Plugging in your phone to the charger is not a problem but just putting it on the Wireless Qi Charging Pad is so much more convenient. I'm a heavy phone user and run out of battery quite often. I used to plug in my phone in all the time but each time somebody called or I wanted to check my messages etc. I had to unplug it.
Since having this wireless charger one of my phones lay constantly on it. They are always ready to go and fully charged. Wireless charging takes no longer to fully charge my device. I am using this with my Samsung Galaxy s9 and it fully charges without any issues. I'm very happy with this device and therefore I can highly recommend it to anyone looking for a Wireless Qi Charging Pad
