Frequently Asked Questions

How many watt-hours do I need for home backup?
For essentials (fridge, lights, phone charging): 1,500–2,000Wh lasts about 8–12 hours. For extended backup including a router and medical devices: 3,000–5,000Wh. For whole-home backup: 5,000Wh+ or an expandable system.
Can a portable power station power my whole house?
A single unit cannot power a whole house, but high-capacity systems like the EcoFlow DELTA Pro (with expansion batteries up to 25kWh) or Bluetti AC300 can power essential circuits for an extended period. Some systems integrate with home panels for automatic backup switching.
Is a portable power station better than a generator for home backup?
Portable power stations are quieter, produce no fumes, require no fuel, and can be used indoors. Generators provide unlimited runtime with fuel but are noisy and must be used outdoors. For most urban and suburban homes, a power station is the better choice for short-term outages.
