How to choose right  adapters is always a very important topic for the person who want to buy a new adapters for their favorite notebook, All new laptops come with adapters. Adapters are used for charging laptop batteries and also used to supply power directly. There are occasions which we require to buy an adapters. Most laptop users travel, for they travel to Europe or US they require adapters that take 100-240 voltage input and output 16 voltage or 19 voltage.

Choosing the right laptop adapters is all a matter of voltage,output power,and proper connection.If all of these things do not match the original specifications of your current adapters,then a new adapters will likely do not work on your notebook and may potentially cause a lot of damage.In the end,most laptop  adapters have a list of computers they are compatible with and a list of part numbers that will work per laptop model.

Let us present 3 easy steps to know how to choose right adapters

The first thing to consider in a  adapters is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the notebook. A sticker may be affixed with this information and other similar laptop specification listed. It should be a number with a V such as 20V. This information is also available on the original adapter, if it is available to you. If you do have a current working  adapters then your best bet is to buy the same exact part number that is on the laptop  adapters  itself.

for the users who will travel abroad especially to Europe and Asia. You would need adapters that compatible with 220-240 voltage also. So it would be wise, Always look for adapters accept 100~240 voltages. 100~240 voltages adapters will go with you worldwide. You do not need to carry 2 adapters anymore!!!

The second thing to look for is the current output needed for the  adapters. Different laptops were designed to consume power varied by equipments such as CD-Rom, LCD size, CPU maker and CPU speed. You require to use the “matching voltage” . Only use the adapters output the matching voltage of your laptops. You can easily locate your laptop voltage. Just for example, it may say something like 3.5A, 750mA etc. This number will ensure that the power going to your notebook will be acceptable and keep it operating normal. Not paying attention to either of these numbers could cause the electrical systems in your laptop to malfunction and stop working altogether, Mostly, voltage is printed on your laptops. You also can check your laptop manual.

Once these two issues have been settled, if you do not want to get a universal adapters,the other important step is finding the right “tips” , Different laptops have different connectors. You need the right tip for your laptop. This is very simply to find. Basically, laptop adapters comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet. The other end is called “TIP” which you will plug this tip into the “DC IN” in your laptop.The voltage and output current of the adapters will not matter if it is not able to be connected. I suggest and think the best way to go is buying a sample of replacement laptop ac adapter with the identical part number directly from the manufacturer. Another thing to consider is whether you want an AC adapters or DC adapters. An AC adapters is made to be plugged into any standard electrical outlet such as those in a home or office. The DC adapters is made for automobile use.Your laptop won’t work on the wrong tip. You can only use the ” matching Tips”
Warning: DO NOT try to force it in.

After reading above content,i think you should know how to choose right adapters,now you have basic knowledge to find your laptop adapters.

A fourth type splits the cord from one plug into two or more separate cords. A fifth type of  HP elitebook 8440p adapters cord allows a vehicle’s cigarette lighter to be used as a power source.

Many electronic devices have the capability to run on battery power. The HP elitebook 8440p adapters cord allows the device to draw power from an electrical outlet rather than its battery. This both allows the battery to recharge and prevents draining the battery while running the device.

Peripherals for cameras use an adapters cord to link to the camera’s 10-pin accessory connector or other interface type. This type of attachment may be most commonly used for attaching a flash to the camera, but it can also be used to, for example, attach a GPS device to a camera. In the realm of computer peripherals, a male-to-female HP elitebook 8440p cord allows an external computer monitor to be plugged directly into a computer, taking up one less wall outlet.

HP elitebook 8440p adapters cords that change plug type come in different varieties. Two main types are the ones that simply convert one type of plug to another and the ones that do the conversion but are also intended for a very specific product connection. An example of the first type is a cord that converts a 20A plug to 15A plug and can be used in any situation in which it is needed. An example of the second type is a camera adapters cord that converts the 10-pin built-in connector to a 2-pin system, but is specifically made to connect a Nikon® camera to its associated motor drive.

To split a single outlet’s capabilities, allowing it to be accessed by multiple plugs, a “multi-outlet adapter cord” can be used. This type of cord serves a similar function to the outlet strip, but instead of being configured in a rigid rectangular box, the outlets are at the ends of cords.

There are a number of devices that can draw power from a vehicle’s cigarette lighter, given the proper adapters cord. GPS locators, for example, may be both powered and charged this way, often with a 12V adapters. There are also adapters cords for laptop computers, iPods®, MP3 players, cell phones, radar detectors, portable cassette or CD players, and boom boxes. In addition, adapters splitters are made for vehicles.

Along with making sure that the plugs are compatible, a true universal power adapter will also help to convert the type of current available within the country to a type that is compatible with the electronic device. For example, if a handheld device or laptop requires direct current to operate properly, but the individual is traveling in a country where alternating current is the norm, the Hp probook adaptor will compensate for the difference in voltage and cycle of the electrical current. This makes it possible to use the device without damaging the components.
