AFERIY P280-B Expansion Battery | 2048Wh (Compatible with P280 Only)

⚠️ This expansion battery does not work as a standalone unit. It requires the AFERIY P280 Portable Power Station to function.

Each P280-B Expansion Battery adds 2048Wh of LiFePO4 capacity to your P280 system. Add one pack for 4096Wh total, or stack up to four packs to reach 10,240Wh — enough to run a household through multi-day power outages or sustain a full off-grid setup for extended periods.

The P280-B connects to the P280 main unit via parallel cable and recharges through the host station using AC, solar, or car input — no separate charger required. Each expansion pack also includes built-in USB-A and USB-C ports for direct device charging.

Best for: Extending P280 runtime for outages • Full-time off-grid living • RV full-timing • Medical device users needing extended reserve
