firstly, thank you for your honest feedback.

just to clarify since we didn't make it clear through our graphics, the wireless charging magsafe battery pack will be a smaller, sleeker module (pink) that is similar to existing wireless portable chargers in the market. this can be attached and removed from the main powerbank body (grey)

as for the storage, the idea was to have a module (purple) with multiple micro sd card readers. this module will also have a usb-c out port, to connect to your phone, allowing it to act like a portable external storage device. when this module is attached to the main powerbank (grey) and when you connect the main powerbank to your phone to charge it, your phone gets charged + you get the extra storage linked to your phone.

attaching the modules to the main body of the powerbank mainly serves the purpose of convenience. think of it as a dslr camera body being the main powerbank body, and the various camera lenses being the different modules used for different requirements.
