Saved by the Delta 2
Living in the Tampa Bay area, I have just gone through Hurricane Ian. By luck, I ordered my Econflo Delta 2 on September 22. I arrived today September. I took it to a friend that has power, it was fully charged for about an hour. Right now I have my refrigerator connected, laptop and cell phones charging and pool pump connected. I cannot wait to use the breathing machine tonight for a decent night of sleep finally. I am back to living a normal life, thanks to My Econflow Delta 2. I would recommend this little gadget to anyone. Sis silly if you live in hurricane areas

Game Changer!!
I have only had my Delta 2 for about a week, but it has already been a game-changer for me. It has become central to my quality of life. With 1800w of AC output in such a small and complete package I now can move more freely while maintaining my ability to control my environment. I have severe food allergies and the Delta 2 allows me to take my food preparation on the road with me so that I can insure my food is allergen-free and cooked to my preference.
No more cold, water-logged food on the go. I now have a small refrigerator, induction burner, and water pot in the trunk of my car, or in my SUV. I can pull over at the time and location of my choice and by doing so level out the nutritional intake that curbs the peaks and valleys associated with delayed meals. The Delta 2 is easy to use, has ample charging options, and is rock solid in its performance. Game changer and life changer.

Excellent Batt for the price
So far, it worked as expected. We are using it only for camping and it has exceed our initial thoughts. Planing to get one or two more ( camping and astronomy sessions) and I let you know future results.

Best decision buying the Delta 2
I bought the Delta 2 and it was one of the best decisions I have made. It charges super fast, about an hour, which is really important to me. It has outlet connections, usb and usbc, which is handy when plugging a variety of things in. The Delta 2 has come in handy when the power went out and we were able to use it to run our refrigerator and a couple of other necessary items. The lifting handles come in handy when moving it around.
Additionally, another thing I like is I can keep it stored inside the house and handy in case of emergency when not in use and there is no gas involved with the gas generators. The fact that it is portable is a huge plus. I can’t wait to take this with me next time we go camping!

Excellent product with excellent value.
I’ve only had the Delta 2 for almost a week now, but I’ve tested it out for days with discharge and charge without issue. Fast charged and battery-friendly rate charge were both pretty quick. Total adjustability is a great feature. App is working good with no issues between the app and product.

Light and energy in the darkness around
A year ago, I would never have thought that I might need an alternative power source. But I live in Ukraine and a war has started in my country. Therefore, the availability of electricity during frequent blackouts has become a vital necessity. The ability to continue working when part of the city is in total darkness is what I owe to the Ecoflow Delta 2. I chose this particular model in the first place because of its reliability, stability, and durability. This device has served my family faithfully for almost 3 months. And I am absolutely satisfied with it.

Great power in a small package!
I was lucky enough to be able to pick up my new Ecoflow Delta 2 on Black Friday, the deal was so good and with these specs, it knocks anything comparable to the delta 2 out of the park. I regularly go off-roading and camping, before this I have a GoalZero Yeti 500x (which is only $150 less for a much less capable unit) after getting my domestic fridge and now a diesel heater this winter I found myself needing a bigger unit.
The specs speak for themselves and in a package the size of a small desktop computer I couldn’t be happier with the Delta 2. I also work in construction and we don’t always have readily available electricity to warm up our food… just for fun one day I brought it in and it powered our microwave with no issues!! I was pumped! I highly recommend Delta 2!

I’m surprised and very well pleased, super light
I’m not gonna lie this thing is an absolute game-changer. Want SUPER QUIET? Want SIMPLE? get this thing. It’s beyond super quiet it doesn’t even make a sound so easy to use and super simple. sell your Honda Gas Operated generator and don’t even bother with Harbor Freight Predators etc. Be safe about your health and life get this Delta2. I’m homeless in a van but this Brand Spanking New ECOFLOW DELTA2 is really taking very good care of me.
It is worth the money! This thing was so very well engineered it is so smart and so powerful. I was shocked that I could finally microwave food without having to do it the bum way at 711 cus not even my other SUV or especially this Van could generate enough power to operate this Microwave I have heard even with car engines running JS. So now thanks to ECOFLOW DELTA2 I can sit here and watch movies with surround sound on and play video games charge my phone and stuff like that. And if you’re a stoner you could use it to break up your weed the top is flat and smooth and cleans easily the bottom is very grippy BEAUTIFUL Master Piece. A+ Thank you guys for your commitment to excellence.
So get yours and treat it well so it could last longer. I’m not a paid actor by these guys either or work for them I’m just sharing my experience👌
I even have a heater that I’m gonna turn on right now for a couple of minutes cus it is getting cold so…..and the heater is small and requires a lot of power. I know my other car couldn’t do this but my tiny little ECOFLOW Delta 2 can. Watch 👇 So after about 15 minutes of use I ended up with 99 hours and 58% left on the battery 🔋

I started overlanding a few years ago with an entry-level explorer Jackery 240. It charged my small things fine. I upgraded my rig and got a fridge and diesel heater for winter camping and now I was looking around for alternative generators. After watching a few YouTube videos and a discount later I pulled the trigger on the entry Delta 2. This is a huge game changer because not only do I have more than 4x the battery life, but I also have 4x recharge cycles.
This is because of the LFP batteries. Another great feature to have is the app. When I’m on a hike or in my rooftop tent at night I can glance at my battery storage and that gives me peace of mind. AC charging is a big win with having a 1200w input recharge for about a 1hr. It also sounds like a superjet when all the fans are running. I don’t mind it since I know it’s to keep the unit cool.
I’ve tested this for a few weekend winter camping trips and it’s perfect for a weekend lander that needs to power a fridge, electric stove, phones, blenders, recharge lights, and much much more. It’s been powering my diesel heater for two nights at a time and it’s a champ. Although, I would love to review and use the extended battery pack giving you double the capacity and a solar system to trickle charge when I’m out in the middle of nowhere. I believe the Delta 2 is a great unit for weekend camping. Until another discount comes around I’ll probably hold off for now. I mean unless a company is willing to donate for a review 🙂
