Q: I want to find out when my item will arrive after I purchased it. How do I do it?
A: Once we complete your order and deliver it to the US Post Office, we email you a notice that your item has been shipped. Included in this email is an item tracking number. You can go to: WWW.USPS.COM and paste the tracking number into their tracking system. You can also click directly on the tracking number link within the email. Most times you can find the current status of your order's location in the postal system.

The USPS does not offer tracking for International destinations. The customs-label number that you receive in your shipping notification email does not locate your item while it is in transit to your country.

Q: Do you ship to Puerto Rico, Hawaii, Alaska, International?
A: Yes, we ship worldwide. If you don't see international shipping option in the listing, please, let us know we'll fix that.

Q: How soon do you ship? When should I expect my order to arrive?
A: Shipping info and transit times is provided by us post office, what we can do is send it out ASAP, usually in same day before 2:00.
Sellers are not responsible for service transit time. This information is provided by the carrier and excludes weekends and holidays. Note that transit times may vary, particularly during peak periods.
USPS First Class (with tracking): 1-5 business days
USPS Priority (with tracking): 1-3 business days
USPS Express (tracking and confirmation): 1-2 business days
USPS International mail: 10-20 business days, sometimes may delay by the custom in your country (especially to Italy). But we always send out as a gift.
We will send you the custom# to your e-mail.

Q: Where is my item, you shipped it like forever ago?
A: Check the tracking number first, it was included in your e-mail (international shipping excluded). If it says that your item was delivered to your ACTUAL ADDRESS, go to the post office or ask your mailman, only then send us an e-mail and we gonna try to help you to find it as best as we can sitting in front of the computer.

Q: The USPS website says my item was delivered, but it's not here... What happened?
A: 1)The number one cause of this situation is your eBay and PayPal shipping information is NOT up-to-date. Your item was most likely delivered to the old address that resides in your PayPal and eBay account.
2)If the address is correct, USPS is responsible for prompt delivery of your item. Just like everybody else we go to the Post Office and drop your adapters there, hoping it will reach you as it was promised to all of us by USPS, promptly. Talk to USPS clerk first, 95% chance they can locate your item. Then, write us an e-mail.

If your item was delivered to an incorrect address that you failed to update in eBay/PayPal at the time of your purchase, your options include:
1. Contact whomever resides at that address and see if they can forward your item to you.
2. If the item is refused by whoever resides at the old address and it comes back to us, we will have to charge you additional postage fees in order to resend your item to your new (updated) address.

Q: I forgot to update my eBay Pay Pal address and the item was already shipped to me.
A: Well at this point it out of our hands. Try to contact the person at your previous address. If the item comes back to us you will be responsible for any additional charges if you still want it to be shipped to you. Please make sure that the address was updated.

  Received wrong item / Part Number is Different

Q: Why does the part number of the item that I just received not match the part/model number of the item that I bought from you?
A: When we post an item in the eBay listing title, we do so knowing that the item listed is 100% compatible with your device. Sometimes the manufacture sends us the compatible item with a label that has a different part/model number. It is difficult to always update these part/model number changes immediately, but the adapter is still compatible and should work in nearly all cases. Our suggestion is to try the item on your device (assuming the voltage, amps, and tip are a match) before contacting us. Most of our customers find that the item will work with their device just fine.

Note: One charger can fit thousands of laptops of different brands, but the laptop manufacturer would want you to believe it is otherwise so you spend your money just with them. There is no way our supplier can put different labels on one type of charger that would be described as fitting only your laptop.

Q: Why does my item not look like the one in the picture on the eBay listing?
A: The images we use are for reference only but are usually a 99% match to what you will receive. If you receive an item that doesn't match the image on our listing, our suggestion is to try the item on your device (assuming the voltage, amps, and tip are a match) before contacting us. Most of our customers find that the item will work with their device just fine.

