So, how long do laptop chargers last? Generally speaking, laptop chargers can last around 3–5 years.

However, this can vary depending on the make and model of your laptop, the quality of the charger, how often you use it, and how you take care of it. If you use your laptop regularly, you may find that your charger starts to wear out sooner than expected.

Laptop Charger overview

Laptop chargers, also known as AC adapters, are devices that provide power to laptops by

converting AC (alternating current) electricity from a wall outlet or other power source into DC (direct current) electricity that can be used by the laptop’s battery.

Here’s how laptop chargers typically work:

  1. The charger has a transformer that converts the incoming AC voltage to a lower voltage that is suitable for use with the laptop.
  2. The transformer is followed by a rectifier, which converts the AC voltage into DC voltage.
  3. The DC voltage is then filtered by capacitors, which smooth out any fluctuations in the voltage and help to regulate the power supply.
  4. The charger also has a voltage regulator, which ensures that the voltage supplied to the laptop is stable and consistent.
  5. The charger is connected to the laptop via a power cord and plug, and the charger’s output is connected to the laptop’s battery via a DC jack.
  6. When the laptop is plugged in and charging, the charger sends a constant stream of DC power to the battery, which charges the battery and powers the laptop at the same time.

Overall, laptop chargers are fairly simple devices that play a critical role in keeping laptops powered and ready for use.

How Long Do Laptop Chargers Last?

A laptop charger typically has a lifespan of about 3–5 years. This may vary depending on the make and model of your laptop, as well as how often you charge it.

But that doesn’t mean you have to replace your laptop charger every 3 years. Many people find that by using a quality charger and taking care of it properly, they can extend the life of their charger by up to four years.

Be careful with your charger. Bending or twisting the cord can damage it and shorten its lifespan. Similarly, avoid exposing it to extreme temperatures, whether hot or cold. This can also damage the cord.

The Average Life Span of Laptop Chargers

The average lifespan of laptop charger is around three to five years. However, this can vary depending on the make and model of the charger, as well as how often it is used. For example, a charger that is used only occasionally may last longer than one that is used regularly.

Additionally, some laptop chargers are designed to be more durable than others, so they may last longer as well.

To extend the life of your laptop charger, it is important to carefully follow the instructions that come with it. For instance, you should avoid using the charger in humid or dusty environments, as this can shorten its lifespan.

Again, you should always store the charger in a cool, dry place when not in use. If you take care of your laptop charger, it should last you for several years.


How long do Apple laptop chargers last?

The lifespan of an Apple laptop charger is around three to five years. However, this is only an estimate, and the charger could last longer or shorter depending on how often it is used and how it is taken care of.

If the charger is used daily and taken care of properly, it could last up to five years. However, if it is used infrequently or not taken care of properly, it may only last for three years.

Apple laptop chargers are known to last for a longer period of time than most other laptop chargers. In fact, many people have reported that their Apple laptop charger has lasted for up to 10 years.

Although the lifespan of an Apple laptop charger is only an estimate, it is important to note that chargers can and do degrade over time. Even if a charger is only used infrequently, it is still important to check it for signs of wear and tear. If a charger begins to show signs of wear and tear, it is important to replace it as soon as possible to avoid damaging the laptop.

Factor That Affect 

How Long a Laptop Charger Last

So what exactly affects the lifespan of a laptop charger? Here are five major factors:

UsageHow often you use your laptop charger will have an impact on its longevity. For example, if you’re using your laptop all day, every day, and charging it up, then your charger is likely to wear out sooner than expected.

Quality: The quality of your charger matters too. A low-quality charger is more prone to overcharging and can get easily damaged from regular use. Invest in a good-quality charger, even if it’s a bit more expensive. It’s worth it in the long run!

 Heat: The heat generated when you use the laptop can damage its charger as well as the laptop itself. Make sure you don’t leave it plugged in for too long and keep your laptop away from extreme temperatures, such as near direct sunlight or on top of heating elements.

Voltage fluctuation: Power surges or voltage fluctuations can also shorten the life of your laptop’s charger. Make sure that you’re using a surge protector so that none of these occur and to keep the power supply stable.

Aging: The aging of the components inside all electronics makes them susceptible to shortening lifespans over time, regardless of usage or environmental factors.


How long do laptop power adapters last?

How long do laptop power adapters last? This is a difficult question to answer, as it depends on a number of factors. The quality of the adapter, how often it is used, and how well it is cared for can all affect its lifespan. In general, however, most laptop power adapters will last for about 5 years with proper care.

To extend the life of your laptop power adapter, be sure to keep it clean and free of debris. Be careful not to bend or damage the cord, as this can cause problems down the line. And always store the adapter in a cool, dry place when not in use. With proper care, your laptop power adapter should last for many years.

