Hello,
We have about 100 users that need to use their personal laptops for extended periods of time - 2 x 3hr session 1hr apart is the worst case scenario. We have asked them to bring 2nd/extended life batteries but we are expecting many of them may fail to do that for one reason or another. We only have 8 power sockets in the room and we are not allowed to use laptop charging cabinets or power strips. I know there are some universal portable chargers/batteries but not sure what would work or where to look for. Any ideas on a good portable powering solution for laptop(s) that would last 6 hrs. Also, users will need to access wireless internet, so this would put extra burden on the batteries.
Thank you!

many.
generally, each of these powerpacks give around 3 hours power to a laptop (depends on the power requirement of the laptop)
what is your budget?
if you dont have control over the laptop models, then supplying low voltage is out.
you need to supply main line voltage (110 or 220),
how about a deisel generator (cheap) or a UPS (expensive)
hathehariken.
then a large UPS is what you are looking for.
even an inverter will work.
you will be wanting a 220 volt, 65 to 80 ampere inverter
nominal load should be maintained at 60-70% max.

for this you will require deep cycle batteries (many).
if you require i will calculate and tell you how many batteries you will require.

for inverters, instead of "one big" inverter you can also have "many small" inverters

each of these will power at least 6 laptops.
of course they can share the same battery array (easy to recharge), or each can have its own battery cache (pain to recharge)

ps. there are ultra quiet DG sets available out there. you cant hear them operating from 10 metres away.

You're going to run 100 users from 8 electrical outlets, and no power strips are allowed? Is the person in charge of this operation thinking of the ramifications clearly?
If the building is incapable of providing the power, get an external power generator and run it through a line conditioner, and from there, supply power to the users. I think upgrading the power in the location is the right way to solve this, and anything else is going to be a makeshift solution.
