Run time for UPS

[ErnieAsksQs]

I go to events where there is no electricity. I need a power supply to keep my laptop and monitor showing video clips for about 8 hours. Any suggestions of what I could use?

8 HRS is extraordinary - - the object of a UPS is:

1. to force a controlled shutdown while power is still available -- OR
2. to give the user time to end tasks, save all docs and then shutdown.

This is NOT the same as a mainframe powerstation used to avoid outages.

Think it through. How many watts for system plus monitor? 200? Over 8 hours? Conversion losses to 115v? Maybe something like https://www.apexbattery.com/ub8d-ge...battery.html?gclid=CIPRx_f1kNMCFdaEswoda6sLbA plus an up-converter like https://www.lowes.com/pd/Schumacher...35a2bb1e377f&gclid=CO7Kovz2kNMCFY6KswodHOMLmw

You will also need a cart to move it.
