Nice review, a couple of notes though. 1. In your capacity test you stopped at 5%, but you should have run it to 0% because the meters are not always entirely accurate. 2. With the external battery you can absolutely output a full 1800 W, even though the DC input is far less because the Inverter is running off the battery, not the input. 3. In your solar charging time remaining test, Yes, that meter is notoriously inaccurate but just because the controller shows input doesn't mean the BMS battery management unit is dumping that entire load into the battery. It's a pretty good BMS, it keeps track of the state of charge of the battery and there's no danger of it being fried because you left it plugged into solar panels really. The original Delta 1300 has been out for four years and nobody's had a problem with that. 4. There is nothing wrong with charging these batteries to 100%. For one thing, there is some battery reserve you can't see. But even top-of-the-line battery manufacturer Battleborn states there's nothing wrong with charging a lithium ion battery 0% to 100% and there is no memory effect. And for an occasional user, say someone who cycles it once a week 52 times a year, it will take over 15 years to reduce the capacity by 20% (800 cycles to 80%) and you will still have 80% capacity, so calendar aging will obsolete this device before battery cycling does. Now for daily cycling, it is better to buy a LFP lifepo4 battery unit which has 3500 cycles to 80%. But with these NCM units limiting charging 10% to 90% means you're sacrificing 20% of your capacity today, to save that same capacity in 15 years. It really doesn't make sense. It's better just to use it today. It's a great bang for your buck for the occasional user and look how much the prices come down in the last four years. But the idea that you have to sit there and monitor the solar input is overkill really. The BMS is smarter than you are and this is a peace of mind product, you don't have to baby it.
Ecoflow efficiency on most of their products is 78% Bluetti is about 86% VTOMAN is 85% most older Ecoflow don’t use Lifepo4 batteries so you’ll get 800 cycles to 80% or so they say but I’ve done testing that shows after around 800 cycles Ecoflow is at about 70% efficiency well built but I wouldn’t recommend it
It's refurbished because it uses cheap, high frequency, transformerless inverter tech. I wouldn't use one of these, even if they were giving them away.
It was out of calibration as it balances the cells in the final stage of charging. I bet if you charged it up again it won't take that long. It's usually around 10-15min while displaying 100% before it's done on AC and even longer on solar. The screen is an estimate and the efficiency depending on the rate of charge can be below 80% and is well documented.
Great deal. I had reached out to them right after the promotion ended and they were able to price match. Ended up getting one in new condition for 458 w/ tax. CS rep informed me that they guarantee their units have atleast 95% battery health on their refurbished items

