Computer power while boondocking?

Thanks for all the input! My wife will be working in the RV during the day---running two computers and a Verizon jetpack for 8+ hours/day while I do the important stuff like operate, maintain and test the barbeque, golf clubs and fishing poles. She may also use the cell phone as a hotspot but needs phone access for her job so more likely will use the Jetpack (no unlimited data unfortunately). After reading the replies I will go with PSW inverter. Now its a matter of deciding what size. Looks like I should err on the side of bigger rather than smaller. I will look at solar panels to recharge my 2 6-v house batteries-thanks for the recommendation. Lastly, can anyone make a guess as to how long I need to run my 5500w genset to recharge the batteries?
