A 1000Wh (1 kWh) portable power station is the most popular size for apartment backup — big enough to matter during a blackout, small enough to live under a desk. But “what can it actually run, and for how long?” is the question that decides whether 1000Wh is right for you.
The short answer
A 1000Wh unit comfortably runs a renter’s core outage kit — Wi-Fi router, modem, a laptop, phone, and a lamp (about 50–80 W combined) — for roughly 11–18 hours. It can also run a mini fridge for most of a day, or a 55″ TV for 7–10 hours. What it cannot do is run high-heat appliances (space heater, hair dryer) for more than ~40 minutes.
What a 1000Wh power station runs — and for how long
| Device | Typical draw | Runtime on 1000Wh* |
|---|---|---|
| Wi-Fi router + modem | 15–25 W | ~34–55 hrs |
| Laptop | 30–60 W | ~14–28 hrs |
| Phone charge | ~10 Wh each | ~80 charges |
| Mini fridge (cycling) | 50–80 W avg | ~11–17 hrs |
| CPAP (no humidifier) | 30–40 W | ~21–28 hrs |
| 55″ LED TV | 80–120 W | ~7–10 hrs |
| Microwave | 1000 W | ~45 min |
| Space heater | 1500 W | ~35 min |
*Based on ~85% usable capacity (inverter losses). Real fridge runtime is often longer because compressors cycle on and off.
The best 1000Wh-class units for apartments
If 1 kWh is your size, these are the three we recommend for renters — all LiFePO4, all quiet enough for indoor use:
Bluetti AC180 (1152Wh)
The most apartment-shaped 1 kWh unit: 1800 W output, sub-20 ms UPS passthrough, and 0–80% recharge in ~45 minutes.
EcoFlow DELTA 2 (1024Wh)
Lighter (12 kg), 6 AC outlets, and expandable to 3 kWh with an add-on battery if your needs grow.
Anker SOLIX C1000 (1056Wh)
The quietest 1 kWh unit we know of — the fan stays off below ~350 W draw, ideal for overnight bedroom use.
How to estimate runtime yourself
Use this formula: Runtime (hours) = (1000 × 0.85) ÷ device watts. So a 60 W laptop = 850 ÷ 60 ≈ 14 hours. Add up the watts of everything you’ll run at once, then divide. Full walkthrough in our power station sizing guide.
Frequently asked questions
Is 1000Wh enough for a power outage in an apartment?
For most metropolitan outages (4–12 hours), yes. A 1000Wh unit keeps your internet, devices, and a light running comfortably, with capacity to spare. For multi-day outages or a full-size fridge, step up to 1500Wh+.
Can a 1000Wh power station run a refrigerator?
It can run a small/mid apartment fridge for roughly 11–17 hours, as long as the unit’s surge rating clears the compressor start (1200 W+). Full-size fridges drain it faster.
How long does a 1000Wh unit take to recharge?
From a wall outlet, the fastest 1 kWh units reach 80% in 45–60 minutes. Solar adds 3–6 hours depending on panel size.
