Inverter - how large to charge electric chainsaw?

[ramblinChet]

I am considering purchasing an electric chainsaw in the future and am curious as to what size inverter would be required to charge the saw while driving.

I am considering the ECHO DCS-5000 (56 Vdc) with a 5.0 Ah battery so I guess I am at 280 Wh?

Recharge time for standard charger is 2.50 hours. So 280 Wh times 2.50 h equals 112 W so a minimum 112 watt inverter?

Recharge time for the rapid charger is 1.25 hours. So 280 Wh times 1.25 h equals 350 W so a minimum 350 watt inverter?

As you can tell from above - I am blind when it comes to electrical issues so please feel free to help me answer this question prior to me purchasing an inverter. Thank you!

I have a 18" EGO with a 5Ah battery. The 210w charger was too slow so I bought the 550W. I use a 600W inverter for it. I always bring my Sily1000 because the battery for that saw last for days.

I use the EGO when on my dirt bike. In the truck I take a gas saw that I run on Aspen "green" fuel

If you look at the label on the back of the charger it will have the wattage rating. Find an inverter that has a bit of an overhead on that number and you’ll be good.

Since it sounds like you haven't bought the saw yet it may be worth mentioning many of the major electric tool manufacturers sell car chargers (cig plug style) for their lower voltage batteries (18v, 20v, etc) .

I thought the same thing. I frequently reference such information just out of curiosity. Right now, sitting on my kitchen counter, is the charger for my 40v Kobalt batteries that feed my chain saw. Instead of the typical V/W/Hz, it has a QR code decal. Scanning the decal brings up info for ladies'...uh...massagers. I have no good reason why I don't already own a Kill-A-Watt. I am that level of nerd.

Same batteries?
