12V3A Adapter Switching Power Supply For Massager For AUS

More Power Adapter FAQ
1, are the same nominal voltage power supply, the output current is different, can be used in the same notebook?
Power supply voltage is the same, the output current is different, can not be used in the same notebook, the basic principle is that a large nominal current power supply can be replaced by a small nominal current power supply estimates that some people would like to think so, think that a large nominal current power supply will burn the notebook, because the current is large. In fact, how much current in the case of the same voltage depends on the load Oh, think about the physics of junior high school know. When the book is running under high load, the current is larger, the book into standby, the current is smaller, large nominal current power supply has enough current margin. On the contrary, some people use 56w power supply instead of 72w with no problem, the reason is that usually the design of the power supply live orchestrator to leave a certain margin, the load power are less than the power supply power, so this substitution is feasible in general use, but the remaining power supply power margin is very little, once your notebook connected to a lot of peripherals, such as two usb hard disk, and then the CPu running at full speed, and then there is A dock with an optical drive on it reading disks at full speed, plus charging the battery at the same time, it's probably dangerous to keep your hand on your power supply to see if it's ready to boil an egg. So it is best not to use a low-current power supply instead of a high-current power supply.
2, exactly the same machine, other people's power supply warm, my always very hot, why?
Do not suspect that your power supply has a problem, first look at your book in thousands of what, is not like the above said two USB hard disk, CPU running at full speed, hard disk read and write madly, CD-ROM drive full-speed reading disk, at the same time to the battery charging, loud music, the screen brightness is the largest, the wireless card has been detecting signals, and so on, make good use of the power management, according to the task of the work of the book to adjust the working state is very important.
3, the nominal voltage of the power supply is much higher than the battery voltage of my laptop, it will not happen, right? First of all, it is important to know is that the power supply to the notebook power supply and battery power supply to the notebook is a different battery power supply, the output of the battery is pure DC, very clean, the battery voltage can not be and do not need to design a very high, the chemical characteristics of the carp battery decided a cell output voltage can only be in the 3.6V or so, so a lot of batteries are used in a three-stage series connection, 10.8V has also become very popular battery voltage. Voltage. Some batteries have a nominal value slightly larger than an integer multiple of 3.6V, such as 3.7V or 11.2V, etc., which is actually to protect the battery.
