The mobile phone is used for researching and for entertainment, I frequently use it because of researching. My experience in using it is great because you can search what you want anytime and it also bring you entertainment.
The power bank is used for charging phones and other kinds of devices, I only use it when I am outside or when there is no electricity available. The power bank is so useful because you can charge your device anytime and anywhere.
The headset or earphone is used for listening to music while not disturbing anybody that is surrounding you, I only use it when it is noisy and I need to listen to something important. The headset or earphone is a great device because you can listen to music anytime you want without distracting or disturbing anybody.
