A router, modem, laptop and one monitor draw roughly 150 W, so a 1,000 Wh power station covers about 5–6 hours by our calculation; a unit with fast switchover (a UPS function) keeps equipment from rebooting when the grid drops.
The load
| Item | Typical watts |
|---|---|
| Router and modem | 25 |
| Laptop and charger | 60 |
| External monitor | 35 |
| Desk lamp (LED) | 10 |
| Phone chargers (2) | 20 |
UPS function
Some power stations list a switchover time (for example under 10 ms) when mains power fails, so a router or desktop does not reboot. Check the specification and the maker's wording: not every unit is rated for this, and some caution against using it for sensitive equipment.
Remember the line outside
Your internet provider's equipment outside the house may also lose power in a widespread outage. A phone hotspot on a charged battery is a useful second path.
