A fast charging Lightning cable enables faster charging speeds for Apple devices compared to standard Lightning cables. Specifically, a USB-C to Lightning cable is what allows for fast charging, providing significantly more power than the older USB-A to Lightning cables.
USB-C to Lightning vs. USB-A to Lightning
The key difference lies in the type of connector used on the power source end of the cable:
-
USB-A to Lightning: This older standard is limited in its power delivery. According to references, it typically supports a maximum of 5V/2.4A/12W when charging iOS devices.
-
USB-C to Lightning: This newer standard, when paired with a compatible USB-C power adapter (charger), unlocks faster charging capabilities. The reference indicates that it can support up to 9V/3A/27W depending on the specific device.
Benefits of Using a USB-C to Lightning Cable for Fast Charging
- Quicker Charging Times: Devices charge much faster, reducing the time spent plugged into a power source.
- Increased Power Delivery: USB-C to Lightning cables support higher wattage, allowing devices to draw more power and charge more rapidly.
Practical Example
To leverage fast charging, you'll need:
- A device that supports fast charging (e.g., iPhone 8 or later).
- A USB-C to Lightning cable.
- A USB-C power adapter (charger) that supports Power Delivery (PD). These chargers are typically rated for 18W or higher.
| Cable Type | Charging Capability |
|---|---|
| USB-A to Lightning | Limited to 12W |
| USB-C to Lightning | Up to 27W |
