The Power and the Glory

In our guide to choosing the best cordless chainsaw, we consider everything from chain lubrication to left-handed use. However, arguably the most crucial factor is the method of power. Our shortlisted products are all electric, which we believe is more practical than petrol. Petrol-powered chainsaws tend to be more powerful, but few of us are going to be chopping down oak trees. For everyone else, the lack of engine priming and cord-pulling is hugely beneficial.

Our shortlisted chainsaws have modular batteries, which you can share with other products in the manufacturers’ ranges. This design means you can access more batteries than those supplied with each product – ideal if you’re undertaking a job requiring a considerable amount of cutting. Batteries can take up to five hours to fully recharge, though a quick half-hour top-up will restore much of their power.


Safety First, Safety Second

Chainsaws are just one of many products capable of cutting, sawing and slicing. Depending on the nature of the work involved, you might be better off using a less powerful (and less dangerous) member of the saw family. Our guide to 21 types of saws may be of assistance if a chainsaw seems overkill.

Chainsaws are uniquely dangerous, and correct usage is critical. This YouTube guide to using and maintaining a cordless chainsaw should keep you safe. 

Our shortlisted products all have handguards, while the BLACK+DECKER has a two-switch activation mechanism, and the WORX switches off by pushing the hand-guard forward.


Weight and See

Any chainsaw is a heavy object, and strapping on battery packs further increases their bulk. The BLACK+DECKER has one side-mounted battery, while the WORX balances out with one on either side of its main motor shaft. However, Greenworks takes the best approach by positioning its motor vertically – making this the most practical chainsaw for left-handed users.

If weight is an issue, it’s worth noting that the WORX weighs more than the other two products combined. It may be the most powerful, with the longest chain, but it’ll tire your arms quicker as well. We’d recommend picking it up and holding it in different positions before committing to a purchase.


Oil be Blowed

All three shortlisted products have integral chain oiling systems, though they differ considerably. The WORX and Greenworks have automatic chain lubrication, helping to reduce heat and prolong the life of the chain. 

The BLACK+DECKER has a semi-automatic mechanism, while its 53ml oil tank capacity is less than half its competitors. This smaller tank helps keep weight down but means you’ll be topping it up more frequently. 

Admittedly, users of electric chainsaws tend to call on their devices relatively infrequently compared to corded or petrol-powered ones, so this shouldn’t be a significant drawback to the BLACK+DECKER model.


Best Cordless Chainsaw UK – The Top 3

These are our picks as the best cordless chainsaws currently available, starting with a product on the cutting edge of heavy-duty slicing and dicing.

1. Greenworks G40CS30K2

Greenworks Cordless Chainsaw G40CS30K2 (Li-Ion 40 V, chain speed 4.2 m/s, 30 cm Guide Bar Length, 120 ml Oil Tank Capacity, All-around Handle with 2 Ah Battery & Charger)
  • EASY TO START: Insert the 40 V batteries & get started: with the cordless chain saw you can immediately cut branches and small trees freely & without cables – 2 Ah battery & charger are included
  • RELIABLE: Greenworks cordless chainsaw has a chain speed of 4.2 m/s, a 30 cm long guide bar and an automatic chain oiling mechanism – garden work is no longer a problem
  • SAFETY: The electric start button and the additional hand guard provide more safety while you are working: in addition, the chain replacing and tensioning can be done without tools
  • COMFORT: Greenworks cordless chainsaw ensures a pleasant and safe working in the garden thanks to the bow handle for different handle positions as well as the ergonomic rubberized soft handle
  • ONE BATTERY FOR ALL: the Greenworks 40 V batteries from 2 Ah to powerful 6Ah are versatile & compatible with many Greenworks products in the garden and workshop range

Opting for a lime green chassis finish (in contrast to the orange hues of our other shortlisted devices), Greenworks have produced a chainsaw that houses its motor vertically instead of horizontally. This clever design makes the G40CS30K2 more comfortable for two-handed operation, with weight evenly distributed between the rubberised bow handguard and the bottom trigger grip.

A 40V battery provides a chain speed of 4.3 m/s, while the 30cm blade can run for up to half an hour at a time. The batteries have LED charge-remaining lights and are be hot-swappable with other Greenworks products for extra versatility. A full charge of a 4Ah battery takes two hours.

Weighing 2.75 kg, this is a convenient product, with no tools required for chain tensioning or replacement. There’s an oil level indicator, while automatic lubrication should extend the chain’s lifespan.

