I ordered this air duster for cleaning my PC case and other electronics. The first setting is gentle and good for cleaning the fans and dust filters.
Fully charged the item is 102000 rpms but 90000 rpms is the actual operating speed which is more than enough to get the job done. With the small attachment it's stronger than a brand-new can of compressed air. Do the math, 6 uses and it pays for itself. The vacuum is very strong also with great suction. It cleaned out more dust from underneath my keyboard keys than I even thought was there. The price is comparable to other brands at the 90000 rpm speeds without a battery gauge. It does exactly as expected. Charges to a full charge in about 3 hours. After the initial charge it takes about 15 minutes to top it off from 85% to 100% again. Which is the same amount of Time I ran it for. 15 minutes to clean my whole desktop computer and keyboard. It works that good.
Small, lightweight, great assortment of attachments to clean tight areas. Stronger current than cans of air. Doesn't leave an odor in the air or on the surface of items cleaned. Cheaper then buying cans of air over and over.
Blows well while attaching the two different blowing wands to the back side (red) fan side. Sucks as a vacuum cleaner for couches, hard to reach indoor car corners, or cleaning a tablecloth. Use brush head for sucking cloth.
