Portable 4TB storage with 5000mAh power

This accessory combines a 4TB hard drive and a 5000mAh battery in one unit. It is built for iPhone, iPad, Android phones, Mac and Windows PC users who need extra space for photos, videos and files while away from a wall outlet. The MFi certified connector ensures stable transfers with Apple devices.

Plug-and-play expansion for mobile and desktop

Connect the drive directly to an iPhone, iPad, Android handset, Mac or Windows PC and it appears as external storage without driver installation. The built-in battery powers the hard drive during mobile use so the host device does not supply all the current. It frees up internal space on the phone or tablet by offloading large media libraries.

App-driven backup and direct capture

The companion app provides one-tap backup of the camera roll and only copies new items on subsequent runs to prevent duplicates. An in-app camera function saves photos and videos straight to the drive instead of filling local storage. This workflow suits travellers and families who want automatic organisation without manual file management.

Questions about this item

How long can the built-in 5000mAh battery power the 4TB drive during continuous file transfers?

The 5000mAh battery is designed to keep the drive running for extended mobile sessions, but exact runtime depends on transfer intensity and connected device power draw.

Does the 4TB HDD generate noticeable heat or fan noise when left plugged into an iPhone for all-day backups?

The drive uses a mechanical hard disk with no active cooling fan; it warms slightly under sustained use but remains silent during operation.

Which iOS version must my iPhone 15 already run for the one-tap backup app to work?

The companion app requires iOS 11 or later, so any iPhone 15 shipping with iOS 17 is fully compatible out of the box.
