The reason I need the monitors on is because I'm playing online poker. I have 2 monitors... one is a 32' 4k Samsung monitor and the other is a 24' 1920x1200 monitor. I play online poker and have tables on those 2 monitors. I could play only on my xps 15 9520 laptop but the screen is too small. The big issue is I play a lot of tables so the amount of tables and overlapping tables makes it almost unplayable for me. Imagine having to do things on your laptop screen but you have a ton of chrome windows opened and you don't have another monitor. That is how it is for me when I play. Does that make sense? Just imagine having a lot of software opened and usually those software are opened on 2 external monitors but you doing all this on one laptop screen.
I do not want to have any downtime when a power outage happens. Because when that happens right now, I literally have to disconnect my 2 cables from my xps laptop and my 2 monitors in order for my laptop to work. The moment power outage happens, all my screens turn dark until I disconnect the 2 cables. Then everything would show up on my laptop. I then have to turn on my wifi hotspot on my iphone and connect to the hotspot on my laptop. Then I continue playing on my laptop screen with a ton of tables which is very hard to do. I would then connect my laptop to either my Anker 737 or Dell PW7018LC powerbank until it run out of battery or until the power comes back on. Now when the power comes back on, I then have to connect my 2 cables from my monitors back to my laptop. So doing this causes a ton of downtime and it costs me money when this happens. If I have a power outage during the middle of the session, that is a disaster. So I unregister any upcoming tournaments when this happens.
I want a solution where when a power outage happens, I can continue playing on my laptop with 2 monitors. Then when the 5 minute break comes, I still want to have some power on my UPS so I could then use that 5 minute break to then disconnect the cables from my UPS and connect those same cables to a portable power station. Then continue playing this way until the power station runs out of battery or I'm done for the day. So based on what I described, I should get new replacement batteries for the UPS. Then buy a portable power station that has at least 1000 whr then if I want at least 5 hours of backup for my xps 15 9520 laptop and my 2 monitors? I want at least my 32' 4k monitor to work. The 24' 1920x1200 monitor is still very important though as I use 2 monitors when I play.
