I have an electric leaf blower my mom gave me, and I have a ryobi gas leaf blower.
The electric leaf blower is kinda cool, the battery holds enough charge to blow the grass away after i mow my lawn. But I never use it.
My gas blower is about twice as strong, and I mow yards for a living, so the one yard charge thing just wouldnt cut it. And even if it did, because it only blows half as strong, it'll struggle on more amounts of debris.
So, I'll say this, if you're using it on just your yard, and you don't wait til your grass is real tall and leaves a lot of debris, it'll work just fine, which is cool cause u dont have to mess with gas n mixing.
