Not All Laptops Charge At The Same Speeds

Whats Inside Laptop power adapter//basic working principle & fault

Its not just about how powerful the wall adapter is. A lot of it has to do with how much power the laptop can take as well. Different laptops support different power inputs. The newest MacBook Pros support a max power input of 96 watts, for instance, while the newest MacBook Airs are significantly less than that. This means that not every USB-C laptop will be able to charge at the same speeds, no matter how powerful the chargers power output.

The other thing is that not all USB-C ports are the same. Specifically, not all USB-C ports support Power Delivery and not all of them accept charging. Also, not every USB-C cable supports PD. So if youre wondering why your laptop isnt charging even when plugged in, it could be an issue with the charging port or the charging cable youre using.

The USB-C connector looks similar to a micro USB connector at first glance, though its more oval in shape and slightly thicker to accommodate its best feature: flippability. Like Lightning and MagSafe, the USB-C connector has no up or down orientation. Most of the time, you have different connectors at each end.

Keep Your Power Cord Away From Water

Water and electronic devices don’t mix, so it’s essential to avoid situations where your laptop power cord could be accidentally exposed to water as this can cause electrocution, damage to your laptop, or both. This means not charging your laptop in or near your kitchen or bathroom.

If your laptop charger comes into contact with water, disconnect it from the outlet at once and move it away. Thoroughly dry the charger and make sure it is completely dry before deciding whether to use it again.

Why Is My Laptop Charger Turning Yellow

Inside laptop adapter

Some chargers will change color because their owners always handle the cords with oily and greasy hands. Additionally, If the charger spends a lot of time in the vicinity of devices that generate a lot of heat, the outer insulation will start losing its elasticity. Besides deforming and tearing open, it could also turn yellow.

In some cases, the yellow discoloration is a sign of aging. The color can also appear as a result of sunlight exposure. If your cable is exposed to the sun every single day. it is going to age at a much faster rate.

You may see this phenomenon in cheaper cables. They are made of inferior material that will degrade at a much faster rate. The form that degradation will take may vary depending on the material and how you treat the charger.

If you always handle the cords with oily and greasy hands, chargers will change their color. But the transformation takes a while.

This also applies to people that handle inferior chargers with latex gloves. Besides causing various chemical reactions, the use of latex gloves may cause the jacketing of inferior charger cables to wear off.

If you dont use latex gloves, and the charger is rarely exposed to oil, grease, or even sweat, consider the temperature.

Chargers have a limited lifespan regardless of the brand or quality. They are going to age over time. The more time you spend handling them, the faster they will age.

Heat can accelerate the aging process as well which could also turn the charger yellow.

What Is The Difference Between A Converter And A Power Transformer

Converters and transformers are both used to change one voltage to another, but this ambiguity can cause confusion as their purposes are different:

  • Power converters are designed for simple electrical appliances which typically generate heat or use motors such as clothes irons, shavers or hair dryers. Transformers are designed for more complex electronic items such as televisions or games consoles.
  • Buying a power converter is cheaper than buying a power transformer.
  • Power transformers are larger and heavier making them more suited for permanent residential use for example an expat wishing to use an imported television would need to use a transformer for this purpose.
  • Power converters are more suitable for travellers wishing to bring domestic appliances abroad such as hair dryers or flat irons. However, it is more practical and cost effective to purchase a dual voltage appliance designed for travel rather than a heavier power converter.
  • Power converters are suitable for 2 pin ungrounded appliances, it could be harder to find a converter if you want to use a grounded 3 pin appliance.
  • Transformers can be used constantly however it is recommended that converters are used for no longer than a couple of hours at a time.
  • Shops may sell transformers under the name of converters, for the purposes this guide we will be referring to both converters and transformers as converters.

How Long Do Rechargeable Batteries Last

Not surprisingly, it depends on how you treat them, store them, and use them.Small rechargeables typically last hundreds of “cycles”, which can mean anything from several yearsof decent life in a laptop to a decade of use in a portable radio. Treated well,lead-acid car batteries are usually good for thousands of cycles and can easily last510 years in a car that’s driven each day. But if you leave rechargeable batteriesin a product you barely ever use, never charge or discharge them, overcharge them,let them overheat, or store them in poor conditions, don’t expect them to last long.

How do you know when it’s time to replace batteries? In something like a laptop, you mightnotice a lithium-ion battery discharges normally for a time, then suddenly loses all its remainingcharge very quickly. If you’re using rechargeable NiCd or NIMH batteries in things like flashlights,you’ll see very gradually reducing capacity and the need to recharge much more often.

Belker 65w Universal Laptop Charger

The Belker 65W Universal Laptop Charger is similar to the ZOZO in terms of basic design. Theres an AC power cord, a power supply block, and a DC cord running out of the power supply. The only significant difference is the length of the cord, which measures 6 feet instead of 10 feet. For what its worth, the LED is also blue instead of green. But lets be honest, one laptop charger looks the same as another.

The similarities even extend to the number of tips. These include 16 different options, for a variety of brands. Among others, you can find tips for Acer, Asus, Compaq, Dell, HP, IBM, Lenovo, and Sony laptops. Youll also find that all the tips attach with the same standard three-pin connector.

Power Input and Output

The Belker charger can accept an input power of between 100 and 240 volts, and from 50 to 60 Hz. This makes it suitable with both US and international power outlets. As with the ZOZO, youll still need a plug adapter of the appropriate socket type for the country youre in.

Output voltage is more limited than the ZOZO. There are 18.5, 19, 19.5, and 20-volt tips, with a maximum power delivery of 65 watts. As a result, youll be limited to powering small to mid-sized laptops. On the other hand, there are still 16 tips. This gives you broader coverage among this size of machine. You also get overload and over-voltage protection to keep your charger and laptop safe.

