What type of tool is a Porta -Power(R)? battery-powered __ hydraulic __ electric __ pneumatic

## Step 1<br />The Porta-Power(R) is a type of tool that is powered by a hydraulic mechanism. This means that it uses a hydraulic system to generate power. <br /><br />## Step 2<br />Hydraulic systems operate on the principle of fluid mechanics, where a small amount of force applied at one point can generate a large amount of force at another point. This is due to the incompressibility of the fluid used in the system.<br /><br />## Step 3<br />The Porta-Power(R) is not powered by electricity, air (pneumatic), or any other means. It specifically uses a hydraulic mechanism to function.
