Large capacity and lots of ways to use it

I purchased the Delta 2 Max as a bundle with two solar panels included. Unfortunately, the solar to XT60 cables to connect the panels to the battery were not included in my shipment. I had to wait for those cables to arrive before being able to charge the battery. I also purchased a Wave 2 air conditioner to be powered by this battery. I did not know that connecting the Wave 2 to the Delta 2 required a proprietary cable. That cable was out of stock on the EcoFlow site, but fortunately I was able to find one on another site.
Once I had all the necessary cables, I was genuinely pleased with the performance of the EcoFlow solar panels and all the charging information available in the EcoFlow app on my phone. In addition to the EcoFlow panels, I had two solar panels purchased from a competitor on the second solar input (that also required an Andersen to XT60 cable, but I was prepared for that). This greatly sped up the process of getting the battery to 100%.
With a fully charged battery and all the necessary cables packed into our camper van, my wife and I were able to test the battery and AC combination. My hope was that the Delta 2 Max would be able to power the AC for two nights in Eco Mode without a recharge, but at the end of the first night, only 20% of the battery capacity was left. Admittedly, it was very hot and humid (80+ degrees at night with 90%+ humidity), and I think under less harsh conditions my two night goal can be achieved.
The Delta 2 battery has enough power outlets to run everything I can fit in my van. I look forward to having this battery along on my camping trips for the next several years. If I do have to up the capacity, it's easy enough to add an extra battery. I just have to remember to order the proprietary cable to go with it.

Instead of a natural gas monster, go DELTA 2 Max!

I was looking for a way to keep a few key appliances powered in case of a limited power outage (which happens in Houston TX WAY too often!!). This is the perfect solution. I added the 2x solar panels and have charged the power station completely with the sun. I also love the app and connectivity that makes managing the station a breeze.
A great solution!

Delta 2 Max Pressed Into Service Unexpectedly
on July 19, 2023

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.

Excellent Product Delta 2 Max

I recently purchased the EcoFlow Delta 2 Max to use as a Emergency Home Backup in case of power outages here in Florida from Hurricanes or storms. The unit is very well made with 2kWh, expendable to up to 6kWh, it is very quiet unit and has LFP Battery Chemistry. I highly recommend purchasing this unit either for camping or to use as a Home Backup in case of power outages to power your refrigerator, microwave, blender, coffee maker, washing machine, etc. The unit has the latest technology to recharge quickly and has a long lasting time span of about 10 years.

Great for overlanding

Have had this for about a month and a half now, charge is extremely quick when plugged into AC. Charges decently fast when hooked up to solar, I have a combined 720 watt input. So far everything seems to be operating correctly, I did have one issue where it dropped its Wi-Fi connection and I kind of had an issue getting it reestablished. I reached out the service and they gave me some ideas of how to get it to work again, I got it to work again. I do have two extra smart batteries attached to this Delta 2 Max. With everything hooked up it does take quite some time to charge on solar. Which is to be expected though it has to feel quite a lot of power reserve. This will come in handy when the power goes out and I need to maintain critical items in my home. All in all I think it's probably a great product, only time will tell though.

Just what I wanted

I had been researching portable power systems for some time. My specific use case was for extended off-grid camping, with the ability to charge from solar or AC (when available) I also wanted to be able to use it in a limited home-backup role for powering critical items (refrigerator, freezer, etc) during power outages at home. The Delta 2 Max ticked all the boxes. With the ability to expand up to 6KWH storage with the extra battery packs, it could serve this secondary role very well. Thus far, very please with the purchase, and support from a very active user community. Two thumbs up!

Worth the Wait

I've been researching this type of product for over a year. The Delta 2 Max has all the features I was looking for. Long battery life, quiet, reasonable weight and good price. Would have bought the Pro, but a little heavier than I wanted. Will use for power outages and not for daily use. I've only had for a few weeks, but am very impressed by the build quality, functionality, quiet operation, and ease of use. Also bought the 160W solar panel. It works quite well even though one panel will take some time to recharge the unit. There are several other charging options which makes this so versatile. It gives me great peace of mind knowing I will be able to use some home devices during a power outage. Will probably add a second battery at some point. Very pleased with my purchase!

Pretty good product for on peak power shifting

I got this to help shift my on peak power usage during expensive summer pricing. I have my refrigerator, router, tv, surround sound system, and a few lights plugged into this 24/7 and it powers them no problem. The fans are relatively quiet and the app makes it nice to check info about the unit. My biggest complaint would be solar charging.expect about 50-75 watts to be wasted in ac-dc conversion so if you get 200w solar you are actually only charging about 125-150. Other than that it’s a great unit and charges fast via AC wall outlet. Haven’t taken it camping but it can also be used anywhere since it’s only about 50lbs
