It probably either connects to a PC over USB to perform safe shutdown, or it has USB output for device charging. About to look up specs.
edit: looks like it's for PC communication. Discovered they don't post to regional Vic. Bugger.
Comes with software that you install so the UPS can safety shutdown your computer.
USB is just to communicate when there is mains power outage. It sends the signal to the PC or NAS etc to initiate safe shutdown.
Is the battery replaceable? Can't find the info on spec
Yep, these have user replaceable battery but strange this 850 don't list in their spec but in descriptions.
Thank you
2 of these over a single 1500VA model ? https://www.ebay.com.au/itm/334009873800?hash=item4dc48a3588…
Basically thinking one for the PC - safe shutdown, and one to keep the broadband and wifi running in a power outage?
aren't the main NBN 'boxes/hubs' outside on the street also powered by mains? they certainly don't have their own generators and aren't big enough to have a large battery reserve if they have their own UPS. point being - if there is an area wide power outage the area's NBN may also be down so having your router and NBN endpoint on UPS might do nothing (and it'd only be a hour or two's worth of power at most with an 850VA UPS).
Vulnerable to power failure is yet another feature of our nbn network implementation.
oh yeah.. a ridiculous step backwards.

Depends on the connection technology.
FTTC (which is what I have) is powered by the NBN modem in any connected houses, which is in turn powered those customer/s power points.
Unless your NBN router has a 4G backup. You'd still get some connectivity if you had a UPS.
Mine is wireless nbn and I also have ADSL (load balanced). I believe both should function if the modem is powered on.
FTTP works during a blackout and I have a UPS for just this purpose.
Everything else doesn't.

I got put off these Eaton 5Es when I tested the 650VA model with an incandescent light bulb and it flickered. Pretty rough output, haven't seen that on any other modified sine wave UPS I've tried.
Is there a USB port or not? The linkes Specs page shows back of the unit without USB …
Looks like it is on the front
Out of curiosity, what do you use this USB UPS for?
