With the development of fast-charging technology, some new out laptops have come to start with fast-charging power adapters. Compared to the traditional laptop power adapter, what are the advantages and disadvantages of this laptop PD fast charging?
Compared with the traditional laptop power adapter, the most obvious one advantage of the laptop PD fast charging is the small size, light weight, generally weighing between 160g to 250g, can be easily stuffed into the bag, easy to carry. Secondly, PD power adapters generally use Type-C charging interface, positive and negative can be checked, not easy to damage the charging interface. Comes with a variety of charging voltage segments, in addition to the computer can be charged, you can also charge cell phones, tablets and other devices. But this laptop PD power supply is not without its drawbacks.
First of all, with the current power supply technology, no matter when the ordinary charger comes PD power adapter, charging work when the energy conversion efficiency can not be not 100%. In the conversion of alternating current into straight current, a considerable portion of the electrical energy loss will be generated and emitted in the form of heat energy. And now the notebook power consumption is large, in order to be able to use for a long time, many people choose to play while charging. This has high requirements on the power adapter's heat dissipation ability to consider. Compared with the traditional notebook power adapter, the relatively small size of the PD power is relatively poor heat dissipation capacity, if manufacturers want to design a compact size is not easy to heat PD charger, we must improve the conversion efficiency of electrical energy. In this way, the cost of the charger is relatively high.
Secondly, the laptop fast charging power adapter and cell phone fast charging charger are the same metal two-pin plug, and the volume to be a little larger. Inserted in the socket is likely to occupy the other socket location, not convenient to use, and this laptop fast charging source is heavier than the cell phone charger, if inserted in the wall or inserted vertically into the plug socket, the probability of insertion is not stable.
The traditional laptop power adapter, although large and heavy, but the use of triangular AC plug, inserted in the socket, do not have to worry about occupying the location of other outlets, and do not have to worry about it plug unstable.
