What Size Power Station Do I Need for a Power Outage?
Power outage preparation is about knowing your essential loads and how long you need to cover them. This page gives you preconfigured outage scenarios — from a brief 4-hour blackout to a 48-hour extended outage — so you can quickly estimate the right battery size.
For a 4-hour outage covering essentials (fridge, Wi-Fi, lights, phones), 500–1,000 Wh is often enough. For 8 hours, 1,000–2,000 Wh. For 24+ hours, 2,000–3,000+ Wh or an expandable system with solar. Use the duration buttons below to calculate for your scenario.

Cerințe tipice de putere
| Specificație | Interval tipic |
|---|---|
| Putere de funcționare (W) | 200–500 W |
| Pornire (surge) | 600–1500 W |
| Scenariu implicit de autonomie | 8h |
Acestea sunt intervale de planificare. Pentru cel mai precis rezultat, verifică eticheta aparatului sau specificația producătorului și introdu puterea reală în calculatorul de mai sus.
Considerente cheie
- Priorities during an outage: keep food cold (fridge/freezer), maintain communication (phones, Wi-Fi), provide lighting, and power essential medical equipment (CPAP, etc.).
- For 24+ hour outages, a single portable station is unlikely to be enough without solar recharge. Consider an expandable system or a station with high solar input.
- If you have medical equipment (CPAP, oxygen concentrator), prioritize it in your load calculation and add margin. Consult your equipment manufacturer for backup power guidance.
- Don't forget that a fridge doesn't need to run continuously — with the door closed, a full fridge stays cold for about 4 hours without power. You can stretch battery life by letting the fridge cycle naturally.
Exemple de autonomie
About 3.3 hours of running everything at once. For a 4-hour outage, this is tight but workable with fridge cycling. For 8 hours, you need 2,000+ Wh.
About 6.6 hours of simultaneous running, or 8–10 hours with fridge cycling. Good for most 8-hour outages.
Considerente solare
- For 24+ hour outages, solar is the difference between a one-time backup and ongoing capability. A 400 W array can replace daily essential-load energy in good sun.
- If outages in your area are often caused by storms, remember that storm conditions reduce solar output — size your battery for cloudy-day scenarios.

Considerente de cumpărare
- For short outages (4–8h), a 1,000–2,000 Wh station is sufficient for essentials. Prioritize continuous output (600+ W) to handle the fridge surge.
- For 24+ hour outages, look at expandable systems (2,000–3,000+ Wh base) with 400+ W solar input.
- A UPS feature (automatic switchover) is valuable for outage prep — the station kicks in instantly when the grid drops.
