In general, a higher wattage wireless charger will provide faster charging than a lower wattage charger. A 15W wireless charger will generally provide faster charging than a 10W charger, as it can deliver more power to the device being charged.
However, the charging speed will also depend on the device being charged. Not all devices are compatible with fast wireless charging, and the charging speed will be limited by the device’s charging capabilities. So, if you are using a wireless charger that is capable of delivering more power than the device can handle, it will not charge the device any faster than the device’s charging capabilities.
It is always important to check the specifications of your device to see what charging speeds it supports and choose a wireless charger that is compatible with your device. Some devices only support a maximum charging speed of 10W, while others may support up to 15W or even higher.
In summary, a 15W wireless charger can provide faster charging than a 10W charger, but the charging speed will also depend on the device being charged and its charging capabilities. It is important to choose a wireless charger that is compatible with your device’s charging specifications to ensure the best charging performance.
