Update : neighbors with a similar apartment number cane to drop off package. Fedex driver thought He delivered to the wrong apartment after they marked it delivered. So they took it too another unit I really do believe they should make you sign for the package for something like this not to happen. The parcel driver was 100% wrong for doing that. I got to use it today and this generator is awesome. Does everthing i need it to do and it holds it’s battery. Besides the negative experience i had trying to contact support, the device itself is worth the price 100% . Original : Zero stars. For a package well worth over $800 They deliver with NO SIGNATURE required with Fedex? And when i check package is gone shortly after delivery time. Only person that appears on cam is the parcel delivery man. Order at your own risk. Thought these people would be smarter and require customers to sign

I have had the Delta 3 Max for a couple of weeks now. Charging from both wall power and solar panels worked fine, and the XT60i cable signaled the unit for higher current and faster charging. If you use a plain XT60 (no i) cable, the unit will only charge at 12V and a max of 8 Amps. Both AC and DC output ports work. I am puzzled why the 12V car plug was on the back with the other inputs, but not a big deal. I have not yet tested the USB ports. Construction is solid and I really appreciate the carrying handles on each end, much better than a single handle. During wall charging at 1700W, the fan did turn on, pulling air in from the front and out the back, but it was very quiet. You can watch battery temperature in the app, and in this case (70 degree indoors), the battery temp hovered around 100 degrees while charging and dropped quickly when done. The buttons on the front panel sort of blend in, so they are hard to find in dim light, but you can feel around for them and activate them The display shows which input and output ports are in use and the charge and discharge rates with time remaining. The app paired VERY easily to my Android starting with Bluetooth and then transitioned to my WiFi to complete the setup. I heard that you do need Wifi to complete the installation, so do initial configuration before you go off-grid. The app is qood, but does take some exploring to figure out the features. There are two types of home screens...the 'filling battery' and the 'power in / power out'...see which one you like. The description of station operating modes was a bit confusing to me. You can program min and max battery charge levels, as well as max input charting current for both AC and DC. I can connect to my power station using the app when away from home, but I'm not sure what IP path the communication takes. I suspect that the station is communicating to Ecoflow HQ, and the app is pulling the data from the HQ internet portal. It didn't seem to have any issues with my firewall.

The portable power station has been of great help to my family in Cuba, where blackouts are frequent. Thanks to their excellent autonomy, they have been able to keep phones, lamps and other essential equipment charged for hours. Its ease of use and the speed with which it recharges provide a lot of peace of mind in difficult times. In addition, it is a reliable and practical solution to have energy when you need it most. Without a doubt, it is an investment that makes a difference and that I totally recommend.

Without a doubt the best infrastructure boost I’ve added to my IT-scape and emergency readiness. Firstly the 10ms transfer makes my Delta 3 max and my Delta 3 classic a couple excellent UPS substitutes. I’ve got the classic on the PC and the WiFi modem and routers. I’ve got the Max upstairs doing the same thing. If we lose electricity we still have bulletproof WiFi and internet in the house. I’m thinking of getting another to power up the tvs and refrigerator upstairs in the event of another hurricane Helene or similar long term loss event. ALSO: The app and its storm guard feature are great. For once a company has put together a top quality system and a seamless effortless app for remote functionality as well as monitoring and status checks. I’ll never look back and will likely get another one. Hats off to EcoFlow. Excellent products.

I've been using the EcoFlow Delta 3 Max as a UPS for my setup, and it's been fantastic. We had a power outage during a recent storm shortly after I got it, and my entire setup stayed powered without interruption. If you're looking for a reliable backup power solution that can act as a ups for a desktop lcomputer, I highly recommend it.

I didn't want to get one of these. I really didn't. I got a generator for portable power. But this thing is a beast. It provides a LOT of power, for a long time. No, you can't pour a gallon of gas in it when it's empty, though you can charge it from your car (or a generator) Nowadays, we use this, and bring the generator as a backup for long days. (Haven't needed it--yet). Much bigger company than I realized. Far cheaper than the ones you see advertised all the time. Figure out your power needs, and get the next size bigger--or they sell extra batteries for each size system. There's even an app to control it. Just beware: Once you register, they will email you offers. A lot!

This power station has become an essential piece of gear on our film sets. I work in documentary production where we’re often filming in remote locations, and having reliable power for cameras, monitors, laptops, and charging multiple batteries throughout the day is critical. The EcoFlow DELTA 3 Max delivers exactly that. The capacity is impressive, it charges gear quickly, and it allows our crew to keep working without worrying about losing power in the middle of a shoot. It’s also surprisingly easy to move around set and perfect for working on the go when we’re far from traditional power sources. For filmmakers, photographers, or anyone working remotely in the field, this is a fantastic investment. It’s dependable, powerful, and has made our production days much smoother. Highly recommend.
