The laptop adapter purchase recommended

1.Selected brand:
Substandard products sold online are cutting corners, normal use should be no problem, once the unexpected will burn your laptop, and to cut dozens of blocks has burned thousands of pieces of notebook more harm than good, (cut corners The common practice of arbitrary standard Liteon laptop adapter, such as the actual 19V3.42A, but marked 19V4.74A, this will lead to charging is very slow, or even damage the laptop battery and laptop also remove some protection, this is even more horrible and unexpected on burned laptop.)

I suggest you ample funds, you can buy a professional brand (ie professional Asus laptop charger brand, rather than what the power to do the kind of only such professional brand-specific products was not on the battery and damage to the laptop, and state-of-the-art protection circuit.) such as N17908 the (Asus’s brand) (though these brands are mainly in Europe and North America sales, rarely found in domestic retail)

2.points clear purpose:
Want household and office with sold to buy a home (AC use), you want to use the car, buy a Laptop Car Charger, you want to use in the aircraft on the basis of the vehicle with a aircraft head on it. Home, car, airplane, wants to take into account, buy a combo or triple. However, if you do not want a computer bag multiple weight, you can put in the house, put a car, put a office, so that you can not bring to bring plug to plug go, more convenient and can give around with .

3.points clear of voltage, current and connector:
Look at the original laptop brand, original Acer charger behind the label, write V, the number of A (generally written in the the OUTPUT behind), the compaq charger connector is probably round or square, or porous do to himself probably several, they are not to buy the wrong, or even been fooled.

For example, you originally attached to the hp laptop charger 18.5V 3.5A that have to buy the output 18.5V As for the current higher than 3.5A can. hp 710412-001 laptop adapter.Merchant Referral 18.5V, you’d better not, Although you can charge the special circumstances of emergency can charge, a long time to be battery and laptop causing damage. That voltage accuracy (can not be the way high or low), the current can be high (but the higher the more expensive).

Purpose:
1.AC (such as home, office with AC called AC)
2.DC (such as the car, on the plane with the DC called DC)
Instance Acharger the of ALS-185A35C (number followed by the letter A is indicated by AC current)
For example Acharger’s of ALS-185D35C (figures behind the letter D is for DC)
(Find Acharger product numbers will be preceded and ALS, ALS is the meaning of the single-band Gateway laptop charger
Singel-output Fujitsu Laptop Adapter combination of the first letter abbreviation)

Recommendation to buy Laptop AC adapter

Posted by admin on August 19th, 2014

Choose the right brand
Many are cutting corners online selling substandard products, the normal use of what should be no problem, once an accident occurs it will burn your laptop, saved tens of thousands of pieces of the block was burnt notebook harm than good, (jerry common there are standard practice chaotic power, such as real only 19V3.42A, AC Adapter For Toshibabut standard 19V4.74A, this will lead the charge very slowly, or even damage the battery and notebook computers. still put some protection removed, this is more terror, unexpected will burn off the laptop.)

Under the circumstances suggest that you have sufficient funds, you can buy a professional brand Toshiba PA3755E-1AC3 AC Adapter (that is, only a professional brand for notebook charger, rather than what kind of power do so single-minded brand of professional products for batteries and will not laptop damage, and advanced protection circuitry.) such Icharger, Acharger (AATUU brand), etc. (However, these brands are sold in Europe and America, the domestic retail rarely found)

Points clear purpose
Wants to household and office use to sell a home to buy (AC use),Toshiba PA3755E-1AC3 AC Adapter you want to use the car, you buy a car, you want to use on the plane with a car on the basis of a aircraft head on it. Home, car, airplane, wants to take into account, to buy a combo or triple. But if you do not want a computer bag and more weight, and you can put one in the house, put a car, office, put one, so you can not bring bring, plug to plug go, more convenient, but also to the people around him with .

Distinguish between voltage, current and connector
Look at the original laptop is which brand, the label behind the original chargers to write how much V, the number of A (usually written on the back OUTPUT), charger connector is probably the round or square, or porous, his heart probably do a few, they are not buying the wrong even been fooled.

For instance, your wife is 18.5V 3.5A charger output 18.5V That must buy, as for the current higher than 3.5A all OK. But if your business is best not to 18.5V recommended, although you can charge the special circumstances of emergency can be recharged, a long time will damage the battery and notebook computers. That voltage must be accurate (not the way high or low), the current can be high (but the higher the more expensive).

