It makes inflation and deflation quick, easy and convenient for you thanks to the powerful 10.8 V AS 2 battery. This 2-in-1 unit is easy to use and can be used to inflate anything from tyres for your vehicle, ride-on mower or bicycle to air beds, footballs and pool accessories. You can also use it to deflate items like the pool inflatables quickly too. The KOA 20 comes with various attachments and nozzles which are conveniently stored on the tool. It comes fitted with a high-quality brass nozzle on the hose for fast and easy connections. The compressor has an ergonomic design with an integrated LED light at the front of the tool for working in low-light situations. The tool also has a soft grip handle and rubber feet to keep it stationary whilst it’s working. The KOA 20 has a display which is simple to operate and control. By pressing the MODE button you can easily switch between either high-pressure or volume function, depending on what you are inflating. With the plus and minus buttons, you can set the selected target pressure to your desired level and by pressing the UNIT button, you can display the pressure in BAR, PSI or kPA units. You can also activate the LED light by pressing this button. Please note that the KOA 20 has not been designed for use with compressed air tools or to inflate paddle boards. On a fully charged AS 2 battery the KOA 20 has a working time of 23 minutes.
