Cordless Air Duster for Indoor Maintenance

This cordless air duster delivers 41000RPM motor speed for cleaning computers, keyboards, sofas, cars and other electronic devices. It replaces disposable canned air with a rechargeable handheld blower suited for regular indoor maintenance tasks.

Stepless Speed Control and Wind Range

A rotary switch provides stepless adjustment between .5 and 2.47 ounces of wind force. The battery lasts three hours at minimum speed, while maximum output handles stubborn dust but reduces runtime.

USB Charging and Portability

The built-in battery charges via a 10W USB connection using a 2A adapter not included in the package. At .69lb the unit is compact for storage and carry, though users needing continuous high-output operation may find the runtime limiting.

Questions about this item

Will the 41000RPM motor damage sensitive keyboard switches or older motherboard components?

The stepless rotary switch lets you dial airflow from .5 to 2.47 OZ, so you can use the gentlest setting for delicate switches and vintage boards.

How do I verify the duster is delivering full 41000RPM performance after charging?

At maximum rotary position the airflow reaches 2.47 OZ and the motor audibly spins at its highest pitch; a steady blast at that level confirms full speed.

Does the box include the 2A adapter for 10W fast charging or must I buy it separately?

The 2A adapter is not included; the duster ships with a USB cable only, so you will need a compatible 2A charger for the fastest recharge.
