300W High-Capacity Power Bank: Powerful and Versatile for Multiple Devices
This 300W high-capacity power bank is not only powerful but also suitable for a wide range of devices. Its quality is guaranteed, providing you with stable and reliable power support.
Type-c:PD protocol 100 watts bidirectional, supporting four sets of voltage identification input and output from 5-9-12-15-20V.
USB:QC3.0 port independent output, 18W Support 5-9-12V intelligent recognition.
voltage balancing circuit: Due to subtle industrial errors, there are capacity differences among lithium batteries of the same model. However, most power banks have overcharge and discharge protection, but there is no voltage balancing circuit set up. There is no difference in short-term use. Over time, this difference will gradually be amplified, and batteries with smaller capacities will enter protection in advance. Some batteries cannot be fully charged and discharged, resulting in a sharp decrease in overall capacity. The voltage balancing circuit aims to balance this difference, significantly improve the cycle life of battery cells, and eliminate safety hazards such as bulging and leakage.