Q: I just ordered the wrong item. What do I do?
A: Please contact us immediately!! Most times, we can exchange the item no problem if you contact us before shipment (1:00 PM Pacific Standard Time). If the item already shipped, then additional steps (and charges) will apply.

< back to top >

  Is Your Laptop AC Power Adapter Working Properly?

Like all other electronic devices, laptop adapters eventually stop working. There are many causes from excessive wire bending, exposure to extreme temperatures, or simply that it’s an aging adapter. Unfortunately there is no definitive amount of time that adapters last. Their lifespan is dependant on how much they’re used. Below we list ways of checking if your adapter has ceased working.
Check Your Laptop
Your laptop adapter may not power your laptop due to a loose connector. Make sure all connectors are inserted correctly. Also, check the adapter box. Laptop adapters often have an LED light that lights up when your adapter is powering your laptop. If this light is off, then your laptop is not receiving any power.
Once you have checked all your adapter’s connectors take a look at the electrical outlet. The problem could simply be that the power socket you’re connected too is no longer working. Change sockets to rule it out.
For laptop DC power adapters check the DC-jack. These adapters must fit snugly. If you have to have your adapter plugged in just the right spot or angle, then your DC-jack may be broken.
Check Your Adapter
A bent cable can be the culprit of a malfunctioning power adapter. Think of this like a garden hose. If you pinch or bend a garden hose while it is running water, the water will not exit the hose. A laptop power adapter works in the same basic way.
Make sure nothing is resting on your power cable such as a book, laptop bag, or anything else that could pinch the adapter cable. If nothing is bending the cable, check the cable itself. The constant bending from storing your adapter could have exposed the wires within the adapter cable. This exposure can cause it to stop functioning properly.

  Which ac adapter can work with my device?

Q: How can I be sure that this item will work with my device?
A: 1. if your original device's part number or model number is in the listing title in our eBay Store, then there's a 99% chance that the item will work with your device. This holds true even if you do not see your device in the listing info/comparability sections.

Q: I see my original device part number in the eBay listing title, but want to make double sure the item will work with my device before I buy.
A: 1. the easiest way is to compare the original device you are replacing with the item specifications of the new device, as shown in the body of the eBay listing. For example, if you are replacing a Sony laptop AC charger, compare the voltage (19.5 V) and current (4.74 A) on your original with what you see in the listing info. Also, check to make sure the AC charger tips match as best as you can tell. Nearly all of our listings contain an image of the charger tip for you to view.

2. If you lost the original and have nothing to compare with, check the web site of the manufacturer of your device/laptop under AC charger specifications. The manual that came with your device is a great source for this information as well. You can also find voltage and amperage info on a label typically located on the bottom of your laptop near the battery (in most cases).

  I am replacing the AC charger for my device and confused about the Voltage and Current specifications?

Q: I am confused about the Voltage and Current specifications?
If you find the required specification of your laptop is not the same as what our adapter provides, please note:
1. The required power (which shown in the back of your original adapter and notebook computer) is the minimum power that will turn on your notebook computer. So in selecting a replacement adapter, the provided power has to be equal or greater than the required power.
(Power (W) = Voltage (V) x Current (A)
Ex. 72 W = 16 V x 4.5 A)
2. When comparing the required voltage and the replacement adapter output voltage, exact number is recommended. But in case of special voltage required by some notebook computer models, ex, 18.5 V or 16.2 V, it is safe to use the voltage that closes to the required voltage, as every electronic device will have positive/negative tolerance of the operating voltage. So 19 V or 18 V will work for the 18.5 V, and 16.2 V can be replaced by 16 V.
3. Most consumers will have the opinion that if the adapter output current is greater than the required current, the device will short circuit. As a matter of fact, only the wrong voltage (which is a voltage much higher than the required voltage) will cause a malfunction or burnout of the device. The current indicated on the replacement of adapter is the maximum current that the adapter able to output, not necessarily the operating current. Actually the operating current is controlled by the device requirement, not the adapter.
If the required input is 19 V / 2.64 A (50 W)
you can use the following replacements:
19 V / 3.16 A (60 W) or 19 V / 3.42 A (65 W) or 19 V / 4.74 A (90 W)
But suggest using 19 V / 3.16 A since it has the closest (but enough) power to run the device.

