Power tools are important for any job site. Power tools that are electric, gas powered or popular cordless power tools help to get any job done right.
Cordless power tools contain a rechargable battery which varies in voltages - either 7.2 volt, 12 volt, 14.4 volt or 18 volt. Batteries can be standard or Lithium-ion, which hold their charge longer. The higher the voltage, the heavier the battery... usually. The Lithium-ion batteries weigh less, so along with their longer charge, Lithium-ion batteries are the most popular type of battery for a cordless power tool.
If you buy cordless power tools by the same manufacturer, there's often an advantage in that they use the same rechargable batteries, so you have more batteries available to charge up from other cordless power tools that you may not be using at the moment for a particular construction or remodeling project.
The most popular type of cordless power tool is the cordless drill. Cordless drills have different size drives - 3/8 inch, 1/4 inch or 1/2 inch.
