EcoFlow Delta 1300 Portable Power Station, Backup Systems

Updated review (added a star) with a better (but not perfect) outcome. Falls short of five stars. After my unit failed in month 12, and after I made an appeal based on fairness, I received a new replacement unit (rather than a reconditioned unit). That is great and much appreciated, however I understand the warranty on the new replacement is not two years as was the case with the original unit. Rather it is one year - the remaining warranty period on the original purchase. Either you believe in the quality your product or you don't. Great customer service though. My love affair with Ecoflow has ended.

Delta backup I purchased a year ago failed, and the best Ecoflow can offer is a reconditioned replacement unit (of un specified age and condition) and the remainder of my warranty on the original unit - a year. If the replacement, reconditioned unit also fails within that one year period, I assume I will get the same treatment, even if the remaining warranty is only a few days or hours. And if it fails after a year, I'm just out of luck. On the plus side, customer service is responsive and helpful, they just don't have a very good story to tell. Next purchase will definitely be another brand - Jackery gets high reviews.

This is a purchase I didn't want to make but am happy I did. Since before the big covid shutdown of America happened, Southern California Edison has been having many, many "planned power outages" in my neighborhood. In the last two weeks alone we've had 3 "planned" outages that start in the morning and continue through the afternoon. I've had to replace my garage refrigerator, repair our main refrigerator twice, and got sick of having to leave the refrigerator doors closed until the power resumes so all our food doesn't spoil. After many, many of these "planned," and even unplanned outages, I finally broke down and paid for the Ecoflow Delta. Although more affordable, a gas powered generator wasn't a good option for me with the weight and having to carry it up ... MoreThis is a purchase I didn't want to make but am happy I did.

I've had to replace my garage refrigerator, repair our main refrigerator twice, and got sick of having to leave the refrigerator doors closed until the power resumes so all our food doesn't spoil. After many, many of these "planned," and even unplanned outages, I finally broke down and paid for the Ecoflow Delta. Although more affordable, a gas powered generator wasn't a good option for me with the weight and having to carry it up stairs by myself, not able to store inside the house and the noise it would produce for hours while in use. I charged the Ecoflow to 100% and when the last "planned power outage" happened again, 3 days ago, I rolled our full sized refrigerator out from the wall and plugged it into the Ecoflow, it worked perfectly. Now the heat of summer in So. Cal, while the power is out for hours and hours, won't effect our fridge anymore. We can even open the door and access our food and drinks while the power's out. I did my homework and made sure the wattage was sufficient for my needs and I'm happy with the product. Wish I didn't have to buy it but So Cal in my neighborhood is beyond ridiculous and I just had to break down and invest $1000 into the unit. It was sold through Let's E-Bike but was Ecoflow themselves that shipped, both Let's E-Bike and Ecoflow did a good job with everything. I've only used Ecoflow once so far, but so far so good!

I purchased a Delta unit to use it as a UPS on a wood pellet stove and it does the job perfectly. If our electric utility goes down during a storm the fire can go for 24hrs plus and we have lights and can charge phones etc, love it! NOTE: I have made sure the pellet stove metal body has its own earth bond wire; a copper wire connecting the stove case to a house earth point. This prevents any static discharges making their way back to the Delta, this is important because the Deltas outputs are not grounded. The quality of EcoFlow hardware is high, the case and handles are an indestructible nylon like material. My wife has no problem carrying it as the handle design allows her to keep it close to her body for lifting. I love the user interface design as well, it ... MoreI purchased a Delta unit to use it as a UPS on a wood pellet stove and it does the job perfectly.

I love the user interface design as well, it really feels like a futuristic piece of kit, to have such a pretty thing be so robust is great. The charge rate using AC 120V power is incredible. It can charge in less than an hour from empty. This is a massive PRO for us... it means we can run a generator for about 1 hour in the day to fully charge it, put another way... one generator tank can give us well over a week of clean 24/7 power, it's awesome! I plan on buying a couple of EcoFlow foldout solar panels as well to venture into the world of solar, I love the idea of no gas needed!