  Laptop Battery Power Ratings and Power Consumption 101

Power Rating Terms
Every laptop battery is given a power rating in order to show you, the consumer, about how long your battery should last before it needs to be recharged. These electrical specifications are given using volts (V) and milliAmps (mAh). For example, you may see your battery is given a rating of: 10.8V, 4000mAh.
Volts and milliAmp hours are used because they measure the amount of energy used by a laptop battery. A volt (V) is a measurement used for the amount of pressure the positive and negative electrodes produce in a battery during the process of discharging energy. Amps (A) measure the amount of resistance the energy in your battery produces in order to power a laptop.
Think of volts and amps in terms of a shower. When a shower is turned on half way, the water that goes through the pipe produces a certain amount of pressure. When you turn it on to its full amount, the water produces more pressure in the pipe. This pressure, or power, is similar to the volts a battery uses. If a laptop is running simple programs, little power is needed to discharge energy into a laptop. However, if a laptop is running a DVD movie or other high energy consumption applications, more power will be needed to discharge the necessary amount of energy to run the DVD movie.
You may also notice that increasing the size of the pipe and shower head without having to open the faucet all the way will produce similar results. This is an example of the amount of resistance in the flow of energy. Measuring this resistance is measured in terms of amps. In terms of a battery, the amount of resistance is dependant on the size of the battery and the amount of energy inside.
Battery life: A Few Things to Consider
Laptop ratings are given in terms of amp hours (Ah). Amp hours measure the length of time a battery will discharge energy before it needs charging. In order to adequately measure battery life, manufacturers use milliAmp hours (mAh). This means that every 1000mAh is equal to 1Ah. What does this mean for your new battery? If your original battery is measured at 2500mAh and your replacement battery is measured at 5000mAh, then your battery run time will double.
Keep in mind that technology constantly changes. Your old battery may be rated at a lower run time than a newer one because of technological advancements that have produced longer lasting batteries.
Additionally, your battery’s run time depends on the programs you use. Some programs require more energy to run than others. Examples are: the screen (particularly if set at the brigh test setting), hard drives, CD and DVD drives, and wireless network cards. Unfortunately, there is no definite answer to the question, how long exactly will my laptop battery last? The key factor is how and what you use your laptop for.
One way of conserving power is to go to your Power Management settings icon in the Control Panel. You can shut off settings or programs you do not use. Also consider dimming your screen and shutting off your wireless card when you don’t need it.

  How to buy a laptop battery ?