I bought One New from Amazon on Black Friday with 5 year Warranty and 160 Watt Portable Eco Flow Solar Panel $705.00 and a refurbished Unit for $523.11 off Ebay with 2 Year Warranty and a refurbished Eco Flow 160 Watt Portable Solar Panel plus an Additional 110 Watt Panel and 2 year warranty as well and later a River Pro 2 for $250.00 off Ebay with a 5 year warranty and Bluetooth and App included. Very Happy with All 6 Items. And less than $0.50 Cents a Watt across the board.
Good review. One thing i would point out is that if you get their app you can set it to when do you want battery to stop charging. I set it to 90% if it's plugged in to solar. I had my river pro for over a year now and so far i am pretty happy with the company. I wish they expended the app so it had more customization but it's still good
Man this gives me some insight, I grabbed a power station on Amazon that was 2000 ish watt hour, but the display is just horribly violently inaccurate I have an in line meter showing the watts from my solar, and the watts it’s displaying is roughly 10 above the actual input Also the battery gauge is horribly far off from real life, says shit like 100% for up to 2 days of around 380WH The MPPT controller it uses seems to get absolutely ripping hot on the inside before the fans kick in And the worst part, the DC jack for regulated 6S lithium ion charging at 7.3 amp That thing if I rest the back of my fingers on it, it’ll arc the hair and give me a zap!! It was 1600 dollars with 250 off, for over 2000WH, which sounds good but keep in mind it’s lithium Ion not LiFePO4 All in all though, seeing that these things often have innacuracies in their displays calms me down Especially since I know the BMS kicks in and stops the charge, but I also know I probably shouldn’t take it for granted too much
I wish I could send you my battery to test. I got a smaller eco flow and it has a wonky AC output. When I plug in lights they have a tiny flash every couple of seconds. Wonder what's causing it
when you plug in the external nissan leaf battery, does it handle low voltage cut-off? will the ecoflow drain the external battery completely dead and ruin the battery?
I have a question for you, I saw it works for me I was wondering if you’ve tried since you’re definitely more of an expert on me on this front So i made a few XT60 series connectors when I was getting into soldering last summer I noticed if your solar panel voltage is so low that your power station input wattage cuts off at its full amperage (mine for example takes around 7.3 amp max) And my meter shows my panels only ever get to about 20V with full MPPT, but the station can take up to 30v MPPT So I put a large capacity 1S10P lithium pack in series with the panels to get significantly more watts just from adding the voltages I imagine it’s safe since the current is regulated, and the current seems to be entirely based on the solar panels ability to put out current, which I think is safely balancing the current from the battery pack, and according to my DC clamp meter, it seems to be true that the panels current will just follow what it can do, but also this strategy makes it so that when the solar watts drop below let’s say 20, if I leave this battery in series, it’ll continue to slow charge even when the solar input drops very low Obviously the aux battery is putting out very little current as well, but I was curious if you’ve tried this Mainly because of the concept of plugging your 40V of solar in, but you still have 35 volts before you hit your limit, so you could throw maybe even an 8S battery in series with the panels to get the most bang for your buck based on time Though I understand there’s a lot more hassle with plugging extra batteries and soldering connectors, I was just curious if you r tried this, especially since XT60’s seem to be so consistent with all these power stations at least internally

Hi first comment because of you im opening electric scooter now 😂
Great video, I have been looking at the power bank, glad to see you tested exactly what I was concerned about. Thanks Joe
Thanks.
Itsxa 3 year old design when you tested it. All of EF second generation units are top of the line.

This model can’t be connected to the app. It doesn’t have Bluetooth or Wi-Fi, thats one of the reasons it’s so inexpensive.

The charge controller, was probably set. For two hours. Of float time.
Connect it to an inductive load and then show us the waveform. Thanks
Thanks for the insight and for giving people a new, recent space to collect thoughts on refurbished products.
Do you remember seeing one of tjese battery banks that can accept 95v PV input? I have a TON of solar, but it's all high voltage.
Use a charge controller between your panels and whatever battery bank you’re using.
Were they running a promo? All I see currently is $599. Did they send you a discount and a coupon?
Yes, they were running a promo. If you don't need it now, just wait. They will run a promo once in a while.
Is the 12v output on the back regulated? If not you can see how much solar overcharges the battery.
The internal bms will disconnect and stop charging . The bms has overvoltage and overcurrent protection
thank you so much
would you be able to charge the ecoflow delta as well as the external battery with the delta wall charger?
I have a question for you, I saw it works for me I was wondering if you’ve tried since you’re definitely more of an expert on me on this front
So i made a few XT60 series connectors when I was getting into soldering last summer
I noticed if your solar panel voltage is so low that your power station input wattage cuts off at its full amperage (mine for example takes around 7.3 amp max)
And my meter shows my panels only ever get to about 20V with full MPPT, but the station can take up to 30v MPPT
So I put a large capacity 1S10P lithium pack in series with the panels to get significantly more watts just from adding the voltages
I imagine it’s safe since the current is regulated, and the current seems to be entirely based on the solar panels ability to put out current, which I think is safely balancing the current from the battery pack, and according to my DC clamp meter, it seems to be true that the panels current will just follow what it can do, but also this strategy makes it so that when the solar watts drop below let’s say 20, if I leave this battery in series, it’ll continue to slow charge even when the solar input drops very low
Obviously the aux battery is putting out very little current as well, but I was curious if you’ve tried this
Mainly because of the concept of plugging your 40V of solar in, but you still have 35 volts before you hit your limit, so you could throw maybe even an 8S battery in series with the panels to get the most bang for your buck based on time
Though I understand there’s a lot more hassle with plugging extra batteries and soldering connectors, I was just curious if you r tried this, especially since XT60’s seem to be so consistent with all these power stations at least internally
