Electric Cordless Air Duster - 40000 RPM Portable Air Blower 6000mAh Compressed Air Duster Alternative to Air Can Gas Cleaning for Keyboard Laptop PC Camera Cleaner

It's about as strong as you blowing air with your mouth. Only difference is, it doesn't run out of breath.

canned air doesn't go the distance and datavacs are just overkill for blowing out a keyboard or PC case. this thing is perfect for that. I also use this to clean out the filters for my vacuums. works perfect for that as well. battery life isn't great, but I'm not filling up an inflatable house, so it's just 'fine/good enough'

​I bought this electric air duster to finally stop wasting money on disposable compressed air cans, and overall, it is a really solid device. The build quality is excellent—it feels sturdy, well-made, and comfortable to hold in your hand without feeling like cheap plastic. Another massive plus is the battery life. A single charge lasts a surprisingly long time, giving you plenty of juice to clear out multiple keyboards, PC towers, and desk setups before needing to plug it back in. ​My only real critique is the blowing power. While it easily clears away loose dust, crumbs, and daily debris, the pressure isn't quite as intense as a fresh can of traditional compressed air. If you are trying to blast away heavy, caked-on dust that has been stuck inside a fan for months, you might wish it had just a little more raw pressure to get the job done quickly. ​That being said, for an eco-friendly, rechargeable alternative, it is a fantastic tool that saves you money in the long run. Highly recommended for regular maintenance and everyday cleaning

Not as powerful and canned air but close

Very strong and blows pretty hard and last a good while. Could use a light of or hard to see areas but still overall amazing product.
