Sun Joe Handheld Mini Chainsaw | Compact Cordless Power
Our handheld mini chainsaw combines professional-grade cutting performance with the portability you need for jobs around the yard. Weighing just 2.6 pounds with the battery installed, this compact tool slices through branches up to 4 inches in diameter without the bulk or weight of traditional chainsaws.
The 4-inch Oregon cutting bar and chain deliver smooth, efficient cuts whether you’re pruning overgrown shrubs, clearing storm debris, or tackling light firewood prep. Powered by our 24V rechargeable battery system, you get up to 40 minutes of runtime per charge with zero emissions, zero gas mixing, and zero pull-cord frustration.
We built the tool housing from impact-resistant polymer that stands up to drops and bumps while keeping the overall weight down. The ergonomic handle includes a safety trigger lock and textured grip zones so you maintain full control even when working overhead or at awkward angles.
What makes this mini chainsaw stand out
Battery power that goes the distance
The 24-volt lithium-ion battery system powers through typical pruning sessions without running out mid-job. On a full charge, you can expect 35-40 minutes of active cutting time, which translates to roughly 100-120 cuts through 2-3 inch branches under normal conditions.
The included charger brings a depleted battery back to full capacity in about 90 minutes. We designed the battery with smart charge protection to prevent overcharging and extend overall lifespan. The same battery works across our entire 24V tool lineup, so if you already own other Sun Joe cordless equipment, you can swap batteries between tools.
Oregon bar and chain engineering
We equipped this mini chainsaw with a genuine Oregon 4-inch guide bar and low-kickback chain, the same components professional arborists trust on full-size equipment. The compact bar length gives you excellent maneuverability in tight spaces between branches while still providing enough reach to handle overhead cuts without a ladder.
The chain runs at an optimized speed that balances cutting efficiency with battery life. You’ll notice smoother performance compared to cheaper mini saws that overdrive the chain and burn through power. The automatic oiler feeds a steady drip of bar oil to the chain during operation, reducing friction and heat buildup that would otherwise dull the edge.
What’s included in the box
Your Sun Joe mini chainsaw ships as a complete ready-to-cut kit. You get the chainsaw body with installed 4-inch bar and chain, one 24V 2.0Ah lithium-ion battery, a wall charger with indicator light, a snap-on blade guard for safe storage, a 100ml bottle of bar and chain oil to get you started, and a quick-start guide with safety instructions.
We also include a hex wrench for occasional deeper maintenance, though the tool-free chain tensioner handles most adjustments. The blade guard snaps over the bar and chain when the saw is not in use, protecting both the chain edge and preventing accidental contact during transport or storage.

Common questions about the Sun Joe mini chainsaw
The 4-inch guide bar handles branches up to 4 inches in diameter effectively. For the best performance and cleanest cuts, we recommend staying in the 2-3 inch range for most pruning work. You can tackle 3.5-4 inch material, but it requires more time and multiple passes.
Branches thicker than 4 inches are technically possible by cutting from different angles, but at that point you’ll get better results and efficiency from a larger chainsaw with an 8-inch or 10-inch bar.
The included 24V 2.0Ah battery provides 35-40 minutes of active cutting time under typical conditions. That runtime translates to approximately 100-120 cuts through 2-3 inch branches.
Actual runtime varies based on wood density, branch diameter, and how aggressively you cut. Hardwoods like oak drain the battery faster than softer woods like pine. The battery recharges fully in about 90 minutes.
No, this is a fully cordless electric chainsaw that runs on a rechargeable lithium-ion battery. There’s no gas, no oil mixing, and no exhaust fumes. The only oil you need is standard bar and chain oil for the automatic oiling system that lubricates the chain during operation.
You simply charge the battery, fill the small oil reservoir, and you’re ready to cut. It’s significantly cleaner and more convenient than gas-powered models.
Yes, but with limitations based on the size of wood you’re processing. This mini chainsaw works well for cutting kindling and splitting small branches for campfire wood. If you’re processing logs that are 4 inches or less in diameter, it handles that task.
For serious firewood production with larger logs, you’ll want a bigger chainsaw with more bar length and power. Think of this tool as ideal for light firewood prep rather than your primary wood-cutting solution.
The tool-free chain tensioning system makes adjustments simple without any wrenches. There’s a knob on the side of the housing that you turn to tighten or loosen the chain as needed. You should check tension before each use and adjust if the chain sags away from the bar.
The automatic oiler handles lubrication during cutting, so your main maintenance tasks are keeping the oil reservoir filled, checking chain tension, and occasionally cleaning sawdust from the housing. The chain is a standard Oregon replacement that’s widely available when you eventually need a new one.
The saw includes a dual-trigger safety lock system that requires you to press both the safety button and main trigger simultaneously before the chain moves. This prevents accidental starts if you bump the trigger while carrying the tool.
The low-kickback Oregon chain reduces the risk of the bar jumping back toward you during cutting. When you release either trigger, the chain stops within a fraction of a second. We also include a blade guard that covers the bar and chain during storage and transport.
Yes, the 24V battery system is compatible across our entire line of 24-volt cordless tools. If you own other Sun Joe 24V equipment like hedge trimmers, leaf blowers, or string trimmers, you can swap batteries between them.
This cross-compatibility means you can build a complete cordless yard tool collection without needing separate batteries and chargers for each tool. Many customers invest in additional batteries to keep one charging while another is in use.
