Deal Details
This is a Charger + Inverter + ATS (Automatic Transfer Switch).
This combination will cost a lot lot more if assembled from separate components.


Transfer speed in ms might not work perfectly with all network/computer components, so for the most reliable UPS you might have to add a regular UPS in front to be safe.
Edit: The Technical Specs say transfer speed/switch time is <5ms so that should be plenty fast for a UPS.

This is pretty big and heavy duty (which could be a good thing), so make sure you check the dimensions and account for it in your location.

Combine with the very popular high capacity LiFePO4 battery deals to make an auto-switching battery backup system.

yes, do note: "Transfer speed in ms might not work perfectly with all network/computer components, so for the most reliable UPS you might have to add a regular UPS in front to be safe."

Switching time sensitivity seems to vary a good bit between different electronics components. Of the devices I have I found computers to be less sensitive, and network equipment like switches and cablemodem to be more sensitive. Probably depending on any capacitors inline or not..

Almost all the transfer mechanisms except real UPSes are likely a roll of the dice, if you really want to test and see.. People are likely to be disappointed or caught by surprise if they use any of these, including all the power stations, "EPS"es, Ecoflows and what not.
I see "real" UPSes have switchover delay of 8ms or so.. And the "green" ones also are made to consume minimal (2-5W) power when "idle" or floating.

So if one wants to be sure, get a cheap UPS ($40ish) and stick it as the first defense. You'll free yourself up to have any big backup after that, and can even manually switch on/off while the first UPS drains..

But if your use-case doesn't mind a quick reboot (most people likely don't have very involved setups that can tolerate 0 resets), just put something like this and call it a day.


EDIT: Technical spec sheet says transfer speed < 5ms . If that's accurate it should be plenty fast for a UPS function.

So this might be good if you were going out camping and wanted a battery system you could plug a lot of power-demanding things into but not necessarily good for computer systems you want to be safe at home? I'm looking for a UPS system for my computers and I don't know if this is something I should even be considering over a traditional UPS.

You should want *really badly* to have a long backup for your systems, to invest the energy into something like this. If you just buy a traditional UPS you will get 20-30 min of backup with appropriate sizing, and call it a day.
If you want for camping etc. you should get a "portable power station". There are ecoflow and other brand ones posted regularly.

Some very, very negative reviews, and not a small number of them.

The only one that bothered me from looking at all the reviews and Youtube was one guy who saw a capacitor leak. That could be a problem if widely experienced and not a one-off.

Otherwise, this seems to be a steal, being big, heavy and beefy, transformer design etc.. And the only other issue seems to be ground/neutral swapped on some early revisions{?) . That's easily testable and changed if still an issue.

Which aspects of the reviews bother you the most..? would be good to get your thinking..

The part i don't like is when they say their system failed and the manufacturer won't respond.

well, lots of these things just work, else return to Amazon, else write off to luck.. you come out way ahead in the long run.

But if there is a safety issue or the house catching fire I tread very carefully.. You definitely don't want your house to catch fire in the long run!

That's a pretty low bar.

Strange perspective.. Safety being the only non-negotiable criteria is "low bar" ??

Well, price went up to $170 or $225 it looks like.. so if it wasn't a good deal for someone at $140, it's good to look at alternatives even harder with.a higher price..

I'd been watching the 1200W version and missed this one on sale...and now 1200W is completely removed from the amz page
