So Far, Very Good

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.

Worked perfectly for Starlink Mini and Macbook Pro in the field! What a great setup!

I bought this specifically to run a Starlink Mini antenna and a Macbook Pro (64G/4T) in the field. The Starlink Mini and Macbook Pro only drew between 20 and 70 watts. The solar panel kept it fully charged basically, even unto late in the day, it was at %98 at the end of the day, which was around 8:30PM. On the second day of use, I didn't hook up the solar panel. I used it from 8:30AM until 4:30PM and had %86 left in the battery. So, for my purpose, this was a %100 successful setup. If you do the arithmetic, if I can run for 8 hours on %14 battery draw, that means I could run 56 hours before drawing down the battery. FYI, I did find a carrying strap that works with this, it's the same strap I use for my small tower computer. I couldn't find any carrying straps that said they worked with the EcoFlow, and I already had this one...so decided to try it. That worked perfectly too!The only recommendation I would have is for the USB-C port to support the new PD mode that allows it to directly power higher voltages out of the USB-C, which would make it be able to power the Starlink Mini directly with no adapter. But, the adapter is certainly not a problem with SIX power outlets on the back! So, no harm, no foul on that one.

App needs work

Only issue I really have is during the day I would like it to use solar over pulling power from AC but unless you completely disconnect it from AC it will not do that and I get enough Sun during the day that would charge this up I already contacted them and they said that's how it is basically I think it would be an easy fix with the app just to tell it when it's not getting enough power from the Sun or let me choose hours that it does not pull AC so I can use the battery

It holds its charge for Months.

I haven't had to use it yet and have had it about 5 months, but it was easy to figure out and set up as I'm an old lady. I check the charge every couple of weeks and it still shows 99% charged. I put it on a small plastic dolly with wheels so I can move it around easily. It appears durable and was well priced.
