These DEWALT combo kits feature powerful cordless tools that run on 20V batteriesideal for demanding jobs in construction, maintenance, and home improvement. Tools powered by 20V batteries deliver more torque compared to lower-voltage options, making them a great choice for tougher tasks. While they may be slightly heavier, they offer the strength and performance needed for a wide range of applications. Kits may include batteries with different capacities (measured in amp-hours, or Ah): lower-capacity batteries are lighter and more compact, while higher-capacity ones run longer between charges.
