[0002] Mobile power, also known as power bank, travel charger, etc., is a portable charger that integrates power supply and charging functions. It can charge mobile phones, tablets and other digital devices anytime and anywhere. It is generally composed of lithium batteries (or dry batteries, which are less common) as power storage units. It is convenient and fast to use. PD fast charging refers to fast charging technology, which is a standard for charging mobile devices. PD fast charging technology achieves faster charging speed by increasing voltage and power capabilities. Compared with traditional USB charging methods, PD fast charging can provide higher power output, allowing devices to charge faster.
