Anyone here suggest a decent UPS to power modem/router and perhaps give me 5 mins in time to power down the home server. Get a few drop outs a year and probably 2 x 1 hour cuts a year on average. Very annoying. Is it worth getting a UPS for these. Don't mind spending from 70 to 120 quid if it's going to be worth it. Thanks
 
Be warned the smallest ones will typically only give you 1 minute at full load or 9 minutes at half load.
 
I use an APC Back-UPS Pro 900. Does the trick for me. Gives me around 20mins runtime for my Server, Modem & Switch.
 
Sky Q and router on an APC Back-UPS 700 here because I record a lot overnight when our countrified electricity gets a bit iffy.
Andi.
 
I've got a "APC Back-UPS ES 700" - Paid £75.

Powers my server, modem, router, switch, and wireless AP for about 10/15 minutes.

The APC stuff (as well as others I'd imagine) also get plugged into your computer via USB and combined with their software will automatically power down your computer when you get to 5 minutes of battery left (or other user defined options).
 
One problem with many of the lower end UPSs is the recharge time.

The recharge time on the APC Back-UPS ES 700 is 16 hours. The recharge time for a similar capacity Smart-UPS is 3 hours.
 
The APC Back-ups models like the 700 are fairly decent but I've found they don't take rough handling in transit well - between my personal use and business I've had reason to order maybe a couple of dozen from varied vendors of which around a third had to be replaced 2-3 times out the box due to issues with the battery and they all come with a printed out engineers checklist/certification of working which I doubt has been faked as APC have a fairly good reputation which leaves me to believe they've been thrown about a bit in transit and not taken it well.
 
Personally I buy APC units without batteries cheaply and then buy new batteries. I have a collection of APC Smart UPS' from 700 to 1500's to run my local server and workstations, the 1500 keeps the PoE switch (voip phones), router and server going for a good while, ages if the server shuts down. Just use one of the IEC break out strips and it'll handle normal devices easily.

Any suggestions just to use on modem and router only ?

bledd linked something that might be good for that above - alternatively if the devices are 12v if you can find a power bank that does 12v output and can charge/pass through at the same time as supplying an output that is potentially another idea - unfortunately the Anker 20,000mah jobbies I've been using for that seem to have been discontinued.
 
A lot of the WISP gear is designed to power 12v/24v kit so might be a better option than having a UPS convert from the internal batteries up to 240v, for a power supply on the kit to drop it back down to 12v.
 
A Ups may be better because the current location of my server from my modem and router is close enough so I could use the ups and have it shut the server down correctly and just keep the modem/router live till power resumes.
 
You need to get some actual numbers, firstly measure the power usage of each item you want to use, calculate how long you want it to run for and then purchase a suitable UPS. Big difference between a low power atom/i3 running SSD's with near zero load and a 20 drive i7 running flat out trans-coding to a load of remote clients.
