How many percentage points does your Delta drop after boiling roughly 1L of water? I need to do more testing but I think my Delta 2016wh is giving me closer to 1400wh than 2000Wh.

My Ecoflow Delta Mini at 882Wh is pretty spot on
I get 4hrs load shedding cruising at a steady 200 Watts on the display
My SOC is set to 0-100%

Maybe I just need to calibrate the battery and test again.

I tried to drain it to 0% but it stayed on 1% and after some time it switched the AC outlet off. It stayed on 1% and I tuned the AC outlet on again, tried to draw more power from it but it switched the AC outlet off again (the rest of the unit stayed on) and it still showed 1% remaining. Is this normal?

Yup mine does the same
I just ignore it
Common Ecoflow problem
Dont trust the display at all
Tunes me remaining is 1 or 2hrs but it will run 4hrs

Yeah, I watched his review and he says he's not sure, and no amount of Googling seemed to help so I put it down as a ? under its chemistry.

Is this the EB240 you are referring to:

Yes (unless there's another Bluetti EB240 model that exists). Hobotech points out that they may not be Lifepo4 but a different solution used in a certain brand of electric cars. Can't remember what, it's in the video on YouTube.

Hmmm those ussally are rated for 500 or 800 cycles.

So this is the problem: I don't think NCM can do 2500+ cycles, which is why I'm more inclined to believe this is some sort of error. Also, the US site doesn't make any mention of the battery chemistry. It would be strange that most other NCM units are 500-1500 cycles for NCM and these are somehow magically 2500+.

Isn't it NMC?

 

[Park@82]

Isn't it NMC?

EcoFlow also states that they use NCM on their first gen products. I've tried to find the difference but some say that they are exactly the same thing while others say that NCM is safer than NMC. I'm still not sure.

Maybe its only NMC that catches fire so they change some letters around and call it "safe"?

My Ecoflow Delta Mini at 882Wh is pretty spot on

My SOC is set to 0-100%

I was using a smart plug to monitor usage (in Wh).
But I noticed now that the plug shows different wattage being drawn vs the EcoFlow display. I'm not sure which one is correct.

With my TV and streaming box the plug reported 65w being used while the EcoFlow showed 77-78w.

Then I plugged in my airfryer and the EcoFlow reported around 2250 while the smart plug showed around 2350.

Edit :
I'm currently leaning towards the EcoFlow being correct even though I've tested with 2 different smart plugs. My airfryer is rated to 2225w and the EcoFlow was the closest to that.

Made in China.

As is everything. xD see edit above.
Edit: apparently my airfryer was made in turkey

see mine

LOL @wingnut771
EVERYTHING is made in China these days
And I mean everything
I was in Germany in 2017 for training at the most elite camera and lighting company in the world and I though German Engineering all the way Nope, everything is made in china. The Germans only assemble everything LOL
What an eye opener that was to see it first hand in the "factory" (Assembly line)

Yeah, China have the police to guard the companies incase any of the workers escape. Shareholders love that because its good for the bottom line.

Dumb question for those with the EcoFlow devices,
Which one of these would behave like the Ellies 720W / 1200VA in terms of being able to actually play PC games for an hour and a half with no issues ?