Got this unit free from Pacific Gas Electric (PGE) about a year ago on their medical baseline program since I use a medical CPAP machine for my sleep apnea medical condition. Because I live in the Sierra Nevada mountains PGE periodically shuts power off during high winds to minimize wildfire potential caused by trees falling on their electric power lines. So they gave me a free 1260Wh EcoFlow Delta unit so I could still use my CPAP when power goes off. Nevertheless I want to assure the reader that this is an independent and unbiased review because PGE is not the manufacturer, and I was not enticed nor requested by the manufacturer or PGE to write this review. I'm just really happy about this unit and want to share my experience with others.

So they gave me a free 1260Wh EcoFlow Delta unit so I could still use my CPAP when power goes off. Nevertheless I want to assure the reader that this is an independent and unbiased review because PGE is not the manufacturer, and I was not enticed nor requested by the manufacturer or PGE to write this review. I'm just really happy about this unit and want to share my experience with others. MY REVIEWThis EcoFlow Delta Power Station is a fantastic unit. There are so many positive features about it that I could address but in this review I'm just going to focus on one area (you can read the specs for all the other features). What really stands out for my use is the 1260 Wh total energy rating, the 1800 W continuous power rating, and 3300 W surge rating (to handle high in-rush current devices). With these ratings you can plug in high current devices like coffee pots, toasters, microwave ovens, vacuum cleaners, or anything rated at 1800 W or less. For my CPAP sleep apnea machine (rated at less than 50W) I can get a minimum of 3 full 8 hour sleep nights before needing to recharge. If I don't use the CPAP water feature (-20W) then I can get almost 5 nights before recharge. That's the most important feature for me. By the way, for those not familiar with energy power ratings, the "Wh" is an energy unit, it stands for "watt-hours". The 1260 Wh rating is the total amount of energy that the EcoFlow Delta can hold in the battery when fully charged. And the "W" rating is "watts" and represents energy per time, it is the time rate at which energy flows. Interesting Note:For comparison, your home electrical bill typically shows electrical energy use in 'kWh', where the 'k' represents 1000, so the 'kWh' means 1000 Wh. So the 1260 Wh rating of the EcoFlow Delta is equal to 1.26 kWh (divide by 1000 and add the k). Where I live the price of electrical energy averages about $0.25 per kWh, so the amount of electrical energy in the 1.26 kWh EcoFlow Delta costs slightly more than a quarter to fully charge. When fully charged the 1260 Wh battery can deliver 1260 W for one hour or 630 W for 2 hours or 315 W for 4 hours, etc., etc. Since my CPAP uses 50 W this means the 1260 Wh battery can provide 1260/50 = 25.2 hours, equivalent to at least 3 full 8 hour sleep nights as mentioned previously. When fully discharged it takes about 90 minutes to get it back to full charge. Also whenever you use it the display shows you how many watts are being used. And when it's charging the display shows how many watts are going into the charging process. This is good information to know to determine if you can add another device to plug in and use, or while charging if you have a generator limit (or home wall outlet limit) that you don't want to exceed. Also you can use the unit while it's charging if you need to. I recently purchased a 2021 Gulf Stream Vintage Cruiser 19ERD travel trailer and this EcoFlow Delta battery has been a lifesaver in that regard. When I need to use the coffee pot, microwave, or toaster, it's much easier to use the EcoFlow Delta battery instead of hauling out the 100 lb portable generator and starting it up to get enough power to run these appliances whenever "boondocking" without any external power hookups to the travel trailer. The coffee pot uses about 1200 W, but it runs for less than 5 minutes so it uses only a fraction of the 1260 Wh EcoFlow battery. Calculation: (5/60) x 1200 = 100 Wh. There's still plenty of energy left from the 1260 Wh total energy, in this case 1160 Wh remaining. Keep in mind these calculations are approximate since there are other underlying factors involved such as the internal DC-AC inverter efficiency rating of the EcoFlow Delta unit. Since this involves an energy loss this means any inaccuracy will show slightly more Wh than you really have. Therefore I typically derate my calculations by 5%.I've noticed that other portable power stations don't mention the 'Wh' total energy in their data specs. Instead they typically show 'Ah', which is amp-hours. So to get the 'Wh' total energy, just multiply the battery operating voltage times the 'Ah' value, and that is the 'Wh' total energy. Knowing the Wh just makes it easier to calculate how long your device will last and how much energy remains. In conclusion I really like my EcoFlow Delta portable power station, plus there are many other features that I didn't mention. If it wasn't given to me free by PGE, I would definitely consider purchasing it. It's expensive from my viewpoint, but well worth the cost. I am a happy camper!