Good design and well made but absurdly priced
It fits my EcoFlow Delta 2 just fine, and the openings are all designed to allow for connection and airflow while it’s in the bag which is good for sure, but the price on this thing is just absurd. Honestly, I debated giving it only 3-stars because of how off-putting the price is as it was listed for $74.99 when I ordered it. The only reason I didn’t is because I see, as of when I writing this, they appear to have at least slightly considered the absurdity of that price and it’s now being listed at $64.99. I still think that’s incredibly high for a bag, regardless of whether or not it is waterproof and custom fit for this solar generator, so that’s why it’s only a 4-star item for me. But yeah, aside from the price issue I do think it’s a good bag, well made, and with all those careful considerations put into the openings to allow for use in less-than-dry conditions. I’d still be hesitant to use it overly damp situations unless I absolutely had to, but this bag will at least allow me to use it without much concern in early morning, damp-grass scenarios when I might want to start some outdoor projects early and need a power source away from actual shore-power.

Nice cover if you need to use your Delta-2 in wet weathe
Until I saw this weatherproof case for my EcoFlow Delta 2, I would never have considered using my power station in bad weather (except within a tent or vehicle.) Now, (while I think I would still prefer to keep my power station “inside”), I believe I could use my Delta 2 in wet weather without worry. This thing is basically a waterproof tent for the power station.

The Amazon write-up basically says it was custom made for the Delta-2, and that’s apparently true in almost every fitting of this cover. It has flaps that let you allow air flow to the side air vents (in case you’re fast charging or drawing enough power to run the fan) while still keeping them under cover. Both the front and back panel have zipper covers to allow you to access the outlets and controls as needed. The front cover is see-through, so you can watch the panel display to check on power station status.

The cover comes in a zipper storage bag, so you have a place to keep this when you don’t need it (like, when using it in the house), but I can see folks using this all the time if you tend to keep you power station in the back of your work truck, for instance. Regarding storage, there are also covered pockets on each side of the cover, so you have a place to store your charging or power cords when not in use.

One thing to note is that there’s absolutely NO instructions, or even manufacturer’s label, on this cover. You’ll want to test-fit the cover as soon as you get it just to make sure you have the right cover for your power station. In my case, it seems to fit as expected.

While the usage is pretty much self-explanatory, there are a couple of straps with quick-snap clips (see my photos), and I can’t figure out what they’re for. Even with the straps fully extended, they don’t reach across the top of the power station, which is where I’d expect them to go, to help hold the cover in place. Note that there doesn’t really seem to be a need for them, as with the cover flipped over the top and velcro’d in place, it’s not going to go anywhere. I suspect that maybe for covers on different models, these might be useful, but they seem to serve no purpose here.

Actual rating: 4.5 (lacking any instructions, paperwork, or label), 5.0 for functionality.
