Review on 🔋 Upgraded Cordless Air Duster for Efficient Computer Keyboard Cleaning | Powerful 41000 RPM, Long-lasting 6000mAh Rechargeable Battery | Type-C Fast Charging | Eco-friendly Alternative to Compressed Air Cans by Josh Sharp

First conclusion: When I received this device, I expected a certain charge level, as with almost all cordless devices. Wrong, it was deader than a doornail. There was no life in it, and I wasn't sure if it was DOA or not. At least I had a chance to test the device's claim that it can be fully charged in 3 hours. It was fully charged in 3 hours and 5 minutes. He passed the litmus test. The included nozzles do not snap into place as expected. You have to push or "squeeze" it into the hole. Operation: You turn it on/off by pressing the orange button where your right thumb should be when holding it. Turn counterclockwise for slower speed and clockwise for faster speed. At its lowest speed, it still blows out a decent amount of air to clean the keyboard. At maximum speed it blows enough air for many tough jobs. I would say it could easily compete with air tanks. It also cleaned easily in my desktop case, including the graphics card. However, be aware that it is VERY LOUD. It actually gets a lot louder than I would prefer for any speed but the slowest. It's worse than a hair dryer because of the high pitched sound. My suggestion: put on your favorite headphones and listen to some music. I tested it with my AirPods Pro (with Active Noise Cancellation enabled) and the noise level was acceptable at 75% of top speed, even with no music playing. My final test was running it on a full charge. At the lowest speed (because it's acceptable air and the least noisy speed) it was still running after 30 minutes. That's way more time than I need for pretty much every single cleaning task. The battery type is Lithium Ion and the device is made in China. Conclusion: While it's a lot harder on the ears than Air Cans, it's definitely better than continuing to buy Air Cans. You also don't have to worry about running out of air tanks, especially during cleaning (or worse, in the middle of the night). Therefore, the purchase is recommended. It gets one star for high noise. If you find my review helpful, please click the Useful button. Thanks very much!
