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: So worth the purchase. - I bought this so I can run my home oxygen concentrator when the power goes out. Yes it is heavy to move around, but being able to have it inside is a plus. As soon as it arrived, I charged it up, did the firmware update and then I put my concentrator on it with just the generator, no additional battery. I had 10 hours 47 minutes available. That's awesome. Times that by 2 and that's the power I have before zero. A good set of solar panels will keep this running at peak. Cloudy days or night, I have a generator to recharge. Total peace of mind knowing between this and my tanks I will not run out of oxygen. I wish I could give this 5 more stars. I love this product.

## 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

### ⭐⭐⭐⭐⭐ • EcoFlow DELTA 3: A Dependable Portable Power Station
*by A***Z on January 3, 2026*

I’m very impressed with the EcoFlow DELTA 3 portable power station. It delivers fast charging, reliable performance, and plenty of power for a variety of needs — whether it’s for home backup, outdoor adventures, or emergency situations. With its high-capacity battery and strong 1800 W output (3600 W surge), it can run most household appliances and electronics without trouble. ￼ One of the standout features is how quickly it charges using multiple input options — AC, solar, or car — giving flexibility no matter where you are. ￼ The unit also includes multiple output ports, so you can power several devices at once, from phones and laptops to refrigerators and fans. ￼ The build quality feels solid, and the battery uses durable LiFePO₄ cells designed for long life, meaning this power station should stay dependable for years. ￼ Overall, it’s a well-rounded and powerful portable energy solution that I’d definitely recommend for anyone needing reliable off-grid or backup power.
