, it does draw close to 5V/1.5-2A so that’s not too bad although this should really be charged via USB wall chargers (or other dedicated USB chargers instead of computer USB ports because they are limited to 0.9A max).≡ Spec/featureIt comes with 5 attachments which is nice (actually only 4 attachments since the 5th one (the metal one) is used to interconnect the others with the duster itself. It also comes with a soft rubber vacuum nozzle which I can’t say I’ll ever use as I have no intention to use this as a vacuum. As aforementioned, I have/had more several dozens of these electric dusters (including a makeshift yard blower which works great in some situations) in the past but many of them didn’t live up to the expectation.While many aspects of the product matter, the crucial thing I really care about is how much force it can exert onto a surface and in this case how much dust or other small/fine particles it can actually remove. For this particular air duster, I’ll be testing it with a digital scale as aforementioned and see how it goes.It has a stepless speed control/adjustment which I very much appreciate (and indeed prefer overall others if given the choice). It does have push-button for turning it on/off though. This is ONE of the most well-built and well-performed air dusters of THIS SIZE that I’ve over come across and that’s certainly a point in its favor.It does NOT have a LED as advertised and while we’re at it, it also doesn’t have a 3x speed control as claimed (someone really needs to fix the ads/description because there are just so many typos and/or discrepancies. In any event, I’ve never needed a LED from an air duster and probably never well.≡ PerformanceAs aforementioned, a digital scale is used to determine how much pressure/force it exerts onto its surface. As a control/reference, I also included the results from another 120K air duster ad the results are below;This air duster : 82.5 gram of force (100K PRM)Other air duster: 82.8 gram of force (120K RPM)I have to say; the result is surprisingly good (partially because the vast majority of others make outrageous false claims all the time whereas this one doesn’t) and I’m glad to see that it does perform reasonably well within what it claims to do. Well, numbers don’t lie and while I have no idea whether this is actually 100K RPM or not, at the highest it does beat another similarly spec’ed air duster, by as much as 5% (rated at 110K RPM) which is not bad, not bad at all.≡ NoiseWell, it’s quite loud and that’s expected. As a comparison, it’s comparable to a typical handheld vacuum cleaner based on perceived loudness (since it’s closer to you). You should NOT expect this to be quiet and if it is, it probably doesn’t perform well because in order to move air at higher speed, it MUST be noisy until such time that we have new physics or technologies to show us otherwise (well, we aren’t there yet).≡ ValueAll things considered, this is a fairly decent cordless air duster that performs fairly well given the results of the test. It moves significant amount of air and it’s without a doubt more powerful than most other cordless air duster out there. It’s reasonably priced at $80 for what it provides and its overall build quality, features, usability, and performance.; however, if you do NOT require cordless or if you can live with a corded air duster, there are quite a few corded options that far outperform this (and perhaps every single one of these cordless dusters) if that’s something you are willing to consider.
