Compact electric duster for keyboards and PCs
The Rosewill electric air duster spins at 200000RPM with four adjustable gears to blast dust from tight keyboard gaps, PC cases, car seats and other hard-to-reach areas. Weighing .52 pounds, it includes four nozzles for different cleaning tasks and replaces disposable compressed-air cans. A built-in LED and LCD display shows remaining power so you know when to recharge.
Battery runtime and charging
A 4000mAh battery delivers up to 140 minutes of use on the lowest gear and recharges fully in 3.5 hours via the supplied cable. The unit draws 20 Amps during operation and requires a 5V 2A adapter that is not included. If the battery becomes hot, wait ten minutes before recharging as a safety precaution.
Cordless freedom for indoor and outdoor use
No hose or outlet is needed while cleaning, so you can move between a desktop, a sofa, an air-conditioner vent or a barbecue grill without restriction. The ABS plastic housing resists wear and electricity, and the package provides only the duster, four nozzles and a charging cable — plan for a separate 5V 2A power source to keep it running.

Questions about this item
How do I charge the 4000mAh battery and what is the one step users often miss?
Use a 5V/2A adapter (not included) with the supplied cable for a 3.5-hour charge. The step many miss: wait 10 minutes before recharging if the unit feels hot, as the safety circuit blocks charging until it cools.
What part will need replacement first with regular use?
The built-in 4000mAh lithium-ion battery is the only consumable; after several hundred cycles its capacity drops and the 140-minute runtime shortens. The ABS housing and 200,000 RPM motor have no user-serviceable wear items.
At which gear does the 200,000 RPM motor hit its thermal limit first during continuous operation?
Gear 4 (maximum speed) draws the full 20 A and generates the most heat, so the internal protection will throttle or shut off the motor soonest on that setting during sustained use.
