Cordless electric duster with adjustable four-speed motor, USB-C charging and a built-in Li-ion battery. Includes three nozzle attachments and an LED indicator, designed to replace canned compressed air for routine maintenance.
Precise dust removal, with 4 adjustable speed modes
A high-speed motor delivers roughly 31,000; 50,000; 70,000 and 100,000 RPM, selectable by pressing the control. Rapid concentrated airflow dislodges dust from narrow gaps, keycaps and circuit-board crevices.
Targeted bursts remove trapped debris without needing to dismantle devices, and lower speeds reduce risk on delicate components.
Reusable and energy-efficient cleaning, with built-in Li-ion battery and USB-C charging
Integrated Li-ion battery provides around 30 to 40 minutes of continuous operation per charge and charges via the supplied USB-C cable. Start-up requires a long press and a gentle press cycles the speed.
Regular maintenance becomes cheaper and greener than buying single-use cans, while common USB-C chargers and power banks keep the unit topped up easily.
Multipurpose household use, with three nozzle attachments and LED indicator
Three nozzle types change the airflow pattern for narrow gaps, broader surfaces or light inflation, and an LED helps illuminate dim areas during cleaning. The ergonomic form and simple switch control aid one-handed operation.
Useful beyond electronics for inflating air beds, clearing window tracks and helping with camping tasks, while the LED ensures confident cleaning in shadowed corners.
