The rapid proliferation of notebook computers brings convenience to our life. Laptop manufacturers try their best to meet consumers' demand. The laptops becomes thinner and thinner to reduce the carrying burden. But for the notebook adapter, almost all people will think it is a trouble! Because the weight of an AC adapter is at least more than 500grams. Like my Toshiba PA3468U Laptop AC Adapter, it's around 600g. I often take it to different places, so it's very inconvenient. If you forget to bring it, hard to find a suitable alternative products

As we all know that notebook adapter for laptop is indispensable. For the power supply system for notebook computers are divided in two parts: one is the internal power supply system; the other is the external power supply (adapter). Generally internal notebook power supply system should be no problem; problems came out from the external power supply system, that is, Laptop AC Adapter!
External power supply has these problems, such as the adapter out of supply, short circuit, automatic shutdown, black screen, even an explosion, firing motherboard. As the adapter is composed by capacitors, resistors, inductors, switch diodes, power-core chips. All these are high-heating element! Therefore, the laptop adapter is really important just under the domain of CPU board, and the LCD screen.
Laptop power adapter looks homely but have many potential drawbacks. We have to pay more attention in the practical application of attention. In order to enjoy the convenience, we should minimize unnecessary payout.
Recently found a piece of adapter in the market which is the world's most compact laptop adapter, weighs only 160g and 1.65cm thick, Compared with my Toshiba PA3468U Laptop AC Adapter,it's really fashion, elegant and tiny.Thus I have no confidence of this product. And it needs time to prove it's efficiency and quality.
In near future, hope my AC Adapter is fashionable.
Have a clear understanding of the battery parameters, do not just care about the cell
Laptop is different from desktop in power supply that is the battery. Then people can go outside and carry their laptop because of the battery. In this case, battery has become challenge to pick. But as a consumer, the most intuitive is that the number of cell batteries. Most of the notebook computer market standards are 8-cell, 6-cell or 4-cell of the lithium-ion battery. One standard 4-cell lithium-ion batteries are often ultra-thin products, but most of these products can choose to have more cell number to stretch battery's life. As for the number of two different laptop batteries, the more cells, the longer batteries keep.Battery Laptop Battery
There are other fans have a better understanding of the laptop, they are more focused on the battery "mAh". "mAh" is the battery capacity. Generally, many of my friends might think that a large mAh battery will have a longer life time. But the reality is not so, the laptop battery can often see "6-cell 4400mAh", "4 cell 2200mAh" battery. Usually we take for granted that the 4400mah is better than 2200mAh.
But in fact that's not not the case, a unit of battery capacity should be considered "Wh"(watts/ hours). Of course, "Wh" and the "mAh" have close relationship with the following formula: Wh ÷ V × 1000 = mAh be noted that the measurement of electrical power consumption of the unit itself should be a power, that is, "Watt."
Since then, we can learn to select the laptop battery should be noted that the place is not the "mAh" but "Wh" and the voltage of a few. For example SONY VAIO VGP-BPS2A Laptop Battery, it's 6-cell and 4400 mAh. Under the voltage of 10.8V and 11.1V they have different abilty that is measured by and "Wh". By calculating we can see which is better.
It is obvious to see that 4400mAh 11.1V Li-ion battery is superior. Next time you can make your mind to buy a suitable battery.
