Mini UPS Portable Uninterruptable Power Supply Battery Backup with POE Current Transfer Function AC 100V/240V DC 5V/9V/12V 8800mAH Power Bank with LED Indicator for Webcam CCTV Camera WiFi Router

I bought 2 of these to backup my broadband and wifi routers as we are suffering with quite a few power outages. Since i have connected them they have proved their worth on several occasions and work brilliantly. I did need to buy an adapter to connect to my BT router as the plug connection is slightly larger but it went straight onto my wavlink router. Cable is very short and could do with being a bit longer but overall I think its good value for money as they keep me online and the routers connected without having to reset them all the time.

I bought this to keep an automatic cat feeder going in the event of a power cut. The feeder is plugged into the USB outlet. It works as required when I tested it keeping the clock going and operating the feeding mechanism.As the feeder has a low power requirement I think it should keeping it going for quite a while.

I have a number of TP Link hubs which need to keep running during extended power cuts. I had been using traditional mains power UPS but they had reached end of life. I got one of these to try as a cheaper alternative.Out of the box, I noticed the provided leads were very short. The mains lead was 80cm and the Y cable 30cm. Also, the mains cable had a bent pin on the UK mains plug. There was no damage to the packaging or anything so I guess it was like that when packed. Anyway, the lead was too short and I had several spare leads so it wasn't a problem for me.My TP Link hub has a 9V/1A power supply which the UPS can provide and the Y cable provided worked without adapoters being needed. Due to the short Y cable, I had to position the UPS under the TP link hub. Fortunately, they are a similar size.The UPS is silent in operation, no fans, no relays, no beeping. The hub stays up when the mains power goes off and when the mains comes back, the UPS tops the batteries back up. I haven't done a 'how long does it last' test yet, nor a check to see if it does actually power back up after an extended power cut and the batteries run out.Update: Turned the power off for 3 hours and the UPS battery level was still at 4 bars.So first thoughts are good but lose a star for the short leads.

I got this for my girlfriend to use when she goes back to Nigeria, and it has been wonderful. It has been almost a year since I got this, and it still works and retains as much charge. She uses it with a wifi router for when power goes off and it has not failed once.

Only one output plug provided and it’s a tiny bit larger than my router input plug so I can’t use it.UPDATE:I bought an adapter off eBay for £4 and the mini UPS is now in use on my sky router.I noted that the unit came with a robust moulded and fused UK plug. The fuse is 13 amp but the cable is rated at 2.5 amps (see photo). The power cable is very short forcing you to dangle the unit closer to the 240v wall outlet or use a trailing socket. I will replace the 13 amp fuse with a 5 amp for safety reasons.Pulling the power cable sees a seemless switch over to battery power so it is working perfectly as a UPS. 1 star off for the dangerous 13 amp fuse on a 2.5 amp cable and 1 star off for having to buy an adapter.

Unit working fine but the router has a 3mm plug so had to get a converter to use it.

There is only one power output which is splittable by a two way cable. this prevents the device from supplying more than one device with different voltage requirements. There is also no usb output. I have two devices, one requiring 12 volts and the other 9 volts. it is not possible to supply both. Otherwise it supplies a single device nicely, seems like good build quality.
