subject: Heavier Laptop AC Adapter Has Better Performance? [print this page] It's said that the heavier, the better for the laptop battery. is this saying right or wrong? to be frank, I have the same idea that the heavier AC adapter has better performance. Some times I will take this way to measure the quality of the adapter. Like thisDell 300M AC adapter, I don't think it's good enough for it's not so steal and heavy for me. Actually this is not scientific.
On the behalf of the consumers, they prefer to buy a worth product. Like this Dell E1705 AC adapter, manufacturers must improve the purchase value. That is to say, they want to spend the least money but the best products. Therefore, the manufacturers must continue to carry out technological innovations, while maintaining the performance of the same circumstances, to further improve product integration, new materials, and new design concepts to reduce costs.
So why people have this concept that the heavier adapter has better performance? To some extend, this concept is right. First of all, EMI circuit is one of the most important test factors of the CCC and also one that can reduce electromagnetic radiation of the AC adapter like this dell 1520 AC adapter. In the past, EMI circuit has several levels in order to meet the CCC requirements. However, with the components of performance improvement, only part of the circuit can achieve the requirements of the CCC. In particular the relatively low power supply, due to lower electromagnetic interference, generally the EMI is only one X capacitor. Of course, the high power supply EMI circuit is relatively complex and heavier. And that is why people think the heavier adapter has better performance.
However, as the development of the technology, the PFC which is one of the important components of the adapter has reduced its weight. Like the DV8000 AC adapter, it has adopted ceramics or plastics instead of the traditional metals. And everything has changed day by day. we should not stick to the old theory. In addition, keep our mind updated as the development of the laptop technology.
