Comparison of the original power supply and the so-called OEM power on the market :

The differences:

1: The price difference:The price of OEM Power Supply is cheap; while the original power supply is expensive. Let's take the 65W power supply as an example: A OEM power supply is about 20 yuan or so, while the original power supply is about 60 yuan. Laptop Accessories

2: Power: On the market, the proportion of good OEM power dissipation is about 30% (the difference between the proportion is even higher); the original manufacturer's power ratio is less than 10%. Take the ordinary 65W power supply for example: the OEM power supply with a hour power loss is more than 22W, the original manufacturer power supply to an hour of loss is less than 7W. Calculated in accordance with 10 hours a day, the OEM power electricity losses more than the original power supply 150W. It means that in 10 days OEM power l power losses 1.5 kWh more than the original one. And It will be 4.5 kWh more in a month. Nowadays the electricity in public electricity is 0.65 yuan / kWh. The use of OEM power will take you 3yuan RMB more than an original one. And that also means 36yuan RMB a year. laptop parts

3: Life is different: Usually the domestic manufacturers OEM power's life is about(the bad ones may be sent to repair in 3 months), while the original power's useful life is more than 5 years.

4: EMI (European power electron beam radiation safety indicators) indicators of differences: Usually the domestic OEM power supply is never has the EMI radiation safety indicators insecurity. It has the to our bodies, while the original manufacturer of power all through the Europeansafety testing standards, EMI is complianced. It's radiation to our bodies is within the safety standards!

5: Safety certification is completely different: the original power's LABEL (label) which means the product is in full compliance with the safety standard certification in many countries around the world and is fully achieved in many countries of the world imports of product safety certification licensee is not casually pasted everywhere. It is a sign of a quality and safety! Domestic OEM power supply usually easily find a printing factory which may not have taken any certification standards to print label and stik it up. Theproduct's safety and quality without any effective supervision and protection, and problems need to produce manufacturers bear the joint responsibility!

6: the size of the manufacturer: the original power production enterprises to large manufacturing plants, well-known enterprises around the world; lines and first-class production equipment, while the domestic OEM power production plants are all small underground factory.

Similarities:
1: Overall: Domestic OEM power supply and the original power supply look almost the same; if not, it cannot deceive the customers;
2: stickers counterfeit: Domestic OEM power supply will usually find the underground factory printing which is similar to the original power supply safety labels (LABEL) in order to show that it has the original power use.
3: the original shell which has a brand identity
4: The original factory using ultrasonic welding, damaging the shell when it is opened. While the OEM is stuck by glue, some are ultrasonic welding.
5: Case Material. The original case felt fine, uniform particles, matt. www.laptopaccessories.asia

People who use the computers are more and more, and how to properly maintain your laptop battery is also more and more concerned. In the following text I'll talk about this aspect. Laptop Accessories

A. Misunderstanding one: There is no need to charge the battery before it is running out.

Notebook batteries are now lithium batteries. Lithium batteries, run out of battery again for a long time filled with do not have any role, or even harmful. Because lithium does not exist in the so-called "cache effect", only the early nickel batteries have this feature. Laptop battery life in general with the man-made damage, or natural life. Basically, the battery life are fixed 300-600 charge and discharge times, generally available 2 years.

B. Misunderstanding two: when the power is connected, the battery can pull or not pull

Pull or not pull depends on the actual usage: Connect the DC power at the same time do not disconnect the battery and the battery does no harm, because the battery is fully charged, will not accept any electricity into the power will be directly to the laptop power supply supply system. But when the laptop high-speed operation, the internal overheating is best to remove the battery, otherwise it is harmful.

C. How to charge the laptop battery properly.

We should avoid the battery is run out of recharge, because this will give the battery a lot of pressure which will resulting in damage. A more feasible approach is to charge about 20-30% of power remaining. In fact the notebook lithium battery in the number of "light / charge" is limited, all used to recharge will significantly shorten the battery's life. At the same time, the battery should be charged in a dry place, The heat problem, which also is the enemy of the battery.

Tip: useing of mobile phone battery is different from that of laptop battery, many people may experience in the use of mobile phone battery to determine that the laptop battery should be all used up recharge, this idea is not true.