When purchasing a battery for your notebook computer, the first thing a consumer should look for is the reputability of the product at mind. If the product is made by the manufacturer of your laptop (i.e. Sony, Compaq, Dell, etc), you can usually be sure it is a quality product. However, many manufactures do not actually manufacturer, instead they are the brander of the product. For example, if you open up a genuine Sony laptop battery, you may find that the power cells inside are actually made by Toshiba, Panasonic, or a similar big name company. Sony in this case has just made the plastic case of the battery. This goes to show that the brand of the battery you are buying does not necessarily mean that the quality is superior. Many third party brands use the exact same power cells as original manufacturers. Using a third party manufacturer is often a good way to go when buying a battery, as there are usually many extra benefits. For instance, most third party batteries are much lower in price than original manufacturers’ batteries. Secondly, they usually offer a superior warranty, as they realize that in order to win the consumer’s confidence; they must stand behind their product. A one year warranty is a must. Don’t buy any battery with a warranty less than one year. Batteries have been known to die early, and a three month warranty could leave you high and dry.
The next main thing a consumer should look for is the type of battery. Batteries can be made using several chemicals. For laptops, there are four main types. They are Ni-Cad, Ni-MH, Li-Ion, and Li-Poly. There is no major manufacturer that still makes Ni-Cad laptop batteries, as they are a very old and primitive type of power. Ni-MH is newer and more advanced, but is not as good as its Li-Ion and Li-Poly counterparts. If we compare the last three types (Ni-MH, Li-Ion, Li-Poly), we find that Ni-MH batteries weigh more than the other two, but produce less current than the other two. Li-Ion and Li-Poly are the most advanced types of batteries on the market, and you should try to get one of these two types if possible. Most laptops that come with one type of battery can not use any other type of battery, meaning that if your laptop came with a Ni-Cad, it must be replaced by another Ni-Cad. The same goes for the other types. Please note that in some cases, this does not apply. Some laptops that come with a Ni-MH battery can be replaced with a stronger Li-Ion one.
Lastly you must look at the power rating of the item you’re buying. As technology advances, so do power ratings. The battery you bought last year may be twice as strong this year, and might even be the same physical size. Batteries have two main ratings on them: Volts and Amperes. Because laptop batteries do not carry a very large amount of power when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, always go for the battery with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. We will now show you an example of finding the Watt-Hours for our example battery.
Our example battery is 14.4 Volts, 3600mAh
(remember that 3600mAh is equal to 3.6 Amperes).
14.4 x 3.6 = 51.84
This battery has 51.84 Watt-Hours. The term Watt Hour signifies the energy needed to power one watt for one hour. Thus this battery can power 51.84 watts for one hour. Suppose your laptop runs at 25.92 watts (this may be unlikely, but let’s use this just for simplicity). This battery could power your laptop for 2 hours. People usually associate the word ‘Watts’ with light bulbs, and yes, this battery could power a 40 watt light bulb for about an hour and 18 minutes, a 60 watt light bulb for about 52 minutes, or a 100 watt light bulb for 31 minutes; it’s the same idea.
The reason we have shown you watt-hours is because oftentimes the volts and Amperes vary. For example our laptop that uses a Li-Ion 14.4 Volt, 3600mAh battery may use a NI-MH battery that is 9.6 Volts, 4000mAh. Now let’s do the math and find out which battery is stronger.
Li-Ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-Ion is stronger.
Should I get a used battery?
This is a very valid question that every bargain shopper will encounter. Your first option is to purchase a new battery that naturally has new power cells inside. Performance will be at 100%, and it usually comes with a 1 year warranty. However, many companies will either skip that first option by offering only a used or refurbished battery, or they will give you both options: the choice of a new or a used/refurbished. Be skeptical when you see used/refurbished. Usually the warranty on this type of battery is very minimal. Now if you do not use your laptop very much, then this may be a great alternative vs. purchasing a new battery in upwards of $100. Refurbished batteries do not hold as much power when compared to new batteries. Also, they can kick the bucket on you randomly since you really do not know how old the battery is. Our recommendation is to stick with a new battery, or be very careful who you buy your refurbished battery from.

  FAQ’s About Laptop Batteries ?

Q: How long will my laptop battery power my computer for?
A: This is the most famous consumer question, and is the hardest one to answer. This answer depends on the exact laptop model that you have. Some laptops can run for 5 hours or more off of their battery, while others may last less than 2 hours before they need to recharge the battery. Generally, you should contact the manufacturer of the laptop in question, and they should be able to give you an estimate. Remember that the size of the screen, the power of your processor (PIII, P4, etc), your hard drive, and many other things such as the programs you are running (DVD, CD-Burning, Word Processing) will all effect your time away from the wall, making this a very hard question to answer.

Q: What do I do when the power runs out?
A: Recharge the battery. All laptop batteries are rechargeable. To recharge them, simply plug in your AC power adapter. This will charge the battery even while the laptop is still on (you can also turn the laptop off to charge the battery faster). You can literally keep your laptop on all the time, and use it on battery too if you just recharge it when the battery runs low.

