I have three solar power stations; a River Pro, a Delta 1300, and a Delta Max 2000, and six EF160 Watt solar panels. I use them to supply loads in different parts of the house in the event of a power outage. Charging on the AC line is very fast, as described in EcoFlow’s manuals. On the Delta Max the rate of charge is selectable between FAST and SLOW with a switch on the power station, and the slow rate is adjustable from the mobile phone App. On the RiverPro you can set slow charging with the App. Using SLOW charging will be easier on the batteries, but FAST charging is there when you need it.* Charging will proceed at pace until it ramps down as the batteries approach a full charge, whether using AC or solar input. Don’t be alarmed as you see the input watts throttling back. Think of a jet plane coming in for a landing. You wouldn’t want to land at 600 MPH. Neither do the batteries. In use, there are a few things you can do to maximize runtime. Keep the power station cool. As the internal temperature rises, the fans will come on, running faster as the temp increases. The fans use power that would ordinarily be available for your load, so minimizing the need for them is to your advantage. And, obviously, keep the power station in a dry location. Don’t use the inverter if you don’t need to. If you can power your phone, laptop, or tablet with their USB cables, do so. The same is true if you have a set of low-voltage LED lights on a USB cable. You won’t need to switch on the AC outlets which use power to run the inverter. And it’s probably a minor point, but I’ll mention it anyway. Using the Wi-Fi connection is handy but it also draws a little bit of power which would otherwise be available for your load.* And finally, solar panels may not deliver the amount of power you expect, even if they are positioned perpendicular to the sun and free of shade. The efficiency of solar panels is related to their temperature. As the temperature goes up, the panel’s output power goes down. What you get from a solar panel in winter should be de-rated in summer. * Note: Slow charging and Wi-Fi are not available on my Delta 1300.

I do a lot of motorhome travelling and often stay off grid, so was looking into solutions to enable me to stay off grid for longer periods. I researched the market before purchase and the Echoflow Delta Max was the product that stood out. I'm really pleased with its versatility, performance and overall quality of the product. It does exactly what it says on the tin and gives me the flexibility I was looking for.

Love my Delta Max 2000! Powers my Iceco VL60S fridge for a week with no problems, allows me to make that vital first cup of coffee with my Keurig mini and charge my laptop. For weekend camping I rarely have to bust out the solar panel. Haven't needed it for backup power at home yet but it's nice to know I have it if needed. Just purchased two 160 watt solar panels during the members only sale event and can't wait to see how fast they will charge this unit. I also have a River Max that I use for charging phones and tablets while camping. EcoFlow is my go-to for solar generators. Great products at great prices. My only gripe is that some of the firmware updates don't "stick" unless you use the unit to power or charge something immediately after the update installs. Took a while to figure that out. I installed one update, only to have to install it again when I powered on the Delta Max about 5 or 6 times, I finally used it to charge my phone immediately after the firmware install and that is when the update finally stayed installed. It was a bit frustrating but glad it wasn't a problem with the unit.

I have had my Delta Max 2000 for several months. It is amazing!! It was able to power a TV, router, computer, and coffeemaker without a problem. I was surprised at how little power was drained. It was easy to charge and use. I am not mechanically minded but the instructions were clear and easy to follow. Having the Delta Max gives me peace of mind regarding future power outages.

I purchased the Delta Max, extra battery and a couple of solar panels for blackout situations. This is an increasing occurrence where I live and I want to be prepared. Having my generator and panels gives me much more peace of mind should the situation get dark, literally and figuratively.

First off, I must say that once we were able to figure things out, we love this Delta Max combination. It is just as advertised. The one negative thing we found were the instruction manuals. In our opinion they were not detailed enough. They needed more of what to expect after doing this or doing that as you follow the manual, we would follow an instruction and think did that work and now what. Sometimes they is a delay between actions and you think did we do this properly. Not the detail we would hope for.

