Using Backup UPS as Power Invertor?

[Art]

Is it feasible to use a Backup UPS device as a power inverter? Not for
continual use but for occasional, s.a. 60 min at a time to run a laptop,
battery charger for electric drill, etc. ??

60 min might as well be "continual" as far as loading is concerned.

:My network UPS is an APC rated at 180VA (or so) which runs from a sealed
^^^^^
:lead-acid (SLA) battery. It will keep the network (DSL modem, router, 8-port
:switch) running for over an hour - not quite as long as the laptop battery
:lasts...

180VA?? Really?

Have a nice day,
