60W Replacement Laptop Notebook Charger for TOSHIBA

• The nominal voltage of the power supply is much higher than the voltage of my laptop battery. First of all, it's important to know that a power supply for a laptop is not the same as a battery for a laptop. Battery power, the battery output is pure dc, very clean, the battery voltage is neither possible nor need to be designed very high, the chemical characteristics of lithium battery determines the output voltage of a battery cell can only be about 3.6V, so many batteries are adopted three-stage series, 10.8V has become a very popular battery voltage. Some batteries have nominal values that are slightly larger than an integer multiple of 3.6 volts, such as 3.7 volts or 11.2 volts, to protect the battery. 

• Power supply, the situation is complicated, you first need to add further zener voltage filtering, so as to ensure the power supply stable work performance is not good situation, zener voltage is divided into two parts, all the way to power a laptop to work, the other all the way to recharge the battery, to power a laptop with the part of the battery at the same time, and the part of the need to recharge the battery through the battery charging control circuit can be added on the batteries, control circuit can be complex, so the power supply voltage must be greater than have sufficient power supply to recharge batteries voltage control circuit of each unit. The final voltage actually applied to the cell will never be the voltage that your power supply nominal. Don't worry. A suitable power adapter is required to have safety certification, and a power adapter with safety certification can protect the person's safety. To prevent electric shock, fire and other dangers
