The dangers of cheap power banks

When looking to buy a backup charger, consumers often encounter many different price ranges, from a few hundred thousand to several million Dong.

Many people may think that all power banks are the same, but that is not the case. High-end products not only provide charging but also cooling for the phone, ensuring efficiency and safety. On the contrary, cheap models often have inaccurate capacity and may be made from recycled batteries and low quality.

Before deciding to buy a cheap power bank, users should be aware that they can do more harm than good to their phones. Some cheap models lack important features such as voltage regulation and surge protection, which can lead to battery drain, slow charging, or even serious damage to the phone's internal components.

Using a cheap power bank can affect the lifespan of your phone. Every device is designed to receive power within a certain voltage range, but because cheap power banks often do not regulate the voltage properly, this can lead to overcharging and high temperatures that damage the battery over time. Furthermore, poor quality power banks can pose a fire risk, especially if they are made from substandard components.

Notes when choosing to buy a backup charger

When buying a power bank, pay attention to a few important factors. First, check if the product is certified by reputable agencies. Second, consider the output specifications as a quality charger will maintain a stable voltage, while a cheaper model may produce unstable voltage pulses, affecting the battery's performance.

Finally, look for additional features like overcharge protection, short circuit detection, and temperature regulation. These features not only protect your phone, but also prolong the life of both the power bank and your device.
