In today’s modern world, it can be annoying to wait hours for your mobile phone to charge.
And that’s where fast charging comes into action. To fully understand how fast charging works, it is important to know the basics of watts, amps, and volts, as well as how they function with the USB cable or mobile charger cable.
The reason behind fast charging
Whenever we plug in our phones, the electricity from the power adapter flows through the USB charging cable to our phones. The charging speed is usually determined by:-
- V(Volts): the amount of electrical pressure that pushes electricity through your phone.
- A(Amps): amount of electrical current.
- W(Watt): total power delivered (calculated by multiplying volts and amps)
For example, a 9V/2A charger will deliver 18W of power, which means fast charging.
Importance of choosing the right cable
All USB cables are made differently. The quality and thickness of the wire inside the mobile charger cable greatly affect the amount of current it can safely transfer. Using a damaged or low-quality cable may considerably slow down the charging speed or may even damage your devices.
A genuine and superior quality USB charging cable guarantees that the power flows smoothly and efficiently without overheating.
Various charging standards
Standard charging: typically delivers 5V/1A or 5V/2A, which is usually slower.
Fast charging: In this type of charging, volts and amps are increased, resulting in fast charging. Such a type of charging is also known as adaptive fast charging or quick charging.
USB-C Power Delivery: This format is the new universal type of charging that supports up to 100W of charging with USB-C cables.
How to choose the best mobile charger cable
While buying a USB charging cable, make sure to keep the following factors in mind:
Phone compatibility: Make sure that the mobile charger cable is compatible with your phone’s charging power input.
Cable type: many new phone models have a USB-C type charging port, while older ones may still have a USB-A or micro USB port. Opt according to your phone’s charging port.
Durability: Reinforced or polyester braided cables are usually long-lasting. And if we talk about durability, Elver polyester braided USB cables are built to last.
Current rating: Buy a USB cable that supports at least 3A for better charging speed.
How to maximise fast charging
Use an authentic and original mobile charger cable that came with your phone.
Avoid charging your phones with duplicate and cheap-quality adapters.
Make sure that the temperature of your phone is normal while charging; the charging speed slows down when the phone is overheated.
Avoid using the phone while it's charging; multitasking may slow down the charging speed.
Final thought
The charging speed of smartphones has comparatively increased over the years. Fast charging is not only about the adapter; the USB cable also affects the charging speed.
By understanding amps and watts, you can choose the right USB charger cable for fast charging of your smartphones.
