EF ECOFLOWSolar Generators, DELTA 2 Portable Power Station with 2PCS 100W 12V Solar Panels, 1024Wh LFP Battery, Fast Charging, Power Station for Home Backup, Camping&RVs

I recently used this setup for the first time while boondocking with my teardrop camper, and it was a fantastic experience. It provided ample power to run my electric cooler, lights, and TV throughout the night, and it fully charged during the day as we drove to our next destination. The solar panels performed well, although they are a bit cumbersome to pack since they don’t fold. However, I was aware of this beforehand, so it didn’t impact my overall satisfaction. The system is incredibly easy to set up, taking just about 5 minutes. Overall, it’s a reliable and efficient choice for off-grid camping.

I wish I had not waited so long. I originally purchased this unit for off-grid amateur radio operations. It works very well for that purpose. But recent storm related outages allowed this unit to really demonstrate its capabilities. The unit paid for itself when it kept my fridge and freezer running during a recent outage. This unit is reasonably light, very portable, can handle a variety of tasks (charging cell phones, computers, running coffee makers, fridges, and freezers, and even driving my tankless water heater. The first day I recharged it using my gasoline generator. It recharged quickly. The next day I was able to deploy the solar panels (the panels can recharge the system in a couple of hours in very good conditions). At one point, the panels were actually recharging the unit while powering a fridge. Impressive. I love that charge-through capability. I wish the cables for the solar panel connections were longer. And I wish an anchoring system for the solar panels was provided (the light panels are great, but are very unstable in windy conditions). While I still have and use gasoline generators, this is my go-to generator for all kinds of projects. I'm pleased I purchased it and am planning to buy another one this year.

I love my Delta 2! Works great for my camper snd my pickup. I can carry it around and take with me. And I like that it has several ways to charge! I want to purchase another for my tiny house.

The 220w solar panels often produce even more watts than advertised. Not often you actually get what the product is rated. These do. So good I bought 2 more. It's easy to expand battery capacity and with a little ingenuity and research it can be expanded even more. Would recommend for others just getting into solar.

I use this at our island cabin. I wish I would have not gotten the solar panels. It charges very quickly off a generator. It will run a toaster, blender and microwave but it burns the energy fast. I have hooked them to gas generator and my eco last for over a week or better.

Powerful enough to run my refrigerator for three days without recharging. Very easy to operate and run other items,ntoo.

I purchased this and had it plugged into a normal wall outlet. First attempt at using it, (after 30 days) would not charge anything and would not stay on when unplugged. TRASH. So, I downloaded the app, spent 2 days with EcoFLow Tech support trying to get the firmware to "remote update," which required me to get the delta 2 on a network with my phone to push the update manually, and after this, it still did not work. Soo, reached out to Ecoflow support a 3rd time, was told after 30 days, they can't give a full refund because of 'depreciation' and I would be responsible for shipping costs. They offered a repair, which wasn't guaranteed, and if it failed, they would replace it with a refurbished one. And they offered just swapping for a refurbished one also. I have phots of the serial no.. screen shot from their customer service live chat as proof of this, and pending an email for prepaid return shipping at this time. We'll see if they can repair it and send it back, or compensate more appropriately. My thought is, if they can see the device online and push firmware updates to it, they should be able to see its up-time also, and can verify that the delta 2 was not even used, and that it didn't 'depreciate' by sitting on tile charging before discovering it was just draining power for no reason. I'll update this post if anything changes, purchased Nov 2024, reviewed May 2025.

So far so good! Super quiet for sure, instructions are very basic, multiple ways to charge as well as multiple ports. No more running to get gasoline and fuel treatment.
