Customers say
Customers find the power bank excellent in quality and appreciate its built-in cords, making it perfect for travel and daily use. Moreover, they consider it convenient to charge on an outlet and easy to use. However, the charging speed and functionality receive mixed feedback – while some say it charges devices quickly and works well for some time, others report it fails to charge itself and stops working after one month. Additionally, durability is a concern as the device breaks after 10 charges and 6 months, and customers find it heavy and bulky.
