This is a great product. I have tested it well and it is the solar array that I own.

It was able to more than double charging capacity. Improves overall performance.

Fast charge, have nit needed to use. All cords came with it, seems to be As Expected

Excellent product, shipping was efficient. A question was answered the same day

No generator delivered only the panels came.

I love my new Delta 2. The Delta 2 is a second generation update of the original Ecoflow Delta 1300. It's many improvements include longer lasting much safer LFP Lithium Iron Phosphate batteries, an expansion battery port, more solar input (500W) and an even faster charging time than before. They have made many noticeable improvements under the hood as well, integrating circuit boards to cut costs and keep the same weight (LFP batteries are heavier!), improving efficiency - yet the Delta 2 is less expensive than the original Delta 1300! 
I have two Delta 1300's from the original kickstarter campaign - they really revolutionized the solar generator business and set a standard all the legacy companies have since been trying to catch up with. Before Ecoflow solar generators looked not unlike modified gasoline generators - that is industrial and clunky. But the Delta 2 like the rest of the line, look much more friendly, they blend ergonomically into any home environment rather than looking out of place like they really belong in the garage. 
But the killer feature has been the fast charging. The group of 20 somethings that founded Ecoflow had worked at drone maker DJI together, and observed the biggest pain factor was how long it took to recharge batteries. And so they figured out fast flash recharging in under 2 hours, 1.6 hours on the original Delta. The new Delta 2 can flash recharge now even faster than the original, in an hour and 20 minutes, all Ecoflow solar generator charge in under 2 hours, even in an hour for some, yet there are still competitors out there that take over 10 hours plugged into the wall. 
I did observe that when the Delta 2 is cool it charges a lot faster. Checking the internal temperature with the phone app to be 96°f, it charged at near 1200 watts on the meter, slowing down a bit at 80%, eventually fully charging in exactly an hour and 20 minutes as advertised. However if you discharge it at a very high output it heats up the batteries (I did a torture test and ran it at 1200 watts flat to 0%, with a hair drier in 30 minutes.) Then you have to let it cool down before it will recharge. After a cool down rest period, the still somewhat warm Delta 2 charged at a steady 600 watts the whole way. It took a little longer at 2 hours, but no complaint here. 
Great improvements, nice price point, expandable, lasts longer. If you are a fan of these kind of devices - you will love your new Delta 2 too I think!


I've been looking for awhile and found the right one for me. I ordered my EcoFlo Delta 2. I got it just in case the power went out. as soon as I got it, I plugged it in. it was fully charge on about an hour. I have Gas generator, but it's too noisy and has smelly fumes. I can't wait I to use it on camping trips. I use a CPAP and it will help out big time. I plan on getting more.

I own 6 of these panels now. The are the most cost effective way to use solar to charge the River series and the Delta 2 and Delta 2 Max. by combining two or more you can get close to max charging on the aforementioned products. they are small and lightweight and, for me at least, setup is quick and easy. I just lay them on any flat surface, including the ground, and they just work! I have gotten 95 watts out of mine, but I am at a low latitude. Your mileage will vary! If you shop the Ecoflow sales and/or use ecocredits these are the cheapest way to power your systems.They are also just as easy to take down. I highly recommend these panels.

I’m an owner of a few EcoFlow products - started with the River Pro and then I purchased the Delta Pro. Huge difference between the two in terms of capacity and capability. The new Delta 2 bridges that gap with a powerful product in a better price range. Fan noise is normal and the waterproof case is perfect!

Received my DELTA 2 and 220W bifacial solar panel a few days ago. Also purchased the extension cable for the solar panel (the cables included with the panel would have been everything I needed, but I wanted some additional length). The shipping process was fast (about a week) and I received good notifications on progress. Both the DELTA 2 and the solar panel appear to be good quality, and initial tests align with the expectations I had based on the product advertising. My original plan was to use the product mostly as an easier source of emergency in-home power than my gas-powered generator, but I'm now thinking of some other potential uses as well (UPS/backup for sump pump, power in the far corners of the property, an occasional picnic or camping trip, etc). I'm not sure I'll be using the phone app given the potential security risks of hooking an emergency power supply to an internet connected device. So far, I'm very happy with my decision to purchase the products.
