Not an ATL, but a decent deal.
Have one and it does the job for the NAS + router, doesn't last long at all but enough for NAS to auto shutdown and router to stay on for 30 or so minutes.
CamelCamelCamel.

So you can have an uninterruptible uninterruptible power supply.
Home batteries often have close to a 1 second switchover.
These are for computer use where losing power even for 1 second can be harmful.
Are they for computer use? … I can't find anything stating they are pure sine wave, my PC won't run off my modified sine wave inverter.
Thats not a good sign, id be prepping for a new PSU.
PFC enabled ones tend to be picky about modified sine but not instantly, typically takes a few minutes to heat, much longer than a clean shutdown takes.
Even my $5'000 enterprise UPS in my datacentre is modified sine; you only need pure sine for things that run directly from AC, like pedastal fans, microwaves, anything with a compressor. Etc.
@MasterScythe: It is a new PSU … & a mid range good quality one, Small switching supplies cope with a modified wave … never known a single ATX that can handle anything but pure!
@Series4Episode10: Return it then, thats faulty.
And whatever brand can't run on a standard UPS, name and shame them.
My home servers, gaming PC, 2 racks worth of equipment in my workplace datacentre, and every workplace over my 30 year IT career has no issues, nor should they have.
Something is wrong with that PSU.
People who don’t want giant explosive batteries in their house that take decades to cancel out the initial expense. Plus the EFM if you’re concerned about that stuff.
I’d like to eventually have batteries, but they’re sure as hell not going in my garage.
The ones I've seen sit outdoors.
I specifically chose to have it in my garage. Out of the weather, but nowhere near the house.
That's a joke right? Right?
Is this pure sine wave?
Yes it's pure sine wave and a billion gigawatts for $79
Not at this price. Simulated.
whats the benefits for pure sine wave? is it overkill for household use eg NAS, modem, router etc?
Pure sine wave is needed for things that run off AC, like compressors or fans.
Most things we want this for run off DC, so as long as the adaptor sees an AC signal, itll keep working. Usually the power pack will be a little warmer, but modified is very common and safe, its square you avoid.
Does anyone have experience with DC UPS for devices that use DC? It'll bypass the step down transformer/adaptor and be slightly more efficient?
Yeah ive made a few.
I just use a maintence charger hooked to a 12v LiFePo4, and a Pololu 12V Step-Up/Step-Down Voltage Regulator for output.
Ive switched most of my batteries to LiFePo4 now, i like the non-flammable aspect.
Noticed this UPS without USB ports for about $100 delivered if you have eBay Plus.

This however will require you to manually shutdown your NAS but should give you a lot more runtime for those short blackouts.
If you really wanted I assume you could write a polling script linked to a cronjob to shutdown your NAS if you loss connection to say the internet or firewall for x minutes.
I assume AI such as copilot or another free AI service possibly could write + step you through the entire process.
Good idea, however for these things it's great to KISS
Yep. I just ping my router which isnt on the UPS.
No reply for 1 minute, shutdown. Always KISS.
Thanks. Bought one for my CCTV in case crooks decide to turn mains power off to house so I can catch a few more mins of footage.
Lock the Meterbox.
I thought you had to leave them unlocked for meter readers though? Happy to be corrected.
You still don't have a smart meter?
in the market for UPS for my NAS (synology DS920+) mainly esp planning to add ssd nvme 2x for read/write cache.
is there real benefits of choosing pure sine wave UPS and replaceable battery?
something like https://www.amazon.com.au/CyberPower-Sinewave-900VA-540W-Tow…
overkill or the product in this deal is sufficient?
Been running my 2 NAS units (different physical locations) for years. They email me when power is lost and tell me how many minutes are left. I configure the NASs to turn off when the battery tells them it is low.
Never found a need for pure sine wave.
I do consider them to be consumables though - as long as I get 3-5 years out of them. Replacing the battery (even if possible) would probably not save much over a whole new unit. Currently using this one:
https://www.amazon.com.au/CyberPower-VP700ELCD-Value-700VA-3…
which gives a decent run time, a nice display and USB ports.
The one you posted is a fine choice though a bit expensive to replace every few years.
thanks mate. i think i'll be going with what you are using as well since sounds like pure sine wave isnt needed for my use case and still have USB HID port to connect to my NAS.
the one that i looked at before while its battery is replaceable, i could not find a shop in AU which sells it, so no point getting that for its battery replaceability..
Nice unit, almost got it. My APC BX950MI died, was lucky to find replacement battery for $40 at Jaycar. The old battery had cracks on one side!
https://www.jaycar.com.au/12v-9ah-sla-battery/p/SB2487
Officially BX950MI battery is not replaceable, but once you open it (tricky), it is easy.
This model doesn't have a USB port. The 850 has a usb for the auto-shutdown

man I haven't seen those things from the 90s !
What things?
This isn't a deal for Reebok pumps.
Btw this is only 1 dollar more because that deal used a targeted code so you can do the same with other $10 off deals happening atm
