Style: DELTA 2 Max+220W Solar Panel
I've read a LOT of reviews, watched a LOT of Youtube videos and had given the purchase of a solar generator (actually, it's just a big rechargeable battery) a LOT of thought. I won't go into all the specs and technical junk since a lot of the other reviewers have done all that. I will just try and briefly discuss What I think about it. I spent around $1,700 for it but that included a big 200 watt solar panel. I see now that the whole package has even gone down a couple hundred dollars to around $1.500 but I still think I got a pretty good deal. I'm a 66 year old female and though both the battery and solar panels are heavy, I can still move them to where I want them. It's summer time here in the Deep South so I laid the solar panel flat on the ground where strong sunlight could shine on it. I had to move the battery fairly close to the panels since the connection cords are only so long, however I set it on a garden stand up off the ground and covered it with a white reflective towel to keep it from getting hot. The color of the battery is dark grey and will absorb a lot of heat if left out uncovered. And for crying out loud, don't forget about it and leave it out in the rain, or it will be ruined. My battery was at 38% charge when unpacked from the box it was shipped in. After 2 days of being charged by the solar panel (and with adjustments made for the movement of the earth and sun) it got to 76% charge. I like having the option to charge it by use of solar panels (and you can connect 2 of them at the same time but I only used the one it came with), but I hope I don't have to use them very often, since it's not a very efficient way to charge it. I charged it the rest of the way to 100% using a household outlet. I chose this particular solar generator (battery) because of the many high reviews, the price, and an output of 2400 watts will power a LOT of things such as refrigerators, freezers, a washing machine, coffee pots, microwave and all the smaller electronics and crap one thinks they'll need if the power should go off for several days. BUT!!! It won't power big appliances for more than 2 or 3 days before needing recharging. That's where the gas generator really comes in handy. It can be used just long enough to recharge the solar battery then shut off to save gas. That's my plan anyway if it should come to it. I think having both a solar generator and a gas/propane generator is the best way to do it as long as you have enough fuel. I connected my now fully charged solar battery to a mini fridge and it stayed nice and cold for 3 days until I disconnected the fridge and plugged it back into a regular outlet. I learned that if you're going to store the battery long term, that it needs to be at 50% or slightly less of a charge to keep the battery safe from self-damage. I don't know the details about why it needs to be at a lower charge, but whatever. The digital readouts are easy to see, it can be connected by an app to your phone, which would be nice in case you needed to see how things were going at the ol' homestead while you were out foraging for berries and non-poisonous mushrooms. But wait! If there's been an EMP then nothing will work anywa................! I suggest learning how to build a Faraday cage and storing your expensive battery in it when it's not needed. The solar panels are huge. Good luck figuring out how to keep them from getting melted if the bombs fall or the sun belches out a big one in our direction. But, you can only do what you can do...... So far, I really like my big battery. I have absolutely nothing negative to say about it. If it should fail for some reason I will be here to update this review even before you hear the sonic boom I created getting here. Oh yeah! I forgot to mention shipping. The battery took about a week after ordering to arrive and it was very well packaged. The solar panel was shipped separately and took about another week (two weeks after initial order) to arrive in very good condition. I chose to purchase it through Amazon because I'm very familiar with Amazon and it was several hundred dollars cheaper than if I bought it directly from Ecoflow. And shipping is free with Prime.

Style: DELTA 2 Max 2048Wh
Llevo usando el EcoFlow Delta 2 Max por unas semanas y hasta ahora ha superado mis expectativas. Lo compré principalmente para emergencias eléctricas y para alimentar algunos equipos durante salidas al aire libre, y cumple perfectamente su función. La capacidad de batería es impresionante. Pude alimentar un refrigerador pequeño, cargar varios dispositivos y usar una laptop sin problemas por varias horas. Lo mejor es la carga rápida: en menos de 2 horas ya está al 100%, lo cual es muy conveniente si tienes acceso limitado a electricidad. El diseño es robusto y fácil de transportar, aunque algo pesado, como era de esperarse con esta capacidad. Los puertos están bien distribuidos y la app de EcoFlow facilita mucho el monitoreo y control del equipo desde el celular. Un punto a favor es que es silencioso en comparación con un generador a gasolina. También se agradece que sea compatible con paneles solares para mayor autonomía. En resumen, es una inversión fuerte, pero vale cada centavo si buscas una fuente de energía confiable, portátil y moderna. Lo recomiendo especialmente para prepararse ante cortes de energía o para quienes hacen camping o viven en zonas rurales.

Style: DELTA 2 Max+220W Solar Panel
So far, so good. Delta 2 plus 220w panels arrived in good working condition. Initial charge of LiFePo4 battery bank went on schedule at 115 AC - and solar panels were set-up in sunlight to check for specification output. All on track. Ops checks good. Campout planned next week, and will put it all to the test. I report more as I use the unit. As of now, I have little more than a basic check run and inventory to report. I’ll be back.

I did quite a bit of research prior to purchasing this item. A year ago the retail price was about $1900, now you can pick them up for 1000. Was so impressed with the first one that I bought another a week later. Combined with two small Honda 2000 W generators, this will pretty much power my entire house in the event of a long-term power outage. Total of $4000 versus $14,000 for a whole house natural gas generator.
