As the performance of mobile devices continues to improve, users have greater expectations for fast charging and data transmission. What should be prioritized when choosing <a href="https://www.adata.com/en/consumer/category/usb-cables/usb-c-to-usb-c-cable/" target="_blank" rel="noopener">Type-C charging cables and chargers</a>? The following four purchasing tips will teach consumers how to choose the product that fits best!
&nbsp;

<a href="https://www.adata.com/en/consumer/category/usb-cables/usb-c-to-usb-c-cable/" target="_blank" rel="noopener">USB Type-C supports both charging and data transmission</a> unlike early Type A cables which could either charge and/or transmit. With Type-C, users will never have to switch cables when a charging cable is mistaken for a transmission cable. However, when choosing Type-C products, users must still be aware of device requirements. Be sure to carefully confirm the input/output wattage and charging protocol of the product. The higher the wattage, the faster the charging process. Therefore, if wattage is lower than what is required by the device being charged, charging speed will suffer. In terms of transmission speed, users must note product specifications. For example, the specification label USB 3.0 means transmission speed is 5Gbps (now collectively known as USB 5Gbps). If a cable supports both data transmission and charging specifications, transmission speed and charging wattage will both be specified. &nbsp;USB 40Gbps transmission speed supports a charging speed of up to 240W.

1.	Charging vs data transmission

What does it mean exactly when a charger or <a href="https://www.adata.com/en/consumer/category/power-banks/power-bank-r100-magnetic/" target="_blank" rel="noopener">power bank is advertised as PD or QC fast charging</a>? There are currently two main types of fast charging technologies: QC (Quick Charge) fast charging and USB-PD fast charging (USB Power Delivery). QC is a technology released by Qualcomm, the largest supplier of Android mobile phone chips. PD is a technology released by the USB-IF Association. It uses the current mainstream USB-C interface specification and is also a fast charging protocol supported by iPhone/iPad.
&nbsp;
The difference between <a href="https://www.adata.com/en/consumer/category/power-banks/power-bank-r100-magnetic/" target="_blank" rel="noopener">PD and QC fast charging technology</a> lies in charging power and dynamic adjustment range. PD can support up to 240W and QC can support over 100W. When comparing the two, PD supports a variety of voltages and currents, has wider compatibility, and can be dynamically adjusted according to the needs of the device and the capabilities of the charger for the best charging results. QC is Qualcomm's unique charging protocol. It is mainly used in devices using Qualcomm chips. If these two protocols are still confusing, the best option is purchasing a charger with both QC and PD fast charging standards to ensure the best compatibility.

When purchasing a <a href="https://www.adata.com/en/consumer/category/chargers/charger-65w-gan-usb/" target="_blank" rel="noopener">Type-C charger</a>, in addition to paying attention to the charging wattage, users can also choose <a href="https://www.adata.com/en/consumer/category/chargers/charger-65w-gan-usb/" target="_blank" rel="noopener">a gallium nitride (GaN) charger</a> which provides higher power density and efficiency compared to traditional silicon chargers and can charge faster while reducing heat generation and ensuring high power output. At the same time, the use of <a href="https://www.adata.com/en/consumer/category/chargers/charger-65w-gan-usb/" target="_blank" rel="noopener">GaN technology</a> can significantly reduce the size of the charger, making these chargers easier for users to carry and more suitable for travel.
&nbsp;
However, to fully utilize the performance of a high-wattage charger, users must choose a charger suitable for the device to be charged. Users must also pay special attention to using appropriate <a href="https://www.adata.com/en/consumer/category/usb-cables/usb-c-to-usb-c-cable/" target="_blank" rel="noopener">Type-C cables</a> and observing device precautions. When selecting Type-C cables, identify products with high current carrying capacity that can handle currents of up to 5A, thereby achieving a maximum power output of 240W. As an alternative, choose a product with a built-in E-Marker chip which allows the charger and device to identify and charge efficiently at the correct power level.

3.	Materials, quality, and performance are closely related

When making a purchase, users should also pay attention to whether the product complies with relevant safety standards and certifications. The easiest way to do this is to choose a well-known brand or reliable manufacturer to ensure the quality and durability of the product. These brands also have relatively complete warranties and after-sales services. This prevents situations where users have no recourse when problems arise. Furthermore, when using a high-wattage charger, special attention should be paid to compatibility with the device to be charged. Not all devices support fast charging. If an incompatible charger is used, charging will not only fail but may even cause damage.
&nbsp;
In addition, it is also critical to ensure the environment is conducive to heat dissipation when charging because high-power charging will generate more heat. Check the condition of the charger and cables regularly.&nbsp; Do not ignore any visible damage as this may reduce charging efficiency or cause accidents. Warranty and after-sales service: ensure the warranty period is adequate and after-sales service satisfactory in case any problems arise.
