Because it connects via USB, the NAS is notified of a power outage and shuts down gracefully after a pre-determined time. I've also connected a Virgin Media modem, a router and a USB hub and, based on my trials, they'd all run (including the NAS) for about 40 minutes, which is more than I'd expected. That said, I've got my NAS set-up to power down gracefully after 15 minutes - which should see me through any quick drops in power or outages. I figured if the power's still out after 15 minutes then it's probably going to be a long outage which would exceed the UPS's battery capacity anyway. Nice to see the UPS also has battery drain protection built-in, meaning it would power off before fully draining (which would damage the battery). So yeah, I highly recommend this UPS. It does exactly what it's supposed to do and does it very well. Review: Back up power for a BT modem? This seems to do the trick. - I live in an area subject to irregular, but relatively frequent, power cuts. Four in the last month, each for a variety of reasons, and each lasting a couple of hours or so. The usual apologies from the supplier (Northern Powergrid) but no confidence matters will improve anytime soon. When they're blaming squirrels you know you're in trouble... Unfortunately, the mobile networks go down too, so our entire village goes off the comms grid. With BT digital voice allegedly coming next year we will be deprived even the trusty landline. So some kind of contingency makes sense, if only for emergencies. There are any number of these units on desertcart, and you have to pick one, so the Eaton 3S mini was it. Arrived in a couple of days. Easy to set up. Although it has 4 dc power outputs the default setting is 12V, fine for the BT hub we have. There are 4 barrel connectors included, one being 3.00mm which is compatible with the modem. It fits, and that's good enough for me. Took about 10 mins max to install, let it charge overnight, then switched off the mains power to the hub this morning. The latter continued to function. So far so good. We'll have to wait for another power cut to test in in real world conditions, but assuming the back up batteries in the BT street boxes are good for a couple of hours then we should be ok. We'll see. Update 4 July 2024 Another power cut this afternoon. 6 now in 7 weeks. Step forward Northern Powergrid... We were reconnected to the mains supply after 1 hour 45 mins or so. The backup battery kept us connected but judging by the status lights on the front I guess we had another 15 mins tops. So 2 hours powering a standard BT modem ## Features - Mini UPS to secure power continuity for connected equipment during power outages.

The 3S Mini comes with a 2 year manufacturer warranty. **Q: Does it really have a power factor of just 0.4?** A: No all this means is it will provide 9 minutes of full power for 550 Watts of items, should domestic power fail. So if for example if you were powering a 150watt pc ,you would have enough power for 27 minutes while the domestic power is off **Q: Anyone connects their ups via an extension lead? which extension lead would you recommend me buying for this? thanks.** A: A surge protected BS1363 extension of an appropriate length to suit your needs. Master plug make some reasonable ones **Q: My orbi rbr50 router is 12v 3.5a will this provide enough power to run it? description says 12v 3a, so should i assume no?** A: Thank you for the question. This UPS would not be sufficient to power your router. I would recommend taking a look at our 3S 550B UPS as a potential alternative https://www.amazon.co.uk//Eaton-550B-UPS-Uninterruptible-Interface-Black-white/dp/B0B3RS2986 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly *by A***S on 20 April 2026* I bought one to keep my Synology NAS running in the event of a power outage.

So 2 hours powering a standard BT modem ### ⭐ Batteries failed prematurely - may have no minimum voltage cut-off *by A***A on 9 July 2023* I own three of these units. Two worked great during a power cut yesterday, but one of them instantly dropped the output power. They are all around 12 months old. The one unit which failed had actually been fully discharged once, several months ago during a previous power cut. The other two units did not fully discharge, because they have very light loads (~3 watts vs the ~9 watts attached to the failed unit). Both of the lipo cells inside (TP LI-ION 3.7V ICR18650 2200mAh MH46259 UD020) now read at roughly 0.125 volts, so my /assumption/ is that these are unprotected cells and the unit itself does not have a low-voltage automatic cutoff. This is extremely problematic, because whenever there's a lengthy power cut, there is a solid risk that the unit itself will then be bricked unless you want to manually replace the lipo cells inside. So I'm afraid I need to give the "overall rating" as just one star because of this. Sorry, Eaton. Unless I'm mistaken and the one unit is faulty, then you will need to release a revision 2.0 which includes proper cell protection. Ideally they would auto power-off at, say, 20% power remaining. Perhaps even make the percentage/voltage configurable with a DIP switch somewhere, but obviously a DIP switch would add slightly to the materials cost & the plastics would need redesigning, so a straightforward X% cut-off would be the most reasonable thing to implement. ## Frequently Bought Together - Eaton 3S Mini UPS 36W 9/12/15/19 DC to protect Internet routers, IP cameras, home assistants and smart controllers - APC Back-UPS Connect - CP12036LI - 12V DC 36W Lithium-Ion Mini UPS, designed for Routers, Smart Home Controllers, VoIP devices, Networking gear and more --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/372818820-serie-3s-mini-dc-ups-3sm36b-36w-backup-power-routers](https://www.desertcart.tn/products/372818820-serie-3s-mini-dc-ups-3sm36b-36w-backup-power-routers) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
