How long will a power station keep my Wi-Fi up?
A home router plus cable or fiber modem draws about 15 W, so a 499 Wh unit keeps the internet up for roughly 1.2 days and a 1 kWh unit for about 2.4 days. Your internet provider's equipment up the street also needs power, so it may drop before your battery does.
Runtimes by size
| Unit | Battery | Router and modem runtime | Price when checked |
|---|---|---|---|
| EcoFlow RIVER 3 Plus | 286 Wh | 16 hours | $279 |
| Goal Zero Yeti 500 | 499 Wh | 1.2 days | $500 |
| Goal Zero Yeti 700 | 677 Wh | 1.6 days | $700 |
| Bluetti Elite 100 V2 | 1,024 Wh | 2.4 days | $499 |
| EcoFlow DELTA 3 | 1,024 Wh | 2.4 days | $599 |
Notice the price column: the 1 kWh class currently costs about the same as the 500 to 700 Wh class and runs three to four times longer. Unless weight matters, skip the middle sizes.
Make it hands-off
Plug the router and modem into the power station, and the power station into the wall, with pass-through or UPS mode on. When the grid drops, the station takes over in milliseconds and your video call does not notice. Units with a true UPS mode (10 ms or faster) include the EcoFlow DELTA 3, Anker SOLIX C1000 Gen 2 and Bluetti Elite 100 V2.

Common questions
Will my internet still work in an outage?
Fiber usually does, since it carries no power. Cable often works for a few hours on the provider’s backup batteries. DSL depends on the phone company’s equipment. A phone hotspot is the fallback.
