iPhone USB Drive Media Player Support

Apple devices are not supporting to play all the media formats that we want. Just in case, if you have MP4 or 3GP video files on your backup drive, you may need additional apps to play these files on your iPhone.

Please check the drive apps before you buy the backup drive and make sure the app is supporting all the video/audio formats you need. Most of the drive supporting apps are coming with built-in support for eBooks, major video, and music formats. This lets you read eBooks, view images, and stream videos directly from the drive on your iPhone or iPad screen.

Please be aware that you can’t transfer recorded voice memos, media files (DMCA Files) downloaded from iTunes or other 3rd party apps, those files are DRM (Digital Rights Management) protected. iPlugmate for HooToo can open the VLC player to run the video file directly from the drive itself and support the formats like MKV, MPG formats that can’t play directly on iOS and can buy HooToo iPhone Flash Drive USB 3.0 from Amazon.

All the USB drives are formatted into the FAT32 format by default, which is compatible with both MAC and Windows. The only downside of FAT32 format is, it can support only up to a 4GB size of a single file. But you can transfer the files bigger than 4GB by reformatting these USB drives into exFAT format that will support both Windows, Linux, and MAC operating systems.

Lightning Connector Length


The USB backup drive is coming with a lightning connector to connect with the iPhone. This lightning connector length is very critical if you are the one using a protective cover with your iPhone.

The  drive has an extra 4mm extension that makes sure you can properly insert this drive to the iPhone lightning connector even with thick iPhone cases.

All these USB drives will support old iOS versions and make sure the drive you are planning to buy is going to support that particular iOS. As you know, the old drives have 30pin connector instead of lightning port, but these USB drives are coming with lightning port. You can still use these drives with the help of a converter that can convert the lightning port to an old Apple 30pin port.
