Great product!

There was an outage that affected my house and the entire block for a couple of days. Good thing I had recently bought my Ecoflow Delta Pro. What a lifesaver! We were able to keep lights on, some essential appliances, fans during the day, heater at night. Best purchase that I've made in a long time.
I would recommend this to a friend!

You get the basic chords no extensions and if you want to expand just be aware of how expensive the batteries are. Very good,BUT Just be aware of how heavy the system is and if you want solar panels you’ll have to buy extra wiring if you put more than one panel on it in parallel or daisy chain and have some kind of extension wires

I like this because its plug and play, its pricey but if you build your own and factor in time, money, safety and portability this is the best option for me.

No Adapter or Solar Panel Cord Included
on August 15, 2023

After much research online and watching lots of videos, I purchased the EcoFlow Delta Pro, Smart Dual Fuel Generator and 400w Solar Panels. I purchased the units not as a bundle but within weeks of each other as this is what my budget allowed. The units are excellent quality so far, however, the first time I tried to charge my Delta Pro with the generator, I discovered that the adapter plug that’s required to attach the genset to the unit via the Infinity port does NOT come with either the Delta Pro or the Smart Generator.
A few days later, I decided to charge my Delta Pro with the EcoFlow 400w solar panel array only to find out that the solar panels didn’t include the “solar panel to xt60i” cord! Insert head explosion. It’s ridiculous that EcoFlow does NOT communicate this well and even more insane that these inexpensive items are not included…even if they increased the price to compensate (hence the 3 stars for Ease of Use rating). It’s not about the money, it’s the inconvenience and stupidity of having to hound-dog the basic necessities to make this stuff work together as the system it’s portrayed to be. I would still purchase this brand but EcoFlow needs to stop splitting hairs and sell the adapter plug with the generator and the adapter cable with the solar panels. Had this been a clearly known factor up front, I would’ve simply added them to my orders to save the hassle and frustration.

Not a complete system
on December 19, 2025
Posted by: Dave 69
I purchased the EcoFlow pro series with 2 extra batteries. Also purchased the 4000 watt Smart generator. For my off grid cottage.
They are supposed to work together, especially during the short day winter weather. Big problem, I can't charge my whole system at the same time. There are only 2 ports to the Pro, so I have to sacrifice 1 battery when I charge them. PLEASE make an adapter so I can use my system in the way it was intended.

I'm a novice at the topic of Portable Power Storage. I was attracted to the EcoFlow Delta Pro for a couple of reasons.
First off, it's on wheels for easy maneuvering around the house. The unit is heavy (approx 100 pounds), so the extendable handle that makes it work like dragging a suitcase is a really nice feature.
Second, was the 3600 watt capacity. Our intention is to have the unit as a backup for emergency situations at home. The unit can easily maintain a refrigerator for 2.5 days or so.
Third, was the option to connect into Solar panel recharging.
Fourth, was the LiFePO4 Battery, which is the newer version of battery technology.

So far we have been very pleased with the unit. It is easy to move around and can run our Refrigerator and either a Toaster Oven or Microwave at the same time. Can also power my CPAP machine overnight for at lease 12-14 nights if not used for anything else. The Solar charging is dependable, but dependent on the type of panels you use and the sunlight available. Wall charging is quick and can be done from zero to 100% in less than 3 hours.

Great Backup and Works with RVs

I purchased this as a backup for my house in case of blackouts (looking at you Texas power grid) and also to use with my RV when boondocking. It's been fantastic, especially considering a lot of sites don't allow generators but they do allow portable power stations. I was able to power my TV and microwave off the Delta Pro for the 3 nights we camped and still had plenty of backup storage.
I would recommend this to a friend!

A great option for emergency backup power

This is an excellent option for emergency power or daily use. The unit is quiet and fast to charge with several charging options. Stand by mode works great for preserving the battery in case of power outage. The Lithium Iron Phosphate batteries ensure this will last for a long time. The portability of this unit means you can use this for home or when traveling. I got a few of the Ecoflow 180 watt solar panels to charge it with, which expands my options for any type of off grid or grid down situation. Overall a great product.
