The standby power consumption is very disappointing. Just having the DC on with no load apparently takes 10w! Otherwise I like the product.

Delta 2 Max Does What I Want it to Do

I haven’t had the delta 2 Max for very long so my review won’t be as in-depth as I would normally do. I bought this unit to run my 1000w microwave during nighttime (when my household solar is not active) plus as a battery backup in case of power outages. It runs the microwave with ease and I have no doubt it will run my pellet stove for quite some time if needed. I’ve charged it both off household electricity and solar panels with no issues.
My one real complaint is, being this large of a unit, I would think that most people will use it for AC power (I could be wrong). But, the main power button, as well as the screen are on the opposite end from the AC and charging sides. However, if you are charging a phone, hey, you can watch the wattages output, the time it can hold at the power drawn and other info from that same end. It’s a minor quibble, but irritates me.
Another irritation (and they all seems to do it), is to have a black package with dark gray writing. I can’t see that with a flashlight and readers. If there were more of a contrast between the colors, I’d have a fighting chance. But again, all 3 of my battery stations, from 3 different makers, are like that.
I rated as 4 stars instead of 5 because I haven't had this long and they are sort of expensive. I haven't found any flaws yet.

Delta 2 Max Pressed Into Service Unexpectedly

I had just received my Delta 2 Max (D2M) a week before we had an unexpected and unexplained power outage. It was right at dinner time as food was going into the oven. Fortunately I had the D2M at the ready and routed a 20-amp power cord from the D2M to my transfer switch. We were able to run the 1700 watt toaster oven for approximately 45 minutes along with lights, computer, a refrigerator, and a freezer. This drained the battery in the D2M to about 30%. I had also recently purchased the EcoFlow Dual Fuel Smart Generator (DFSG) and hooked it up to the D2M to give it a test, too. It came on right at the 30% mark I had set in the EcoFlow app. It took about an hour to charge the battery with propane. The generator then shut itself off automatically when the battery was fully charged. Dinner was served and power eventually came back on a few hours later. Both the D2M and the DFSG performed as expected with no problems. I highly recommend this set up. Before I would have to run my gasoline generator continuously during an outage. Even though it has an ECO mode, it would still burn 3-4 gallons per day. With the DFSG and a Smart Extra Battery (SEB) I will likely only need to run the generator 2-3 hours per day, and that can be reduced with solar panels. NOTE: I prepared for this EcoFlow setup by drilling a hole in my exterior wall. This allows me to keep the D2M and SEB inside but connect them to the generator, transfer switch, and solar panels outside. The PVC conduit has caps when not in use.

This Delta 2 Max is all you need for all those road trips or at home for any electrical emergency. I am really impressed with this product,
but you will say that it is very expensive, and yes it is expensive but when you have it you will say that it is worth it because it is very efficient and durable that it comes with a 5-year warranty, just enough to get more for your money, thanks

I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.

24/7 power supply in our RV!

Bought the Delta 2 Max at time of product launch with 2x110W foldable solar panels and cannot be happier!
Charging is quick via power outlet but I decided to change default setting to 400W input to avoid the cooling fans from turning on. Fans do not turn on at this setting and unit is extremely quiet.
It fits perfectly in our RV under our dinette table. It connects to our RV power cord and we are able to use all our appliances at any time of the day. In the past we had to run our generator when boon docking and limited to park hour rules.
Very efficient 110W solar panels (2x) put out > 200W/h in full sun and are capable to keep our unit charged. Even on cloudy days it charges > 50W/h. Impressive! I made a pvc stand to mount the panels for ease of following the sun.
I wish the solar cables would have shipped as part of the bundle I ordered. Customer support was very fast to respond to my email and cables were shipped next day.
Love the EcoFlow app. It allows me to control everything without the need to crawl under the dinette table! App is very user friendly and very fast to connect whether via Bluetooth or WiFi.
Overall, very happy with our Delta 2 Max, the panels, packaging, app and build quality!
We plan to use it as a backup for power outages to keep our fridge and wireless running at home.