What Is a Universal Power Supply?

Posted by admin on August 1st, 2014

universal power supply is a device that steps 110 or 220-volt AC household current down and converts it to DC so it can power an electronic device, appliance, or some other electric equipment.Such as, Samsung PN3014 Adapter. It consists of a transformer encased in a box fitted with a wall plug on one end and a cord on the other. There is a switch on the box that allows the user to select the output voltage, usually in a range between 1 and 20 volts, and connected to the output are a series of diodes to convert the AC current to DC. A universal power supply comes with a variety of output jacks, each designed to fit the input of a device that will run on one of the selected voltage settings.

Laptops and household appliances, as well as audio and video and other other electronic equipment, come with their own mobile power supply so you can run them from a household circuit. The transformer and diodes in the power supply are necessary to protect the delicate electronic circuitry in these devices, and losing the power supply, an all-too-frequent occurrence, renders them inoperable. There is no standard input voltage that is appropriate for all devices, so having a universal power supply on hand is an easy way to regain the use of one if its power supply has been lost.

A transformer has an input and output coil, both wrapped around a central core, and the ratio of the input voltage to the output voltage depends on the relative number of turns of these two coils. The switch on a universal power supply alters the output voltage by changing the position of the point of connection to increase or decrease the number of output coils. The diodes convert the current from AC to DC by passing it in one direction while canceling the current in the return direction.

While a universal power supply can be used to power a variety of different equipment, there isn’t one that is appropriate for all devices. Before purchasing one as a substitute for a laptop power supply or a supply for a sensitive piece of electronic equipment, buyers should check the range of voltages for which it is rated, as well the output jacks that come with it, to make sure it will work. The power supply output current rating should also be the same as that of the device for which it will be used.

Buy the right Laptop AC Adapter

Posted by admin on July 7th, 2014

All new laptops come with AC adapters. An AC adapter is a small device that connects an electronic device to a wall outlet. Laptop AC adapters are used for charging laptop batteries and also used to supply power directly. It enables electricity from the wall outlet to travel through the adapter into the device, thus providing it power and giving it the ability to operate. If your AC adapter breaks, this can be a major problem.

One big misunderstanding will occur when it comes to replace the AC adapter for your laptop. That is, you have to purchase the replacement AC adapter from original manufacturer. But actually, this is not necessary. You could save money on a completely compatible and 100% reliable replacement AC adapter for your laptop if you buy it from a secondary AC adapter retailer. Just make sure it’s labeled for your MacBook, PowerBook, or iBook and meets your current adapter specs.

Choosing the correct laptop ac adapter 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 laptop ac adapter, than a new laptop adapter will likely not work on your machine and may potentially cause a lot of damage.

Following are some tips for choosing a right laptop ac adapter from voltage, output power, and proper connection.

1. Find the right “input 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 machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V such as 19.5V. This information is also available on the original adapter, if it is available to you.Always look for AC adapters accept 100~240 voltages. 100~240 voltages AC adapters will go with you worldwide. You do not need to carry 2 adapters anymore.

2.Finding the right “output voltage” Just for example,Toshiba PA3546E-1AC3 Laptop AC Adapter it may say something like 9.5A, 180W etc. This number will ensure that the power going to your machine will be acceptable and keep it operating normal. Only use the laptop AC adapters output the matching voltage of your laptops. Not paying attention to either of these numbers could cause the electrical systems in your laptop to malfunction and stop working altogether.

3.Finding the proper “connection” The other important step is simply to make sure the laptop ac connection fits the port in your notebook PC. Basically, laptop AC 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 laptop ac adapter will not matter if it is not able to be connected.

Also, laptop AC adapter manufacturers are now promoting “universal AC adapters”. This emerging adapters can be used with multiple devices. They can accept 100~240 input voltages and also adjust the output voltage to match device automatically.

Now, you already know the basic knowledge to find the right laptop AC adapter for your laptop.

So easy to charge control circuit is judged to have been full capacity will naturally decline. Relatively large battery internal resistance, discharge voltage drop, high speed, so the system is easily mistaken for the voltage is not enough, the lack of electricity. Found the battery operating time is comparatively short, appropriate measures should be taken.