=====================UPDATE #1 9/2/21 See Below:SUMMARYJust found out some great news about another unexpected capability of my EcoFlow Delta 1260Wh portable power station. In summary I used it to power up and fully operate the 13,500 BTU air conditioner (A/C) in my RV travel trailer. The A/C unit operated at full power Max setting for 53 minutes! This short period will not cause me to use the EcoFlow Delta to run the A/C because there's simply not enough power to run it continually (instead I will use my portable generator for that). So this was merely a test to check the power capability of the EcoFlow Delta, and I am pleased with the results. More details below with attached photos. THE TESTMy RV travel trailer is a brand new 2021 Gulf Stream Vintage Cruiser 19ERD, 23 feet long from rear bumper to A-frame hitch coupler in front. The travel trailer power cable uses a standard 30A 3-prong RV connector so I added a connector adapter at the end so it could plug into the standard 15A 3-prong household connector that's on the EcoFlow Delta, see photo. Then I went into the travel trailer and turned on the A/C fan first, then the A/C compressor, then set both to maximum levels. And within a couple of minutes very cool air was being blown out of the A/C unit and into the travel trailer interior. THE RESULTSThe EcoFlow Delta was charged to 98% when I started this process and it kept going all the way down to 0% about 53 minutes later, see photos of display showing battery drain. During this time the EcoFlow Delta display showed varying power usage in the 1400W to 1500W range, which equates to current usage in the 12A range (P = I x V). The EcoFlow Delta percent remaining charge decreased over time as expected. And as the time approached 53 minutes, the A/C unit still operated at full power even at 0% remaining charge! (for about 1 minute, then the EcoFlow Delta shut down).THE REASONI was somewhat surprised, but nonetheless very glad to see this. Typically a 13,500 BTU RV A/C unit requires an extra power surge just to start up the compressor, more than what a 15A service can provide (that's what the EcoFlow Delta provides, e.g., 1800W / 120V = 15A). Yet the EcoFlow Delta did it, the A/C unit started up and operated at full Max settings. And this is because of the 3300W surge rating of the EcoFlow Delta, which was able to provide the extra temporary power surge needed to start the A/C unit. Once started, the A/C power requirement decreases to the steady state 1400-1500W range as noted above. CALCULATIONHere's the calculation to predict how long the EcoFlow Delta should theoretically run the RV A/C. It was 98% charged when I started, so that means 0.98 x 1260Wh = 1235Wh of available energy. Let's assume the RV A/C was using 1450W on average throughout the whole time it was running. (Note: it was varying up and down within 1400-1500W but let's assume an average of 1450W, which is half way in between). Then theoretically it should last about 1235Wh / 1450W = 0.85h x 60m/h = 51m = 51 minutes. That's fairly close to the 53 minutes it actually lasted during my test. So doing this type of calculation will provide a rough estimate of how long your appliance will last when using the EcoFlow Delta. CONCLUSIONFirst I will repeat my statement that I do not plan to use the EcoFlow Delta to run the RV A/C on a normal basis because there simply isn't enough power to do that on a continual basis. But this does show that I can use the EcoFlow Delta to run my RV A/C unit for short a period when I don't want to unload and start up my 100 lb 3400W external portable generator. This could be a time when we stop for lunch on the side of the road in the middle of a hot day while traveling. Yeah, I really like my EcoFlow Delta, it works great!END OF UPDATE #1 ===============================UPDATE #2 10/30/21 See Below:SUMMARYI used the EcoFlow Delta with a new corded electric 18" chainsaw, just purchased via Let's E-Bike . The chainsaw is rated at 15A which equates to Power = I x V = 15A x 120V = 1800W. Since the EcoFlow Delta is rated for 1800W continuous (plus 3300W surge) it easily provided the necessary power to run the chainsaw. I live in the Sierra Nevada mountains at 3,000 feet elevation and my 4 acre property is surrounded primarily by oak and pine trees, lots of them. In the past 2 years three trees have fallen over and two more trees have had very large branches break off, all due to high winds that come every year. So I cut them up for firewood which means lots of cuts to get them down in length to fit into my fireplace (plus I need to split them where necessary, but that's a different story with different tools).See attached photo of oak wood that I cut into sections using the corded electric chainsaw powered by the EcoFlow Delta. I started cutting at 100% full charge and when completed there was still 62% charge remaining (see photo). And since it's portable I can take it ANYWHERE on my property or anywhere else I desire. So now I've found another use for my EcoFlow Delta!END OF UPDATE #2 ==========

