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 cant wait to take this with me next time we go camping!

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.

Delta 2

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 alternatives 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 over more then 4x the battery life, but I also have 4x the recharge cycles. This is because of the LFP batteries. Another great feature to have is the app. When Im on a hike or in my roof top tent at night I can glance at my battery storage and that gives me peace in mind. AC charging is a big win with having a 1200w input recharge about an 1hr. It also sounds like a super jet when all the fans are running. I dont mind it since I know its to keep the unit cool. Ive tested this for a few weekend winter camping trips and its perfect for a weekend lander that needs to power a fridge, electric stove, phones, blenders, recharge lights, and much much more. Its been powering my diesel heater for two nights at a time and its 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 Im out in the middle of no where. I believe the Delta 2 is a great unit for weekend camping. Until another discount comes around Ill probably hold off for now. I mean unless a company is willing to donate for a review :)

Great power in a small package

I was lucky enough to be able to pickup my new Ecoflow Delta 2 on Black Friday, the deal was so good and with these specs it knocks any thing 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 dometic 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 couldnt be happier with the Delta 2. I also work in construction and we dont 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 the Delta 2!
