Today, we went out for a little trip in motorhome. The idea was simple: to let the cat experience his very first outing in our home on wheels, just to see how he reacts to van life. (Because before traveling long distances with him, it’s best to check if he enjoys the experience.)
But this outing also had a second objective: to test the new EcoFlow DELTA 3 Classic. A portable battery that could potentially replace the EcoFlow DELTA 2 that we are already using in the motorhome. The question is simple: is it capable of performing just as well, if not better, while being cheaper? That’s exactly what we’re going to find out in this article.

First impressions of the exterior
Before really talking about the test, I need to explain the conditions under which we tested the EcoFlow DELTA 3 Classic. Usually, when I receive a portable battery, I like to take my time: test it at home, use it for several days, and see how it performs in different situations. But this time, EcoFlow asked us for something a bit different: to conduct a test directly outdoors. Being a site that talks about van life, it was the perfect opportunity to bring out the motorhome, both to introduce the home on wheels to the cat and to test this DELTA 3 Classic in real conditions.
That said, to be sure of my approach, I still unpacked it at home before leaving. And I must say that, definitely, on the new generations, whether it’s the EcoFlow River range or the EcoFlow Delta 3, I find the design particularly successful. The battery immediately gives an impression of a well-finished product. It also seems noticeably lighter than the EcoFlow DELTA 2 that we currently have in the motorhome. I don’t know if it’s thanks to the new handles that make it easier to grip, but the feeling is clearly different. (And when you have to move this kind of battery regularly, this detail matters.)
On the front, there are two buttons above the main screen that serve to turn on the battery and activate the power outputs. I have a slight doubt about their durability with frequent use, although I could be wrong. On the front, there are also two USB-C ports: one 100 W port, perfect for easily charging a laptop like a MacBook Pro, and a second 30 W port, as well as a single USB-A port. Just below are the two 230 V outlets. At the back, the cigarette lighter socket has disappeared, but you still find the essentials: the socket for solar panels and the mains power socket to charge the battery.
When unfortunately an adapter is missing!
A small note at the time of unboxing: I was quite surprised to see that in the box, there is only a simple mains power cable (AC). Out of curiosity, I went to check directly on the EcoFlow website, and it is indeed normal for this model. However, it’s a bit lighter than what we used to find in some boxes before, where we also had the adapter to connect solar panels (MC4 to EcoFlow socket). This is not necessarily a problem, but just remember to order one if you plan to use solar panels; otherwise, you might be a bit surprised when it comes time to connect your setup.
Testing the DELTA 3 in real situations
Since I am in Portugal, I received the battery very late compared to its official release date. So, since EcoFlow asked me to conduct an outdoor test, the information I’m giving you should be taken with a grain of salt because I couldn’t push the tests to the end, which I will do by updating this article one day.
First test: charging the EcoFlow DELTA 3 Classic
Even before leaving with the motorhome, I wanted to make sure the battery was full. So as soon as I unpacked the EcoFlow DELTA 3 Classic, I simply plugged it into an electrical outlet at home to charge it. On paper, the battery is advertised to charge from 0 to 80% in about 45 minutes. However, when I plugged it in, I was quite surprised: the screen only showed 500 W input. Let’s just say that at that rate, we were far from the performance advertised by EcoFlow.
So, I installed the EcoFlow app. And I say this often, but after testing several brands of portable batteries, it is clearly one of the best-designed apps on the market. I wanted to check that the AC charging setting was set to maximum. It was indeed the case; the charging was configured at full power. I then wondered if I had received a throttled version of the battery. In reality, what was throttled… was my apartment. Once I turned off my computer, which was plugged into the same outlet as the battery, the input power immediately rose much higher, around 900 W.
Test number 2: a juice bar in the great outdoors
For the second test, we wanted to do something a bit more fun. As you can see in the video of the article, we went to settle in a particularly beautiful and very quiet place to… make some fruit juice. The idea was simple: use a blender, which can be quite energy-hungry, to see how the EcoFlow DELTA 3 Classic performs in real conditions. On paper, the battery is more than capable of powering this type of device at 230 V, so it was a logical test to conduct.
I won’t keep you in suspense for too long: of course, the battery handled the few seconds of blending needed to prepare our juice perfectly. The fruits were blended in about fifteen seconds without any issues. So this isn’t really a surprise, but it was mainly an opportunity to check that everything works normally in real-life situations. The next step will be a bit more interesting: to see how the battery performs when several devices are plugged in at the same time, as I usually do in other tests of portable batteries.
My opinion on the EcoFlow DELTA 3 Classic
At first glance, one might think: what is this somewhat budget battery? Why pay for a battery that offers fewer features, fewer ports, no cigarette lighter socket, and only two 230 V outlets? The question is legitimate. One can easily feel that things are being taken away compared to other models in the range. But in reality, this reasoning mainly holds if one has never used a portable battery on a daily basis. When living with this type of product in van life, one quickly realizes that many ports end up being hardly ever used.
In my case, after two years of using the EcoFlow DELTA 2 in the motorhome, I can say that I have hardly ever used the four 230 V outlets simultaneously, but at most two outlets. On the other hand, the USB-C ports have often been useful to me; the number of 2 seems perfect (the 2 at 100W could have even been better). As for the cigarette lighter socket, even though it could be useful for my 4G modem, I have never really used it with the battery. Ultimately, where an EcoFlow River can sometimes seem a bit limited as soon as you start working on the go, and where the DELTA 2 might seem a bit oversized for certain uses, this DELTA 3 Classic finds, in my opinion, a very interesting positioning. It offers the essentials, without superfluous features, and especially at a price that becomes much more coherent for this type of use.
Who is the EcoFlow DELTA 3 Classic for?
The EcoFlow DELTA 3 Classic is clearly a battery designed for nomadic use. Already because it remains relatively compact for a battery of about 1 kWh, but also because it does not offer the possibility to add additional batteries. So we are not looking at a solution intended to build a large scalable energy installation. The idea here is rather to have a portable energy source, easy to transport and simple to use in van life, camping, or outdoor activities.
I particularly think of people who work nomadically. For example, someone who already has a fixed battery in their motorhome, but who would like an independent battery to work outside, charge a laptop, or power a few devices without relying on the main installation of the vehicle. In this case, the DELTA 3 Classic⟧ becomes a particularly interesting solution: it remains powerful enough for most daily uses while being more accessible and simpler than the more complete models in the range.
