Yes. One Picture Keeper can back up more than one device — computers, phones and tablets — including a mix of Apple/Mac and PC/Windows machines. Each device's files are saved into its own folder on the drive, so one device's backup does not overwrite or mix into another's.
Backing up a phone or tablet does require a model that connects to mobile devices. You can check yours on the Product Compatibility Chart.
Where each device appears
Once you have backed up a second device, both are listed on the drive. In the mobile app, tap PK Drive and then All Devices at the top to choose which device's content you want to look at. In the computer app, click Files on PK Drive to browse the folder directory, which mirrors the folders on each device it copied from. There is more detail in How do I view files on my Picture Keeper?
One drive, or one for each
Keep in mind that backing up several devices to a single Picture Keeper will fill it up more quickly. If there are a lot of photos and videos spread across your devices, you may prefer to use a separate Picture Keeper for each one, so there is always enough room for all of them.
