TalentCell Mini UPS Uninterrupted Power Supply 27000mAh 97.2Wh Lithium ion Backup Battery Pack with DC 12V/9V and USB-A/USB-C 18W Output for Router, Modem, LED Light, CCTV Camera, Smartphone and more

Where we live we often get power cuts and as we are now working from home it can be a pain so I looked for a device to be able to keep working.I originally wanted something to power the computers and router but found they were very expensive so I decided on this unit to provide power for the router and mobile phones to keep working.It has outlets for 4 x 12v supplies, 1 x 9v and two USB outlets to charge mobiles etc. It also comes with some cables - you can buy different sizes as the ones that come with it are 5.5mm standard connectors. NOTE if you have a BT home hub they use their own strange size - 6.2mm I think so I had to make up a lead to fit.So last week we had another power cut and with the laptops charged up I plugged in the device and connected the router and mobiles (if you have fibre broadband the wall box should have a battery in it to keep it going).I also plugged in the telephone which uses a 12v power brick and everything worked perfectly for the whole afternoon the power was off - this was around 4 hours and even then the device showed a pretty full charge so I suspect the laptops would have lost power before this did.Not had the device for long and only used it once so can't comment of how it will last but so far very impressed. It could be improved by a better selection of connector cables but as I said these can be bought easily on Amazon.Very impressed and recommended to keep you going in a power cut!

I bought this to power a Vigor 2865 router because of the risk of vandals opening the external meter box and turning power off.It does this reliably - and when we had a local power failure kept the internet alive for over 10 hours.I do worry about the safety of keeping a lithium battery on charge 24/7, but it does not seem to get warm at all. I would have given it 5 stars if it had some certification to re-assure about fire-safety etc.

I've had this for10 months now. It's proved itself three or four times during short outages, and also during a longer one of about 90 minutes. I haven't measured how long it would last, but it was still at over 50% according to its LEDs after the 90 minute outage.It runs 24x7 the following...From USB outlets:o Hue bridgeo Yealink VoIP base stationFrom 12V outlets:o Draytek Vigor 2865ac Router (for 1Gig fiber with ADSL failover, DHCP, VPN remote access, Wake-on-Lan etc)o Beelink EQ12 N100 (Windows 11 with Home Assistant in a VM & 8TB SSD NAS)o Mokerlink 8x2.5G + 1x10G switcho Deco AX75 WiFi 6E MeshI was careful to limit the power draw, particularly by dropping power requirement on the Beelink, but I also wanted 2.5Gbps+ LAN which is a headache when power consumption is a limitation.As such, the whole lot idles along at 24W from the wall. This is getting a bit tight for the supplied 12.6V/2A wall wart, so I upgraded it to a 12V/3A unit I had.So unlike my neighbours, when I have a power outage I can still enjoy internet, WiFi, and VoIP phone, even if it is in the dark!

The device is only supplied with 5.5x2.1mm cables, when most 9v and 12v equipment I’ve ever found requires 5.5x2.5mm, meaning you have to buy some adapters and additional cables (because who has 5.5mm male to male cables lying around?)For the price, I don’t think it would have hurt to supply a couple of 2.5mm cables, and the cables that are supplied are all very short.It’s little disappointing when a £70 device arrives and you can’t use it immediately for the lack of a 50p cable that it should probably be supplied with.Edit: I later returned the device, it wouldn't charge properly and my router attached to it would switch off periodically. Maybe I got a duff unit, but certainly it didn't work for me

This is my 3rd UPS unit, my first 2 are running my 7 cctv cameras and dvr, i'm using a higher power charger to charge both at once, they are doing a great jobI recently bought this one that powers my router, a usb desklamp, and my tablet (had some minor power failures here)For the first 2 i was disappointed that the 9v output was the same black connector, unlike the 8300mah version, contacted support and they sent me the connectors that i changed myseelf, note that the 9v is a different size.and yes, i have the 8300 and the 3000 as portable packs, all have been reviewed on my YT channel.

These only last about a year and then are useless. I had a power cut the other day, and one of the three I have just switched off with the power. Absolutely useless.
