## Description

desertcart.com : EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV : Patio, Lawn & Garden

Review: Absolute game-changer for vendor markets! - We’ve been using the EF ECOFLOW Portable Power Station 3600Wh DELTA Pro to run our heat press at vendor markets, and this thing is an absolute beast. It handles the load with zero issues. No voltage drops, no struggling, just smooth and consistent power the entire time. The 3600W output is more than enough for our setup, and having five 120V AC outlets makes it super easy to plug in everything we need without juggling extension cords. It fires up fast, runs quiet, and gives us total peace of mind when we’re on-site and making products live. Battery life is impressive. We can run multiple presses without constantly stressing about recharge time, and the build quality feels solid and professional. It’s clearly designed for real work, not just camping or emergency backup. If you do markets, pop-ups, mobile businesses, or anything that needs serious, reliable power without a generator, this is 100% worth it. One of the best investments we’ve made for our business. 💪🔋
Review: Best Yet! - Excellent portable power solution for camping, emergencies, or on-site work. Battery management is solid, with decent recharging options and a responsive display. It’s a bit heavy, but that’s expected for the capacity. Overall, a dependable, versatile unit.

## 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.

## 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

### ⭐⭐⭐⭐⭐ Upgrading from a previous ECOFLOW unit, looking forward to the extra storage and output of this unit
*by G***E on November 27, 2025*

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.
