Adapter Connector Types

Posted by admin on December 25th, 2014

When looking for a replacement laptop adapter, check that the connector is going to fit the laptop’s power port. All laptops use DC power connectors, but not all connectors are going to be the same.

Laptop Connector Types

Description

Cylindrical Connectors Known as barrel connectors, sleeve connectors, tip connectors, and coaxial power connectors; they are an insulated, hollow cylinder that connects to the laptop power port
Snap and Lock Connector Also known as Kycon 3-pin and 4-pin DC power plugs; this connector has three or four pins surrounded by a thin, metal cylinder
Molex Connector Often used on personal computers to supply power; several insulated electrical wires are encased by a flat, plastic rectangular case with 3, 4, or 6 terminals
USB connector Consists of a hollow, rectangular metal tip, inside of which are two or more flat metal pins

Some name brand companies will have their own specialized connector tips for their laptop adapters.Acer Aspire 1810T AC Adapter.This can make the search for an affordable adapter more difficult, but not impossible. The cylindrical connector is the most common type of connector used in laptops. Laptops and electronic devices may also commonly use USB plugs for their power ports. Several types of USB connectors are in use including, Type A, Type B, Mini A, Mini B, Micro A, and Micro B.

AC Adapters and Power Supply

Posted by admin on December 11th, 2014

The AC adapter is an integral part of any laptop. While laptops are able to run on battery power, without the AC adapter, there would be no way to recharge the battery. Laptop AC adapters provide power to the laptop and the battery by converting the electricity coming from an outlet, which is AC (alternating current), into DC (direct current) power and outputting it at the correct voltage. Older laptops often had the convertor or transformer included in the laptop itself, but this added unnecessary weight.

The Acer Aspire One D257 laptop AC power adapter usually has two main parts. The first is the “brick” or the largest part of the adapter, which is the transformer that does the conversion from AC to DC current and connects to the laptop through a cable. Manufacturers specifically differentiate the tip sizes of this cable to ensure that users don’t plug an incompatible adapter into the wrong laptop, which could cause damage to the laptop or laptop AC adapter. The transformer is often significantly larger for more powerful laptops. This is due to the fact that a more powerful laptop requires more wattage. For example, a small netbook, designed for power efficiency and better battery life, may only draw a maximum of 40W of power. A desktop replacement laptop, with more power-hungry components, may draw 185W or more during heavy use. Therefore, it also usually requires a more powerful transformer, which translates to a larger “brick”.

The second part of the Acer laptop power adapter is the power cord, which connects from the brick to the wall outlet and delivers electrical power to the transformer. The power cord normally comes in a couple different varieties depending on the specifications of the AC adapter. With some laptop AC adapters, this cord is permanently attached instead of being removable.

When shopping for a replacement for your laptop AC adapter, it is important to find one that is compatible with your specific model. Use a parts locator tool online to find the laptop AC adapters that are compatible with your model. This ensures that they provide the correct voltage, and that they have the correct tip to be used with your laptop or notebook. As mentioned, using an incorrect laptop or notebook AC adapter could cause damage.

The main choice to make when buying a replacement Acer Aspire One D257 laptop AC adapter is whether to buy an OEM model, which is one made directly by the manufacturer, or a third-party compatible model. Buying a third-party adapter from a trusted reseller can often save money, and many reputable sellers offer a warranty and a satisfaction guaranteed, which will give you the peace of mind that your replacement AC adapter is a quality product.

Types of Adapters for Laptops

Posted by admin on December 3rd, 2014

Laptops rely on two main types of power adapters for energy: the AC adapter and the DC Adapter. These adapters, also known as chargers, are what help convert the electricity from the wall outlet into a form that’s usable for the laptop.
AC Adapter
The Acer LC.ADT0A.023 AC adapter converts AC power from a wall outlet found in most homes to the DC power used by most small appliances. Laptops, cell phones, computers, and DVD players all use DC power. This is the kind of power provided by batteries, which most laptops use to keep running when the owner is mobile.
DC Adapter
Laptops use DC power, so it doesn’t seem like a DC adapter is necessary when plugging into a DC power source. However, most sources of DC power provide a voltage that is too low for the needs of a laptop. A DC power adapter is required to take that power and convert it to a higher voltage that the laptop can use to charge its battery or run. DC power sources include cars, in-flight outlets, and solar power panels or batteries.
Universal Power Adapters
Another option for laptop owners is a universal power adapter. These adapters are more expensive, but can adapt to any power source and voltage. Theoretically, universal adapters can work on any Acer laptop. This makes them quite useful, especially among those who travel frequently and never know where their next source of power is coming from. Universal adapters also come with a variety of connector types to fit a wide range of laptops. Many laptops use different styles of connectors so it can be hard to find the best adapter to fit.
