KOA 20 Cordless Air Compressor

The KOA 20 battery-powered air compressor is the ideal tool for quick and easy inflation and deflation of air beds, tyres, balls and even pool inflatables. It uses our AS 2 battery, which is interchangeable with all of the other tools in the STIHL AS System, including the GTA 26 pruner, ASA 20 powered secateurs and HSA 26 shrub shears.   

The high-quality brass nozzle is easy to connect and the integrated LED light on the front of the unit gives you extra visibility even when light levels are lower. The display on the tool is easy to operate too; the MODE button allows you to switch between different functions and set the target pressure quickly. By pressing the UNIT button, you can also display the pressure in BAR, PSI or kPA units.  

The hose and nozzles can be stored on the tool and the compact design means it can be tucked away neatly when not in use. 

• Working time on a full battery charge: up to 23 minutes

Please note that the KOA 20 is not designed for use with compressed air tools or to inflate paddle boards. 

Features

Digital display

The display on the top of the machine makes it really easy to use and shows all the key information, including the current battery level.  

Integrated LED lights

The integrated light is a really useful feature in low-light situations, for example, when inflating a bike tyre off-road. The switch is easy to access on the display. 

Compact storage

The hose wraps round the unit neatly and the nozzles are stored on the unit itself so the KOA 20 can be stored neatly in the garage or shed. 

Constant power

Like all STIHL battery tools, the KOA 20 delivers constant power right to the end of the battery charge, thanks to the intelligent electronics.
