As the name suggests, offroad air compressors are designed for use in offroad vehicles. They are typically smaller and more compact than traditional air compressors, making them ideal for use in tight spaces. Offroad air compressors typically have a higher PSI rating than their traditional counterparts, making them ideal for inflating tires and other objects quickly. Many offroad air compressors also come with a built-in light, making them perfect for use in dark or dimly lit areas.
