What size power station do I need for camping versus home backup?

For weekend camping, phone/laptop charging, and small appliances, a 300Wh to 1,000Wh unit is usually plenty and easier to carry. For home backup that needs to ride out outages or run larger loads, look at 2,000Wh and up, ideally with expandable battery options and a high continuous AC output (3,000W or more, and 120V/240V if you want to back up a panel).
