Light and energy in the darkness around
on January 28, 2023

Frequency of use:Daily
Gender:Male
A year ago, I would never have thought that I might need an alternative power source. But I live in Ukraine and a war has started in my country. Therefore, the availability of electricity during frequent blackouts has become a vital necessity. The ability to continue working when part of the city is in total darkness is what I owe to the Ecoflow Delta 2. I chose this particular model in the first place because of its reliability, stability and durability. This device has served my family faithfully for almost 3 months. And I am absolutely satisfied with it.

Simple and Powerful Station, Inconsistent App
on January 29, 2023
Posted by: Elliot

I purchased this as a combo with the 220W solar panel a few months ago. It charges incredibly quickly via wall outlet and is easy to hook up a solar panel to. The screen is easy to read and the app is very convenient to monitor power input and delivery as well as control different features, such as charging/discharging limits or switching the different power ports on/off. I also purchased a weather-resistant cover which is nicely made. The top compartment is very convenient for storing cables.
Here are some of the parts I dislike. The Auto Timeout feature is nice but can still trigger if you are powering something with low current, such as a string of LED lights. The app frequently takes a swipe down refresh to reconnect. Annoyingly, reconnecting to the station after leaving it overnight will sometimes be impossible until you physically power cycle the station. Even more annoying is if there are cables plugged in it can be difficult to power off the station until you unplug all cables. I have also noticed when camping with it, in the morning it did not start charging with direct light on the panel until I disconnected one of the solar panel cables and reconnected. The solar panel I purchased with it shows signs of the material around the grommets failing after a couple uses. It seems like a lot of weight to rely on grommets to hold up, especially when mounted in a semi flexible material.
Overall the station itself is well built and has plenty of power for long term use. It has some annoying quirks, especially when using the app, but the unit itself is very good at what it does.

Great power in a small package!

I was lucky enough to be able to pickup my new Ecoflow Delta 2 on Black Friday, the deal was so good and with these specs it knocks any thing comparable to the delta 2 out of the park. I regularly go off roading and camping, before this I have a GoalZero Yeti 500x (which is only $150 less for a much less capable unit) after getting my dometic fridge and now a diesel heater this winter I found myself needing a bigger unit. The specs speak for themselves and in a package the size of a small desktop computer I couldn’t be happier with the Delta 2. I also work in construction and we don’t always have readily available electricity to warm up our food… just for fun one day I brought it in and it powered our microwave with no issues!! I was pumped! I highly recommend the Delta 2!

Almost The Perfect Overlanding/Small Camping Unit!
on March 15, 2025

For the price point, this is a very good mid-sized power station. Love the fast charging and battery expandability. It's my daily workhorse for around the house, but I wouldn't take it overlanding/small teardrop RV camping. I just hope EcoFlow one day develops an "upper" mid-sized unit, geared towards the increasing number of small RV owners. The Delta Pro and Delta Pro 3 are great for 5th wheels, but they are too much to haul around for 13'-18' sized RV's (equipped with AC's and electric heaters). I can rough it, but my wife needs her creature comforts!
For my needs, I'm forced to haul around a Delta Pro with an extra smart battery, which is a bit too much for overlanding/small camping (teardrop RV). The ideal Delta 3 "Ultra" would include the following:
-2kWh of battery capacity
-A TT30 port for direct RV connection
-An ultra-efficient AC inverter (the Delta 3 Plus goes dead in 24 hours when the AC circuit is turned on with nothing plugged into it - very poor AC parasitic drain)
-Either a third 500 watt solar input port, or a single solar input which can handle at least 150 Volts (1200 watts maximum solar charging at the minimum)
-7kW+ total battery expandability with at least two battery ports (for Alternator Charger use)
-A TT30 port for direct RV connection
-An ultra-efficient AC inverter (the Delta 3 Plus goes dead in 24 hours when the AC circuit is turned on with nothing plugged into it - very poor AC parasitic drain)
-Either a third 500 watt solar input port, or a single solar input which can handle at least 150 Volts (1200 watts maximum solar charging at the minimum)
-7kW+ total battery expandability with at least two battery ports (for Alternator Charger use)
Again, I really like the Delta 3 Plus, and it has its place in my EcoFlow power station arsenal. It's just not ideal for my primary needs. If a Delta 3 "Ultra" were ever released, just tell me where to send you my money!
Thanks EcoFlow for making great products!

Just in time for Hurricane Ian
on September 28, 2022
Posted by: BobsDelta2

Received my Delta 2 a couple days ago as Hurricane Ian took aim at Florida. The manual was clear and easy to follow. When I turned it on, it showed 27% charged. From the wall outlet, it charged fully in less than 40 minutes. This morning, no power thanks to Ian, so I put Delta 2 to the test. First a couple of LED lights and a fan, then the most important thing to start my day .... my Keurig coffee machine. It brewed two large cups of coffee effortlessly, peaking at about 1376 watts. Yes the fan was audible for a few minutes but not nearly as intolerable as a generator. Then for the heck of it, I plugged in a 10,000 BTU 16 EER air conditioner and Delta 2 did not skip a beat to get it running. I ran the AC for about 10 minutes just to cool a bit and lower the humidity. I also ran the refrigerator a couple of times until the compressor went off. In the mean time I connected the solar panel. There wasn't much sunshine but I still got about 120-130 watts. at the end of the day, my Delta 2 sat at 89% SOC, enough to get me through the night. This little beast performed flawlessly and was so simple and intuitive to use. I will definitely be getting an additional battery and solar panel. This will be a great creature comfort to go camping or picnicking.
I would recommend this to a friend!

Just received my EcoFlow DELTA 2. Only used a few times so far. I like everything, everything is as indicated in the description. Can definitely recommend! Very convenient device! I am glad that it really meets all the declared characteristics. And also - it is not heard at all! Works very, very quietly.

Awesome portable power station and app
on February 4, 2023

Recently purchased the Delta 2 and extra battery. Was interested in the newer battery type: LFP
I have a had a pretty decent experience with using this, especially after coming from GoalZero Yeti 1000, where it was slow in recharging, pretty heavy, and no app.

One of the selling points of the Ecoflow products was the ability to fast charge via AC or solar. Via AC plug it took roughly 4-5hours to charge up both the Delta 2 and extra battery from 0% to 100% at 4-500W. Recharging from solar was also relatively easy and went from 85% to 100% in a couple of hours with a 120W panel on a sunny day. Overall, very impressed with the product as a whole. The app is also useful in looking at the battery stats and turning on/off certain ports (AC/USB/12V DC/etc) and looking at remaining time or recharge times.
I did experience an issue where I left it charged to 100% and over the course of a week, it kept dropping 1-2%, but reading through the owners FB page helped in guiding me to perform a BMS reset (discharge to 0% and slow charge back up). After doing this, I no longer see any drops.

My only wish is that it would have been great to have the extra battery function on its own. Other than that, I have an upcoming camping trip, so we’ll see how it fares.
