I just went electric for my lawn tools. I looked into what was out there, and went with the EGO brand; 56V.
My 45 year old Poulan 16" chainsaw had finally just plain wore out. My 30 year old inherited string trimmer is still in pretty good shape, but I figured if I was going to get a new saw, I might as well bite the bullet and start fresh.
So I got a 16" electric saw, a string trimmer, and a leaf blower, something I've never had before.
I like these new gadgets. No more dicking with premix gas or stale gas, and now I just grab a battery and go. They all perform better than I expected.
I also picked up an EGO 400W inverter which uses the same batteries. I live in the boonies and power outages are becoming a lot more common. The inverter can run my desktop, or small appliances. In testing it I was surprised at how long it can run things. This gives me a "buffer" option, before I fuel up and fire up the generator if the outage looks like it's to be a long one. I don't know that I'll get one, but there is a solar panel available for this set up.
So all of those are EGO brand, and all run the same 56V batteries. I'm big into "commonality". Tools using the same battery; vehicles sharing the same parts; and firearms using a few common calibers.
I run Bosch 18V power hand tools. I recently also picked up several work lights that use the same Bosch battery as my tools. That's the lighting that I'll use for power outages.
I a set up a dedicated storage space for my chargers and batteries in the pantry room where I keep my emergency water and other blackout supplies (extra flashlights, candles, radio, hand cleaner, rough-service cooking utensils, etc..).
I also gathered up, and went through, all of my AA and D cell flashlights, and converted them to run LED bulbs instead of incandescent. A few small lights are placed around the house (bedside, in the crapper, the kitchen, and at the doors), with the extra lights and the battery supply stored in my pantry room.
The only thing that I still need to get, is an LP gas camp stove, to make cooking easier during an extended outage, and I'm looking at units that can combine cooking and heating functions.
I like how well that battery tools work these days, and I'm well stocked with just two rechargeable battery types, 18V and 56V, and with single use batteries. I'm well stocked with other emergency supplies, and it's all organized now.
I'm better prepared for power loss, or other emergencies, than I've ever been, and it's a really great thing for just the peace of mind that it brings.
