Portable air compressor

A portable air compressor comprising:

• an electric battery;
• an electric motor powered by the electric battery;
• a piston coupled to and driven by the electric motor, the piston configured to compress air within a piston cylinder;
• and
• an air hose having a first end attachable to an air outlet of the piston cylinder and a second end attachable to an inflatable object, the portable air compressor configured to inflate the inflatable object to a target air pressure;
• wherein the portable air compressor is configured to determine when the target air pressure is below a predetermined pressure threshold, and based on a determination that the target air pressure is below the predetermined pressure threshold, inflate the inflatable object at a first inflation rate;
• and
• wherein the portable air compressor is further configured to determine when the target air pressure is above the predetermined pressure threshold, and based on a determination that the target air pressure is above the predetermined pressure threshold, inflate the inflatable object at a second inflation rate greater than the first inflation rate.
