When purchasing compatible laptop accessories, especially for AC adapter, many users have less knowledge of its additional functions. Instead, the factors like capacity, can be seen obviously by the appearance and specifications, have been paid more attention by users.



Although HP laptop battery has been talked a lot for accidents, compatible HP adapter is popularized by users for high capacity and low price. As we all know, it is the adapter that determines the charge rate, related with capacity and conductivity. In addition, once the laptop is with overloading operations, a high capacity AC adapter can prevent it from serious damage.



There’s a 120W AC adapter for HP pavilion ZD7000 ZX5000 ZV5000 Presario 3000 R4000 in USB Phone World. In the process of transferring power energy through HP notebook power cord and adapter, there’s heat produced with it. Actually, for this high capacity laptop charger, it needs more batter exterior and interior materials in shell, circuit, stabilizers and so on. Otherwise, with component degradation occurs to HP adapter, it is no longer as good as a 120W one should be.

Furthermore, to be safer, some additional devices installed in AC adapter are necessary to us, such as control circuitry, cut off systems and cooling fan. As is told above that a high capacity charger is at high risk of overheat for internal resistance, even if accidents haven’t happened to users, it needs to cooling fan to get rid of rapid reduction. And the protection tools like control circuitry can prevent the adapter from accidents by cutting off the electricity.



As a matter of fact, HP adapter has taken more efforts on its performance and quality than on capacity and profits. For this reason, it is really a good chance for users to purchasing some for replacement.
