The rating of 2 kWhr is really 1.4K-1.6 kWhr for the following reason: 1. To maintain good battery life, one should not discharge the battery below 10% or charge above 80% for normal operations. This is normal Lithium Ion battery behavior but specmanship means a lot of manufacturers ignore this constraint. They should just add 20% more battery and adjust the software to avoid the corner cases of Li-Ion chemistry, but most do not. Ecoflow is no exception, unfortunately I'm also unable to set the maximum charging level automatically to 80% while using as a UPS, so I have to tediously monitor the charging level to avoid the 100% charged which the manual recommends not doing over long periods of time. There should be a built-in "extend battery life" feature to make this automatic. Humans should not be in the loop to save battery life. The UPS mode cuts out for a half cycle (30mS) which some equipment can handle and some cannot. Please figure out how to make this device a 100% useful UPS in the future. In general a primary use case of "leave it plugged in in case of a power outage" seems to be somewhat neglected in the documentation and feature set. Please elevate this to a primary feature. An Ecoflow that has self-discharged to 25% when set in the corner for 2 years unplugged is of no use in a power outage. Equally an Ecoflow that has damaged the battery because it was left plugged in for 2 years in the corner is also of no use in a power outage. There isn't an automatic way to handle both these constraints, it requires a human in the loop. Most humans, especially me, are terrible at such tasks, but computers are great at such tasks.

I’m very satisfied of my Delta max 1600. I used it for Back up Ups to my Security alarm and internet modem and router in case of emergency. I’ve been getting a lot of blackout around my area and was able to continue power some of my electrical equipments. No problems yet on the ecoflow Delta max 1600. Thank you so much!

Hello shoppers, what we all know is that the cost not cheap. However, the buck is on you, to set your destination for what comes your way. So, on that point I can say, this generator is a Hot product for the buck and worth it and we can hope as for the future that this will last for whatever use. Have a safe journey.

The delta max is a BEAST!! Used during an 8 hour power outage in my neighborhood. Delta Max worked like a charm. It powered my full size fridge plus big screen TVs, internet and modem all night long. Would love to get the extra battery for the Delta Max someday.

This is my second Ecoflow. I love their generators they are very dependable. I will be purchasing another one in the future. Also their customer service is great. If you have any issues-they will get back to you in a timely fashion. They will also do everything they can to resolve the issue.

It would be nice if the instruction manual incorporated larger diagrams on features of the unit and explain all of the operating modes.. I have yet to figure out if app that controls the unit can actually turn eco flow on or off.. I intend to use it in a small airplane- remotely mounted from the pilot position..

Great product,but was overpriced on the item and nothing could be changed cause was over a month😔 that I had it. Wish a bag came with all products like they used to include. Overall has worked fine on performance and use. The weight is not to bad but is heavy if you have a bad back or shoulders. Could move around on a dolly if needed. Eco flow did keep in contact with me via email. Great on the go for 2 day travel and having enough power for phones tv,DVD player and speakers. Or for a movie projector to run❤️

Understanding that not every customer is adept at power stations and create the manual as such would be helpful. Also, the print is light and small, also not helpful I like the design of the Power Station having handles on each side. At 48 pounds it’s pretty heavy for me but the handles make it easier to lift. I did buy a plastic moving dolly with swivel casters.. I keep it on that so I can easily move it around when needed. I haven’t had to use it yet but I imagine I will this winter as my area is prone to power outages. Fingers crossed it’s as powerful and dependable as people say.

My only complaint is there is only one 12v dc car port. To be most efficient, I want to run as many dc appliances as possible. Instead I have to run the majority of my van through the inverter which consumes additional power. I would want a minimum of 3 12v dc car ports.

Extremely well built and highly useful layout for all the outputs as well as the inputs. The App is fantastic for device management and monitoring. Perfect unit for a power failure or off grid situations because it can handle just about anything you throw at it.
