if you folks want to know how long these things will last, you simply need to apply some simple math. volts x amps = wattage. this thing has a 1 kwh battery, so not accounting for efficiency losses, around 1,000 watts for 1 hour.

all you have to do is calculate or estimate the hourly wattage of your appliance or particular draw. if your device averages 100 watts used per hour, it will last less than 10 hours, because of some efficiency losses incurred during the inverting from dc to ac.

if your device uses 1,000 watts, it will last less than an hour. 500 watts, less than 2 hours. 333 watts, less than 3 hours. 250 watts per hour, this power station will last less than 4 hours.

there is also the issue of self-consumption or idle drain. loads that are not very high, but need to be powered for a long duration are going to require the inverter to be on the whole time, so, you will lose even more.

a microwave at 2000 watts will run around a half hour, give or take with this power station. idle consumption doesn't come into play, because it is a high draw load for a short amount of time.

leaving the inverter on constantly to power a fridge for several straight hours, will consume a bit extra because of the extended period of time wasting from self-consumption.

simply figure out what your particular load draws hourly, and divide by, say 900 watts. the battery is rated at 1024 watt hours, but after accounting for inverter losses, you might get around 900 watt hours, give or take, out of the power station.

so, you can power a device that draws a constant 900 watts for 1 hour, or a device that draws 100 watts for nearly 9 hours. a bit less than 9 hours, because the inverter being on for 9 hours straight will self-consume more watts than if the power station was on for only 1 hour.

listen, clown. i did address fridges in an earlier post in the thread. i am fully aware that fridges and sump pumps are intermittent, which is why i explained the math concept to him, so after determining how much his loads draw on average, he can figure it out for himself instead of having to ask others, who have no idea what sort of average draw his fridge or sump pump uses.

he and others obviously would be benefited by spending $10 or $20 on an electricity usage monitor (e.g. kill-a-watt meter), plugging it into their fridge or sump pump to figure out how much it uses on average hourly or daily. then simply take 850-900 wh (accounting for efficiency losses, you won't get the full 1024 wh rating on the delta 3 plus) divided it by your avg. load, and you will get how long it will run.

the problem was not my explanation, the problem is i have no clue how much his sump pump typically draws over the span of a day, so i simply cannot provide him a satisfactory answer without more data. i have no idea what folks' fridges draw either. there is a wide variety of fridges out there, and some may use 1.2 kwh hour per day, and some might use twice that amount. there are also variables such as whether the temperature is a constant 72 degrees or is it 95 degrees in the house in the middle of august, because folks have no ac to maintain a constant temp in the house. (not everyone has ac and has a consistent temp where their fridge is located).

so, pjpe down. if you don't have anything useful to add to the discussion, mind your own business.

depends on various factors, including how big of a fridge and what kind of energy it requires, ambient temperature, etc., but at least 10 hours or more for larger fridges, perhaps a few hours more for a smaller or more efficient fridge. less than a day for sure. i would say around 10-12 hours on average.

Thanks OP, been waiting for a deal on this new product from EcoFlow -- Delta Plus 3. Yes, it's only 1kwh so I'll need to be looking for deals on extra batteries to reach 3kwh (Delta 2 battery series, Delta 3 battery series or even cheap generic LiPo4 battery). This is almost the same as the $500 eBay refurbished Delta Plus 3 deal from EcoFlow.

To state the obvious, your math does not account for intermittent power draw.

Ya' know, like a fridge or a sump pump.

And a 2000 watt microwave, would be a rare beast indeed.

For such a lengthy lecture, you didn't actually have anything accurate or useful to contribute.

I researched this a bit because I need a UPS replacement and it's apparently not a very good one 😞
Hopefully ecoflow will figure this out in version 4...

I was thinking of doing this, but it seems like it's pretty good for home network stuff like switches and routers. My issue with APC is that they don't seem to have the best longevity unless you pay for the expensive ones that are much more than this D3P.

Delta 3 1500 refurb is now $450+tax via ebay with the special 10% extra coupon

50% more battery
15ms vs 10ms switchover but tests show 10ms only happens when 3plus is actively charging

(and you don't need more solar input than 500watts on this level unit)

Get a Kill-A-Watt power monitor and plug fridge in. Check back after a few hours or 1 day and see how much kwh it draws. Keep in mind more door opening=more power draw

I have the Delta 2 and I absolutely love it. I bring it camping with me every time. I've done a set up at camp where we had a whole ass DJ set, all powered by delta 2 for basically half the day. I'm definitely interested in buying the newer version.
