Very powerful. Runs everything I need it to run. Very nice made.

We purchased the Delta Pro 3 to run our well pump.

Came with no package damage and after setup worked fine

I’ve done some testing on this one and it’s pretty remarkable.

>$500 more than what you can purchase this on the manufacturer's website - I thought Sams was the place to find the best deals.

The price is right, they are a must have item. Buy two or three for around the house.

Bought the Delta Pro 3 and an extra battery. The battery connected to the Pro 3 with the included cable easily and they synced right away. One battery doubles the capacity of the Pro 3. It is a little heavy but the handles make it easy to carry. It uses a proprietary cable for the connection but it seems very sturdy. I will likely add a second extra battery in the future. The Pro 3 seems very solid. It came on right away and charged easily. It has plenty of outlets. I already have a manual transfer switch in my house so I connected the 240 outlet to it to test it out. The Pro 3 (with one extra battery) ran my full sized side by side fridge for 2 hours and dropped from 90% charge to 86% charge. The maximum charge rate from using the wall plug is 1800 watts per hour but you can use the phone app to reduce that. I set it down to 1200 and it worked perfectly fine. The manual says you can charge it at 240v 3600 watts but I haven't found any way to do that. The manual is awful. Literally just a sheet with a couple of pictures and a few sentences. Hey, Ecoflow, you really need to give a better set of instructions for your device because the unit itself seems amazing. They show a variety of ways to charge the device but a lot of it is things like solar panels or car chargers. If you use a regular generator you have to use the standard wall plug which maxes out at 1800 watts an hour. Hey Ecoflow - I have a generator with a 240v outlet. Give me a way to plug it into the Pro 3 so I can charge at 3600 watts an hour please. Warning, the Pro 3 can connect 2 extra batteries OR 1 battery and 1 Ecoflow Smart Generator, but not both. The Smart Generator uses the same plug and connection site as the batteries and the Pro 3 only has two of them. With 2 batteries installed you have to use the regular C20 connector (Standard wall plug) to charge the machine and you lose the "Smart" connection. Ecoflow - please either put two plugs on the battery so they can be connected together, like the Pro Ultra. Or, make an adapter that lets the Smart Generator connect to the left lower AC Inlet plug, so I can have 2 extra batteries AND use a Smart Generator with the smart functions intact. Overall it's a nice piece of equipment. It's perfect for short power outages, even with it's given limitations. It's the best on the market at the time I write this review. But, if you are looking for a whole house backup with really large capacity I would look at their Delta Pro Ultra instead. But this will be more than enough to get me through an overnight power outage.

Perform better that i expected ;0 it powers the house with no problem, I love it.
