EF ECOFLOWSolar Generator DELTA2 with 220W Solar Panel, LFP(LiFePO4) Battery, Fast Charging, Portable Power Station for Home Backup Power, Camping & RVs

OK. I don't do very many reviews. I was shocked how well the solar panel/ power station worked. I was skeptical about the reverse back solar claim. But in full sun I got 210w. It charged up from 30% to 100% in about 2-3hrs. Chasing the full sun every 40min or so. The panels are a bit heavy and the stands are a bit troublesome. But efficiency makes up for sure. The power station is not magic. It charged up on 110 to from nearly dead to full in 2hrs. Impressive. It powered my 12v fridge for nearly 2days straight without charging. The app is descent and simple. Car or RV camping for sure with this setup. I was offgrid for 4days. No issues. If you are powering a camper fridge, laptop, lights, usb stuff. With the sun you can go indefinitely. I would suggest running your ecoflow powerstation at least 2 times to nearly zero before you go out and rely upon it.

First I want to say that this company needs to win an award for their customer service - a 5 star gold rating; I'd give more stars if I could!I purchased this unit on sale and then just a few days later it went down in price. My order was still being processed and had not shipped yet, and I really wanted the discount, so I contacted ECOFLOW to see if I could just cancel my order and then repurchase at the lower price, or maybe they could they just give me the difference in form of a refund to my credit card. Well that's exactly what they did! No fighting or begging; they just gave me the refund. I also had other questions regarding my new power station and they responded to me the very next day, and sometimes even in the same day. Each time they were helpful and very friendly (Eve, Lila, and Andy - thank you) You can't get better service that that!This is my first time purchasing a power station, and watched several videos on YouTube to see which company made a better unit, and hands down this company won due to their high quality units, and their excellent customer service was mentioned several times. So, I gave them a try and, I'm so glad I did. The unit is working extremally well. I have my new, large patio swamp cooler hooked up to the power station, and I'm using the included solar panels to avoid plugging into the electricity. I find it much more satisfying to watch the sun power my new swamp cooler, and in a few weeks my above ground pool filter, instead of watching my electric bill increase each month during the summer. I'm so happy with my purchase that I've already taken advantage of the current sale to buy a second solar panel to have around just in case I need it down the road. I will not hesitate to purchase form ECOFLOW again when I'm ready to get a larger unit for inside the house due to the power outages that seem to happen more often during the summers.In regards to the solar panel. In researching the power station I learned that many things could affect the intake wattage on your solar panels such as, where you live, the time of day, how intense the sun is, and of course the angle of the solar panels directed at the sun (being off even an inch could make a 5-10w, or more difference in the wattage your are pulling into your power station). In the end, you will likely never see the input advertised no matter which solar panel you purchase. With that in mind, it's currently 8:15am here in Phoenix AZ and my solar panel is pulling in around 175w which I think is pretty good for so early in the morning. Now, I saw another reviewer's comments where he had placed some type of reflector sheet in front, and in back, of his solar panel to try and pull in more watts. So, I thought I'd give that a try. Went out to my car, grabbed my cheep $5 sun reflector screen and placed it in front of my solar panel, and WOW, it went up to 195w. Since my solar panel is one of the Bifacial solar panels I think I might need to purchase something a little better than my $5 car screen so I can take advantage of both sides of my solar panel. I really couldn't be happier with this purchase.

This was my second purchase of the Delta 2 with 220 volt solar panel bundle. Company always replied promptly to any messages that I sent them and they even offered some compensation because of a slight (1 day) delay in delivery, but I declined since it was only 1 day. I love how these systems are modular and there are multiple ways to combine them so that users can buy one system and then add capacity to it with later purchases as finances permit. This is much better than simply having an extremely powerful system that has to be purchased all at once. Additionally, having a modular system such as this allows for redundancy, so that if one part should ever break, then I can still use the remaining parts interchangeably and don't have to replace the entire system. I combined these systems with a low power vehicle refrigerator, small portable hiking water heating kettle, and LED lights to create a system that conserves enough power to keep operating regardless of power outages and can be maintained indefinitely using the solar panels. The quick charging capability using 2 sets of solar panels is a huge help because one of the problems with solar generally, is that you can't assume full sun every day. So with these, even part of the day is more than sufficient. Additionally, since these are BI-FACIAL solar panels, you can boost the input by placing mirrors behind the panels. Amazon sells plastic squares of mirrors that serve this purpose at minimal expense. Overall, very happy with purchase(s) of these products.

This is a very good product, exactly as advertised, and easy to set up. It also saves me from the danger of gasoline powered generators and the aggravation of listening to it chug chug chug. The only problem is that you'll need an extra extension cord to get the solar power to the battery which needs to be bought separately with attention to getting the right cord. You shouldn't leave the generator outside but the panels must be facing the sun, so the extension is necessary. The manufacturer packed and shipped the products very well. It won't power the whole house but I won't do without a cup of coffee and a scrambled egg when the next hurricane comes along.
