Electric chainsaw in the test: kindling with a powerful ego

Dhe customers of battery-operated tools – there are more and more – can be divided into two groups: Some buy a nameless product at the discounter or in the hardware store and are happy with it because they rarely use it anyway. The others have higher demands and dig deeper into their pockets for a well-known brand. In addition to the desire to get a minimum of quality for this, the plan often plays a role later to purchase additional devices that the battery will fit. Well-known products are a better choice in many cases, especially if they are harshly used, such as chainsaws. Those that professionals also use then have much more reserves.

At this point, the objection often comes that no forest worker cuts oaks with an electric saw. That’s right, at least we don’t know anyone. But there are also horticultural companies and arborists who appreciate the light, quiet and easy-to-use cordless tools. There are several copies in the author’s private collection, the heavy chainsaw is hardly used anymore. The vehicle fleet has been supplemented by an Ego ES 1800 for a few weeks; this year it has sawn together around two solid cubic meters and a few very interesting features.

Ego who? The name was previously unknown to us, which can mean an educational gap, according to its own admission, Ego is the world’s largest provider of cordless outdoor tools. The Chinese company called Chervon has been building products for well-known brands for nearly three decades, and the group includes, for example, Flex and Skil. Under the own brand Ego, cordless tools are sold exclusively through specialist retailers, it is aimed at discerning customers and has only been on the market for a few years with today’s standard range from lawnmowers to leaf blowers to multifunctional devices.

Unusual chain tensioner: when the cover is tightened, the saw does this automatically.

The batteries have it all, and they are also unusual from the outside with their curved shape instead of the brick that is otherwise used. This increases the surface area and is used for cooling, because heat generation is the neuralgic point of highly stressed lithium cells. Those do not come from China, but from Samsung in Korea, they are also coated with a material that absorbs heat. Ego confidently calls its batteries the most powerful on the market, 14 of them connected in series produce 56 volts (at the nominal voltage of 3.6 V per cell it would be 50.4) and 140 watt hours for the smallest power storage device, the largest has four layers and With 560 Wh, it is probably the most powerful battery for hand-operated devices at the moment, but with 3.4 kilos it is also a real chunk that is better carried on the back and supplies the tools from there using an adapter, there are also large backpack batteries.

For the chainsaw, we therefore prefer the medium size of 5.0 Ah and 2.2 kilos in weight, together with the cleanly made ES 1800 saw you have around 7 kilos in your hand. It is inserted crosswise under the handle, which makes the ensemble a little wider than competing products. That didn’t bother us at work and results in a balanced weight distribution. The ES 1800 is the largest of the three saws in the range, it has a unique tensioning mechanism for the chain: an eccentric with an internal slip clutch pushes the sword forward until a defined chain tension is achieved, then the clutch slips while the screw is on the big one Turning wheel is tightened further. This works very well, to re-tighten the cover fastening is simply loosened and tightened again. A sword from Oregon with a 3/8 × 1.1 chain is used, both commercially available, the automatic is matched to the standard sword length of 45 centimeters, 40 is still possible. We also like the transparent oil tank, through which you can guess the oil level. With the 5 Ah battery you can work for about three quarters of an hour, then the oil tank is half empty. Charging on the voluminous quick charger takes a little shorter with considerable noise from the fan. 80 percent is achieved in half an hour, so with two batteries the saw is always ready for use.

How does it look like that? The Ego is one of the most powerful cordless saws we’ve had in hand, and there are quite a few. It runs smoothly and radically, as usual for this species, however, the user must not exert too much pressure, otherwise the engine will stop. With the ES 1800 this happens without any significant transition, the speed can hardly be throttled down. Then it feels like half a second before the saw responds to commands again. Despite several hours of intensive work, only interrupted by the laying of wood, we were unable to overload the chainsaw to such an extent that it would have needed a break to cool down. A ring of LEDs on the battery shows the charge status. When it is nearing the end, the engine’s performance does not decrease, it then suddenly stops. A nice detail is the illuminated saw cut for working in the twilight, the bright LEDs start at the push of a button.

The saw and energy pack are convincing, the price is a challenge to the established brands. Almost 300 euros for the saw, 100 for the charger and 250 for the battery with 5 Ah, the 10 Ah battery would be something for strong people, it costs around 500 euros. One can look forward to the further development of the product range, for example a mobile voltage converter is to come in the new year with which 230 volts alternating current can be drawn from the batteries.
