This thing is the size of a car battery but does so much more than that
Edit: I have to source an proper Indian power cord from one of my spares to properly charge from mains. Please do not use the US socket as it flips the terminals and might be a problem. I am knocking an star for not including a proper power cord.I bought this to specifically to escape APC’s intentional hidden 2 year battery subscription plan. even the expensive ones do that. (i want to rant more but i value your time)600w is the perfect limit to handle my pc and it does it without a sweat, handles surge of my 1000w PSU and occasional nasty GPU spikes very very well with “absolutely” no flicker on my mood lighting never seen my 2800 optimus luminous inverter or main grid being this stable. this is simply on a next level in terms of AC power delivery. battery life is also solid and predictable i was able to extract around 500wh which is actually almost half of my main inverter setup(2x 12v 150ah Lead acid batteries). Never had weird shutdowns or glitches during switching in river 3 Max while gaming comparing to my previous APC which is basically a roulette (The waveforms speak for themselves honestly)extra battery makes it a perfect Spherocube ( Dice shaped) and it’s filled with very functional, feature packed ports to the point it actually decluttered my desk. I also use the DC in port to get free runtime of avg 500wh per day using solar.and it does all these things while barely audible compared to my split ac ( just a minor buzz )overall i am truly flattered to see such a well made well engineered product in 2026. about time <3

Device is excellent and works amazingly.Quiet enough for use at night though the fans do turn on and the screen does too.Took this out on a boat overnight this summer for a CPAP and was able to use it with humidifier and heat in the summer all night long while also charging my phone.Great size and efficient to use. Charging the battery was very quick during the day from a generator too.

UPDATE 2: I’m happy to report that the unit performed perfectly during a seven hour long night of astrophotography using both types of DC outputs (cigarette lighter and DC5521 port) to run both the telescope mount and wireless control unit, including dew heaters. The gear used up 40% of the capacity, consistent with the reported output wattage. In addition, EcoFlow has followed through on sorting out the refund on the original unit as promised. So, again, very impressed with their customer service and definitely can recommend dealing with them!UPDATE 1: I am updating my review based on a couple of weeks of interaction with EcoFlow’s customer service. After being quickly contacted by them and walked through some troubleshooting, I was asked to return the original unit for a replacement. This proceeded relatively smoothly and a new unit eventually arrived on my doorstep the other day.I am very happy to say that the DC outputs on this unit work as expected; where the original unit showed OVERLOAD and shut down, this one powers my astrophotography gear properly with no such issues. I will put it through some overnight imaging testing within the next week or so but I have every reason to expect that the unit will perform as advertised and expected. I am looking forward to using it for many years to come!A BIG shout out to EcoFlow’s customer service – they were unfailingly polite, responded rapidly, and “made things right” as they worked to resolve the issues I was experiencing. Once the remaining charges on my card are resolved (and I have properly night-tested the unit), I anticipate updating my rating to 5 stars to reflect their helpfulness and the products’ capabilities.ORIGINAL REVIEW:This unit was purchased after a fair bit of research and comparison to similar units by other manufacturers. It came well packaged, charged VERY quickly, is surprisingly compact and portable and has an extensive feature list including an app which connects to the unit & monitors/controls it. It was purchased with the intent of using it to run an astrophotography setup from the DC outputs. I’ve used other brands’ smaller capacity units to do this without problem and looked forward to the larger capacity and extra features this unit advertised.This is where the issues arose. Immediately I ran into OVERLOAD messages & disconnects when using either of the DC outputs. These should be capable of up to 3A at 12V, but despite my device(s) drawing only 25 W the unit would consistently shut down with the OVERLOAD message. Thinking that my heaters were potentially causing current spikes beyond the 3A limit, I used the cigarette lighter output (which supports 8A) but again, same issue. The unit SHOULD be able to handle 100W+ on the DC outputs but I could not get my 20-35 W to function. I was able to use an AC adapter from the AC outputs to run one of the devices without problem, but that requires using the adapter (rather than just a DC cable) and the inefficiency of converting the battery to AC and then back to DC again; run time was less impressive as a result.I don’t know if this is typical or if I have a defective unit, so further investigation is warranted. I DID update the firmware to the current version but it did NOT help with this issue.

I love this new gen…the new design is more compact. It’s lighter and the fan is not as loud. I like how the handle is located on the side creating a flat top so it sits in my vehicle easier. Build quality is fantastic and its solid. Definitely feels high end.It works as an ups “they call it ems” just fine with my m1 iMac. I also tested it with my pitching machine… no problem at all. I’ll definitely bring this to my practices. Can’t wait to use it to camp in the summer. Faster charging means a lot to me as my kids can drain the power station pretty quickly…Overall a awesome product to have and I highly recommend it.