Q: What do I need to do to get the most out of my battery?
A: There are several ways of increasing the battery life and getting the most out of your investment. It is recommended to charge your battery up to 100%, each time you charge it. Then, when you use it, do not plug it back in until the power is very low (usually between 5%-15%). Though Li-Ion, Li-Poly, and newer Ni-MH batteries do not require this step, we have found that it does usually help extend the life of the battery.

Q: How do I increase my run time (the length I can use my laptop on battery power)?
A: Run time can be increased or decreased depending on the applications and tasks that you have your laptop doing. For example, if you are playing a DVD movie, much power is being used. If you are burning a CD-R/CD-RW or playing a full screen 3D video game, much power is being used. All these things take more power and in effect lessen the amount of time that you have in “portable” mode. It is best to try to plug the laptop into the wall if possible in these situations. Remember that you can also get car power adapters for your laptop; this will charge your battery and power your laptop while you are on the road. Programs that take little power (giving you longer battery life) include word processing programs like Microsoft Word or Corel Word Perfect, Microsoft Excel, Microsoft Access, Outlook Express, Internet Explorer, AOL, CompuServe, or any similar programs. Even the colors displayed on your screen can affect your battery life. Lighter colors take more power to produce. External connections such as USB Mice, USB Scanners, Memory Cards, Zip Drives, etc. all take more power from your precious battery life. Keep these things in mind when power is of the essence.

Q: The rated voltage of my original battery is 14.4 V or 14.8 V but the rated voltage of your battery of the same model is 10.8 V or 11.1 V. Is it really applicable to the computer of the same model?
A: The safe DC voltage range of a laptop is 5.5 V 24 V, which is evidenced by the power adapter equipped for the computer. The equipped battery or the original battery falls within a safe voltage range required for rated work. As we know, the laptop batteries are lithium batteries which are characterized by: The voltage increases when the battery is charged to full, and decreases when the battery is discharged. For example, the actual effective working voltage range available from a nominal 11.1 V mAH battery is 9 V - 12.6 V. The voltage is about 12.6 V when the battery is charged to full and is about 9V 10V when the battery is discharged. However, 9V - 12.6V is the effective working voltage available from the battery to the computer. With respect to the principles of DC supply design of the computer, the original manufacturer of any computer designs the supply line of the computer mainboard in that way. Therefore, the batteries are interoperable and safe no matter whether the rated voltage of the original battery is 10.8 V, 11.1 V, 14.4 V or 14.8 V.

Q: How do I calculate the power consumed by my computer in an hour?
A: Such data is available from the relevant professional website. Generally, the power consumed by the computer during the running is related to the size of the computer screen, CPU, memory, hard disk and the power saving circuit design of the computer mainboard. Generally the computer screen size is 13.3, 14 and 15, and the power consumed by a standby computer is about 15WH, 18WH and 20WH respectively. Some P4 computers are defective in the power consumption design and generally consume more power. The computers prevalent in the market now are excellent in the power consumption design. The top brand computers are rather excellent in the design of power saving mode, especially SONY, IBM and TOSHIBA.

Q: How long can a new battery drive the computer?
A: It is difficult to determine the operation time of the laptop battery. The actual operation time depends on how much electricity is required by the device. The screen size, hard disk and other accessories may consume extra electricity and shorten the operation time. The total operation time of the battery also depends on the design of the device. Generally, a battery of a standard volume is designed to drive the computer for more than two hours.

Q: I wonder how many hours my new battery can run on the computer.
A: Generally, the service duration of a battery is directly related to the consumption power of the computer. For example, if the computer has a 10.4 screen and a low-consumption CPU, the computer consumes a power of about 10WH-12WH in one hour of normal service. The output power provided by a working battery is: Nominal voltage multiplied with the nominal capacity is the total output power available from the battery. For example, if the battery is 11.1 V and 4400 mAh nominally, the available power output is 48.8 WH, and the battery can run for about four hours on this computer with a 10.4 screen. The power consumed is also related to the running status of the computer. If the computer is used for playing games or DVD, the computer consumes more power in the full-speed running status, and the service duration of the battery is shortened accordingly.

