It is learned by more and more users that solar laptop charger can be carried here and there randomly while it is frequently to be universal to all kinds of laptop computers. However, pit against an electronic one, except for solar energy, how much has been changed in charge principle?



The HP Compaq laptop AC power adapter I use to use in the office comes to be a typical laptop charger in the market. Once plugged into the outlet, it keeps in the condition of charge holding with continuous external power energy consumed. Even if a charge switch is available there, it still cannot get rid of consumption in internal circuits while more and more internal resistances produced.

Comparatively, although solar laptop charger will also receive solar energy when it is out of work, it seems that utilization rate of power energy comes to be higher with less internal contamination. In my point of view, solar chargers are more similar to laptop battery. HP adapter provides power energy to laptop by split-flow from external power supply while the solar ones stored the solar energy inside the transformer.



When provide electricity to laptop, it has to transfer the chemical energy to electronic energy, which has been stored inside laptop charger for a while. That is to say, even if there’s no sunlight available to users, there’s still power energy supplied to laptop. Furthermore, according to its unique principle, we can also be regarded it as a battery, which will be more powerful than HP adapter.



Anyway, as technology hasn’t developed to be so mature as we expected, maybe we should keep HP Compaq laptop AC power more further. And I still believe that solar laptop charger will definitely change our life and work a lot in the near future.

Although I have taken part in the industry of AC adapter for a period, I haven’t thought hard about the meaning behind it. It was until one of my friends told me that he had received a gift HP 402018 001 from his business partner that I realized more about it.


In the process of laptop running, the AC adapter seems to be a necessary but not significant tool to provide enough power energy. Without it, the laptop cannot work normally. If it occurs to be damage, we will be troubled for its special designed in electricity voltage, mains frequency, cut off system and so on. All these make the charger a unique one to laptop instead of a universal for all.


This gift of HP Compaq laptop AC power adapter, HP 402018 001, as is compatible with only several HP and Compaq laptop series, we can see care and support from the giver.


First, from the AC adapter, we have learned that the business partner is care about my friend. If he has no idea of his daily life, he can’t find a suitable one for his laptop. And the gift has really surprised my friend a lot and he is moved by his partner.


Besides, as HP Compaq laptop AC power adapter is a supportive part to the computer, it has just shown the relationship between my friend and his business partner. Normally, the transformer is to provide appropriate power energy to laptop while protect it from over charge by cut off system.


Last but not least, this gift of AC adapter has reminded my friend of his business partner frequently in the process of working. And compared to his colleagues, his laptop computer performs more smoothly and stably, which has improved his work efficiency a lot. And I just can’t help to respect his business partner to have such a good idea.

It seems to be our nature that it is not until we lose the former performance of AC adapter that we begin to realize the importance of the adapter. By comparison, we see more clearly about its advantages and the convenience it provided than before. However, it is late for us to treasure every happy moment with the adapter.

As AC adapter is always a silent contributor with less contact with us, we often disregard its feelings while it is sensitive really. Actually, after burned by the heat of the adapter, we will realize how much pressure has been added to the little device. Even so, it still works hard to provide enough power energy to laptop battery and the other components.


HP Compaq laptop AC power adapter is a 65W AC adapter that I used to use. Although it is not so powerful that I was surprised a lot, it really has provided me a good work condition with continuous power energy and stable charging period. At that time, I haven’t imagined that one day it will be sick if not kept in good repair. No wonder people always say that young people always take their good fortune for granted.


As a matter of fact, the damage comes earlier to the Compaq laptop power cord than the AC adapter. Since every time I wound the power cord around HP Compaq laptop AC power adapter after use, a problem cropped up to its interface of poor contact.


Afterwards, I found that it does not only happen to the Compaq laptop power cord but the whole adapter as well. By the time I realized the size of the problem, it was too late to activate it that I have to replace the whole AC adapter.


As far as HP Compaq laptop AC power adapter is concerned, it is not only an external charger but also a necessary part of my HP laptop. If possible, I might have maintained it good and kept it with me for at least three years.
