An external power supply is simply a separate physical enclosure or device that can charge a laptop. It connects to your PC through removable or hard-wired electrical connection, cord, cable, or other wiring, while some models also allow wireless charging. However, an external power supply isn’t just important for charging PCs.
Portable equipment that can operate from a battery pack or an external power source (such as a wall-adapter or external supply) needs to be able to smoothly switch between the two power sources. This application note describes a circuit (Figure 1) that switches power sources with good efficiency and without switching noise. Figure 1.
Yes! The solution is very simple, but you need to take care to not doing anything wrong. So, our solution is using Batteries as external power supply! Some external power supply examples images:
However, an external power supply isn’t just important for charging PCs. With its built-in AC outlet, it can also power other electronic devices, such as smartphones, tablets, video projectors, digital cameras, and baby monitors. Buying an external power supply for a PC can be challenging, considering there is a wide range of options in the market.
Pay attention to the number of output ports your external power supply has. You want to ensure there are enough ports to charge all your devices. Micro USB, USB-C, and lighting are the most popular ports on external power solutions.
External power supplies ranging from 6W to 300W. Cost-effective solutions that keep your products running at peak performance.
