Frequently Asked Questions
Q: Is this USB flash drive compatible with the latest iPhone models including iPhone 13 and 14?
A: Yes! The JASTER 4-in-1 flash drive includes a Lightning connector that is compatible with iPhone 5S through iPhone 13 Pro and newer models running iOS 8.0 or above. Simply plug it into the Lightning port to access and transfer your files directly.
Q: Do I need to install an app to use this flash drive on my Android or PC?
A: No app installation is needed for Android (via the Type-C or Micro USB connector) or for Windows and Mac computers (via USB 3.0 Type-A). It is true plug-and-play for those platforms. iOS devices may require the associated app for full file management functionality.
Q: Why does my device show less storage than the labeled capacity (e.g. 256GB)?
A: This is normal for all flash memory products. Manufacturers calculate capacity using decimal units (1GB = 1,000MB), while your device's operating system uses binary units (1GB = 1,024MB). This results in a small difference — for example, a 256GB drive typically displays as approximately 230–240GB on your device.
Q: What file types can I store on this 4-in-1 flash drive?
A: You can store virtually any file type — photos, videos, music, documents, PDFs, and more. The drive is great for backing up your iPhone camera roll, transferring movies between devices, or carrying important work files on the go.
