The Greenworks 40V 16" Brushless Cordless Chainsaw is a powerful and efficient tool designed for homeowners to tackle various yard projects and storm clean-ups. The chainsaw features a 16-inch bar length, which is suitable for medium-sized tasks. The brushless motor enhances its performance by providing more power, longer run-times, and extended motor life, making it a reliable choice for frequent use. Being battery-powered, it eliminates the need for gas, reducing maintenance hassles and environmental impact; however, the power source may limit its performance in very demanding tasks compared to gas-powered alternatives.

The chainsaw weighs approximately 10.4 pounds, which is reasonably lightweight, allowing for easier maneuverability and reduced user fatigue during prolonged use. Safety is prioritized with the inclusion of a chain brake, which minimizes the risk of injury. Additionally, the automatic oiler ensures the bar and chain are kept lubricated for durability and smooth operation. The tool-less tensioning feature simplifies maintenance, making it user-friendly for those who may not be mechanically inclined.

While the push-button start adds to its convenience, users might find the need for frequent battery recharges a minor inconvenience during extended tasks. The Greenworks chainsaw stands out for its ease of use, safety features, and low-maintenance design, making it a solid choice for homeowners looking for a cordless solution.

The ReliaRoads 40V brushless chainsaw offers a solid 16-inch bar suitable for light to medium cutting tasks like pruning trees and cutting firewood. Its brushless motor provides efficient power and longer tool life with less maintenance compared to traditional motors. The chainsaw runs on two 20V DeWalt batteries (not included), giving cordless convenience and decent power without the hassle of gas engines.

Weighing about 10.5 pounds, it balances portability with enough heft for stable cutting. Safety features include rapid chain stop, which quickly halts the chain when the trigger is released, helping reduce the risk of accidents. Maintenance is user-friendly thanks to an automatic oil pump that keeps the chain lubricated for longer use without frequent refills.

The batteries are sold separately, which adds to the initial cost if you don’t already own compatible ones. While the 16-inch bar is versatile for many tasks, it might not be sufficient for heavy-duty cutting or very large trees. This chainsaw is well-suited for homeowners and casual users who want a reliable, easy-to-use cordless saw for general yard work and pruning rather than professional logging or large-scale cutting.
