In this era of rapid technological advancement, you can find a vast range of charging technologies and methods available. From proprietary technologies like Qualcomm Quick Charge to industry standards such as USB Power Delivery, it can be quite overwhelming.
This overview will provide a comprehensive breakdown of various charging modes, technologies, and cables available to Australian consumers.
* Please note that if the title or the description of the charging accessory we offer at iCoverLover does not mention it is suitable for Apple Watch, AirPods, Samsung Galaxy Watch or Samsung Galaxy Buds the charger is not suited to be used with any of these devices. |
Charging ModesThere are three main types of charging modes: slow, fast, and superfast charging. 1. Slow Charging (5W to 10W): This is the most common charging method, often found in older phone models or budget devices. It's convenient and doesn't require special equipment, but charging times are longer. 2. Fast Charging (18W to 50W): Fast charging technologies, like Qualcomm's Quick Charge or Apple's fast charging, significantly reduce charging times. However, they often require specific chargers and cables to function effectively. 3. Superfast Charging (65W and above): Superfast charging technologies are becoming increasingly common in premium smartphones and tablets. They can deliver astonishingly quick charge times but can potentially heat up the device if used for extended periods. |
Charging Technologies1. Programmable Power Supply (PPS): This USB PD extension allows the device to request fine-tuned voltages from the charger, enabling more efficient charging and reducing heat. 2. Qualcomm Quick Charge: This proprietary technology is found in many Android devices. Quick Charge 4+ and above are compatible with USB Power Delivery (PD), providing up to 100W of power. 3. Gallium Nitride (GaN): GaN is a material used in some chargers to increase efficiency and reduce heat. It's not a charging technology but rather a component that makes chargers smaller, lighter, and more efficient. 4. USB Power Delivery (USB PD): This universal charging standard can provide high power levels, up to 100W, making it suitable for larger devices like laptops. |

1. USB Type-A to Micro-USB: This is the most common type of charging cable. However, it doesn't support fast charging technologies.
2. USB Type-A to USB Type-C: This cable can support fast charging if both the charger and device support it. However, it's less efficient than a full USB Type-C setup.
3. USB Type-C to USB Type-C: This cable supports all fast and superfast charging standards, including USB Power Delivery. It is the most future-proof cable.

General Tips for Australians1. Australian Plug Type: In Australia, the standard plug type is Type I, which has two flat pins in a V-shape plus a grounding pin. Make sure any charger you purchase has the correct plug. 2. Check Your Devices: Always check what charging technologies and power levels your devices support. Using a higher power charger won't speed up charging if your device doesn't support it. 3. Quality Over Price: Invest in high-quality chargers and cables from reputable brands. They are more likely to support the fastest speeds your devices can handle, and they're also less likely to damage your device or become a fire hazard. 4. Heat Management: Fast and superfast charging can cause devices to heat up. If this becomes excessive, it might be safer to switch back to slow charging. |
