With many iPhones limited to 16GB of memory, Blade4000 offers a solution, allowing users to breakthrough the limitations of onboard storage and cloud services, and seamlessly stream media files including music, videos, and photos straight from the power bank’s card reader. The card reader supports anywhere from 8BG all the way to 256GB to maximize storage space. That's what we are always missing.
