It is important to have universal adapters and charging facilities. I believe that most domestic and international users bring their own adapters and charging equipment with them. However, there are times when users may lose or break their adapters or charging equipment due to unforeseen accidents during their trip. If the user notices this in the middle of the night, it may happen that there is no convenience store open 24 hours a day in the vicinity and the user is unable to make a purchase. Nowadays, charging facilities for smartphones and other electronic devices are a necessity in our daily lives. If you have universal adapters and charging facilities in case of an accident, your users may really appreciate it. Properties with this kind of attention to detail will increase user satisfaction over time, which will greatly contribute to increasing asset value.
