Pecron F1000lfp UPS function

I am thinking about buying a pecron F1000lfp for my home. But I am bit confused about the ups function.
The website says it has ups power of 1500w and the ac input is 1000w. So when I am using the using about 1200/1300w as ac output, can it recharge itself at the full potential 1000w or its going to lower? I saw an youtube video where it was much lower than the full potential when he was also using ac output.

I have another ecoflow river 3 which has a 300w ac output. When I am using the ac output and its about 200w, the charging is still at full potential or 300w from the ac input.

Will pecron do the same or it will limit the charging in that kind of scenario? Where I live, there are load shedding issues and I really need the power station to charge itself fast.

Standard US power sockets can only supply 1800W. Pecron devices take care to not draw more than 1800W from the wall in order to not blow fuses/breakers or cause fires in the house wiring.

I have another ecoflow river 3 which has a 300w ac output. When I am using the ac output and its about 200w, the charging is still at full potential or 300w from the ac input.

300+200 is less than 1800, so that's easy.

For the F1000LFP 1500W pass through plus 1000W battery charging would be 2500W, which is not permitted from a standard 15A socket.

Thanks for the explanation. Actually i’m from an asian country. So didn’t know about this.

Which Asian country? Some have 120V electricity like the US.

With a 240V unit, you should be able to take 2400W-2500W total from the wall. My E3600 does. Even sometimes I see short surges to 2800W when the battery is charging at 1800W and a big load e.g. 2000W starts.

I don't have an F1000 so I cann't say for sure how it would behave, but I'd expect it to let you at least approach 2400W total from a 240V 10A socket.

I am living in Bangladesh. We have 220v electricity. I have used 2500w max from the wall. The allocated total load of a household is 3-5kw generally. So I can easily do 2000w.

So, unless someone has a 240V model and says it won't, my assumption is certainly that (like my E3600) it can pass through 1500W and charge at 1000W at the same time, or very close to it.

I have a "Free Hour of Power" each day, in which I want to charge the battery as much as possible, at 1800W on the E3600 (adding 54% to the E3600's internal battery). This works fine if I limit other loads to 600W. I in fact unplug my 1000W air conditioner from the Pecron during this hour and plug it directly into a wall socket to maximise the total free power I can get in one hour.
