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 brick and line power adapter.
The appliances that are battery backed and chargeable use Power Plug Adapters. They’re 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.
Apart from these power cable types, the buyers ought to know various other specifics about the charging cables such as the voltage and power output.

A power plug adapter is exercised to convey power into the battery of electronic devices such as digital cameras, laptops, and game consoles. If the power adapter malfunctions, you need to change it with a well-suited adapter that follows the essential voltage necessities of your appliance. Using a mismatched power plug adapter may spoil the device, so it is significant to understand the appropriate way to replace it. There are scores of electronic gadgets in households such as cell phones, cameras, and music players. More or less, all of these are run on power adapters, the well-known black, stout wall-plugs. If you lose these adapters, you can get substitutes. Through a power strip, you can keep them ordered. Also, if you use them shrewdly, you can reduce your electric bill.
Power plug adapters are available in different shapes, sizes and ratings, but three important factors to be considered are:
Current Rating: Electronic appliances usually consume power between 100 milliamps and 3000 milliamps. The power adapter provided with the electronic appliance will convey enough current.
Voltage: Power adapters usually provide voltage between 3 volts and 24 volts.
Plug Variety and Polarity: Nearly all power adapters contain two-conductor plugs. The polarity varies among dissimilar models
some contain a positive inside pin with a negative outside, while others have it the other way around. A multi-use power adapter permits you to switch polarity, so it will work with the widest array of equipments.
Verify the product documents for the specifications of the power plug adapter that you require. If you have a spare power adapter, check the output voltage of the adapter for voltage specifications. The thumb rule is that the voltage of a power plug adapter must be within 10 % of the original voltage of the AC adapter of the appliance. For example, if the voltage requirement of the original adapter of the appliance is 120 volts, then the power adapter you would exercise is supposed to have a minimum capacity of 12 volts.
Always verify the wattage necessities of the appliance. The wattage competence of the AC power adapter must not be lower than the mandatory number of Watts. For example, if the appliance requires 75 watts of power, you will require a power adapter that is greater than or equal to the required watts, which may be 80 watts, 90 watts or higher. Make sure the AC adapter plug suits the power port of the appliance because power adapters are available in different sizes and shapes. Hook up the power adapter from the power port of the appliance unswervingly into a functioning power outlet. Do not exercise secondary power sources like surge protectors.
Make sure if the appliance is charging. The power LED light is supposed to ascend indicating that power is being encumbered to the appliance. If there is no indication of power, remove the power adapter and plug it again into the power port of the appliance to make sure that the power adapter is connected appropriately. If this does not resolve the problem, immediately remove the power adapter from the appliance because the power adapter may not be working.
Note that even though you can exercise any well-matched power adapter with your appliance, it is always best to buy one that is certified and suggested by the appliance manufacturer. Although a well-matched power adapter may work, it may impose damages on the appliance in due course.
