Portable Battery For Desktop

[mustardgas]

Hello.

Are there portable batteries available that are suited to power electronics, such as a desktop? I would also need this battery to power other items, such as a lamp. Is there such a battery that you can just plug your electronic device into and get long-lasting power from?

Thanks.

Uh, I highly doubt there are any portable batteries that can power those items for long durations of time.

Your average cheap UPS will power your computer for like 5 to 10 minutes max. The most expensive ones ($3000-5000), will crank out up to like 8000 watts of power. They are also 100+ lbs.
