After 2 months of storage, I pulled in my refrigerator, fans, computer, TV and other devices during a power outage. I used it for hours cutting wood outside with my 18in electric chain saw as it was powering my class B motor home. It has changed the way I camp outdoors in my RV.

Always impress by EcoFlow as a product company coming out with new products. I purchased the Delta Pro through kickstarter and could not be happier with the purchase. Everything feels solid from the wheels to the suitcase style handle. Was pestimistic on the stoutness of the handle, but was proven wrong. Only complaint I have and of course knew this going in is the weight, 100lbs. Found it more challenging to move up and out of the truck. Other than that, no regrets!

This is an excellent option for emergency power or daily use. The unit is quiet and fast to charge with several charging options. Stand by mode works great for preserving the battery in case of power outage. The Lithium Iron Phosphate batteries ensure this will last for a long time. The portability of this unit means you can use this for home or when traveling. I got a few of the Ecoflow 180 watt solar panels to charge it with, which expands my options for any type of off grid or grid down situation. Overall a great product.

I received my EcoFlow Delta Pro about 6 months ago. It arrived well packed and in good shape, despite the outer box taking more than a few good hits. I’m very happy with the quality and functionality; when I get a second one, I will be able to effectively run the whole house, and with the solar panels be able to survive a grid-down situation. It’s heavy, but still quite portable, and the necessary accessories were all included. One thing I would like to see developed: to operate, it has to be in my garage where my breaker box is, exposed to less than optimal hot and cold temps. How about an insulated jacket with heat/cool abilities to keep the unit temp in a good range?

I bought the EcoFlow Delta Pro with extra batteries and a solar panel for emergency backup mostly but it has many other uses. Recently I had a faulty circuit breaker in my home that kept popping the circuit that powers my refrigerators and freezer. Having the Delta Pro allowed me to shut down the house power and work safely on the electrical panel and allow me to troubleshoot to find the faulty breaker and have it fixed. Had my two refrigerators, one 18 cubic, the other 22cubic foot, chest freezer and a couple of lights and a floor fan, all running about 10 hours of normal use, while I had my faulty breaker replaced and had the home service panel serviced for additional problems as well. Only used about 47% of the batteries total charge and probably could have run it the following full day before it would have run out of power. Could of use this unit last year when we lost power for three day in February in Texas. That was a long three days. Now I am prepared for future power outages. Attached are photos of how I set up my unit.

I purchased the Delta Pro as an emergency backup for regular outages. I have found several other uses and am very happy with multiple applications. I have used it to run a 120V wire feed welder. Because of its portability, I no longer have to run extension cords to areas several feet from an electrical source. The same goes for a portable compressor that I sometimes use in conjunction with a post pounder for fence repair. I have tried it on the camper and am preparing to head for the hills when the weather turns toward summer. I am sure that I will find many more uses in the future. I have recommended the Delta Pro to my friends and they are interested in my "adventures".

I have the EcoFlow Pro (two of them) for a few months now. Unfortunately, I had one fail on me just under 2 months. I sent in a request to have this look into and got help via email and eventually I had the unit replace with a repaired/refurbished unit. Not really a good sign with a flagship product in my opinion. Here are two list of what I liked and what I did not so far. What’s to like… • Clear display and easy to understand • Power storage capacity is large and still mobile • 30amp service receptacle (NEMA 30R) for RV easy use • Wheels and handle bar for easy moving around • The ability to use it in conjunction with smart home panel to power my home in a power outage and Time of Use functionality • The ability to use third party solar panels that I already own. What’s Not to Like… • If the unit fails in the inverter region… your dead in the water and the unit becomes a large expensive boulder. • The Pro Extra batteries cannot be charged or used independently on their own. In my case one of my units had a catastrophic failure and I couldn’t use the two extra delta pro batteries rendering the useless. • Cables to attach batteries to the main unit are a touch to short. • A bit off topic warranty registration is a bit confusing and you cannot review registered products. Overall, at the moment I am happy with my purchase and hope to use them in any chance I get. I also look forward to receiving my EcoFlow Wave that I recently purchase. One suggestion on this product. You should include the Delta max extra battery cable so it may be used with the delta compatible batteries. Or at the very least a easy way to find it for purchase on your website. It doesn’t come up under accessories in your main page, but if you google it comes up for some reason. Here is the hyper link address "https://us.ecoflow.com/products/delta-max-extra-battery-cable" where I found it today.

I've been using this battery backup for 6 months and completely love it. I originally purchased this model due to the huge amount of power that it can send out to all my gadgets. I WAS WRONG! This thing can handle much more. I can tell you that EcoFlow products are well built, solid and perform well. They separate themselves from the competition. You can ensure hours of power from this device without any unknown issues. Package shipped fast and after you charge it, it's ready to work. There is even an app. Put it in the back of your truck or car and charge all your devices in a snap. What more, it's simple. BUY ONE OR MORE OF THERE UNITS AND CHAIN THEM TOGETHER. MONEY WELL SPENT!

I received my pair of Delta Pros Feb. 2022 and they’ve been working remarkably. I use Odin and Thor daily and are being charged with 1.2kw solar array during day and the grid at night. Odin and Thor are connected together with the Double Voltage Hub and are mainly used for high wattage appliances and charge my Electric car- Fiat 500e. I’ve been very impressed with its reliability and ease of use. The app is well designed, making changes in its charging characteristics remotely is a plus! Online updates so far has been glitch free. In the future, I’m planning to add more batteries to this system increasing my capacity three fold. This system so far has cut my grid electricity usage by 1/3, saving $$$$ and going green! I’m a lifetime fan of EcoFlow and their products. Keep innovating EcoFlow!!!! Thanks for a great lineup!

After owning an EcoFlow R600 Pro when looking for a larger capacity watt hour power station and larger inverter my husband & I looked at all options available and selected the EcoFlow Delta Pro. Living in Florida we get lots of hurricanes and this power station was purchased to handle the power outages that happen. We've done a test run for a few days and we're all set when the power inevitably goes out next time. At the moment we're deciding whether to add on an extra battery to handle a longer outage. We've already purchased one EcoFlow 400W foldable solar panel and we're considering a second one as well. Living in a condo a solar generator fits the bill as gas & propane aren't allowed onsite here. Great product. Performs exactly as desired.
