Any reason to select (or not to select) a Universal 150W Auto DC / AC
Power Inverter Adapter for my ASUS Z71V laptop over buying a car

Is one any better than the other? The inverter cost less (about 1/2 the

It looks like the ASUS product is more compact:
Input: 11-15V DC
Output:    19V DC, up to 75W / 3.95A max

3.74in x 1.6in x 1in (95mm x 40mm x 25mm)
Smaller than a computer mouse

But, using the inverter would be just like plugging my existing laptop
AC adapter power cord into a wall receptacle at home - wouldn't it?

yup - we bought a Radio Shack inverter for longer car trips - works

So, this would probably be fine:
APC Mobile Power - Power converter - 140 Watt - external - 1 output

Generally, an AC inverter will work, but there are a few cases where the
waveform of the inverter is incompatible with the laptop power supply.
However, the inverter is an inferior solution, other things being equal.
  It is far more wasteful of power (although that is generally not a
consideration), and it means 2 devices instead of one, and lots of wires
where fewer wires would do.  But it will usually work just fine. wrote:
