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. 💪🔋

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.

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.

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.

Style: DELTA Pro Extra Battery
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.