How Much Power Do I Need To Charge My Laptop

The easiest way to find out how much power is required to charge your laptop is to inspect the charger that was sold with it, if you have that to hand. Alternatively you can look for its specification on the manufacturer’s website.

You’re looking for a figure in Watts, although it may be expressed in Volts and Amps. If so, simply multiply these two numbers to get the figure you need. For example, a laptop that requires 12V/2A to charge will need a 24W USB-C PD charger .

Once you know what power rating you’re looking for, finding a USB-C PD charger for your laptop or console is easy. Sometimes it can pay to get one a little faster than you need – it may be more expensive, but you’ll be pleased you bought it if you later decide to upgrade your laptop.

Look out for newer GaN chargers that require fewer components than traditional silicone chargers, allowing them to be less bulky and also more efficient.

Power Delivery Is Required To Charge A Modern Laptop Or Console Over Usb

By, Editor In Chief| 15 Dec 2021

If you’re wondering why your laptop will happily charge from some USB plugs but not others, the answer is USB-C Power Delivery. We’ve rounded up some great examples you can buy right now.

It’s not quite as simple as searching for a charger with Power Delivery support, however. While some laptops will charge from a 30W adaptor, others require significantly more power. These chargers range in output – as of May 2021, up to 240W! – so to find a compatible device you really need to know what is required by your particular model of laptop.

If you’re looking to fast-charge a smartphone that promises charging of, say, 65W, do note that many third-party Power Delivery chargers will not support protocols such as PPS or SCP that is required by proprietary fast-charging standards. You can expect 18W charging from such devices, regardless of the theoretical output of the USB-C port.

What Does Yellow Tip On Charger Mean

inside a cheap and very shitty USB battery charger.

The laptop charger yellow tip is an aesthetic choice designed to set the charger apart. The yellow tip of a coaxial power connector is supposed to show the manufacturers adherence to EIAJ standards. It also points to the chargers specific operating voltage range. Some manufacturers offer interchangeable color-coded tips.

But you also have instances where the yellow tip is supposed to specify a particular attribute.

You have to read the manual to find out what the yellow tip means because chargers do not have a particular standard that manufacturers have to follow, at least not where the look and design of the tips are concerned.

The field tends to determine the meaning of the yellow tip.

Only your laptops manufacturer can tell you what the colors mean. If the manual doesnt say anything, the yellow tip is just a piece of plastic. It doesnt mean anything and it wont affect your chargers operations.

It should be noted that the laptop charger yellow tip is easier to dismiss as unimportant if it was yellow in the first place. If the tip started as a different color and it became yellow later on, you should contact a technician.

What Is A Usb

Have you ever looked closely at the USB symbol? Chances are high that youve come across the simple logo: a trident with prongs that end in a square, circle, and triangle. Its thought that the three shapes signify the many devices that can be supported by a USB connection.

The first rectangular USB-A port solved a major problem by helping us link up all our peripherals with a common connector. These days the slim oval USB-C shape is fast becoming the universal standard because it offers faster data, power, and video transfer in a smaller package.

Yet, USB-Cs extra abilities have actually created a new problem for consumers. The manufacturers of those peripheral devices can deploy different underlying technologies inside the USB-C shape. So now, the multiple gadgets represented by the square, circle, and triangle in the USB symbol might have USB-C connectors that are built to do different things. Some USB-C connections will charge host devices, support video, support the mighty Thunderbolt3 technology, or only support data. If youre confused, dont worrythere are ways of figuring out what kind of technology lies within a USB-C connector. Kensington is here to demystify USB-C by explaining its features and teaching you how to read the various USB symbols.

Can I Use A Lower Wattage Charger For My Laptop

The answer is yes. You definitely can use a lower wattage charger for your laptop , but this will directly impact the performance of your laptop itself. For instance, using a 45 watt charger for a laptop that requires 90 watts might not enable it to function at its maximum potential. Again, this greatly depends on the type of activity being carried out on your laptop itself.

For instance, if youre using your laptop to read some article, or if your laptop stays idle with minimal brightness level, the low wattage charger will work perfectly fine. But if you plan on watching a video or a movie at high volume, it is highly likely that your laptop rejects the power coming in through the charger, and switches over to the DC power stored in its battery. Since the laptop will not be gaining any power through the low wattage charger, it will ultimately shut down once the battery runs out.

Using a low wattage charger for your laptop will be more of a frustration, rather than a convenience to you. Based on multiple reviews and experiences by users, as well as professionals, it can become quite difficult to properly charge your laptop through a low wattage charger. Since the power trickles in slowly, it might take hours to fully charge your laptop, which is definitely not an ideal situation if youre in a hurry.

Are You Plugged In

Charging a Macbook with an external battery via USB-C

It sounds silly, but you need to make sure the laptop is actually plugged in. This is a major reason a computer may not even start. No software tweak or hardware repair can make a disconnected laptop magically power on. So before you do anything else, ensure that the AC outlet and laptop plugs are firmly seated.

Check the AC adapter brick and verify that any removable cords are fully inserted. Next, make sure the battery is properly seated in its compartment, and that there is nothing wrong with either the battery or laptop contact points.

Finally, find out whether or not the problem even has anything to do with the laptop at all. Try plugging the power cord into a different outlet to see if you’ve got a short or a blown fuse. If it’s plugged into a surge protector or power strip, take it out and plug it directly into the wall.

At this point, if it still doesnt work, we’ve determined that it’s not just user error causing the problem. There is a real issue with powering the laptop now it’s simply a matter of figuring out where the problem may be. That begins with eliminating where it isn’t. We’ll start with the most common and easy-to-address issues.
