Combination kits come with two or more cordless power tools that may be used for a variety of activities. They also come with at least one battery to power the tools, a charger to keep the battery charged, and a storage bag or case to keep the kit's components in. Kits reduce the need to select tools separately and assure that the equipment, battery, and charger are all compatible. They're frequently utilized to provide cordless tools to new team members. Because cordless tools are powered by batteries, they are more portable than corded equipment and can be used when a wired power source is not available. They use brand-specific batteries that are compatible with a variety of instruments from the same manufacturer that have the same voltage and battery series.
