The better battery powered snow blowers work well. Ego makes a good quality, two stage unit that uses 2ea 7.5AH batteries. It's power compares well to a gas powered snow blower. It's size, maneuverability and weight is better than a comparable gas snowblower. It's run times does not compare well at all, and that's the big problem. If you can't do the job in 10-13 minutes, don't get a battery powered snow blower.
Note: A spare set (the Ego uses two) 7.5AH batteries will run well north of $800!
My PA property has a single driveway about 200 feet long. The neighbors Ego can't do the job with a foot of snow.
The antique Ariens can do it on one tank.