Q: My battery works for three hours initially, but then it cannot be charged further. Is the battery faulty?
A: Operate according to "Calibrate your laptop battery to optimize its performance" described above. If the problem persists, consult the local distributor.

Q: Why does the computer display completion of charging only 10 minutes after start of initial charging the battery?
A: Operate according to "Calibrate your laptop battery to optimize its performance" described above. If the problem persists, consult the local distributor.

Q: The battery volume is displayed as 30% after the battery is initially charged for several hours. Why? How can I charge the battery to 100%?
A: Operate according to "Calibrate your laptop battery to optimize its performance" described above. If the problem persists, consult the local distributor.

Q: My battery makes the computer shut down directly without alerting or changing into the hibernation status. This occurs for several times in a few minutes after the battery is charged to full. Why?
A: Operate according to "Calibrate your laptop battery to optimize its performance" described herein above. If the problem persists, consult the local distributor.

Q: When I put the battery into the computer, the computer shuts down automatically; when I take the battery out, the computer works normally. Why?
A: That indicates the battery is faulty. That occurs rarely and is possibly caused by technical faults arising from short-circuit protection of the battery interface. In this case, contact your distributor to replace the battery.

Q: The battery does not work and the laptop powers off immediately after I disconnect the AC supply when the battery is charged to a certain percentage or even 100%. Why?
A: When this problem occurs, check whether the ambient temperature is too high. If the laptop is used in a high-temperature environment for a long period, the battery will be disconnected for purpose of protection. In this case, in order to prevent accidents, shut down the laptop first, take out the battery, and then reload the battery. Another possibility is that your computer is faulty in the process of charging. In this case, check the computer because the charging circuit of the computer tends to fail in case of charging. In this case, use the original battery instead and check whether the computer works normally. If the problem persists, contact our distributor to replace the battery.

Q: The electricity volume is still displayed as 0% after my battery has been charged for 20 hours; and the computer is powered off immediately after the AC supply is interrupted. Why?
A: First, check whether the battery contacts the laptop properly. Improper contact makes it impossible to charge the battery even if the communication data of the battery is readable. In this case, try to unplug and plug the battery for more times. If you hear a clatter after inserting the battery into the laptop, it is generally regarded as proper contact. Try inserting for more times, and you will know whether the laptop contacts the battery properly. Pay attention to this especially when you use an IBM laptop. If you are sure that the battery contacts the laptop properly but the battery still does not work normally, the battery may be substandard. This problem is caused by two factors: (1) The line board of the battery is damaged or short-circuited; (2) the battery may be incompatible with your laptop, which is a technical problem and needs to be solved by us. Please contact distributor to check the status of the battery.

Q: Is the battery life reduced if the battery is charged before being exhausted?
A: The calculation of the battery life is based on complete cycles of charging and discharging. The life of a lithium battery is generally 300-400 cycles. You do not need to worry whether the battery is charged for a cycle once the AC supply is connected. Only a complete cycle of charging or discharging counts as a cycle when calculate the battery life.

Q: Do I have to remove the battery when I use the AC supply?
A: Generally, the charging of a laptop battery begins only when the electricity volume is lower than 95%. Due to existence of natural consumption, the battery consumption is basically the same no matter whether you remove the battery or not while the computer is working. However, we recommend you not to remove the battery while operating the computer because this prevents the data loss in case of abrupt interruption of the AC supply. If you remove the battery, wrap it into a fresh keeping film and put in a dry and cool place. Remember to perform a complete charging and discharging cycle for the battery every month to prevent the battery from losing activity.

Q: Why is the electricity reduced before the battery is put into use?
A: Due to influence of ambient humidity and non-insulated environment, the battery is consumed naturally. Depending on the newness and quality of the battery, the electricity of the battery is reduced by about 1% in 3-4 days. Therefore, a moderate reduction of electricity is normal.
