Great device, a few limitations

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.

Purchased two dp3’s and two extra batteries. Best working performance on the market. Both were delivered with non-working extendable pull handles. They need a new source. Imagine having the top of the line suite case and you can’t pull it behind you. Or, you can’t store it because it does not retract.

I found the Delta pro three to be a very good solar generator with one exception I would, suggest to buy two 400 W panels because I found that the charging capabilities are there without the additional solar panel it charge slower than I would’ve liked it to

Works great but could use a light to see buttons

I’m happy that the DELTA Pro 3 works exactly as advertised. The only difficulty I encountered was when using it at night in my camper i had to get a flashlight to see the buttons and the ports. A backlight to the ports and buttons would have made it easier to use.
