Review: Plug and Play - As advertised: Supports a recent-model Openreach ONT no problem, ran for over an hour and went about 30% discharged (ish). Installation quick, plug-and-play, with the supplied yellow tip adapters. Cable on the unit, though not shown in the pictures, is plenty long enough!
Review: Excellent product but may need additional connector ends/tips. - Excellent product for router - gives good emergency cover for power-cuts or spikes. Looks smart and is quite discrete. One star off for limited (two) conversion tips for plugging the UPS into the router - these did not work with a BT Hub. Not a major problem: I had to buy a cheap set of a dozen different converter ends to get one that fitted. But it might encourage a user to try and force a connection or hack on which could damage the modem/ router.

### ⭐⭐⭐⭐⭐ Plug and Play

### ⭐⭐⭐⭐ Excellent product but may need additional connector ends/tips.
*by C***N on 10 June 2026*

Excellent product for router - gives good emergency cover for power-cuts or spikes. Looks smart and is quite discrete. One star off for limited (two) conversion tips for plugging the UPS into the router - these did not work with a BT Hub. Not a major problem: I had to buy a cheap set of a dozen different converter ends to get one that fitted. But it might encourage a user to try and force a connection or hack on which could damage the modem/ router.

### ⭐⭐⭐⭐⭐ It works but for stronger hardware check the power output required & make sure this can provide it.
*by K***. on 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.
