Why USB-A?
For Chargers You Already Own
Same Smart Backup. Classic Connector.
Not everyone has switched to USB-C chargers yet. Qubii Duo USB-A plugs directly into any standard USB-A charger or power adapter — the kind that came with your older iPhones or Android devices. Same automatic backup magic, zero adapters needed.
Universal USB-A Port
Works with any USB-A charger, power bank, or wall adapter — no dongle required.
Incremental Smart Backup
Only new content is copied each night. No duplicates, no wasted time.
Multi-Device Support
The whole family can share one Qubii — each device gets its own private folder on the microSD card.
