Dell latitude laptops have OEM chargers that can run on 10-16VDC. The E6520 I use as a server takes about 6W to run at idle. Grab a 12V battery and a 5A SLA Charger, run your router/modem/server directly off the battery.
UPS's take about 10W to just power the inverter. This gives up a lot of the battery capacity not to mention the losses from converting your power 2 times.
