It is important to note that when using a charger with a lower current rating than the device requires, it can result in slower charging times. However, as long as the voltage requirement is met, there should be no adverse effects on the device's performance or safety. Additionally, it is important to carefully check the charger's specifications to ensure compatibility with the device. Overall, using a 5V 2A charger with a 5V 3A device is safe and should not cause any issues for most devices..
