  Power adapter working parameters

  With the increasing variety of power adapters, there are more and more manufacturers nowadays. As long as the product quality is guaranteed and the working parameters and output connectors are the same as the original ones, then different brands of power adapters can actually be used universally, and they are also suitable for work. The parameters are not required to be strictly the same, and may have a certain allowable range of variation. What are the main working parameters of the power adapter? How to buy?

  1. The main working parameters of the power adapter:

  1, input voltage and input current;

  2, output current and output current;

  3, output connector (interface) and output polarity (basically different brands have their own standards);

  Generally, notebook adapters have 110-240V input, which conforms to global international standards.

  Two. Please refer to the following principles for purchasing a power adapter:

  1. The principle is to choose the same brand and the same type. If not, you can only find other brands;

  2. The output voltage of the adapter should be the same as the voltage required by the notebook. If it is different, it should be as close as possible to the required voltage of the notebook and controlled within ±5% of the error. This is because the voltage regulator circuit in the notebook generally has a surplus It can work normally and stably when the input voltage changes within a certain range. If the voltage exceeds this range, the computer may not work stably or even light up the machine; if the voltage is too high, the voltage regulator circuit in the computer may be burned. . For example, an Acer notebook requires 15V, 3.36A input, but it can be used normally with an IBM16V, 3.36A adapter.

  3. The maximum output current of the adapter should be as consistent as possible with the maximum current required by the notebook. If it is different, it should be equal to or greater than the required current of the notebook; Note: As long as the current is large, you don’t have to worry about how large it is. Don't be afraid, don't worry about burning the machine! But the current should not be too small, because unstable conditions such as screen flickering may occur. For example, the adapter of IBMT30 (16V, 4.5A), although it can be safely used on IBMThinkPadT20 (16V, 3.36A), it can also be used on ThinkPadX31 (16V, 3.5A); the principle is: the power adapter adjusts the output according to the load. Electricity is not static. Like the above IBM16V, 4.5A adapter, it can provide a maximum operating current of 4.5A, but when used on T20, it also outputs a maximum of 3.36A. In fact, due to the different working conditions of the notebook computer, the current it needs is constantly changing. The adapter adjusts the output power at any time according to the working condition of the notebook to meet the needs of the computer. Adapters with a higher output current are more comfortable, and have a taste of "killing a sledgehammer". But the reverse is not good. Although the T20 adapter can also light up the T30, the T30 screen sometimes flickers. This is because the T20 adapter cannot stably provide the working current required by the T30.

  4. Finally, this point should have been ranked first, that is the output interface and output polarity of the adapter (note the positive and negative poles). You must first ensure that the purchased adapter can be inserted into your laptop, otherwise it will work. The parameters are exactly the same, but if you can't plug it in, what's the use for you. Due to the independence of major notebook manufacturers, adapter connectors of different brands are different. Each series of notebook adapters of the same brand generally have connectors of the same specification, but sometimes different brands may also use the same connector.
