677 Wh · 600 W output · LiFePO4 · $799
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
The largest of the rugged compacts. Still not an appliance unit — 600W of output caps what it can drive — but a durable mid-size companion.
Best for: Rugged off-grid use where durability outranks running heavy loads.
What we like
- IPX4-rated aluminum housing
- 4,000 cycles
- 677Wh covers a long weekend of devices
Where it falls short
- 600W output rules out compressors and heaters
- 20.3 lb is heavy for 677Wh
