FXAFXA Brushless Electric Chainsaw 12" Cordless vs DEMIMA Mini Chainsaw for Miwaukee Battery,

Design and build quality

The FXAFXA Brushless Electric Chainsaw is constructed with a focus on durability and ergonomic handling. It weighs 5 lbs, which provides a balance between stability and maneuverability for garden tasks. The design includes a high 13m/s chain speed intended for efficient cutting. In contrast, the DEMIMA Mini Chainsaw emphasizes a compact form factor suitable for pruning flowerbed branches or cutting logs. It features a tool-free chain tensioning system and a bar lock knob, making it easy to install and replace the chain. Both units utilize brushless motor technology, which generally contributes to longer tool life and reduced maintenance requirements compared to brushed alternatives.

Motor and power performance

Power output is a key differentiator between these two models. The FXAFXA unit is equipped with a 1000W pure copper brushless motor. This specification suggests a higher capacity for handling denser wood and preventing jamming during operation. The DEMIMA model utilizes an 800W brushless motor with a specified speed of 32000 rpm. While the RPM figure indicates rapid chain movement, the lower wattage suggests it is optimized for lighter duty cycles. The FXAFXA motor is described as preventing jamming, which is critical for consistent performance in varying wood conditions.

Cutting capacity and bar length

Cutting capacity is determined largely by the guide bar length. The FXAFXA comes with a 12-inch bar, allowing it to handle larger diameter logs and branches. It includes two 12-inch chains in the package. The DEMIMA offers a 2-in-1 design featuring both 8-inch and 6-inch chains. This dual-specification combination provides flexibility for users who need to switch between fine pruning and slightly heavier cutting. However, the maximum cutting diameter on the DEMIMA is limited to 8 inches, whereas the FXAFXA can accommodate larger material up to 12 inches.

Battery compatibility and usage

Both chainsaws are sold as tool-only units, requiring the user to supply their own battery and charger. The FXAFXA is compatible with Dewalt 20V and 60V batteries, including models such as DCB204, DCB205, and DCB606. This wide voltage compatibility allows users to leverage higher capacity batteries for extended runtime. The DEMIMA is designed for compatibility with Miwaukee M18 batteries, such as the 48-11-1820 and 48-11-1852. This makes it a suitable addition for users already invested in the Milwaukee ecosystem. Neither tool includes a battery, so overall runtime depends on the specific battery pack utilized by the owner.

Safety features and operation

Safety mechanisms are integrated into both designs to prevent accidental injury. The FXAFXA includes an ergonomic safety lock that prevents accidental starts, ensuring the tool only operates when intentionally engaged. It also features a double nut design for stable guide plate fixing. The DEMIMA includes built-in low voltage protection to eliminate safety hazards associated with battery depletion. Both models feature tool-free chain tension adjustment, which reduces the risk of injury during maintenance by eliminating the need for additional tools to tighten the chain.

Accessories and maintenance

Maintenance requirements are minimized by the inclusion of specific features. The FXAFXA includes an automatic oiler system with a pure copper oil pump that lubricates the chain during use, reducing wear and ensuring smooth cutting. The package also includes a storage bag, gloves, two 12-inch chains, and a protective cover. The DEMIMA highlights easy access chain tensioners for quick adjustments but does not specify an automatic oiling system or included accessories in the provided data. The inclusion of gloves and extra chains with the FXAFXA adds immediate value and readiness for use out of the box.

Price and overall value

Price is a significant factor for budget-conscious buyers. The DEMIMA Mini Chainsaw is listed at $55.99, making it the more affordable option. The FXAFXA is priced at $75.99, reflecting its higher power output and additional included accessories. When evaluating value, the FXAFXA offers more hardware including the automatic oiler and extra chains, which might offset the higher initial cost over time. The DEMIMA provides a lower entry point for users who already possess compatible M18 batteries and require a tool for lighter pruning tasks.

Which one should you buy?

Your choice depends on the scale of your projects and existing battery ecosystem. If you need to cut larger logs up to 12 inches and prefer a tool with an automatic oiler and more included accessories, the FXAFXA is the superior choice despite the higher price. It offers greater power with its 1000W motor. If you prioritize cost savings, already own Milwaukee M18 batteries, and primarily need a tool for pruning branches up to 8 inches, the DEMIMA provides sufficient performance at a lower price point. Both tools offer brushless efficiency, but the FXAFXA is better suited for heavier garden tasks.
