Brushless Compressed Air Duster, 3 Gear Adjustable, Super Wind Power K&F Concept

Podrobný popis

The K&F Concept Brushless Compressed Air Duster is a rechargeable, portable alternative to canned air, featuring a 7,500 mAh battery for 20–40 min runtime, 3 adjustable wind gears, Type-C fast charging (3–4 hours), LED display for battery/gear status, integrated LED light for dark areas, and 3 shaped hard brushes for stubborn stains—ideal for deep-cleaning computers, keyboards, cars, and home surfaces in a lightweight 279 g, with storage bag.

The K&F Concept Brushless Compressed Air Duster serves as an eco-friendly, reusable substitute for disposable compressed air cans, powered by a high-capacity 7,500 mAh lithium-ion battery that delivers 20–40 minutes of continuous operation across 3 adjustable wind gears (low/medium/high, up to 100,000 RPM motor speed for 120 m/s airflow), enabling efficient removal of dust, debris, and particles from electronics, automotive vents, and household crevices without chemical residues or ozone depletion. Fast Type-C charging (5V/2A input, full charge in 3–4 hours) includes multi-layer protections—over-temperature cutoff (>60°C), over-current limit (2.5A max), and short-circuit safeguards—for safe, reliable use. A high-definition LED display provides real-time battery percentage and gear indicators, while a built-in front-facing LED light (100 lumens) illuminates shadowed areas for precise cleaning in low-visibility spots like PC internals or car dashboards. Operating at <50 dB noise level, it's versatile for home offices, vehicles, or outdoor maintenance, reducing waste and costs over time while maintaining tool-free, one-handed operation.
