My first thought before receiving this air blower/duster was it may replace an aerosol can of compressed air to dust electronics and other items. My expectations have come true.**** PHYSICAL ****This air blower/vacuum operates on the same principal as a shop vac. The blower function is like the exhaust end and the vacuum function is like the suction/intake end.The air blower function has three speeds. There are two different sized air nozzles (photo 2). There is a vacuum function with three speeds, it has a removable filter (photo 12) and a detachable crevice tool (photo 14). A USB-A to USB-C charging cable is included. There is an optional internal flashlight that can shine through the air blower end (photo 13) while the blower is running.**** AIR BLOWER/DUSTER TEST ****My first use was to dust external USB cooling fans used on my router and cable modem that were long overdue (photo 7). I used the narrower nozzle versus the wider on high speed to increase the air flow. A thorough dust removal was achieved in about three minutes (photo 8).Next I used the blower to dust a vase full of artificial flowers. The wider blower nozzle was used (photo 16). The dusting was a success.I also used the air blower on my desktop keyboard which worked well to remove the hidden stuff between the keys. The air blower was used on my router and cable modem (photo 15) by placing the nozzle on one vent and the dust was blown out of another vent. My next dusting job will be cleaning the inside of my full sized desktop PC. Note: electronics will operate cooler if maintained and kept dust free.Although my primary personal use is for dusting electronics, this blower can be used just about anywhere air is flow needed. Yes, it can blow leaves as shown on the Amazon product page. How practical it is for a very large area is open to debate.**** VACUUM FUNCTION ****The vacuum suction is quite strong considering the size of this tool. The filter is removable for easy cleaning (photo 12). As a test I vacuumed some cracker crumbs ( photo 10) using the crevice tool without any problems (photo 11). This is a small tool, so for larger vacuum job expect to empty the collection reservoir often. As a trade off the crevice tool may do a better job in small tight spaces compared to a larger vac.**** CHARGING ****The included 12 inch USB-A to USB-C charging cable may be a little short depending on where the power source is located. This is about what I expected. Most devices these days include a short cable so I will not ding the blower. If your charging source is a USB-C port just use another charging cable.The power input is 5 volts 2 amps (photo 4) so a common low wattage phone type charger meeting these specs will work just fine. An alternative (slower charge) can be a computer or TV where it is common for its USB port to output 5 volts 1 amp.

it's mostly bark with not much bite. I have another one of these, not this one specifically but another duster and it blows a ridiculous amount of air. Its loud but it gets the job done. This thing has a nice digital readout that tells you battery life and when you turn it on and change speeds it reflects that which is nice. This blowers biggest shortfall is the nozzle isn't tight enough. It can't direct the air very well, I brought it to work to blow out my keyboard and it was not really able to remove any of the dust and dirt from it. Granted it's not very old, in fact it's less than a week old. I have a cat and a dog and I take their hair with me everywhere, and it seemed to struggle to even blow off the hairs that I found on it. It also has a vacuum attachment. I thought oh ok sweet, a small computer vac is never a bad thing except that it can't really create much vacuum. This works better as a blower than a vacuum and it's not great as a blower. It sure does sound like it's going to blow the house down when it's on high speed tho. I mean, does it blow, yeah, its just not very good at it. I suspect that the battery will last a decent while so it can do it for a while before it needs charged again. If the attachment had a smaller orifice to better concentrate the air, I'm sure it would be as good as the other one I have that does have a much smaller nozzle and it blows like mad. I suspect that is the single biggest issue for this little guy.

Fantastic portable fan and boy does it pack a punch! I was “blown away” *pun intended* by how strong the output this mini fan is capable of. It’s got 3 speed levels, each of which are significantly stronger than the previous, and surprisingly isn’t all that audible in terms of noise output. It has 2 “blowing” attachments and one “vacuum/suction” attachment, but I bought this to be an electric version of compressed air. It's great for tough, small, hard to get areas like: keyboards, automotive air vents, even for drying small components whether it be paint or dye. The build quality is excellent and has a solid weight to it. The screen is very intuitive and tells you exactly what setting you're on, and what the battery life is showing a maximum of 4 bars. It can be charged via USB-C and comes with a supplied cable. The packaging is visibly high-quality and this can be given as a gift as the “unveil” or “unboxing” experience has a premium feel.Overall I'm very satisfied, 5/5 stars can recommend!

What a fantastic portable fan this is! My expectations where blown out of the water with this fan. This is the 3rd portable fan I own as they work great for drying off resin models after being washed. It has multiple levels of power. Each are pretty decent but the violent mode is incredible! That's the mode I use the most and the shortcut of holding down the button and it only staying on while you have the button held down is super convenient as I only use it in short bursts. This not only blows air but it also has a vacuum feature. Using the highest setting with the vacuum attachment on works so well! It's great for keyboards or really anything that has small creaves or gabs that a normal vacuum can't reach.The build quality is fantastic as well and has a really good weight to it. The screen is super nice so you know what setting you're on, if the lights on, and what the battery life is at any given time.The packaging is equally as nice and gives that high-quality product feel when opening it.Overall I'm very happy with this portable fan and it works outstandingly for the use case I use it for.I highly recommend this to anyone needing a portable vacuum or blower.
