EF ECOFLOW8kWh Portable Power Station: DELTA Pro 3 with Extra Battery, 120/240V 4000W AC Output, Solar Generator for Home Use, Camping, Emergencies, Power Outages, RVs, and Outdoor Generators

It Like that it integrates very easily and includes the attachment cable to the Main DP3 UnitJust works as advertised !Price is expensive, but so is all GOOD Technology

Got the product and plugged it into my Delta Pro 3 and nada. I tried for a week to charge the extra battery and no luck. Called Exoflow and found out I had to have the app to update the firmware. Once I did that it took like 3 hours to fully charge. Only weird thing it will only let me charge to 99%. Other than that waiting to finish my container to plug it in and make sure it all works with the mini split

This was very instrumental when Hurricane Helene came through SC with all its destruction and my power was out for 14 hours and all I had to do was plug my refrigerator into the Ecoflow power station. It was plugged in for 12 hours of the 14hours and I still had 79 per cent of my power. No gas to purchase and it stayed inside the whole lime with no fumes and no noise. How wonderful is that!!!!!

We ordered the Delta Pro 3 with extra battery and the extra battery was never shipped.When I turned on the Delta Pro 3 it showed an error message Overvoltage protection (312) Disconnect the appliance from USB-A Port 1 and nothing has been plugged into the USB-A Port 1Update: Eric in customer service was very helpful. We received the battery the following day. Eric was prompt on sending us out a replacement for the main unit. We have charged it and it seems to be working. Can’t wait to try it out on the road.

Add ing the Extra battery is simplicity, lift the battery in place and make the connection with the supplied cable, done, your extra battery is installed. With the addition of the Delta Pro 3 (DP3) Extra Battery you find your units Watt Hours doubled from 4096 to 8.2 KWH. In addition you discover a fully integrated battery in that the DP3 manages and balances the two on board batteries during both the charge and discharge phase, switching between the batteries to maintain a balanced charge state. It doesn’t get much easier than this!

Update: The seller absolutely gets 5 STARS!!! The replacement was sent fairly quickly and this new one will run without shutting off for over 24 hours and is still running. It accepted the solar panels without any problems. Will certainly purchase from them again!!!Previous review: There have been several issues with the solar port and shutting down at this point. Seller has reached out to refund me due to some issues and ECOFLOW is looking into the matter. I’ve investigated time and money into this project and would prefer another unit or this one fixed outside of a refund. If it’s resolved I’ll update the review.

What a great package with an added battery. We have an off grid cabin, so it will definitely be useful

Matches the pro 300 and sits atop well. Looking forward, not looking forward, to its use just in case.
