The fact is that they are based on a conductor such as silicon. Its use, firstly, requires the use of a larger number of components in the design of the power adapter, and, secondly, it makes the adapter itself less energy efficient, which is why the associated energy losses are greater than that of analogs.

Why are charging bricks so big?
The more power your gadget draws, the larger these spools of wire need to be to convert correctly. This is why a phone charger is so much smaller than a laptop charger, and why the charger for an Xbox is even larger than that. In addition, the conversion process wastes electricity, which turns into heat.
Why are laptop chargers so large?
As for why the laptop converter is generally so much larger than the usb chargers for cell phones/tablets/etc.Due to the higher voltage & current demandex by the laptop, its power supply needs thicker wires, a larger inductor, and higher-power switching components.
Why are laptop power bricks so big?
It’s not unheard of for a laptop review to ding the product for a surprising reason: A bulky power adapter.This is because modern power converters repeatedly deliver small packets of energy to the electronic device in cycles called switching cycles.
Is there a smaller MacBook charger?
Belkin has announced a new 60W GaN charger. It features a single USB-C plug and can charge a MacBook Pro. The size, however, comes in around the same as the current iPhone charger.
Are laptop chargers Transformers?
Actually, neither laptops or cell phones use a transformer, per se. What they use, instead, is called a “Switched-Mode Power Supply” that rectifies the 110 or 220V AC input into a DC capacitor, then uses a multi-KHz switching microcontroller to pulse that through an inductor to “convert” the voltage down.
Why do laptop chargers have two parts?
Laptop chargers have two parts: a transformer and a power cord. The transformer is the brick that converts the current from your power outlet from AC to DC, and the power cord connects the charger to the outlet. Over time, transformers can overheat, which can cause internal damage.
Why do gaming laptops have big chargers?
Gaming laptops have powerful graphics processing cards which require a lot of power to run. Hense the power adapters are huge to accommodate the power requirement. Because they need more power.
Why do laptop chargers have bricks?
The brick is part of the external power supply and also provides the power for the laptop to charge its batteries. Plugging straight AC from a wall outlet into a laptop would blow the circuits because laptops run on low DC voltage, so they need to convert AC to DC. The brick accomplishes this conversion.
Why do laptop chargers have a box?
Your laptop and its battery can’t use the full amount of electricity provided by a regular household or office outlet, which produces 120 volts of alternating current. Inside the adapter’s “line lump,” a stepdown transformer reduces the strength of the current to a level the system can use.
Why do chargers need transformers?
A transformer is used to increase or decrease the AC voltage depending on the turns ratio in their primary and secondary coil. Now the mobile phone battery produces DC voltage and can only be charged by providing exact amount of DC voltage specified for it.
Can you charge a laptop without a transformer?
Yes, and the easiest way to do it is with a universal adapter. Remember to always check the voltage, no matter the charging solution. If that doesn’t suit you, charge your laptop from a car battery or use an external battery charger.
What is the fastest MacBook charger?
The Apple 30W USB‑C Power Adapter offers fast, efficient charging at home, in the office, or on the go. While the power adapter is compatible with any USB‑C–enabled device, Apple recommends pairing it with the 13-inch MacBook Air with Retina display for optimal charging performance.
Is OWC trustworthy?
OWC/macsales.com is a very legit company, I’ve used them many times over the years to buy RAM. In fact, every Mac I’ve ever had has had additional memory installed that was bought from these guys. They also have good deals often on external FW disks.
Does Apple replace MacBook Chargers?
Yes. Apple will replace chargers for up to one year, but not ones that are fraying or show signs of wear – at least not for everyone, that is.
Should my laptop charger make noise?
A “hum” or “whine” is relatively normal, and likely an innocent by-product of the transformer using electromagnetic plates to convert current. A “crackle” or “sparking” noise is potentially a sign of a failing transformer, and a potential fire hazard.
What is the block called on a charger?
That BOX might be called as power outlet or power socket in which you plug into a charger.
What is a laptop charger called?
A power supply for electronic devices. Also called an “AC adapter” or “charger,” power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.
Can a faulty charger damage my laptop?
Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won’t damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.
How can I spoil my laptop charger?
Avoid letting the AC adapter hang in midair; this will put stress on the plug that goes into your laptop. Over time, this will weaken the plug and could even damage the socket, preventing you from charging your computer. Having a bit of slack in your cables is important.
Why do my laptop chargers keep breaking?
If your laptop charger seems broken, it’s most likely because the battery will not charge. You plug in the cord, the lights come on, but the charging light doesn’t change or blinks repeatedly. When you remove the power cord, the laptop shuts off instantly due to the depleted battery.
