Tips: Precautions of Desktop AC/DC Adapter.

The nominal voltage of the power supply is much higher than the voltage of my laptop battery. Will there be some accidents?

First of all, it is important to know that there is a difference between the power supply for the laptop and the battery for the laptop. Powered by battery, the output of the battery is pure DC, which is very clean. The voltage of the battery is neither possible nor need to be designed very high. The chemical characteristics of the lithium battery determine that the output voltage of a battery cell can only be around 3.6V, so many batteries use a three-stage series connection, and 10.8V has become a very popular battery voltage. The nominal value of some batteries is slightly larger than an integer multiple of 3.6V, such as 3.7V or 11.2V, etc.

Power supply, the situation is more complicated. First, the added voltage needs to be further stabilized and filtered to ensure stable operation when the power supply performance is not very good. The stabilized voltage is divided into two parts, and the notebook is powered all the way. The other way is to charge the battery. The part that supplies power to the laptop is the same as when the battery is powered. The part that charges the battery needs to be added to the battery cell through the battery's charge control circuit. The control circuit can be very complicated, so the power supply voltage It must be greater than the cell voltage to have sufficient capacity to supply each unit of the charging control circuit. Finally, the voltage actually added to the battery cell will never be the nominal voltage of your power supply.

A suitable power adapter requires safety certification, and a power adapter with safety certification can protect personal safety. To prevent electric shock, fire and other dangers.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