Only had this a Day so far, I did a Full charge of the unit and decided to run a test. The unit came with 30% on it and took about 1:15 hr. to full charge. I hooked up my 7 cubic freezer full of food with the Delta 1300, I got 25 hrs.' of total run time.8% still remaining off A/C outlet..The watts pulled when Freezer was turned on average between 80 to 87 watts. After the freezer would run for a few minutes it would turn back off and No draw came from the Delta until it came back on again. The one thing the company should of done was add a better solar cable with the unit, it came with a 14 AWG. maybe that's fine, I would of thought a 12 or 10 AWG would of been much Better choice. Hopefully if they do improvements and listen to there customer base, they will upgrade ... MoreOnly had this a Day so far, I did a Full charge of the unit and decided to run a test.

Buy this-it's awesome.

We got fed up with losing power due to hurricanes and "other" reasons in Louisiana. We finally decided to purchase something that would allow us to run our refrigerator, microwave, and a fan or two. This thing does all of that and more. It only takes about 2 hours to charge (from a standard 110 wall socket). So, we did the math. Even IF we only get 8 hours of use out of it, it only takes 2 hours to charge, food in an unopened fridge easily keeps cold for more than 2 hours without electricity. So, it's obvious that this was going to provide what we needed. It turns out that we get WAY MORE than 8 hours of use out of it before needing to recharge. We have run this thing through some rather crazy tests without realizing that we were really testing it. We've used it to ... MoreWe got fed up with losing power due to hurricanes and "other" reasons in Louisiana.

We have run this thing through some rather crazy tests without realizing that we were really testing it. We've used it to run our vacuum for vacuuming our whole house: no problem whatsoever. At one point, we had our fridge, microwave, coffee maker, TV, oscillating fan, and a couple of phones charging all at the same time on this. We had forgotten that we didn't have power in the house! The display is very useful and easy to read. There are some fans that kick in when charging, I've not heard them otherwise. I do wish it had enough to run washer and dryer or something like that-- but that's 220 volt stuff. I know Ecoflow makes a solution that powers your home though your breaker box--looks really awesome, but this unit is not for that kind of thing. Additional reason we bought this: to run full video productions from anywhere. It easily runs professional 3 camera interview shoots, with 6 lights, 2 computers, 3 monitors, 1 external RAID array, and a couple of confidence monitors. Typically, we only use about 40% of the charge in a day's use. The product does have some weight to it... it is a bunch of batteries after all. But it's easy to carry with the handles and it also fits into common collapsable rolling carts if you want to pull it behind you--which we commonly do. Overall, I'm really impressed with this item and look forward to using this thing for many, many years. I plan to try to track how well the charge holds over the years. I'll report back here with any changes in performance or break-down of the product in any way. This is a smart investment, in my opinion.