Going into another hurricane season here in south Louisiana and I am ready for just about anything power wise. Delta Max 2000 with smart generator with a home made adapter to connect to my home transfer switch. The big game changer is the ability to power the house all night without having to run the generator. Last year after hurricane Ida, the problem was to run the generator at night you were advertising the fact that you had one and always had to worry it might get stolen. With the Delta max, it can be brought inside at night and kept safe while at the same time powering our lights, computers and refrigerator. With the smart generator, the engine only needs to run when the Delta max needs power, saving noise and more importantly gasoline. I also have two smaller Ecoflow units (river max and deta mini) that will keep power on to the computers and refrigerator while switching out the delta for another generator, or while moving it inside at night. I might add some solar in the future to save a little more on generator run time and gasoline. But, for this season I am pretty happy with what I have. In testing, on a cool enough day not to need the air-conditioning, the delta managed the whole house.. all the lights, refrigerator, tv, computers, even the microwave with ease. My wife didn't even realize the house was being powered by a battery. Great products from Ecoflow.

Bought the Delta Max just recently to provide power to our freezers if a storm knocks out the power. This unit exceeded my expectations as it as very good build quality, is not heavy and can tucked away in the closet without taking up much room. It recharges quickly and is easy to use. I am planning on buying the Pro model very soon to use for extended outages.

5.0 out of 5 stars This thing is a fantastic. I picked it up x 2 and also 2 x 400W solar panels. I documented the unboxing for this review, really well boxed and simple instructions, nothing excessive. Sturdy for keeping. The panel carry bags are sturdy, they need to be for the not light panels. I would not go dragging them on the ground [my OCD], and i used a thin drop cloth for most of my setting up and placing of the panels. Using rubber gloves like ATLAS is a must for ease of set-up. Probably a 2 person job, otherwise you need to think ahead, so the panels don't tip or overflex. At the price point i would have expected to have had a bag for the Delta Max unit included. My needs are to power my at home computer kit, for 2 work at home adults and a child with 2 monitors!! Plus a tech heavy house. We are in NorCal, but due to the way our roof is chopped up, we can only get a small 4.2kW solar system plus 2 Tesla PowerWalls, this hits to areas; supplements that system with low stress, and gives us a portable unit for outside entertainment needs [lights, sound, temporary cooking / ice]. I do however have a balcony [suntrap] with a large surface to accommodate the 400W panels, (will be placed on a trellis roof we are building on-top of the balcony). It gets peak sun all year around in the 10:00 to 14:00 sun-power band. These things kick it out, i monitored it from the morning 6am [slightly grey, sun not above the horizon and local shading], at about 22W input, which steadily increased to now [11:37 pacific] to 500W, the battery is fully charged. Open book, i had charged it a little. When it arrived its at 30%. So i hooked up the solar system during the unpack, but it was cloudy so i ended up just plugging it in to the AC for a 1.5 hour to full charge. I hooked it up to laptop, large draw monitor and a bunch of tech equipment. So, now 11:40 it is simply pulling 140W from the solar, for my 120W consumption. But for the next 3 hours i can get 800W draw, before i will fade and then drop over to battery draw. That said the panels became shaded after 2pm.....i used the power for the rest of the day [laptop, large monitor, charged a phone and a JBP speaker], drawing about 120W, total. The solar panels where regulated producing about 140W. Overnight, my hub and a bunch of internet gear had been drawing 20-30W, and left me with 11 hours as i turn my computer and monitor etc on [drawing 80W to 110W]. It is 08:00 and i am getting 22W from the solar, and will be about another 2 hours before the solar starts to kick in, at 09:30 i am getting 60W input and climbing, and i will continue to write about how long it is before i hit 100%....10:58 at 377W solar input, and a fill time of 3hr53 minutes or less..... 401W at 11:05 and charge time of 3hr25min or less. So it got up to 81% before the shadow came over the panels. Not ideal, but it is 20:00 now, and it should last overnight. 06:55, 60% charge...light use this morning [just the laptop, no big monitor], and at about 08:26 the panels are picking up 60W and meeting my demands. I learnt yesterday that laying them flat is the best option with the real estate i have. All in all, really like it. What a great bit of kit.

I purchased the Max 2000 and love it. I like that you can use the App from anywhere and make adjustments as needed. Also, the UPS feature will come in handy when a storm approaches. Very glad I bought and it gives you peace of mind during power outages.
