It's here! All the jokes about 'modding' a battery saw may be coming true!

18 inch bar, 3/8 (low pro?, standard?) chain, 2.0 Ah battery, weight (?) - $349 with battery and charger.
They claim it is equivalent to a 42cc gas chainsaw. Does 80 volts give it 2x the torque of a 40 volt saw? More speed? Longer or shorter battery life?

I had seen that one earlier but it slipped my mind about posting it. Thanks.

says, cuts are about same amount.
When comparing actual use cutting torque
Over 150 cuts through 4x4 pressure treated pine performed during a single battery charge
30% more torque
Features
80V Li-Ion System takes the lead in highest and most powerful gas-free cordless system
Capable of 150+ cuts with fully charged 2.0 Ah battery*
Gas comparable delivering 2.7HP, equivalent to a 42cc gas powered chainsaw
Digital controlled brushless motor for more torque, quiet operation, and longer life
Steel bucking spikes and durable metal wrap around handle
Electronic chain brake for safe operation

The brushless motors is what most of the better cordless tools, including contractor type tools, are going towards.
I suppose that pressure treated pine might be a uniform media for test cuts, but we all know that we use different saws for construction lumber and trees. It would be nice to try it side-by-side with other chainsaws: battery, corded, and gas, in more firewood sized/type wood to see what it's capabilities are, and how it stacks up.
From the photos, it looks similar to the Ryobi saws - wonder if they have some common design or manufacturing heritage.
The chain in the photos really looks strange. I was trying to zoom in to see if they used low pro or full sized 3/8 pitch chain, and it almost looks like the reduced kickback bumpers on the tie straps are mounted backwards!
Would love to try it. Interested to see if others follow suit.

Interesting.

If they get it up to 120 volts, maybe it will also come with a cord?

They'd have to have a transformer or rectifier for you to run a 120V DC saw on 120V AC house current.

There you go throwing logic and science at me.
How large/heavy would a 120 volt AC to DC inverter be for something like this?

Hmmm......
Not sure. It'd have to handle far more current than the usual transformers we see for charging and powering DC appliances with AC house current. Gotta ask somebody who's in the industry. Barneyrb comes to mind. He's here IIRC. He's on SH too.
I do know that what we're talking about here (converting AC to DC) would be called a transformer or rectifier. A device that converts DC to AC is an inverter. That's pretty much the limit of my electrical knowledge in this case...

Some great feedback and info.
Well, I spent 45 minutes cutting up a downed tree this evening with the GreenWorks Pro 80v with the little 2ah battery. Thoroughly impressed. It died at 45 minutes, and that's all I can really ask for. It is 90% the speed of my gasser and between cuts I can easily speak to the other folks pulling branches and spotting. I'm very happy with it!
Gas saw he compared to was echo 400.
14.6 pounds as verified on my scale
ready to cut
$250 for the saw, battery and charger. That's the 2ah battery.
When doing research for older farmer local I found this out = Stihl even bought a large percentage of Greenworks in 2016, just to use their motor and battery tech in their electric tools.