ProsCons
Can run for 30 minutes at a timeRestricted visibility due to the vertical motor housing
Lightweight and balancedNot the longest or most powerful saw in our tests
Powerful motor and quick battery recharging 

2. WORX WG384E

Sale
WORX WG384E 36V (40V Max) Dual Battery Cordless 35cm Brushless Chainsaw
  • Dual 20V batteries for extra power and longer run time
  • Brushless motor provides higher power, extended run time, and longer battery life
  • Tool-less chain replacement system
  • Part of the WORX power Share battery platform allowing you to interchange your batteries with your other 20V WORX tools.

While the BLACK+DECKER opts for 18V power, WORX has equipped their entry into our shortlist with up to 40V of power. Packing a 35cm blade, this is the most imposing product on our shortlist, though it’s also by far the heaviest. 

Many of the specifications are shared across our shortlist, such as the tool-free chain replacement and tensioning system. 

The WG384E has automatic oil lubrication with a level indicator, while WORX has engineered out kickback as far as possible. As with both the Greenworks and BLACK+DECKER, you can swap batteries from other products in the WORX range to keep the WG384E going beyond its runtime.

A chain brake stops the blade in a fraction of a second, which is reassuring when you consider the chain speed can reach up to 8m/s. This chainsaw might be a heavy piece of equipment, but it’s also extremely powerful – by far the most industrial product on our list. So if you’re planning to chop down trees rather than sawing logs, this is the product for you.

ProsCons
Unparalleled chain length and speedBy far the most expensive product we tested
Extremely powerfulIt may be too heavy for some people to use
Chain brake boosts safety 

3. BLACK+DECKER GKC1825L20-GB

Sale
BLACK+DECKER GKC1825L20-GB 18v Chainsaw-25cm, 18 V, Orange
  • A lightweight and cordless chainsaw with 25 cm cutting width - ideal for logging, pruning, reducing windfall, preparing firewood and other general DIY maintenance tasks
  • Weighing only 3.1 kg with the weight evenly balanced between handle and the cutting bar
  • Secondary bale handle with cover offer better handling and control during the application; the handle cover offers additional protection
  • Tool-free tensioning provides quick and simple chain fitting and adjustment
  • Powered with 2.0 Ah lithium-ion battery offering approximately 220 x 3.5 cm cuts per battery charge

The first thing you notice about BLACK+DECKER’s contribution to our shortlist is the side-mounted battery pack. This design, combined with the left-handed support handle, makes it less balanced than the Greenworks. In particular, left-handed users may find the GKC1825L20-GB cumbersome to use.

That aside, there’s lots to like about the awkwardly-named GKC1825L20. It mirrors the Greenworks’ tool-free tensioning and chain fitting while improving it by offering an anti-kickback chain and two-switch activation. 

The over-moulded rubber grip is quite tactile, and it doesn’t obscure the operator’s view of the chain as the Greenworks does.

The 25cm blade isn’t the longest on test here, though the 3.1kg weight of the GKC makes it marginally the lightest product we tested – ideal for people with limited upper-body strength. It is down on chain speed compared to its rivals, delivering 3.5 m/s, while its oil system is semi-automatic and requires a button to activate. 

ProsCons
Lock-off safety switchNot ideally suited to left-handed users
A smaller blade makes it wieldyDown on power compared to other products
Excellent mid-job visibility 

Final Thoughts

It’s relatively easy to award the BLACK+DECKER our bronze medal in this competition as it doesn’t lead the field in any area. It’s down on length, power and run-time compared to both competitors, and that lopsided design means it’s not the easiest to use, nor is it the cheapest item we tested. However, it’s slightly lighter than the Greenworks, and less than half the weight of the beefy WORX, making this an excellent product for beginners and anyone lacking well-defined biceps.

If you regularly undertake heavy-duty cutting but don’t want a mains-powered or petrol chainsaw, the WORX is your best option. 

Its huge 35cm blade and 8m/s chain speed make this the ideal option for slicing through hardwood, and the 40V batteries have impressive longevity. However, it’s heavier than our other two candidates combined, and also much more expensive.

That leaves the Greenworks as a worthy test winner. It does everything well, outperforming its rivals in several critical areas. As a result, this is a compelling product for most buyers, especially anyone with other Greenworks products reliant on its 40V battery pack. The fact it’s also the most affordable chainsaw on test is merely the cherry on top of the cake.
