What does "cordless" mean in relation to power tools?

The definition of "cordless" in relation to power tools refers to tools that operate using rechargeable batteries instead of being plugged into an electrical outlet. This design offers significant advantages in terms of mobility and convenience, allowing users to operate the tools in various locations without the restriction of a power cord. Cordless tools are especially beneficial for outdoor use or in spaces where electrical outlets are not readily available. Additionally, advancements in battery technology have enhanced the performance and runtime of cordless tools, making them a preferred choice for many users.

Other choices do not accurately represent the primary characteristic of cordless tools. For example, the idea that cordless tools can only be used outdoors limits their versatility, and stating that they lack an on/off switch is misleading as most power tools—whether cordless or corded—include an on/off mechanism for safe operation. The notion that cordless tools are always lighter than corded versions can vary depending on the specific models and designs in question.
