First and foremost do you really need a power inverter? If you are just interested in
running your laptop from your car when you are out and about and don't have access
to a power point for example, then you are probably better off just getting a car laptop
power supply as not only are these specifically designed for what you are wanting to
do but also saves you having to worry about making sure you pick the right inverter
for the job. On top of that they are usually around the same price as a good quality
inverter so if that is all you are going to use it for then maybe have a look at what is
available for your laptops make and model.


Power inverters come in a range of power capacities so selecting the right one for you
is very important. Your power inverter needs to be able to provide sufficient power
for the equipment you want to use it with.

Here is a brief check list:

o Check the power consumption for the device you want to power
o Allow an additional 20% free board
o Add the power for all the devices you want to run at the same time

Ok, now that we have that out the way we are going to assume that a power inverter is
what you want/need and so we are going to cover the main things you need to think
about before clicking the buy button on a cheap and dirty power inverter. Before I go
any further I just want to point out that when I say cheap I am referring to build
quality, not necessarily price. While it is true you usually get what you pay for there
are some very good quality power inverters out there without the hefty price tag if you
do a little shopping around.

A typical power inverter produces a 'modified sine wave output' like the red line in the
drawing above. While this works for most appliances, light dimmers, variable speed
drills, sewing machine speed controls, some laser printers etc. will not operate
correctly with a modified sine wave power inverter.

You can pick up a cheap modified wave power inverter which will create a fairly
choppy AC power source for a lot less than the cost of a true sine wave inverter that
will replicate your homes power supply almost perfectly so it is worth having a quick
think about what you want to run from it as for some appliances a cheap modified
wave power inverter will do the job just fine, and save you having to fork out the
extra bucks.

One of the great things about electronic equipment is there is no moving parts
(although there is a fan in some models) so you can expect a long serviceable life
from a power inverter.

Having said that you will want to run a lot of electrical equipment from a high quality
power source so a true sine wave power inverter is really your only option for those
devices as otherwise chances are you will run into problems one way or another at
some point down the track and you might even cause some serious and even
irreversible damage to very sensitive equipment so it is worth making sure you pick
the right inverter for the job.

Power inverters can also generate electro-magnetic radiation that can interfere with
other electronic equipment such as radios transmitters etc. Check for compliance with
relevant standards such as C-Tick etc
