Most accurate way to determine wattage pulled for a UPS

@Eigenvektor @Ryan_Vickers - I will be unplugged, with desire to be unplugged and mobile for at LEAST 1 hour at idle with 10-20 times at max print burst (2 pages) and CPU usage, though my CPU calculations may be a little more frequent.

Mobile could be a bit of a problem. A UPS isn't exactly known for being light weight. I think the unit recommended above is around 25 kg. You don't plan on carrying that around with you?

Sounds like you need something like this...

an hour of battery time isn't a job for an UPS.

Yeah I assume you'll have all this equipment on some kind of rolling cart, I hope that's true lol

Thanks for the clarification   Like I said, I suspect that will be ok though.  If you pull, say, 100 W at idle continuously for 1 hour, that's 1/3 of the power gone, meaning it could run at 1000 W for 2/3 of 10 minutes, which is exactly 20, 20 second bursts.  If you only need 10, and if you use less power than that (don't work the laptop hard at the same time), and if idle is more efficient than I estimate, then all of that is just bonus time.

 

From the link I posted earlier, here's the runtime of that unit in minutes at different loads:

@Ryan_Vickers @Eigenvektor - yes, on a cart, printer, UPS, laptop with some spare space to write on stuff

The laptop has its own battery that will for sure last more than 2 hours, so you don't even need to connect that to the UPS? Just the printer then. Look at idle consumption of the printer, and add time at max power draw.

Not with this Xeon E2276M, if idle and doing nothing it "says" 5 hours.  Once I hit calculate, it drops below 1 hour battery life.  4k screen etc...fancy ass laptop lol

 

Technically no I don't have to be connected to the UPS but I need it to be an option.  Having the options so that any issues arise I can still be successful is part of this being put together (and why the price isn't an issue for my company as this investment will yield return very quickly)

Also one thing of note, UPSes tend to charge pretty slowly. You didn't say how much time you could plug in between those 2 hour stretches, but you can't expect to drain 60% of a UPS's battery and it be full again after 1h plugged in like a laptop would.

but it won't be calculating all the time, will it?

Negative, but each time I calc its a noticeable battery drop.  It will be calculating a lot, as I build scenarios then piece together the best puzzle for revenue every 24 hours (unique setups, equipment times etc)  If there is an option that costs $1k and it will meet my needs that's what Ill get

Particularly if you do go through with getting a lower power draw printer, since that's the main consumer here, I think this unit will be perfect.  If you need more power though, you start to get up into professional things like what Linus installed at the office, and of course the price could easily hit $1k or more for that.

The most feasible will be replace printer with low power and likely get a unit like you described so its overkill

I went and looked up a random inkjet https://store.hp.com/CanadaStore/Merch/Product.aspx?id=K7G93A&opt=A2L&sel=PRN

and the power consumption is 14 W while printing and <4 during everything else, so it really would make a colossal difference in runtime.  With this plus the laptop, you should be able to get 2 hours easy.

Thank you for spending your time on this (and everyone in this thread!).  I was at work the whole time, between my duties trying to communicate (and sometimes poorly) with you guys.  Ill just move to this option (or like it, whatever IT will approve since it wont be network shouldn't matter) but stick with the UPS you originally posted.  I wont have an issue pushing a $600 investment.

I think that would be best.  Theoretically the big printer would work but these smaller ones are not expensive and would really lighten the load which obviously is a good thing.  Also just to be clear, the printer I linked truly was chosen at random, I'm not recommending it specifically, just using it as an example of how much less power they use.

I assumed so Was going to source one that holds at least a full ream of paper at a time, with a good quality print and MUST print extremely fast (reason I use the M506)

I suspect in the end your speed requirement will be what decides the model then.  Compared to professional laser printers, ink jets aren't generally known for speed but they do vary quite a bit from model to model.

I have no knowledge on this subject today, but I will by Monday

You still haven't commented on that - it could matter for device selection.

Truth - Overnight would be the real time, and in between other stuff I do (reliant on me remembering to plug it in, which I don't want to bank on so thanks for reminding me of this post you made) - if you have an opinion on model with information on what I can expect (especially on low power printer as discussed above) Im all ears
