Compressed Air Duster, Electronic Air Duster, Portable 45000 RPM Cordless Dust Blower, 6000mAh Battery Air Can Duster, Powerful Computer Keyboard Cleaning Air Spray, Rechargeable Electric Canned Air

Works wonders for keyboards that have more depth to it and not as flat as laptop keyboards. Overall very nice for getting rid of dust and not just on keyboards. With long battery as well its great.

Works great since air in a cans are getting harder to come by and getting more expensive. Saves lots of money.

I like that this duster is super easy use. No 5692 settings with complicated butons, just a simple squeeze on. I wanted to replicate the functionality of canned air. Could be a bit stronger.

I used to buy anhydrous compressed air for cleaning my vacuum cleaner's dust bin and filter. Expensive.I would not suggest using it to blow off your computer's motherboard. The keyboard would be fair game.Charging is easy but the battery lasts a long time.

Using canned air is inconvenient, wasteful, and expensive. I was curious about how an electric air duster would compare. It turns out that this product is actually much more versatile than canned air.My first test was blowing out the debris from several keyboards and then following up with canned air, which didn't blow out any additional dust or debris. There are several very noticeable differences between the blower and canned air. The electric blower moves a LOT more air. This makes for quicker dusting. It can be used in any orientation whereas canned air must be held upright or else you get that freezing spray out the straw. The electric blower is great for dusting larger objects and the underside of things, holding the blower sideways or upside-down. Another advantage is that you can blow air continuously instead of using canned air in brief spurts. This came in handy when blowing dust out of my electrostatic furnace air filters. I got more dust out of the filters with the blower even after I cleaned them with a vacuum. I also used the blower to dust some furniture tops and sculptured art and it performed well. Sometimes with canned air, I'm concerned about accidentally damaging things with the freezing spray.I was surprised by how long the charge lasted. The device came with a (fully?) charged battery and I used it for maybe 15 full minutes before it ran out. About 30 seconds before the charge runs out, the blower slows down, and then it shuts off. You can still get a few more pulses out of it after it shuts off. This is the behavior I was hoping for, rather than gradually slowing down over several minutes. Basically, you get full-strength blowing until you have to recharge it again. The charger is well designed in that the light on the charger is red when it's charging and green when it's charged (or not connected to the unit).I haven't used the electric blower for drying, yet, but it could definitely be used to dry the inside of narrow-necked bottles after washing.The blower feels good in your hand, has good build quality, feels sturdy, and the button has good action.

Push the button, it's on. Let the button go, it's off. All the other ones with multi-speeds you have to push the button a few times to get to high speed, then hold the button to turn it off. That might be fine if you're dusting the wings of a jet plane, but I like the quick on (max speed) then off when I let go. Much easier than multi-tapping the button.

It didn't have the power I needed for it to blow dust out of my phone. Maybe it would blow dust off of flat surfaces but not really built up dust like a compressed air can.

I bought this to be able to stop buying canned air (& having to throw away the pressurized can afterwards) all the time. I have found this is so useful for so many other things besides cleaning computer equipment and it lasts a long time between charges. I love this and highly recommend it
