✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
Goal Zero's compact entry: rugged and IPX4-rated, but you pay a premium over similar-capacity rivals for the drop-and-splash toughness.
Best for: Overlanders and job sites where the unit gets wet and knocked around.
What we like
- IPX4 water and dust resistance is rare this small
- 4,000-cycle LiFePO4
- 50-minute recharge
Where it falls short
- 350W output runs devices, not appliances
- $299 for 297Wh is pricey per watt-hour