Do laptop chargers wear out?

Yes, laptop chargers do tend to wear out over time. This is due to a number of factors, such as the number of times you plug and unplug the charger, temperature, power surges, and dropping it accidentally.

Keeping your laptop charger in a well-ventilated area can help prevent overheating, which can damage the power adapter over time.

Power surges, on the other hand, can cause immediate damage to your device, so be sure to unplug everything when storms roll in.

And dropping your laptop charger—let’s just say that should be avoided at all costs!

Again, laptop chargers contain a large number of small parts that can, over time, become worn down by friction and heat.

This is why it’s important to avoid over-bending or tangling up the wires and cords that come with your charger.
It’s also smart to make sure to unplug your charger after each use, as leaving it plugged in can cause extra wear and tear on both the charger and your laptop.

When should I replace my charger?

When it comes to replacing your laptop charger, the general rule of thumb is that you should replace it when you start to experience problems with it.

This could mean anything from an overheating charger to a charger that is no longer able to deliver enough power for your laptop.

It’s also important to note that if you’re using a lower-quality charger, it may need to be replaced more often than a high-quality one.

That’s why I always recommend investing in a good quality laptop charger; they may cost more initially, but they will last much longer and be better for your laptop in the long run.


How do I know if my laptop charger is bad?

If you think your laptop charger might be bad, there are a few ways to check and make sure.

One easy way is just to look at it—if the cord or plug is torn or frayed, it’s probably time to replace it.

Another way is to check the charging port on your laptop; if you see any discoloration or burnt residue, that could be an indication that the charger isn’t functioning correctly.

Lastly, if your laptop isn’t charging or you’re often getting the “plugged in, not charging” message, then it’s also a good sign that your charger might be bad.

If any of these signs are present and your laptop charger is still under warranty, then it’s best to get a replacement from the manufacturer for free.

But if the warranty has expired, then you have to purchase a new one yourself.

How to make laptop chargers last longer

If you want your laptop charger to last longer, there are some simple steps you can take to ensure that it does. Here are 7 tips for making your laptop charger last longer:

1. Unplug for long periods of time. Unplugging your laptops charger for long periods of time can help prevent the wires from becoming frayed or damaged due to constant use. This will help lengthen its life.

2. Use the correct wattage. Using the correct wattage for the laptop model is important to make sure it has enough power without overload or stress.

3. Keep away from heat: Heat causes the components of a charger to deteriorate over time, so keep it away from hot surfaces if possible.

4. Clean keyboard and mouse parts: Periodically cleaning dust, lint, and dirt off of the keyboard and mouse can help optimize performance and extend the life of your laptop charger.

5. Keep liquids away from your laptop charger. Avoid getting any liquids on your laptop charger, as this could damage its components if it seeps inside.

6. Avoid bending or twisting wires. Bending or twisting wires can cause short circuits, leading to a loss of power or even complete failure in some cases.

7: Store in a padded bag: If you’re not using your charger, keep it in a padded bag so that it won’t get knocked around and damaged by other objects.

Can I leave my laptop plugged in 24/ 7?

Yes, you can leave your laptop plugged in 24/7. This won’t hurt your battery since it’s trickle charging (slowly topping off the battery’s charge). However, even though you can leave it plugged in, you shouldn’t.

Here’s why: Even though laptops these days are designed to be used while they’re plugged in, they still discharge a tiny bit while they’re plugged in.

Leaving your laptop plugged in when it’s fully charged, like your smartphone, is bad for the battery in the long run. Over time, this type of “topping off” lowers the capacity of the battery, which means it won’t hold a charge for as long.

So even though you can leave your laptop plugged in 24/7, you shouldn’t. Unplug it when it reaches 100 percent to prolong your battery’s lifespan.

How can I test my laptop charger?

Wondering if your laptop charger is still working as it should? Good news: there’s a way to test it! All you need is an ohmmeter or multimeter, which you can easily find online or at your local hardware store.

To begin, switch your meter to the lowest resistance setting and use the probes on the plug tip of the laptop charger to measure its resistance.

That will allow you to determine whether or not the pins are making contact. If they are, then you should get readings of anywhere between 0.9 and 1.1 ohm.

This means that the laptop charger has no major issues and is most likely working properly.

On the other hand, if you get a reading higher than 1.1 ohm, then there may be some problems with your charger, such as corrosion or broken wires.

You can also check for any signs of physical damage to the power cord itself, like frayed edges or exposed wiring. If either of these conditions exists, it’s time for a new charger!


So, how long do laptops chargers last? In short, it really depends on how often you use your laptop and what type of charger you have.

If you use your laptop regularly, then you can expect your charger to last around three to five years.

However, if you only use your laptop occasionally, your charger could last much longer.