(B) The battery refresh program to restore the battery discharge time
Brand laptop has a battery refresh program,Samsung AA-PBYN8AB we can use it to repair the battery. Example: a laptop with the battery for the nickel-metal hydride (Ni-Mh) batteries, due to the usual improper charging and discharging lead to battery discharge time is getting short, only less than 5 minutes, if carrying a laptop to work, it is very inconvenient, what can restore the battery discharge time?
The response to these circumstances, we can use the notebook official website launched battery refresh program to refresh the battery, put it Samsung AA-PBAN6AB back in the discharge time, specific methods are as follows.
(1) the use of AC power for laptops, the first official website to download to a laptop refresh program.
(2) Restart the computer, press F8 to enter the boot menu and select safe DOS mode.
(3) to enter the directory where the file you just downloaded,Samsung AA-PBWN4AB perform a battery refresh program, read the warning message, asked to insert a floppy disk, and then press Enter to execute the self-extracting operation.
(4) with this floppy disk to boot the computer screen prompted.
(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.
(6) due to the high temperature of the battery should not immediately start, let the battery cool for a while, plug in the AC power supply.
(7) to boot the computer with a floppy disk, this file will automatically run the refresh program, and asks the user whether to proceed.
(8) In this case,Samsung AA-PBAN8A the refresh program began battery refresh process back to the DOS prompt A: when the refresh is complete.
(9) Turn off the computer and charge the battery until the light turns green.
(10) The above process is repeated three times to get the best results.

In addition,The replacement samsung laptop battery has been many lithium battery failure is the failure resulted in battery packs in a power-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent in nature with weakened for a long time after some quality begin to age, while the destruction of the whole (series after) the discharge curve. Interested readers can try to open the battery pack, and the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, the replacement under the corresponding parameters of batteries can be qualified product.

As an important part of the laptop battery from birth onwards caused widespread concern of the laptop battery owners of the mobile office. With the rapid development of laptop and handheld electronic products technology, its stability, time, volume and even the number of charge cycles, charging time are put forward higher requirements, and hp dv4 battery battery technology to follow the market demand, in many has made the improvement and development.

To reduce the volume reached at the same time extend the use of time, increasing the frequency of use, laptop battery adapter and reduce the memory effect of the negative impact such purposes, taking into account the cost of the battery and the use of security, battery selection constantly refined. Cathode material for lithium-ion battery, for example, can be broken down to the lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide and other raw materials. From a technical standpoint, battery lithium cobalt oxide-based. To further enhance the product’s energy reserves,Dell Inspiron 1520 Battery the higher level of technology of lithium nickel material is expected to enter the market in 2000. But because of the limited impact of the cathode material for battery characteristics, according to expert estimates, by the year 2000, the volume energy density of the lithium-ion battery in about 400wh / l, the minimum thickness of a single battery should be between 4 ~ 5mm performance almost do not have much room for development.

On the whole, the development of alternative new generation of the Samsung N150 Battery lithium-ion batteries battery is imminent, professional battery manufacturers are also actively selection and research and development work. Great deal of attention in the new material is expected to replace the lithium cobalt oxide, lithium metal rechargeable batteries. Metallic lithium rechargeable battery are the anode material to direct new type of rechargeable battery using lithium metal, its most important feature is that the battery anode metal material reaction, can give full play to the new battery’s energy reserves reached 2 times more than conventional lithium-ion battery, and in the discharge terms of capacity, even up to 10 times that of traditional products. Lenovo computer company has been concerned about the laptop dedicated to the development of efficient battery to maintain close contact with professional battery manufacturers invest a lot of funds to conduct an independent study, efforts to provide Chinese customers with efficient, economic latestToshiba PA3904U-1BRS battery technology.

Zinc-air battery is also replaced the leader in new materials of lithium cobalt oxide, it is the negative use of zinc, very characteristic. Air zinc battery free charging, there are certain problems, but the Compaq Presario V2000 majority of battery manufacturers are actively seeking solutions, I believe that the maturity zinc battery products will soon come out. —- It can be predicted that in the near future, whether laptop manufacturers or users will face more and more efficient and more practical choice, while the number of the birth of a battery of new technologies and new materials will future battery market a revolutionary impact.

Experts predict the future of the notebook computer can do in theory Lenovo B450 battery use time more than 20 hours, the entire battery module thickness of only 12.7mm (approximately 1/2 to 2/3), at the same time the weight will greatly reduced, so that more users to fully enjoy the fun of mobile office.
