Excellent Portable Power Station — Powerful and Reliable I’m very impressed with the EF ECOFLOW DELTA 3 Max. It has plenty of power for running multiple devices and appliances, and it’s great to have around for power outages, camping, road trips, or job sites. Charging is fast, the display is easy to understand, and the unit feels solid and well built. I especially like having the peace of mind of knowing I have reliable backup power when I need it. Despite its high capacity, it’s still convenient enough to move around and set up. Overall, a great investment for anyone looking for a dependable and versatile portable power station. Highly recommend!

I bought this for my parents to have as a backup because they experience frequent power outages where they live. I really like the capacity, how easy it is to use, and the fact that they can connect several devices to it at the same time. The design feels solid and well made. It is quite heavy, but it does what I bought it for and gives my parents peace of mind during power outages. Our plan is also to recharge it with a solar panel system so they can keep it charged for most of the day. Considering how useful it is for my parents and everything this unit offers, I think the price is reasonable. Overall, it has been a very good investment, and I’m very happy with the purchase.

I'm a big fan of the ecoflow products making this my 9th portable battery from ecoflow. The delta 3 max is my biggest battery so far. I can say that with the 2kw of battery and 2,400 watts of power your not gonna have any problems powering up things. I tested it out on my iceco VL45Pro fridge and it kept it going for a little over 5 days with it set at 36 degrees. Still need to test it out on my big fridge freezer soon. My only con is that I wish it had a 140 watt USB output along with the 100watt USB.

This EcoFlow power station is simply top-notch. What impressed me the most is how incredibly fast it charges to full capacity—it's super efficient. On top of that, the battery life is amazing and keeps my devices running smoothly for a long time. Absolutely worth every penny, 100% recommended!

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.

Have used this power station to help with family dessert business. It powers a waffle iron and a freezer or two. The surge is a tank, and can run in surge power for several seconds. 2400W continuous is where you want to be with this one though. The location of the cooling vents is at the top front and rear of the unit. This has allowed me to run this in many situations without ever having to over-worry about ventilation paths. The engineers did a really good job with this design, as most the air exchanges near the protected handles with plenty of room. 48lbs makes this unit hefty, but not unbearable. Thanks EcoFlow for this versatile power station and the hand truck they included to increase its portability.
