What Redditors Say
Best praise vs top criticism for EcoFlow DELTA Max
“I bought a cheapo off Amazon to see how it would work for me. I use it to run my cpap when I’m camping and can get about 2 solid nights of use. I really loved the design of the ecoflo and recently upgraded. To the delta max. It’s not cheap but I would recommend. I bought a refurbished unit on a major sale. I have some portable bi facial panels but usually just charge on a wall outlet right now. They make a great little unit to charge that installs in your vehicle. I have the ability to expand and add more batteries. My buddy just got the Anker Solix and we will be testing that this weekend.”
What Redditors Say
Best praise vs top criticism for Generac Guardian Series
“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.”
