With the planned withdrawal of the UK PSTN by the end of 2025 and the ongoing switchover to VoiP many more people will come to recognise the value in adding a battery backup to their routers. Given the importance of product safety when relying upon li-ion cells, its good to see a few established UPS manufacturers offering these small domestic products. The UPS doesn't come with an AC/DC adapter its assumed that it will be connected in-line with the one already powering the router etc. The guidance indicates the UPS can deliver 3A/36W.With around 22Wh of tested usable capacity this UPS should run a typical domestic router for between 2 and 3 hours, most routers seem to use between 6-10Watts. In the event of an extended power cut the device has a simple soft On/Off button, allowing it to be shutdown and restarted as needed. There is no audible warning to indicate an input power failure, the On/Off button just has an LED which flashes to indicate the UPS is discharging its battery.The battery max recharging current is <400mA, which means the AC/DC adaptor you use has to have around 5W of headroom to safely supply the UPS and the device it normally plugs into. The documentation doesn't make this point clearly enough in my view. If in doubt about how many Watts you router is really using then it makes sense to measure it and then decide if the existing AC/DC adapter is up to the small additional load.The unit itself is a solid performer with good voltage regulation across the discharge cycle and across different load. The output voltage held steady at 11.2Volts even @3amps.One observation is that APC used to sell a much larger capacity version of a similarly styled UPS; I still use a CP12142LI and nearly 5 years on it is still protecting my gateway router from regular power cuts; sadly they stopped making it a few years back. This new mini UPS is a good solution which could have been better if they had kept some of the features in the previous model, specifically capacity, audible warning, wall mounts. The price is also on the slightly high side, but you are paying for the name and all the safety, certification that goes with it. ### ⭐⭐⭐⭐⭐ It works but for stronger hardware check the power output required & make sure this can provide it. *by on Reviewed in the United Kingdom 26 June 2025* Why did you choose this product over others?:I got this to keep my network up in the event of a powercut as we were having a large amount in our area at the time. (one for this my router and one for the cityfiber box, and a larger UPS for my PC and Server) with my router of the time (FRITZ!Box 7530 AX) being powered and working fine, Sadly for me, Ill need to change one of these out as I brought a new router (Ubiquiti Cloud Gateway Fiber) and this doesnt provide enough power output to run it. it works well, but before you buy one you might want to check the power draw required to run whatever you are buying it for if it's a little bit power hungry.recently during the heatwave, a family member unplugged the CityFiber box to plug in a fan, we only noticed it had been unplugged a few hours later when the internet suddenly stopped working, gave us a laugh when we noticed, it held up for a good bit so overall I would recommend. ## Frequently Bought Together - APC Back-UPS Connect - CP12036LI - 12V DC 36W Lithium-Ion Mini UPS, Designed for Routers, Smart Home Controllers, VoIP Devices, Networking Gear and More - APC UPS Battery Backup and Surge Protector, 600VA/330 Watts Backup Battery Power Supply, BE600M1 Back-UPS with USB Charger Port - APC UPS Battery Replacement, APCRBC124, for APC UPS Models BR1500G, BX1500M, BR1300G, SMC1000-2U, SMC1000-2UC, BR1500GI, BX1500G, SMC1000-2U, SMC1000-2UC, and select others --- ## 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.fr/products/564871114-back-ups-connect-cp12036li-12v-dc-36w-lithium-ion-mini](https://www.desertcart.fr/products/564871114-back-ups-connect-cp12036li-12v-dc-36w-lithium-ion-mini) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-24*
