Cordless power tools are portable tools that operate on rechargeable batteries instead of being plugged into an electrical outlet. This design allows for greater mobility and convenience, making them ideal for both professional contractors and DIY enthusiasts. Common types of cordless power tools include drills, saws, and impact wrenches, which can be used for various tasks around the home or job site. The batteries used in cordless power tools are typically lithium-ion, providing longer run times and faster charging compared to older battery technologies. Many manufacturers, such as DeWalt, Makita, and Bosch, offer a range of cordless tools that share the same battery platform, allowing users to interchange batteries between different tools for added efficiency.
