In this article, we’ll delve into the world of power banks and explore the possibilities of laptop damage.
Understanding Power Banks and Laptops
Before we dive into the possibility of power bank damage, let’s first understand how power banks and laptops work.
A power bank, also known as a portable charger, is a battery-powered device designed to charge electronic devices on the go. It’s essentially a battery with a USB port that allows you to charge your devices. Power banks come in various capacities, ranging from a few hundred milliampere-hours (mAh) to several thousand mAh.
On the other hand, a laptop is a complex electronic device that consists of a battery, central processing unit (CPU), memory, storage, and other components. Laptops have their own battery management systems (BMS) that regulate the flow of power to the device.
How Power Banks Charge Laptops
When you connect a power bank to a laptop, the power bank’s USB port supplies power to the laptop’s battery. The laptop’s BMS takes over from here, regulating the flow of power to the battery. The power bank’s output voltage and current are matched to the laptop’s input requirements, ensuring safe and efficient charging.
However, there’s a catch. Most power banks are designed to charge smaller devices like smartphones and tablets, not laptops. Laptops require more power to charge, and not all power banks are capable of delivering the required voltage and current. This is where things can go wrong.
