Shared power bank can be an emergency measure for a dead cellphone to a certain degree. But there is still some space for discussion whether it is really practical.
First of all, we have no idea about the internal batteries and other configuration parameters of these shared mobile power banks. And it cannot be ensured whether it would cause damage to the phone battery, even lead to security incidents.
Secondly, it is relatively expensive to pay a deposit over $10, even if it can be returned and refunded at any time. Which is not conducive to the popularization of sharing services. Some people with stronger wariness may forgo the use the shared power bank.
Thirdly, similar to the public charging station, sharing power bank for cellphone maybe remoulded by criminals with less supervision to steal consumers’ background information, such as transaction records, passwords and other privacies.
Therefore, you’d better cooperate with an enterprise with high credit when choosing a supplier for the shared power bank, so that consumers don’t need to worry about the refund of deposit and their user privacy data can also be well protected when they use them.
At the same time, enterprise should carefully choose the sharing power bank factory. In general, the power banks produced by manufacturers with premium technology and production equipment must be evaluated and tested by professional certification agencies (CE, RoHS, FCC, etc.). So the cellphone can be charged in compliance with requirements, and the product quality can be guaranteed.
Anyway, what the shared power bank should be like in your idea?
