What Size Power Station to Run an Apartment for 24 Hours?

“What size power station do I need to run my apartment for a full day?” It is the right question — and the answer depends entirely on whether you include the fridge. Here is the real math.

The short answer

To run apartment essentials (internet, phones, laptop, lights, a fan) for 24 hours, you need about 1.2–2 kWh — a single 1 kWh unit covers it with light use. Add a fridge and you are at ~3 kWh/day, which means an expandable system or solar. Our pick: the Bluetti AC180 for essentials, or the expandable EcoFlow DELTA 2 if a fridge is in the plan.

24-hour load profiles

What you run Energy / 24 hrs Unit needed
Internet + phones + laptop ~0.6–1 kWh 768 Wh–1 kWh
+ lights + a fan ~1.2–2 kWh 1 kWh (light use) to 2 kWh
+ a fridge ~2.5–3 kWh Expandable / 3 kWh

The fridge is the swing factor — it roughly doubles your daily need. For a fridge-included 24 hours, pair an expandable unit with an add-on battery, or recharge midday with solar.

Frequently asked questions

What size power station runs an apartment for 24 hours?

~1.2–2 kWh for essentials; ~3 kWh if you include a fridge. A 1 kWh unit covers essentials with light use.

Can a 1kWh unit last a full day?

Yes for internet, devices, and lights. Not if you add a fridge — that needs an expandable system or solar top-up.

How do I extend to multiple days?

Add an expansion battery or a 200–400 W solar panel to recharge during the day.
