Seesii 8 inch mini chainsaw review: the short verdict

A mini chainsaw has one core job: cut branches fast without the weight and noise of a full-size saw. The Seesii does that as an 8-inch tool-only saw: the 800W brushless motor and manganese steel chain are the performance story, the automatic oiler and one-hand 2.6 lb design are the convenience story, and extension-pole compatibility extends the reach. The gaps are the missing battery and the absence of any stated warranty.

The saw

The PS800 is an 8-inch cordless mini chainsaw built for pruning and light cutting. The listing states an 800W brushless motor driving a manganese steel chain, with a maker claim of cutting 8-inch logs in 12 seconds, and notes the 8-inch bar doubles the cutting area of a 4-inch saw. The automatic oiler feeds from a 30ml tank with a press bulb, so there is no manual oiling between cuts. At 2.6 lb with an anti-slip grip and one-hand design, it is aimed at pruning hedges, trimming overhead branches and processing small timber. The head is compatible with an extension pole for high limbs. What is in the box is the mini chainsaw only: no battery, no charger.

For firewood, the honest framing is kindling and branches, not rounds. An 8-inch bar handles limbs and small logs; splitting and bucking full rounds is full-size saw work. The 12-second cut claim is the maker’s, not a measured figure, so treat it as marketing until you try it.

What the PS800 does well

The power-to-weight story is strong: 800W brushless in a 2.6 lb saw is the reason to buy a mini saw over a manual pruner. The automatic oiler with a 30ml tank is a real convenience feature that cheaper mini saws skip. Extension-pole compatibility means high branches without a ladder. The one-hand design with anti-slip grip suits quick pruning sessions.

Limitations

Tool only is the big one: the listing states no battery or charger is included, so the price you see is not the price you pay if you own no compatible battery. No warranty term is stated anywhere in the listing. The 8-inch bar limits the work to branches and small logs; this is not a firewood-bucking saw. And the 12-second cut claim is unverified marketing, so do not buy on that number alone.

How we scored it

We scored the PS800 on cutting performance, build, value, safety features and warranty, from the listing figures. It scores on the 800W motor, the 8-inch bar and the oiler; it loses on the missing battery and the missing warranty term.

Who should buy the Seesii 8 inch mini chainsaw, and who should skip it

Buy it if you prune branches and process small timber, you already own a compatible battery, and you want the lightest powered option with an automatic oiler. The extension-pole compatibility is a plus for high limbs.

Skip it if you need to buck full-size firewood rounds, if you own no compatible battery, or if you want a stated warranty term. For bigger cutting, see our mini chainsaws for firewood guide.

Safety and gear

A mini chainsaw still throws a chain at speed: wear eye protection and gloves, keep a firm grip with the work clear of the bar, and never cut overhead without the pole attachment and stable footing. Keep the chain oiled and tensioned; a dry chain is a dangerous chain.

Buying advice: batteries, bars and realistic expectations

Budget for the battery

The listing states this is the tool only, with no battery or charger included. Before buying, check which battery platform the PS800 uses and whether you own it; if not, price the battery and charger alongside the saw. A cheap tool-only saw plus a new battery and charger can cost more than a kit from another brand. The 800W brushless motor will draw hard on a small pack, so a higher-capacity battery means longer sessions between swaps.

What 8 inches actually cuts

The bar is 8 inches, which sets the work: branches, limbs, kindling and small logs. The listing claims 8-inch logs in 12 seconds, but that is the maker’s marketing, not a measured figure, and it assumes a sharp chain, a full battery and soft wood. Hardwood, a dull chain or a low battery all slow the cut. For bucking full-size firewood rounds, an 8-inch bar is the wrong tool; that work belongs to a full-size saw. For pruning and storm cleanup, 8 inches is plenty.

The oiler is a real advantage

The automatic oiler with its 30ml tank is the feature that separates this saw from cheaper mini saws that need manual oiling. Chain oil matters: a dry chain cuts slower, wears faster and is more likely to kick back. Fill the 30ml tank before each session with proper bar oil, and check the level when you swap batteries. The press bulb primes the system, so use it after refilling.

Extension poles extend the saw, not the safety rules

The head is compatible with an extension pole per the listing, which puts high branches in reach without a ladder. A pole-mounted saw is harder to control than a handheld one: the 2.6 lb saw plus the pole’s leverage means fatigue comes fast, and a falling branch has further to drop. Cut small sections, keep the work area clear, and never cut directly overhead where the branch can fall on you.

Chain care decides the experience

The manganese steel chain is only as good as its edge. Mini saw chains dull fast in dirty bark, and a dull chain makes the motor work harder while cutting slower. Learn to sharpen or keep a spare chain on hand; the listing does not state a spare is included. Check tension before each use: a new chain stretches, and a loose chain derails. The 17.32 by 13.4 by 3.94 inch saw stores easily in a tool bag between sessions.

Ask about the warranty

No warranty term is stated anywhere in the listing. For a battery-powered tool with a brushless motor and electronics, ask the seller what coverage exists before you buy. A stated term on the motor and battery platform is worth more than a vague promise, especially on a tool-only purchase where you are already buying into the battery system.

Frequently Asked Questions

Does it come with a battery?

No. The listing states this is the tool only; the battery and charger are not included.

How big a log can it cut?

The bar is 8 inches, and the maker claims 8-inch logs in 12 seconds. That claim is unverified; treat the saw as a branch and small-log tool.

Does it oil the chain automatically?

Yes. The listing states an automatic oiling system with a 30ml tank and a press bulb.

Can it reach high branches?

The head is compatible with an extension pole per the listing, though the pole is not stated as included.

Does it have a warranty?

No warranty term is stated in the listing. Ask the seller before you buy if coverage matters to you.
