The amount of time it takes for a 15W wireless charger to fully charge a device depends on several factors, including the size of the device’s battery, the device’s charging efficiency, and any power management features enabled on the device.
Assuming a fully depleted battery and optimal charging conditions, a 15W wireless charger could charge a device with a 4,000mAh battery to 50% in approximately 30-40 minutes, and to 100% in approximately 1.5 to 2 hours. However, these times can vary widely depending on the factors mentioned above.
It’s worth noting that some devices may not support 15W wireless charging, and in those cases, the charging speed will be limited to the maximum speed supported by the device. It’s always a good idea to check your device’s specifications to ensure compatibility with a 15W wireless charger and to confirm the expected charging time.
