However, corded sanders require access to a power outlet, limiting their portability and maneuverability.
Cordless sanders, on the other hand, offer greater freedom of movement and are ideal for projects in remote locations or where power outlets are not readily available. Modern cordless sanders, equipped with high-capacity lithium-ion batteries, provide ample power for most sanding tasks. However, their runtime is limited by battery life, and you may need to purchase additional batteries or pause to recharge them. The choice between corded and cordless depends on your specific needs and priorities. If consistent power and heavy-duty performance are essential, a corded sander is the better choice. If portability and convenience are more important, a cordless sander offers greater flexibility.
