Upgrading from a previous ECOFLOW unit, looking forward to the extra storage and output of this unit
This is our second ECOFLOW product we’ve owned. Our first was a Delta 2. It served us well, but ultimately it was too small. That’s where this one comes into play.We chose this unit because of it’s storage capacity, power output, ease of attachment with accessories and ECOFLOW’s reputation. We could have gone a different route, such as a different brand or simply building my own solution, but ultimately this was the better solution for us.ECOFLOW is the solution to go with if you need a solution that works out of the box.We’ll be using this unit with our 1400 W of solar panels we’ve assembled plus the Alternator Charger we bought to work with the previous unit.ECOFLOW has a good reputation regarding quality. Our previous unit never had any issues and I don’t anticipate this one having any issues.One word of note – It’s heavy. It rolls on built-in wheels and has a built-in handle to help get it around.

A Game-Changer Add-On for My Delta Pro, More Power, More Savings”
I absolutely love these EcoFlow units. This Delta Pro Extra Battery is no exception. I own several EcoFlow products, and they’ve consistently been at the top of my list compared to other brands I’ve tried. This extra battery connects to the Delta Pro easily. It is heavy, so you may want someone to help you move it, but the wheels make rolling it into place simple. It comes with a very solid, thick connection cable that attaches securely to the Delta Pro.The extra battery has given me a huge boost in runtime. We use our Delta Pro as part of a backup system with a transfer switch, and adding this battery has made everything work even better—especially during outages and peak-hour usage. We already have solar on the house, so pairing that with EcoFlow has actually helped us reverse our electric bill. Pretty amazing.One of my favorite things about EcoFlow is their app. It’s smart, reliable, and shows exactly how long you have left on your battery, how long it will take to charge, and the wattage each device is pulling. I also love that you can use third-party smart plugs in the EcoFlow app; I use Tapo plugs and they work great. You can set timers and manage everything right from your phone.Charging flexibility is another big win. Whether I plug it into a standard outlet or charge it through solar, it’s quick and efficient. I personally charge mine at a lower wattage, but it’s capable of charging much faster if needed.EcoFlow always has great deals, excellent customer support, and a dependable honor system. This extra battery was a must-have add-on for my home setup, and I’m thrilled with how much more power and freedom it gives me. A fantastic upgrade.

Stellar performance, one of the best apps I’ve ever used
I would like to start out with the app which crosses over into the feature set. I’m an Android user and I find that most companies will focus more efforts on their iOS app; Android being “the red headed step child”. That is NOT the case with Ecoflow. I can’t speak to the iOS app, but their Android app is absolutely top notch. I would go so far as to say it’s in the top 5 apps, as far as user experience goes, that I’ve ever used.Getting the device connected to WiFi, upgrading the firmware, and getting it set up is extremely intuitive, never had any issues or errors which are typical with other devices (not just power generators, but all devices that connect to WiFi). The intelligence to include a lower charge shut off and an upper charge shutoff tells me that they really considered the lifecycle of your investment. Additionally, you can limit the amount of wattage the devices charge at for their various charging methods, that’s just going above and beyond in my opinion. You don’t have to worry about tripping any breakers or anything like that.As far as hardware goes, they’re pretty solid devices. From the rugged exterior and cables down to the quality of the LCD screen it’s all very well built. I LOVE that they had the forethought to include the collabsable handle and wheels because these suckers are HEAVY. On that note, I wish they put hand holds in the box that they come in. Carrying something that heavy and awkwardly sized to get it in the house and unboxed is a bit of a pain. I aggravated a knee injury in the process; although I’m partly to blame for that one. Simple perforations in the sides of the box for the hand holds like many other manufacturers of large gear would go a long way.I’ll close with their customer service. I happened to catch this on a bundle + a deal that included a grounding module. Apparently, during checkout with Amazon, there was a checkbox that I didn’t check to opt in to this deal. When I contacted customer service, they pointed this out, but still asked me for my shipping address and sent me the grounding unit at no cost to me! Additionally, I’ve been contacted by them since receiving the bundle to make sure that I was all set and addressed the single question I had. I really ask that anyone reading this part goes back to the beginning of this paragraph and reads it again. When is the last time you got what you would consider even “adequate” customer service? When was the last time you got “good” or even “excellent” customer service? This is one of the best customer service experiences I’ve ever had if not THE best. I want to emphasize that they weren’t annoying about it either. I simply had a voicemail one day from them stating that they were just checking in to see if everything was working OK and if I had any questions to give them a call back. A single voicemail. No emails, no multiple phone calls, just a voicemail. Point is, I wasn’t being harassed. They just wanted to make sure that I was set with my investment.Delta Pro 9/10EcoFlow App 10/10EcoFlow Company 11/10I’m docking the Delta Pro a point for 2 reasons (and this really applies to the extended batteries as well). One being they could’ve put a little more thought into the cumbersome nature of moving the box around, simple perforated hand holds in the outer carboard box would’ve rectified this. Also to that point, it would be nice to have a less conspicuous box. Anyone within viewing range could’ve easily looked up what EcoFlow offers and known these boxes were worth stealing. The second reason I dock a point is that I’d like included is some dust & water resistant covers for USB and AC outlets. To charge the device, there’s a door that flips up (not spring loaded) so that’s at least a little protected. These are going to be in my basement and there’s going to be dust. I know they offer a pretty expensive cover for this reason but some removable rubber plugs I think is minimum as the cost of them justifies a little more forethought for protection of the power outputs.I have already recommended them to anyone I’ve talked with looking for a power station, generator, or reliable battery backup for important electronics. Just this past week a tornado went through our neighborhood and someone was looking for backup suggestions because their sump pump went out and their basement flooded. I recommended the Delta 2 (the Delta Pro is a bit overkill for a sump pump).

Fonctionne très bien jusqu’à maintenant.Utile à mon camp pour faire fonctionner mon réfrigérateur et mes équipements 12V et 110v.Avec mes panneaux solaires, la recharge est essez rapide, soit 80% en 7-8 heures de plein soleil en gardant la bonne orientation des panneaux.Seul, le poids du Delta Pro est agacant à 99 lbs

Excellent quality generator (it’s a large rechargeable battery), and the best flexible solar panels I’ve seen yet. I required a couple of sturdy sticks to hold up the outside panels properly. It’s unfortunate the generator lacks an additional input port for another 400w panel. You can hook additional but they must be hooked into panels that are already plugged into generator. The 4x 100w (400w) panels are connected in series, meaning if one panel (100w) is shaded, it significantly reduces the output for another connected 100w panels. This is ok, just have to ensure you move them around. It’s a good purchase.

Hi im lin in Vancouver bc canada, i bought 7.2kwh ecoflow delta-pro early this year and ecoflow 800w alternator charger late last year. From April 2025, i ve used them in my camper van and they have brought great convenience to my camper van life.Late august, the solar panels charging was out of order for my delta-pro( maybe due to my removal of damaged in-line 15A fuse for the solar panels), after contacting the service team of eco-flow, they let me replace a brand new main battery of the eco-flow for free. From yesterday, i added a new 15A in-line fuse to my solar panels and the delta-pro has worked normally from yesterday. I appreciate a lot to the service team of eco-flow for their kind snd professional helps for my solar charging fault.Btw, if eco-flow can provide ev-charging station adapter by connecting from the back of the delta-pro battery back , that is better. Currently the adapter for ev-charger connects through front side port which is hard for charging for its location is in facing forward and blocked by the van side. I think most camper van users have the same setup as me.Regards Lin
