Many different aspects affect the pricing of a power bank module. Its capacity is one of the most important power bank module features because larger power bank modules are likely to cost more. Take, for instance, a power bank module which is meant to charge smartphones several times, it will surely be more expensive than a lower-capacity power bank module. Additionally, the price also depends on the integrated components like the battery cells and the circuitry used to charge the power bank module. If a module contains more sophisticated battery cells and advanced charging technology like fast charging, the module is likely to cost more. Moreover, brand reputation and demand for the product will also affect pricing. The prices may increase if the supply of power bank modules is high, and if the demand is high, the prices may increase too.
