The extra 3600Wh significantly extends the DELTA Pro runtime, making it ideal for power outages, camping, or RV use. Solid build quality and easy to connect. The only downside is that it’s heavy and expensive, but it’s worth it. Review: 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. ## Features - Expandable Capacity. With a extra battery, DELTA Pro can expand capacity from 3.6kWh to 7.2kWh for battery backup power supply. That’ll give you days of power for your essential appliances. - Charge Anytime, Anywhere. DELTA Pro’s extra battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro. Once connected, they’ll charge/discharge in unison, keeping the battery percent level across both units. - Ready for Any Emergency. When the going gets tough and you’re out of charge options, get a 1800W DC fast charge with EcoFlow Smart Generator (sold separately). Just plug the generator directly into your extra battery via the port on the back. This works even when disconnected from your DELTA Pro. - Stay Informed. The extra battery sports a bright LCD screen on the front of the unit giving you all the info you need. Output, input, remaining charge and time remaining. It’s all there. Need on the go info? The EcoFlow app can tell you all that & a whole lot more. - Smart Control. DELTA Pro’s extra battery can be monitored from the EcoFlow app, allowing you to monitor & control your batteries from afar. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09PBMZ5WT | | Antenna Location | outdoor | | Best Sellers Rank | #19,455 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #57 in Outdoor Generators | | Brand | EF ECOFLOW | | Built-In Media | Extra Battery, Charge Cable, Hand Cover, User Manual | | Customer Reviews | 4.6 out of 5 stars 287 Reviews | | Item Dimensions | 25 x 11.2 x 16.4 inches | | Item Type Name | power-generators | | Item Weight | 105 Pounds | | Manufacturer | ECOFLOW | | Model Name | EFD500-EB | | Model Number | EFD500 | | Recommended Uses For Product | outdoor | | Reusability | Rechargeable | | UPC | 842783147097 | | Unit Count | 1.0 Count | | Voltage | 120 Volts | | Warranty Description | 5 year warranty | ## Product Details - **Brand:** EF ECOFLOW - **Fuel Type:** Battery Powered - **Included Components:** Extra Battery, Charge Cable, Hand Cover, User Manual - **Item Weight:** 105 Pounds - **Output Wattage:** 3000 - **Power Source:** Battery Powered - **Recommended Uses For Product:** outdoor - **Special Feature:** Plug&Play home backup solution, clean and safe power, long-lasting LFP battery - **Voltage:** 120 Volts - **Wattage:** 3600 watts ## Images ![EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV - Image 1](https://m.media-amazon.com/images/I/51wwVOccO4L.jpg) ![EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV - Image 2](https://m.media-amazon.com/images/I/71sVY3hDRvL.jpg) ![EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV - Image 3](https://m.media-amazon.com/images/I/71B+BNQ+T-L.jpg) ![EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV - Image 4](https://m.media-amazon.com/images/I/71d7qnuoMCL.jpg) ![EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV - Image 5](https://m.media-amazon.com/images/I/71bW0oo3LPL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does it come with solar panels** A: Unfortunately, No the EcoFlow Generators do not come with Solar Panels. This product is rated by all the critics as being nothing but Top Shelf Cutting Edge Technology. With this being the case, EcoFlow probably made the decision not to include panels with the Generator, because everyone has different needs and a different budget. When I initially bought my EcoFlow Pro, I only purchased one panel. One is better than none. As, time went on, I bought 3 more panels, so charging time would be faster. EchoFlow sells different watt panels. 160W panels cannot be be mixed with 400W panels. When you buy panels, if you go with 160W, then the panels all connected must all be 160W. If 400W panels are in your budget, then you must use all 400W panels in your hook up. That’s how the EcoFlow Tech described it to me. **Q: What is the best set of solar panels to get for charging the delta pro 3.6KWH batteries?** A: The key to using solar panels with your ecoflow is you will need to link them in series. You are limited to 15 Amps. This also means you can't use commercial-grade panels, as most of those are much higher than 15 Amps. If you link them in parallel, you will overcharge the ecoflow pros and it will shut down. You are limited to a total of 1600W max, 11-150V DC, and 15 Amps. **Q: I am sure the answer is yes but i want to confirm. can i use an existing gas generator to charge the ecoflow?** A: Yes! I do it all the time. Just use heavy gauge (10 gauge) extension cords, to get the fastest recharge rate. **Q: Why is this called a "solar generator"? Can it generate energy from the sun? Is this false advertising?** A: with solar panels yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ “Reliable power anytime, anywhere with the EcoFlow DELTA Pro.” *by Y***Z on May 23, 2026* Great capacity and performance.
