What size power station do I need?

How portable power station sizing works

Power stations are sized two ways: watt-hours (Wh) of battery capacity, and watts of output. Multiply each device’s wattage by how many hours you’ll run it, add them up, and pad ~20% for conversion losses — that’s your Wh. Then make sure the station’s continuous output rating (in watts) is higher than everything you’d run at the same time. LiFePO4 batteries last far longer than standard lithium if you’ll cycle it often.