D. How to protect the battery which is not in use for a long time

What should we do in protecting a laptop battery, put photoelectric or otherwise. laptop parts

Put the photoelectric long-term preservation, the batteries will lose activity, and even lead to the control circuit protection self-locking and can no longer use fully charged, long-term preservation will bring safety risks, the best way to save is the will power to about 40% and then stored in a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take the battery out with time, can guarantee the battery good state of preservation, but not so the battery is completely lost and damage the battery and even lead to the control circuit protection self-locking and can no longer use fully charged, long-term preservation will bring security risks, the best way to save is the will power to about 40% and then stored in a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best way to protect the battery is to take the battery out at least one month a year, which can guarantee the battery's good state of preservation, and protecting it from damage by completely lost.

E. Several measures on extending laptop battery's working hours

1> to reduce the brightness of the screen: you can use the fn + down / up key combination to quickly adjust brightness (specific the fn + which keys need to see their own laptop).2> use of standby, sleep and other functions: when a long time without a computer, notebook standby or hibernate, saving power and extending the life of the computer.3> Open the cpu Speedstep function, can greatly extend the battery working time: cpu speedstep function is the default in the bios to start when using the battery, cpu will automatically drop the frequency to use to save energy. If not open, you can boot into the BIOS, press F2 to find the Performance settings Speedstep the Enable to Enabled.4> when using the battery, try to turn off the wireless, Bluetooth and infrared port. Removed without the use of peripherals and avoid enable large 3D applications, games, etc., to reduce unnecessary battery consumption. www.laptopaccessories.asia

In fact, power ac adapter is the protagonist. We all know that choosing a power abundant, stable and reliable power supply adapter is assembling a DIY desktop basis. The same is true in terms of the notebook. Only with the power adapter and the current abundance, stability, good adapter products in order to fully ensure the laptop's life and stability. And we choose the laptop ac adapter, must not be evasive, select some brand-name products. Best to buy the original adapter, if you think the high price of these adapters, HuntKey, the Great Wall and other third-party universal power adapter can also be considered, but must pay attention to matching. laptop ac adapter

Why adapter to be used as sealing structure sealing high-temperature plastic housing is the main cause of laptop, notebook, why not use metal or cooling holes in the shell open it? Do not use metal shell of the reason is simple, because there is 220V power adapter voltage, by using the metal shell, then shell fall and other factors may cause electric shock and electricity short-circuit event. Without open vents, not only in order to ensure the strength of shell, but also to avoid the outside of the water, dust and other debris into the adapter. Balance, the existing power adapter is still used in sealed plastic shell, and the use of ultrasonic welding or glue to be closed. And now here give three very important points on laptop ac adapter. Laptop adapter

First, the adapter type, for example, the model is Fengyun adapter PA-1650-66, it tells us some information, that is, its manufacturer, wattage, etc., PA at the beginning of the company in general is produced LITEON, 1650 is Description this adapter is 65W, and 75W of 1750 is, 90CD/SB is 90W of;
The second is that the adapter INPUT (input), common in China in general is 100-240V ~ 50-60Hz, indicating that Fengyun adapter in 100V-240V voltage below the normal work; third is the adapter OUTPUT (output), two figures can be calculated very quickly get this adapter wattage, such as the adapter, 19 * 3.42 = 64.98, illustrate this is to 65W
Most laptop power adapter suitable for 100 ~ 240V AC (50/60Hz). Most notebook computers are basically regarded external power supply, power cord and with a host connection, this can reduce the size and weight of the host, only a handful of models built to power within the host.
In the power adapter has a nameplate above marked power, input and output voltage and current were measured, with particular attention to the input voltage range, which is the so-called "travel power adapter," only if the mains voltage 110V countries, this feature is very useful, some parallel laptop is sold only in the origin, there is no such compatible voltage design, or even only a single input voltage of 110V, 220V electricity in China will burn voltage plug. http://www.powersshop.com

Rapid proliferation of notebook computers made a lot of people's lives more convenient, but a new trouble has come one after another, the high heat areas such as keys, mute the effect is not ideal, single cell carry around a lot of trouble, etc., really want your love is not easy. But today I want to talk about the main and laptop ac adapter, because that is attached to supplies, while closely related with people's lives. laptop ac adapter
Although for most users, laptop adapter is not needed to buy the product, but almost all of the people think is troublesome notebook adapter. Often inconvenient to carry around because of the power adapter, and forget to carry and difficult to find suitable alternatives, thus affecting the normal work and study. Most laptop users do not want to have a power adapter, but for various reasons, had to abandon the purchase plan.

So what causes a lot of users can not have a second power adapter it? To this end the author has visited the market, we find the real crux of the matter, following on to share their look.

