## Description

Review: Works with Openreach ONT - Working ok with BT/Openreach ONT, using yellow-tipped adapter plugs (2.1/2.5mm). ONT rated 12V/0.5A (6W), well within UPC 36W max output. With UPC 27Wh, theoretical power-out time would be 4.5h. Simulating an outage fully charged, after 1hr 3/4 power left; after 2hrs, 1/2, so should be good for 4hrs. As my router (and other kit running in a different room) on an existing UPS is good for about 2hrs, this APCS UPS is perfect. Only one negative - there's no provision for wall mounting; I've just used a srrip of stick-on Velcro
Review: UPS for Openreach ONT - Purchased to replace an Eaton 3 mini powering an Openreach ONT after four years which would no longer hold any charge and kept losing power periodically. I have multiple APC UPS devices already and generally happy with the brand. It is a little more expensive than the Eaton mini but more compact and lighter. Works fine. Doesn't come with a power supply but the original power supply from Openreach can be used with one of the included adapters, the yellow ring one and then using another adapter included for the ONT itself. Tested and working immediately started charging the battery and I've tested removing power to confirm the UPS keeps the ONT powered.

## Features

- 12VDC – 36 Watts DC UPS

### ⭐⭐⭐⭐ 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.