Disappointing. Almost immediately unreliable

I bought this power station along with an EcoFlow 160W solar panel. The user manual says you can use up to 400W of solar panels to charge this unit. I tested the one 160W panel in full sun when I first got the power station and solar panel and was seeing readings of 150-160W for a couple minutes, so I thought everything was working. I took it on a road trip to the desert a couple weeks later, and the power station wouldn't charge in full sun. It would get up to about 120-140W of input/charge (the number seemed to vary) and then it would drop to 0, cycle back up again to the same range of 120-140W, and then drop to 0 again. Over and over. The fan wouldn't run when it was stuck in that cycle, so I don't think it was getting any juice that way. I could only get a ... MoreI bought this power station along with an EcoFlow 160W solar panel. The user manual says you can use up to 400W of solar panels to charge this unit.

I could only get a consistent charge if I blocked some of the panels so it never got over about 90-100W. At that level, it took a couple hours to charge from 52% to 70%. Maybe the manufacturer would have been able to fix it with some effort (I saw some mention on the internet of mailing units in for firmware updates), but I returned it. It's too expensive to be unreliable right off the bat, especially when I got it specifically for off-grid use. Disappointing.

Ecoflow's Circuitry Design Is Unmatched In The Industry

There are a lot of these boxes out there and it can be hard to choose from with the tons of options. Ecoflow stands tall above the others with its circuitry design. When you are charging the unit and using the unit simultaneously, it will route the charge power to the demand before it taps into the battery storage. That is a big deal when it comes to efficiency and longevity. The only downside of Ecoflow units is that they are still using the Li-Ion battery technology. But I would rather have Ecoflows Li-Ion batteries over Bluetti's circuitry. It's not that Bluetti is bad. Ecoflows design is just that much better. P.S. stay clear of the Gucci Prepper youtube channels that want you to buy expensive short-lived portable solar panels for these.

Good bye gas generator

Our Florida neighborhood tends to loose power easily, often for hours or days at a time. We got the EcoFlow generators to power our full size refridgerator and other appliances during an outage. Initial tests show we should get 16 hours of power for the fridge per unit, plenty to last until we can recharge them. They were easy to set up and use, and our appliances worked just great. We plan to add a set of solar panels to recharge them during extended blackouts, and get rid of our gas generator.Dealing with Earth Tech was simple and hitch free, with great tech support to answer our questions and concerns. Definitely would recommend them to anyone looking to get clean, quiet, safe power.

It works as advertised

This product functions as advertised. When I received this product I ran several tests to see is it lived up to its advertised claims. For my testing I used a Kill-A-Watt meter to verify the wattage a device used and the total wattage that was used. To verify that it would run high current devices I ran a coffee maker that was rated at 1,450-watts and a 1,500-watt electric heater. Both devices ran normally. To verify that it had the capacity to run devices for the 1,260-Wh I powered the electric heater set on low (750-watts), recharged the product, and then I powered two regular 100-watt light bulbs (200-watts). I ran the heater for 1-hour and the product showed that it had 27% of the battery remaining and the Kill-A-Watt meter showed that 0.76-Kwh had been used. ... MoreThis product functions as advertised.

This indicates that the product has approximately 1,040-Wh capacity. I ran the two light bulbs for 5-hours and the product showed that it had 6% of the battery remaining and the Kill-A-Watt meter showed that 980-Kwh had been used. This indicates that the product has approximately 1,040-Wh capacity. The 1,040-Wh in use capacity indicates that the unit is about 83% efficient. While testing there was no noticeable noise while running a 200-watt device, but the noise while running the 750-watt device (or larger current) made as much noise as when charging (which is very noticeable). I have only charged and discharged it 3 times so I can not comment on how long it will last. I intend to use this product as a backup power source while camping in my camper and these values meet my needs and are near the advertised values.
