768 Wh · 1200 W output · LiFePO4 · $599
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
The C1000's smaller sibling. Same fast-charging DNA at a lower price, but the 768Wh capacity puts it firmly in weekend-trip territory.
Best for: Campers and van-lifers powering electronics, lights and a mini fridge — not home backup.
What we like
- 58-minute recharge at a sub-$600 price
- Five AC outlets is generous for this size
- Built-in LED light is genuinely useful for camping
Where it falls short
- 300W solar input is low — slow to top off off-grid
- 1600W surge rules out most motor-driven appliances
