Not all Smart devices support USB fast chargers.
If a Smart device does not support fast charging, using a fast charger may result in:
Slower charging
Or no charging at all
How Does a Fast Charger Work?
A USB fast charger delivers higher power than a standard USB charger. This is achieved through special charging protocols such as Quick Charge or Power Delivery (PD). These protocols communicate with the device to determine how much power should be delivered.
Since not all Smart devices currently support these protocols, a device may enter a slower charging mode or refuse to charge.
Advice
Preferably, always use the standard USB charger supplied with your Smart device. This has been tested for compatibility and ensures safe use.
If the supplied charger is missing or unavailable, use a standard 5V USB charger with a minimum of 1 ampere.
This ensures a safe and reliable charging experience without risking damage to your Smart device.
