The voltage selector allows complete flexibility if you want to use it with different devices, awesome. Review: Battery deteriorated rapidly, and no support from Eaton - This looked promising to provide backup power to an internet router - small size, felt solid, and worked as expected first time out the box. Thing about a UPS - you only know it's failed when you need it. Fast forward a year and when we had electrical work done, mains was turned off and internet died. Same shortly afterwards when we had a tiny power blip. Pressing the button to check the internal battery charge showed it was at less than 5%. So at some point in past year the battery's completely deteriorated. Rang Eaton support line twice. Went to voicemail both times - "all our agents are busy", which is fair enough but no one's rung me back. When reporting to desertcart they experienced the same thing! desertcart sorted a return and refund, of course, but nothing positive to say about Eaton. ## 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 ### ⭐⭐⭐⭐⭐ Great device *by A***R on 18 June 2026* Brilliant little UPS, Been using two for a while now and they have kept my devices running very smoothly during power breaks a few times now.

Very well made and good liking for what it is. Missing screw holes for wall mounting and the multi-adapter power connector can drop out of modem if it’s wall mounted vertically as it’s too fiddly (have had to tape the power connector into modem to keep it secure). But totally worth it and recommend despite niggles. The battery works great and powered modem for over an hour in testing. ## 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.ro/products/372818820-eaton-3s-mini-dc-ups-36-w-3sm36b-dc-outputs](https://www.desertcart.ro/products/372818820-eaton-3s-mini-dc-ups-36-w-3sm36b-dc-outputs) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-20*
