That's the rabbit hole I'm tumbling down into as well haha. Short answer: Yes(?)

Long answer: Yes, but. A quick Googling brought up this EcoFlow article: https://www.ecoflow.com/us/blog/u...wer-supply although they seem to push people more towards a newer product called the RIVER 3 Plus. It seems generally that faster=better when it comes to switchover time, so anything 10ms or less should be fine.

The product page itself has the following bullet point under Specifications:

"When the power goes out, DELTA 3 Classic reacts instantly. With a 10msautomatic switch-over, it keeps sensitive devices-like NAS systems, CPAP machines, and servers-running without interruption. No data loss. No downtime. Just peace of mind."


For comparison, I was likely going with a UniFi UPS 2U (drinking that Ubiquiti kool-aid after getting a UDR 7) and they advertise "Transfer Time: 6 ms typical; 10 ms max. (Battery mode)" on the UniFi product page. Far from an expert so please double check my take before making a final purchase. I've been wanting to add a UPS for my little 15U rack and going in circles of "what's my best option?". I guess if you're not happy with it then at least you can rely on Sam's Club return policy to get your money back.

Edit: @bluskye brings up a great point that I missed regarding connecting your device(s) via USB as well.

Im in the same situation with my UNAS PRO. Its annoying it can only be shutdown from a Unifi UPS vs standard NUT server on the network, like super annoying. Shutdown on devices with HD's is important.

True, but realistically for a 1kWh unit like this, you will have plenty of time to manually shut down your NAS or network devices if needed, compared to the River 3 Plus at 1/4 capacity.

One glitch I wish it's better is probably operating efficiency, this Delta 3 Classic is going to be less efficient to run 24x7 compared to smaller River 3 unit simply due to this having a much larger inverter that peaks 1800W. I have this unit and with it plugged in, even with passthrough charging which shouldn't run the inverter, I'm still seeing a constant 10-12W additional draw on top of the load used by stuff I plug in. Not a lot but just annoying, because my friend got a River 2 Pro refurbished and that thing only takes additional 3-5W to run, both plugged to the wall. Might be a bug in Delta 3's firmware, hopefully it gets fixed.

But problem with this deal is $380 is a bit high, I got mine during black Friday for $250 before cash back and tax.

I have a much smaller NAS with just 2 HDD and full flash storage so most of the time power draw is very low with HDD all put to sleep. With a 1 kWh unit like this, you should have plenty of time to initiate a shutdown manually. Yes having a real UPS with USB auto shutdown is nice but if you can get this Delta 3 for actually good deal like during black Friday, I wouldn't mind about not having USB.

For my system which draws just 40W with HDDs in sleep including a WiFi router, it'll run for nearly 20 hours before draining the battery completely.

Oh and one thing to note, not sure if Ecoflow fixed their app for River 3 Plus or not, but they don't give low power notifications for many of their River series, including my friend's River 2 Pro. While the Delta series all receive real time app notification when it switches to battery power and when it dips to 20% battery.

Yeah, I know these units have plenty of power, but I have a full rack of unifi gear, I hesitant to go back to a UPS box that sits off the rack, its not tidy. I may just get another cyberpower rack unit. Im convinced Ecoflow will start releasing rack products in the future, it only makes sense to crush legacy lead acid battery products.
