Deep Cleaning & Wide Application: This duster leads the market with its ability to produce a powerful push of air at nearly 10 times the speed of sound (28 m/s) for deep cleaning of microscopic dust. This small duster can clean everything from printed circuit boards to computers, electronic instruments, medical equipment, and many other areas where a standard wiper or duster couldn’t. High Reusability & Easy Charging: Large built-in 6000mAh lithium batteries provide nearly 30 minutes of continuous use each charge. Its ability to be charged using a USB port makes it ideal for long periods of use. The ordinary gas dusters had to be abandoned after a few usage due to a damaged bag. In comparison, this electric duster is extremely reusable.
