Be careful with these gadgets (they're called inverters). Most of them
synthesize the 60 Hz AC power by stepping the voltage up and down
through a series of discrete steps. This causes the voltage to consist of a
series of very fast voltage rise and fall
times. To most computer power supplies, these pulses look like spikes and
the computer's power supply will try
to suppress them. This, in turn, looks like a brief short circuit to the
inverter. If you're lucky, the inverter will have a
circuit breaker that'll pop and protect everything. If you're not lucky,
lotsa stuff, possibly including your computer, will
get smoked.
Very few inverters provide a true, smooth sine wave output. The only way to
tell is to look at the inverter's output on an
oscilloscope.
A good way around this problem is to put what's called an isolation
transformer between the inverter's AC output and
your computer. The transformer will smooth out the power and eliminate the
problem.
I don't know your level of electrical knowledge, so feel free to keep in
touch and ask what questions you need answered.

Subject: [MV] 24 volt to 110 converter
Can someone recommend a 24 volt to 110 converter? I'm only going to run
a computer off it so it shouldn't draw much amperage.
Thanks,
