OEM 90w Laptop Charger Adapter for Samsung PC

OEM 90w Laptop Charger Adapter for Samsung PC

• The basic principle is that a large nominal current supply can replace a small nominal current supply. Some friends have the misunderstanding that the large nominal current of the Power Supply will burn the book, because the current is too large. In fact, the current depends on the load when the voltage is the same, that is, the work of the book, when the book is running at a high load, the current is higher, the book into standby, the current is smaller, in short, the current is equal to the voltage on the book divided by the equivalent resistance of the book. A large nominal current supply has sufficient current margin to prevent overheating or low output voltage after replacing a small nominal current supply. On the contrary, the use of small current power supply instead of large current power supply has the above dangers.

• But some friends with 56 w power instead of 72 w, there is no problem with it, the reason is the design of the power adapter usually have certain allowance, load power is less than the power, so that instead of in general use is feasible, but the rest of the power supply power margin is very little, once your laptop to meet a lot of peripherals, such as two pieces of usb hard drive, and then the CPU run at full speed, another base, to read disk drive full speed, and recharge the battery at the same time, the estimate, it will be dangerous, always with the hand touch is your power supply can be boiled eggs. The 72w adapter has 16w more than the 56w adapter to cope with this situation. So it is best not to use small current power supply instead of large current power supply. If you really want to do, conditional friends can think of a way to measure the maximum consumption of your book when the actual need of current, measurement method is very simple, a socket, a plug, an ammeter, a few wires, a soldering iron can be. It is certainly safe if it is within the nominal current of your power supply.
