Customers find the power bank’s build quality solid and appreciate its portability for travel. The charging speed and functionality receive mixed reviews – while some say it charges devices quickly and works well, others report poor performance. The battery life and value for money also get mixed feedback, with some saying it holds power for days and is worth the price, while others note it doesn’t hold a consistent charge and consider it overpriced. The weight is a concern, as customers find it heavy and not easy to carry around.
