Style: DELTA 3 Ultra+400W Solar Panel
Quality unit if you need one. Simple to setup but there are some caveats. First off the 400w solar panel is a beast. You better have ate your wheaties if you wanna lug this thing around and set it up. The generator itself isn't lightweight either. I would recommend finding a central location on ground floor to leave this. Stairs would be rough. Also if you charge solely from the grid (drawing 1800w) for any length of time be sure youre wiring in your house is up to the task. I initially plugged the unit in on an outside outlet that is a 15 amp circuit with 14 gauge wire. The wiring was "warm" after a few minutes. If you have older wiring in your house or lighter gauge wire on the circuit you plan to charge the unit on i would urge caution because this thing draws a lot of power. That said it operates flawlessly and does exactly what it says it will do. I can run my camper and in event of power outtage I can run my fridge or my wife's computer while she works from home. Would recommend!

Style: DELTA 3 Ultra+400W Solar Panel
I recently added the EcoFlow DELTA 3 Ultra with the 400W Solar Panel to my setup, and I’m beyond impressed. This powerhouse keeps my essentials running with ease — from the fridge and lights to my laptop and tools — and it charges back up incredibly fast with solar. The 400W solar panel unfolds easily and starts pulling in energy right away, even on cloudy days. Paired with the DELTA 3 Ultra, it gives me true off-grid freedom. I can keep my home powered during outages or take it camping and still enjoy all the comforts. What really stands out is how quiet and efficient it is. No fumes, no noise — just clean, reliable energy. The display is clear, setup was simple, and the app makes it easy to track everything in real time. If you’re looking for a serious all-in-one power solution for emergencies, travel, or daily use, the DELTA 3 Ultra + 400W Solar Panel combo is hard to beat. It’s strong, smart, and built for peace of mind. The DELTA 3 Ultra delivers 3,600 W continuous output and up to 7,200 W surge (according to spec) with X-Boost support up to ~4,600 W for heavy loads, all packed in.74.3 lb units that this 56 year old woman can easily move around the house

Highly recommended—a very powerful unit that charges extremely fast; it weighs 79 lbs (including the box), and you can connect whatever you want to it.

This was a great purchase...it was meant to be for camping but works in many applications! I was surprised how long it holds a charge. I'll be buying additional batteries for future use. It seems to be of good quality, time will tell about longevity but so far so good!

Ordered the ecoflow power station for my he shed. (3071wh DELTA 3 Ultra Portable Power Station with 400W Solar Panel) It is a good out of the box solution. I hung the solar panel on the outside wall of the shed and ran a 25 foot power cable (separately purchased) to the portable unit inside the shed. I am seeing 250 watts of power, it is important to note that it could be better, I flat mounted the panel on the wall, I am not hanging it at an angle. The unit works out of the box, I haven't configured a top and bottom charge limits yet, I will though, probably 90% and 10% or whatever the research tells me to set it at. The handle makes it easy to move, that's important as it is a heavy beast. I didn't realize until I received it but this is the unit that can't be expanded. If I did better research I would have got a unit that I could daisy chain expansion batteries too. Still a good value and I like it. Now I have power in my back pasture at my shed. I have ran an air compressor, nail gun, skill saw and my fridge off of it and then watch the power charge back up.

This was a large purchase to allow us to keep our freezer and refrig on when our power is out. Haven’t had the chance to use yet.
