Know the Plugs that Power Your Laptops! Two of
the greatest innovations of human history
Machines and Electricity. Like always, the
beauty of the creations often tends to
enslave the creators. Today, we literally live
along with the new species of electronics
surrounding us. The human race today heavily
relies on these gadgets. And just like us,
these gadgets too hog on energy sources for
their kind. Animals acquire food to derive
energy for their survival and the machines
around us are as good as being alive.
They don't acquire the food. But they do need
energy to function. So, what is the source of
their energy? Whenever our smartphone or
laptop pings and displays a notification
low battery, please connect to a charger,
we immediately realize that the gadget is energy
deprived and we need to feed it. We attach it to
a cable, a power cable cord and connect one of
its end to the device and the other to the
wall. In order to make these
connections, we use power plug adapters.
Practically, the tools are part of the circuit
that lets us charge the battery. Its other
common names are plug packs, domestic mains
adapter, plug-in adapter, wall wart, power

The appliances that are battery backed and
chargeable use Power Plug Adapters. Theyre also
used with devices having no power source when
plugged in the wall socket. The types of
power cables available in the market are AC
Power Adapters These are the adapters
generally included with your laptop purchase.
The main electrical supply is of
alternating nature and the battery backed laptop
requires direct supply of current. We plug one of
the units of the adapter into the wall
socket. The adapter consists of another
unit coupled in the circuit which is a
step-down transformer, which rectifies
the alternating current supplied by the wall
outlet to direct current power on which the
device functions. The third and the
final unit of the adapter connects the
transformer and device. And this completes the
circuit. DC Power Adapters These are generally
aftermarket purchases even though few laptop
manufacturers do provide these adapters
with the purchase. Most of the other cables
which charge the appliances from a source of
direct current do not require the need of
conversion from AC to DC. They are the simple
adapters which

we find in the car power plugs and
batteries. These adapters can charge
batteries without the need of an external
power source. Universal Power Adapters These
are also aftermarket purchases and are
somewhat costlier than the replacement of AC
power plug adapter or the DC Power adapter. In
order to accommodate all the types of
available charging conditions you should opt
for the Universal Power Adapters. Universal
chargers use different types of
interchangeable tips and pins like the
4way X connectors and six-way star
connectors also known as spider connectors.
Not just the pins and tips but the universal
chargers also provide additional functionality
across various voltages and sizes. This
makes the universal charger function virtually
in all the possible charging environments. Apar
t from these power cable types, the buyers ought
to know various other specifics about the
charging cables such as the voltage and power
output.
