Can someone please tell me which is best for charging speed: USB-C to C or USB-A to C?
When it comes to charging speed, the type of cable and charger plays a key role. Generally, USB-C to C cables are faster and more efficient than USB-A to C, especially when paired with a high-powered charger that supports Power Delivery (PD). Here's why:
USB-C to C Charging:
·Faster Data Transfer & Power Delivery: USB-C is designed for faster data transfer rates and can handle higher power, up to 240W in newer models. This allows for quick charging of smartphones, laptops, and other devices.
·Compatibility with Newer Devices: Most new devices, including laptops, phones, and power banks, are moving towards USB-C as it supports higher wattages for fast charging (20W, 30W, 45W, or more).
·Power Delivery: USB-C to C cables are designed for Power Delivery (PD), a standard that enables fast charging by negotiating the voltage and current between the device and charger, ensuring maximum efficiency.

USB-A to C Charging:
·Slower Charging Speeds: USB-A is an older standard that doesn't support the same level of power delivery as USB-C. Even with a high-wattage charger, USB-A to C cables often max out at 15W-18W, meaning slower charging times.
·Compatibility Issues: While many devices still support USB-A for compatibility, it isn't optimized for newer fast-charging technologies.
·Proprietary Protocols: Some older devices may require USB-A to C charging, especially with proprietary charging systems, often found in certain phone brands, which do not fully comply with USB-C standards.
Device & Charger Compatibility:
·Dedicated Chargers Matter: Charging speeds are not just about the cable but also the charger. Laptop ports, for example, typically don’t provide high-power output. To get the fastest charging speeds, use a dedicated USB-C PD charger.
·Non-Standard Devices: Some devices, particularly from brands using proprietary tech, might only work with specific USB-A to C cables and chargers. However, for most standards-compliant devices, USB-C to C is the fastest.
Make sure to check your device's power input requirements and use a charger that matches or exceeds that for the best results!
