Overview
A phone and a laptop on the same desk can share this drive, which has a USB-C plug on one end and a USB-A plug on the other. The swivel design folds away the connector not in use, and a keyring hole is built in.
Freeing up phone storage and moving photos to a computer is the clear use, with no adapter needed. The limitation is write speed, which trails the read rate, and the backup app needs installing.
Who it's for
A person who shoots photos on a USB-C phone and edits on a laptop with USB-A can share files without adapters. Mobile devices need a Type-C port with On-The-Go support.
Pros and cons
- Type-C and Type-A in one drive
- Swivel protects connectors
- Automatic backup support
- Fast read speed
- Write speed trails read speed
- Backup app needs download
- Phone must support OTG
- Phone model compatibility list not in listing
Performance notes
Read speed is much higher than write speed, so opening files is quick while large copies onto the drive take longer. The swivel exposes one connector at a time and protects the other. The companion app can back up photos, videos, music, documents and contacts from a phone.
