Edit: it says Ebay refurbished but still list the accessories in the product description
Here's what I did.
1. Message EcoFlo cs through eBay. Asked if they were having a sale on the delta 2 (refurb) anytime soon.
2. They responded with an offer of $719 (about $100 off).
3. Accept the offer and then add code REFURBSAVINGS which brought my total down to $674 w taxes

Hi there,
Sorry for the confusion caused.
Please kindly note that the solar charging cable is not included in the power stations,
but in solar panels due to products update.
We have attached a picture of the item in the box. Please check it.
However, We have arranged a shipment for the solar charging cable since you are our valued customer.
The tracking number will be updated for you later.
Best.
-------------------
The issue was that it is listed in the production description and the included service manual. There has since been a revision of the manual on the website.

I plugged in a heater set to medium mode at around 900W load and got about 89% of its 1260Wh rating, which is fantastic considering inverter losses. This was on a brand new EcoFlow Delta. I'll test my dads "refurb" tomorrow and see.
Edit: I hooked up the Vornado heater to the Kill A Watt and couldn't really fine tune the load. KAW Meter says 1380W and the front panel says 1401W. What am I looking for to figure out the capacity this unit has (like how many cycles it has gone through already)? How did you get 89% from your numbers, sorry I'm a noob

But basically I would first try to dial down the heater to a lower setting, because 1400W is pushing it pretty good. I set mine to about 930W.
The Kill a watt meter should have a button that says Kwh, which keeps track of Kilowatt hours of energy used. The trick with this however is you kind of have to babysit it and watch the screen especially near the end, because it will shut power to the inverter and zero out your Kill a watt meter.
In my dads case he got 1.05Kwh and my new unit tested out at 1.12Kwh. In my case at 1.12Kw I divided 1260 by 1120 to get my ~89% figure. I would say anything in the 87-90% range you are at 100% +/- 2% or so of original internal battery capacity.
I also recommend doing the calculation based off of time and average power draw.
So take for example the heater runtime and divide by 60 to get time in hours. So 1.1 hours for example. Then take your average power draw (average what the ecoflow says and what the kill a watt meter says). In my case if thats like 930W average I'd do 1.1 hours of 930W = 1023 Watt hours or 1.023Kwh in this example. Internal battery when new at 0.2C (5 hour discharge) is rated at 1260Wh. But there are inverter conversion losses and inverter/fan losses so you'd expect at most 90% of this figure.

1. Charge the unit to 100%
2. Hook up heater to KAW meter to unit & try to run at 900W
3. Let it run & monitor the KwH value on KAW meter and note the last value before it shuts down
4. Take value in 3 and divide by 1260Wh. The closer to 0.90 it is the less it has been "used"
Edit: I ran the test tonight with the Kill A Watt meter.
I charged the unit to 100% and then unplugged the power cord. Hooked up heater to the KAW meter and ran it in low mode, averaging 687W. The unit shut down around the 92 minute mark and the KAW recorded 1.06kWh. So 1060/1260 = 84.1%, is that "bad"? I know there's loss due to the AC inverter, fans, heat, etc, so you can never get the full 1260 capacity, but what is the typical efficiency for this unit?
Also what concerns me is the "estimated" time and percentage remaining on the front panel. When I ran the test above, the estimated remaining time dropped to 1 minute and remaining percentage to 1% after around 60 minutes, then it ran another 32 minutes before the unit shut down! Is this unit messed up? Or it just needs to run more to get calibrated? It sucks that I won't know how much is actually left even if the 84.1% efficiency I got is good.
Edit 2: ok I googled for inverter efficiency and 84% is normal. This link mentions 65-85% is typical. And the more the load is the more efficient it is. So you had your heater at 930W which is higher than my 687W so I guess your run is more efficient based on that observation.

The Delta 2 efficiency is lower apparently at 80%. And this review says it's more efficent the smaller the load 🤷🏻. It also mentions to charge and full discharge to calibrate the estimation values on the front panel
https://www.pcworld.com/article/1...eview.html
Edit 3: yeah my unit needs some sort of recalibration. I recharged it after running the above heater test and it hit 100% with an estimate of 1 minute left after 40 or so minutes and then it continued to charge at 798W for another 30 minutes before it completed. Anyone knows what are the steps to recalibrate this. This lines up with the behavior I described above when it continued to run for another 30 minutes after saying 1 minute (1%) left
