I'm considering getting a UPS for my den and at first glance << THIS ONE >> appears to be good, but I'd like to get some advice and opinions from people who have one.

 

Ultimately I'd like to get one that gives me at least 2 hours of continuous use after an outage. 

 

The items I would have plugged in are:

 

WiFi router, laptop, 20" LCD monitor, telephone and a LaserJet (not printing).  I figure I can do without the TI during an outage.

 

I'm considering a second unit as well for the living room powering  a 42" LED TV and a satellite receiver and possibly even a lamp with a 12 watt LED bulb.

 

Comments, advice, suggestions?

I highly recommend the APC Smart UPS units, similar to linked: https://www.amazon.c...c smart ups 750

 

I have used APC UPS units for about 11 years at both home and where I work (supporting ~150 computers locally daily); we have really dirty power here and so far I have not had more than a handful of machines die on me.

 

The batteries tend to last 3-5 years.

 

(edit to add that we also use the rack-mount ones to support all our network equipment nationwide as well, but that might be overkill ;) )

Have you measured the power draw of all these devices?

I would NOT support the LaserJet printer on the UPS! Even at idle, the fuser is kept warm, wasting precious watts.

 Nope, I don't have a KILL-A-WATT, but I can always get down on the floor tomorrow and and read the ratings of the power transformers.

Good point!  I should get in the habit of turning it off when not in use.  I've been keeping it on standby 24/7 in case I want to print anything or receive an email over it.

APC ist best, but no laserjets on a UPS

2 hours maybe is a joke. I give you less than 30 minutes (with 1500VA).

but depends on your TV´s wattage, and maybe maybe, but I don´t think so

I post a photo of my USVs later, to show how you can gain 2 hours ;)

great point made (that i forgot) about the laserjets- the power draw will freak out a UPS if you have it plugged into 'battery' side.  have to plug in to 'surge' side. :)

Well technically I could plug the laptop into the surge side and run off it's internal battery for a couple of hours, that would just leave the 20" monitor and the router plugged in.  If I cant get at least 2 hours out of those two devices, I'll just forget the whole idea as I'm not willing to spend over $200.00 on this.

IIRC there is a power calculator on the APC website.

If the TV doesn´t suck so much, maybe it can work. Just check the powersupplies

 

Or maybe someone here can calculate that ?
