With a sales rank of 18,360, it appeals to those who prioritize ease of use and portability.

The compact design weighs only 6 lbs, making it perfect for outdoor activities, including camping.

Overview of the Greenworks 80V 18" Brushless Cordless Chainsaw

The Greenworks 80V 18" Brushless Cordless Chainsaw is available for $246.99 and is geared towards professionals and heavy-duty users. It holds a better sales rank of 7,008, indicating its popularity among those who need a more robust tool for tasks such as tree felling and firewood preparation. With a brushless motor providing 2X more torque, this chainsaw delivers superior performance, allowing for up to 150 cuts on 4x4 lumber on a single charge. Its automatic oiler and easy adjust tensioning features further enhance its productivity.

Performance Comparison

The performance of the Greenworks 80V 18" Brushless Cordless Chainsaw significantly outshines that of the 40V 12" model. While the 40V chainsaw provides about 50 cuts on 4x4" treated wood per charge, the 80V variant can manage up to 150 cuts on the same lumber size, demonstrating its superior efficiency. The enhanced brushless motor technology in the 80V model allows for longer runtime and quieter operation, making it suitable for more demanding tasks. For users who frequently tackle larger jobs, the increased power and cutting capacity of the 80V chainsaw are clear advantages.

Weight and Portability

The Greenworks 40V 12" Cordless Compact Chainsaw is significantly lighter at just 6 lbs compared to the 80V model, which, while not specified, is generally heavier due to its larger battery and motor. This characteristic makes the 40V chainsaw more portable and easier to handle, especially for those who may not be experienced with power tools. The lightweight design reduces fatigue during extended use, making it an excellent choice for outdoor or camping situations where mobility is key. Conversely, the added weight of the 80V chainsaw may be less desirable for casual users but provides stability and performance for more serious applications.

Safety Features

Safety is a crucial consideration when selecting a chainsaw, and both models prioritize user protection. The Greenworks 40V chainsaw includes a dual safety start mechanism (lock + trigger) that prevents accidental starts, ensuring safer operation. The tool-free auto-tensioning feature also contributes to user safety by allowing quick adjustments without the need for additional tools. The 80V model offers similar safety features, including easy adjust tensioning for maintenance, but places a stronger emphasis on professional use, which often entails higher risks. For novice users, the 40V model’s lightweight and user-friendly operation may be more appealing.

Battery and Runtime

When it comes to battery performance, the Greenworks 80V 18" Brushless Cordless Chainsaw boasts a more powerful lithium-ion system, providing greater runtime and efficiency for demanding tasks. In contrast, the 40V model includes a 2.0Ah battery that is suitable for lighter jobs and casual use. The 80V chainsaw's ability to provide up to 150 cuts on 4x4 lumber indicates a substantial advantage for users who require high performance and longevity during extended work sessions. The 40V model may suffice for small-scale projects but may not hold up during more extensive operations.

Price Comparison

The Greenworks 40V 12" Cordless Compact Chainsaw is priced at $159.99, making it about 35% cheaper than the Greenworks 80V 18" Brushless Cordless Chainsaw, which retails for $246.99. This price difference reflects the target market for each product; the 40V model is designed for casual users, while the 80V model is aimed at professionals seeking high performance. While the lower price of the 40V chainsaw may attract budget-conscious buyers, those needing robust capabilities may find the investment in the 80V chainsaw worthwhile.

Which should you buy?

Ultimately, the decision between the Greenworks 40V 12" Cordless Compact Chainsaw and the Greenworks 80V 18" Brushless Cordless Chainsaw hinges on your specific needs. If you are a casual user focused on portability and ease of use for light tasks like pruning and storm clean-up, the 40V model at $159.99 is an excellent choice. However, if you require a powerful tool for professional applications such as tree felling or extensive firewood cutting, the Greenworks 80V chainsaw, with its advanced features and greater cutting capacity, is worth the investment at $246.99.
