Watts or watt-hours?

Watts (W) tell you what a power station can run at one moment. Watt-hours (Wh) tell you how long it lasts. A 2,000 W station with 2,000 Wh runs a 100 W load for about 17 h, or charges a phone about 113 times.

What to know about this size

2,000 W covers almost every plug-in appliance in a US home, including a microwave, coffee maker or 1,500 W space heater. Just not all at once.
The battery is now the limit: a space heater on high empties 2,000 Wh in about 1.4 h, while a fridge runs for about 30.9 h.
It won't power a whole home: central AC, electric ovens, dryers and water heaters need 240 V or far more power.