Each brand has a different power adapter voltage and current, which brings difficulty for the matching. For the less knowledgeable players, will have to buy them some in difficulty. Therefore, strengthening the adaptive capacity of the power adapter into the future direction of development, perhaps in the future just after you forgot to take a power adapter can be used normally.
Different interfaces of different brands, brands with a variety of interfaces with no power adapter, pick up more trouble.
For the notebook power adapter, the output voltage and output current may be different, but also by strengthening the adaptive capacity to make up. Once the interface used to connect laptop is not the same, it will bring more trouble, need to further increase the power interface types, resulting in cost of the upgrade. How to make laptop power connector, like mobile phones all use the same mini USB interface, unified enough, I believe with the progress of time, this day will come. Laptop adapter

Seemingly homely notebook power adapter has implied many ills, in practical applications we have to pay more attention. In order to enjoy the convenience while minimizing unnecessary to pay, and make sure you have the original adapter with the same stability. Laptop power adapter is currently compatible with a meteoric rise, and has huge market potential. It is for this reason, the future will have more power manufacturers joined the fray, the price of laptop power adapter will surely be reduced. Of course, the four points mentioned above the lack of laptop power adapter, which over time will slowly disappear, then you may enjoy more affordable. http://www.powersshop.com

It is an important chose your laptop accessories, like power adapter. Power adapter in the purchase day, we will often meet the original and the price difference between non-original more, going to choose at this time? This article briefly describes our purchasing power ac adapter which can use as the hints when purchase and source. Hope it will be helpful. laptop ac adapter

Supply voltage, the output current is different, can not be used on the same laptop. The basic principle is that a large nominal current of the power supply adapter can replace the small nominal current of the power. Estimated that people will think, that a large nominal current of the power supply will burn your dear laptop, because it is rally do not proper. How much current is actually the same in the case of the voltage depends on load, yes, just please think of junior high school physics then you will know.

Usually the original power adapter higher than to the power supply non-original one?

Theoretically, he original power adapter is certainly better, but the actual use may not feel the difference. The device usually has a voltage input range of security, such as a 2.5 mobile hard drive, it is plus or minus 5% of the required 5V, too high or too low, the equipment protection circuit will stop working. If the protection circuit starts, it shows that before this, your machine has been designed close to or more than it can bear the maximum or minimum, which is the life of the machine are influential. (Of course, here referred to non-original power, or good workmanship, poor quality products, do not mention.) Laptop adapter

How should I keep or store my laptop ac adapter while I am mobile?
When you are packing your laptop adapter into a bag for transportation, you have to remember that the wiring attached to the ac adapter can loosen and break, causing a bad connection between the wall outlet and your laptop computer. It is important to remember never to coil your wires around the laptop power adapter. Always bundle up the wires in a coil and make sure not to bend or force the movement of the wires attached to the laptop power adapter, as this may cause the connections on your power charger to come loose or break. http://www.powersshop.com

How can you find a right laptop AC adapter? First learn something about it.

The AC adapter is an integral part of any laptop. The laptop AC power adapter usually has two main parts. The first is the "brick" or the largest part of the adapter, which is the transformer that does the conversion from AC to DC current and connects to the laptop through a cable. While laptops are able to run on battery power, without the AC adapter, there would be no way to recharge the battery. The power cord normally comes in a couple different varieties depending on the specifications of the AC adapter. With some laptop AC adapters, this cord is permanently attached instead of being removable.Older laptops often had the convertor or transformer included in the laptop itself, but this added unnecessary weight.A desktop replacement laptop, with more power-hungry components, may draw 185W or more during heavy use. Therefore, it also usually requires a more powerful transformer, which translates to a larger "brick". laptop ac adapter

Manufacturers specifically differentiate the tip sizes of this cable to ensure that users don't plug an incompatible adapter into the wrong laptop, which could cause damage to the laptop or laptop AC adapter. The transformer is often significantly larger for more powerful laptops. Laptop AC adapters provide power to the laptop and the battery by converting the electricity coming from an outlet, which is AC (alternating current), into DC (direct current) power and outputting it at the correct voltage. This is due to the fact that a more powerful laptop requires more wattage. For example, a small netbook, designed for power efficiency and better battery life, may only draw a maximum of 40W of power. Laptop adapter

The second part of the laptop power adapter is the power cord, which connects from the brick to the wall outlet and delivers electrical power to the transformer. When shopping for a replacement for your laptop AC adapter, it is important to find one that is compatible with your specific model. Use a parts locator tool online to find the laptop AC adapters that are compatible with your model. This ensures that they provide the correct voltage, and that they have the correct tip to be used with your laptop or notebook. As mentioned, using an incorrect laptop or notebook AC adapter could cause damage. http://www.powersshop.com
