Taking a while to reach full charge but i like that its dc. I also like that i can have this & another ups for the rest of my equipment at the other end of the room Review: Perfect for fiber ONT - Needed to be able to keep the fiber ONT up and running in power blips because it takes forever and a day to reboot then connect. This is absolutely perfect and lasts happily for an hour without power for just that. If you need power resilience because your ONT is on a wall that's miles from any other UPS option, couldn't recommend it enough. ## Features - 12VDC – 36 Watts DC UPS - Lithium-ion battery - Comes with 3 different DC tips to ensure compatibility - Up to 4 hours of runtime - LED indicators to read UPS status and battery capacity information ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJ5D89Z9 | | Amperage | 3 | | Battery Average Life | 4 Hours | | Battery Cell Type | Lithium Ion | | Battery Charge Time | 12 Hours | | Best Sellers Rank | 9,755 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 12 in Computer Uninterruptible Power Supply Units | | Box Contents | Uninterruptible Power Supply (UPS) | | Brand Name | APC | | Colour | White | | Connector Type | DC tips (C5, C6, C7) | | Customer Reviews | 4.1 4.1 out of 5 stars (466) | | Enclosure Material | Plastic | | Form Factor | Rack | | Global Trade Identification Number | 00731304632399 | | Input Voltage | 12 Volts (DC) | | Item Dimensions | 10.9 x 9.9 x 2.5 centimetres | | Item Dimensions D x W x H | 15D x 15W x 2.5H centimetres | | Item Weight | 300 Grams | | Manufacturer | APC by Schneider Electric | | Manufacturer Part Number | CP12036LI | | Maximum Power | 36 Watts | | Model Number | CP12036LI | | Number of Outlets | 1 | | Output Current | 3 Amps | | Output Voltage | 12 Volts | | Output Wattage | 36 | | Power Plug Type | No Plug | | Product Warranty | 2 years | | Runtime | 4 hours | | Specification Met | CE | | UPC | 731304632399 | | Unit Count | 1.0 count | | Voltage | 12 Volts | | Wattage | 36 watts | ## Product Details - **Battery cell composition:** Lithium Ion - **Brand:** APC - **Colour:** White - **Product dimensions:** 15D x 15W x 2.5H centimetres - **Voltage:** 12 Volts ## Images ![APC Back-UPS Connect - CP12036LI - 12V DC 36W Lithium-Ion Mini UPS, designed for Routers, Smart Home Controllers, VoIP devices, Networking gear and more - Image 1](https://m.media-amazon.com/images/I/619Nz5b8exL.jpg) ## Questions & Answers **Q: How long do the Back-UPS Connect Lithium-ion batteries last?** A: The Lithium-Ion batteries used in Back-UPS Connect can last 8 to 10 years or 3000 charge/discharge cycles.

Taking a while to reach full charge but i like that its dc. I also like that i can have this & another ups for the rest of my equipment at the other end of the room ### ⭐⭐⭐⭐⭐ Perfect for fiber ONT *by K***P on 15 February 2026* Needed to be able to keep the fiber ONT up and running in power blips because it takes forever and a day to reboot then connect. This is absolutely perfect and lasts happily for an hour without power for just that. If you need power resilience because your ONT is on a wall that's miles from any other UPS option, couldn't recommend it enough. ### ⭐⭐⭐⭐ Almost ideal, just missing a few features *by S***E on 8 February 2024* Other than the Eaton3s mini, this Schneider APC CP12036Li is the only other widely recognised make of mini DC UPS being sold on Amazon and as such its a welcome addition to a market place full of transient clone-like products from short lived suppliers. 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. ## 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.it/products/564871114-apc-back-ups-connect-cp12036li-12v-dc-36w-lithium-ion](https://www.desertcart.it/products/564871114-apc-back-ups-connect-cp12036li-12v-dc-36w-lithium-ion) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
