⛺
300-600Wh. Charge phones, run a light, maybe a small fan. Under $400.
🚙
1000-2000Wh. Run a fridge, laptop, lights all day. Pair with 200W+ solar.
🏠
2000-5000Wh. Keep fridge, router, and lights running through a 6-12 hour outage.
💻
500-1000Wh. Laptop + monitor + hotspot for a full work day off-grid.
