I have found my Ecoflow unit to be a good value for short outages, limited load situations. (I have a River 2 Pro) It runs my fridge for 8+ hours, and easily charges all our portable electronics many many times. I pull it out long before I even consider starting the generator. They seem to make good stuff.

What Redditors Say

Best praise vs top criticism for Generac Guardian Series

Best Praise
+10 pts
I was picking up one of my children from an event. Another vehicle was nearby and had a blow-out. They were trying to change the tire and frankly nothing was working for them. It was dark and rainy. I had my gloves, my raincoat, and several lights, so I decide to help them. First the jack broke. So I got my jack out and jacked up their vehicle (I guess the jack doesn't count because it was in my vehicle anyway). Then the spare was way low on air. So I got my air compressor out and filled it full of air. However, we could not get the tire off because it was rusted so bad. So we just moved it out of the way for someone to work on it later. Maybe I didn't really help them, but it made me think about what I should have in my vehicle if it happened to me. Honestly, this vehicle was a death trap. The other three tires didn't look so great either. I'm shocked that the parents or guardian would let their child ride around in something that unsafe.
