Impartial Comparison between Pros and Cons of Laptop AC Adapter
It's never exaggerated to say that AC adapter is the most important accessory for laptops saving for laptop battery. Because of the convenience and portability, laptop AC adapter is touting by travelers, businessmen and business women, and even it's the hot for everyone who is using laptops. Consequently, maintain and preservation of laptop AC adapter has already opened a big potential market. If you are a youth like me and longing to dig your first social golden like me, the following general knowledge about pros and cons of laptop AC adapter can lay a solid base for your future successful business.
Advantages first
AC adapters are widely used to power laptops and other portable electronic devices, because of a number of advantages:
Safety — External power adapters can free product designers from worrying about some safety issues. The designer builds a product to run off a low voltage (usually supplied through a coaxial power connector) and does not have to worry about hazardous voltages inside the product enclosure. Nevertheless, care must be taken if more than a few watts are supplied to a product, even at low voltages, since a malfunction could still start a fire. Thus, an internal fuse, circuit breaker, or thermal limiter may be useful in a powered product, even when a safety-certified external power supply is used. An external, removable AC adapter can also be used to help a design meet the more stringent requirements of intrinsic safety.
Heat reduction — Heat reduces reliability and longevity of electronic components, and can cause sensitive circuits to drift or malfunction. A separately-enclosed power supply moves what is often the primary source of heat to a cable-length distance.
Electrical noise reduction — Because radiated electrical noise falls off with the inverse square of the distance, it is advantageous to convert potentially-noisy AC line power or automotive power to "clean", filtered DC in an external adapter, at a safe distance from noise-sensitive circuitry.
Weight reduction — when most power adapters were simple transformer-based designs, they were quite heavy, and would have added considerably to the weight of portable or hand-held devices. Even modern light-weight switching circuits for AC line power still would add appreciable weight to hand-held devices, whose design weight budget is often denominated in grams. Moving these heavy power-handling components to a separate power supply reduces the dead weight of parts that are only in use during a battery charging cycle.
Size reduction — the physical bulk of line-voltage-rated power supply components and connectors can be shed from portable or handheld devices, slimming them considerably.
Ease of replacement — Power supplies are prone to failure, due to their exposure to power spikes and their internal generation of waste heat. External power supplies exemplify the design principle of modularity, in that they can be easily unplugged and replaced if they should fail.
Configuration versatility — Externally-powered electronic products can be used with different power sources as needed, take HP 496813-001 AC Adapter (http://www.hootoo.com/30w-hp-496813001-ac-adapter-19v-158a-4017-2prong-us-version-p-66007.html )for instance, whose available input volts are AC100-240V 50-60Hz, for convenient use in the field, or when traveling.
Simplified product inventory and distribution — an electronic product that is sold and used internationally must be powered from a wide range of power sources, and must meet product safety regulations in many jurisdictions. The configuration modularity enabled by a separate, external power supply and/or power cord allow satisfying these diverse power requirements with a small number of product stock-keeping units, reducing product inventory costs and overhead costs of warehousing and distribution.
One cut has two sides; of course our convenient laptop AC adapter has problems to solve.
Whilst useful for many purposes, some external AC adapters have attracted criticism. Problems with this type of power supply may include:
Size — the power supply may obscure other power sockets; some power strips attempt to relieve this problem by varying the spacing between their sockets.
Weight — Some AC adapters can be heavy, exerting excess weight on the plug socket (this depends on the socket design of the country in question). Some external power supplies are "power bricks" having a short AC cord so they can lie on the floor, thus relieving strain, at the expense of clutter. Other wall-hanging types are made long and thin, minimizing the leverage of their weight vector that pulls the plug out, at the expense of exacerbating the size problem. Heavy adapters are a burden on travelers, especially if several different ones must be carried for different equipment.
Inefficiency — Some AC adapters, especially older linear power supplies, waste significant electrical energy while in use, or even when the powered device is not in use or disconnected.
Confusion — some consumers are unable to choose or obtain a suitable replacement AC adapter for a given small appliance. This can result in the large scale discarding of "orphaned" adapters and equipment which have been separated from each other. Here I would like to put forward Hootoo.com to you who is the professional B2C website to provide computer accessories and laptop peripherals to retail customers with high quality items at most favorable price. Do not take for my words until you see it in hootoo.com. Such as Brand new PA3467U-1ACA laptop AC adapter (http://www.hootoo.com/pa3467u1aca-c-248_211_249.html )lists at Hootoo, which is sold as low as 13.99$?! Partially many incompatible adapters can be overwhelming, especially in the absence of clear labeling. Still worse, mismatching of adapters can cause severe equipment damage, or even fire.
Compared the disadvantages with advantages of laptop AC adapter, it's self-obvious that laptop AC adapter is the lucrative stock for us to invest. But the final decision lays in your hand.
