What size power station do I need to make coffee and run electronics during an outage?
A drip coffee maker plus the usual electronics is a good lesson in how power stations handle mixed loads: the coffee maker is a brief 900W spike that dominates the surge number, while the electronics are the steady draw that actually determines runtime.
The load
- Coffee maker (drip) — 900W running
- Wi-Fi router + modem — 15W running
- Laptop — 65W running
- Phone charger — 10W running
Field note: Brew first, then work — the coffee maker's heating element is a short, heavy pull, so let it finish before you lean on the station for the rest of the morning. A midsize station handles the surge and still leaves hours for the laptop and router. A French press sidesteps the biggest load entirely.
Right size: Expandable home backup (≈6,000Wh+) · 5,000W
Backing up whole circuits through a transfer switch; add battery modules for days of autonomy, especially with solar. A home-backup system, not a grab-and-go unit. For 240V loads or true whole-home coverage, compare against a standby generator.

Adjust for your setup
Different loads or runtime? Uncheck and re-check below and drag the runtime slider — the plate recomputes live.
Capacity includes inverter loss (~15%) and a usable-charge margin, so the station isn't run flat. A solar panel or vehicle charge extends runtime past this number.
