Ruggedized Power Supply
                     Ruggedized Power Supply
 Ruggedized power supplies 
are designed to be reliable, 
so that you don't have to 
worry about an accidental 
zap or a dropped power 
cord. They're typically made 
of thick plastic or metal, 
which protects the internal 
components from physical 
damage. 
Some units come with a 
backup battery and cables 
that plug into an external 
power source so that they 
can be used in case the 
primary batteries run out, 
while others are completely 
portable.

The best thing about a 
ruggedized power supply is 
that it's so durable that it's 
also incredibly compact, 
which means you can take 
it with you wherever you 
go without fear of causing 
damage to your computer 
while you're traveling.
 There are two main types 
of ruggedized power 
supplies: one that's 
designed for laptops or 
other portable devices, and 
one that's designed for 
desktop computers. While 
those are the two most 
common types used in this 
area, there are also some 
for other purposes. 
 A normal-sized 
desktop computer 
would need anything 
from 500-600 watts, 
while laptop batteries 
might only require 
250-350 watts. 
So although it doesn't 
matter much what kind 
of device you're 
powering, you do need 
to make sure that the 
manufacturers' 
specifications match 
your needs—and even 
then, there's no 
guarantee.
 But if you have some 
idea of what kind of 
power you need, you'll 
be able to find a 
model with the right 
wattage rating (or at 
least an alright one).
Another important 
consideration is whether 
or not the unit has some 
kind of protection built into 
it. If someone else is going 
to use this power supply 
frequently and potentially 
abuse it, making sure it's 
protected against shorting 
out isn't a bad idea. 
It can be done by putting 
heat sinks on the inside of 
the unit (or maybe just 
buying another unit with a 
little more insulation), but I 
suppose you could just buy 
one that already has this 
feature built in as well—but 
if so, why design it around 
the safety aspect?
