I just received my Delta 1300. The build quality is excellent. It's operation is intuitive. I was able to charge it from 29% to 100% fully charged in approximately an hour. I like the protective bag that came with it but I do wish that it had an attached pouch to hold the cords. Overall I would rate it as excellent.

So far so good. Excellent customer service, got through right away to a real person due to a fault on my part in the ordering process. They even called me back with an update'?very happy with quality of products. Plugged Delta in and charged within 39 min. 160 w solar panel gave me 98 watts just sitting on a chair on my patio. The true test will be when I take it up tent camping in the mountains this weekend but I have no doubt it will perform splendidly!

I bought two Delta 1300s about six months ago and decied to add one more. The fast charging time (on AC) was a key feature for my initial purchase. I am using them for power outages and they works great. I found that this new unit has a much quieter fan, reducing the noise level substantially. That's another plus for the Delta.

I could not be happier with my purchase of the EcoFlow DELTA. I have three other solar generator from three different companies and the slow speed of their charging and low peak surge is why I was looking for a different solution. I bought this unit for power outages, I do not care about total battery life cycles. I want fast charging from solar with enough power to manage all my cooking needs.

Fantastic machinery, well built! I love how it can back up my Tesla with several miles while on the road, can become a life saver! Definitely looking forward to testing it out fully I think computers and refrigerators are most important in a home, and maybe garage door. ;) Overall, great heavy duty craftsmanship and a game changer 'cause of its power and versatility. I don't think Gial Zero can compare, their thing is heavier and huge and more costly

We bought it to use when camping and it works well. It runs a tea kettle or 750W microwave with our Alpicool T36 refrigerator. We had no problems charging from the car or solar panels. An unexpected bonus is that it will power my electric chain saw, leaf blower or hedge trimmer so I can use them anywhere on our 1 acre property without running long extension cords. We have not had it long enough to assess durability and reliability but it seems to be well made.

If you go in with eyes open, and in an appropriate use-case, the Delta is a terrific power station. In DC mode it is silent, but whenever the AC mode is turned on the fans run (noise, which varies depending on load and can get noticeably loud). The DC-AC inverter isn't as efficient as some. Finally, if one forgets to turn off AC mode when not needed, there is about a 20w/hour drain. Where the Delta really shines is in DC mode. I have a simple camping rig in my pickup's camper. The Delta silently powers a DC compressor fridge, charges my cell phone, tablet and other items as needed. Used this way, the Delta 1300 can run for 2+ days without needing a charge. It's also nice to have the powerful AC inverter to run just about any power tool, even a microwave, should the need arise (in which case noise isn't an issue). A *HUGE* plus of the Delta is the incredibly fast charging time, whether on AC or via solar. While in Florida this winter I pulled out my Delta and plugged it into a garage's outlet (after asking permission, of course). In the 20 minutes it took to change the oil, the Delta charged nearly 40%! I have since purchased two semi-flexible 50W solar panels, which I pull out when stopped at destinations. These easily keep up with my energy demands. On the rare occasion there are multiple-days of cloudy weather, the Delta's relatively light weight and sturdy built-in handles make it easy to carry someplace and quickly top up using a wall plug. The Delta is lightweight and compact for its capabilities, well made, and stylish. It is a superb DC power device that charges incredibly quickly. I ding it one star for the AC inverter inefficiency and noise, but, given the appropriate use case, this isn't a problem. Highly recommended!

It charged up the battery last night and used it today. Battery was at 100%, I use it on my fridge and after 3 1/2 hours the battery was down to 36%. Everything works great. I recharged the battery again in only 45 minutes. Only thing I would changed would a way to add more batteries.. So far it a Great solar generator !!!

This is an update to my original review I made back in 2021. I have been really impressed with my Delta except with the true AC capacity. The most I ever got was around 786Wh or 62% of the promised 1260Wh. I finally decided to reach out to the support team. Cassie reached back out instructing me to discharge and recharge the unit twice. I did that with no improvement, so they sent me a label to send the unit back. They sent out a semi new unit and I tested it and was shocked when I pulled 1224Wh or 97%. Now the fan is much quieter with normal use and seems to run only when needed. Overall, the Delta has everything I would need in a power station, but it unfortunately predates the app support my River Max has, that I find very useful. I was very surprised at how awesome the support team was. It’s nice to buy something with the confidence that the company will stand behind their product. EcoFlow is one of those companies based on my experience.

I did a lot of research and your product seemed to offer the biggest bang for the buck. I like the display screen and the fast recharge time. It's not terribly heavy so that my wife could handle it if I'm not home. As it's brand new the only factor I don't know about is the battery life, I'll let you know in a few years
