How Much Power Does a Router and Modem Use?
Typical usage:
- Router → 5–15W
- Modem → 5–10W
👉 Combined usage is usually very low.
What Size Power Station Do You Need?

Recommended Setup
- 300–500Wh
👉 Even small power stations can provide extended internet backup.
How Long Will It Run?
Example:
20W × 24 hours = 480WhTypical Runtime
- 300Wh → 10–15 hours
- 500Wh → 20+ hours
👉 Actual runtime depends on equipment and usage.

Frequently Asked Questions
Will internet still work during an outage?
Usually yes, if your provider’s local infrastructure remains powered.
Is a small power station enough?
Yes, networking equipment uses very little power.
Can I use a UPS instead?
Yes, but runtime is usually much shorter.
Final Thoughts
Portable power stations are an excellent solution for maintaining internet access during outages.
Because routers and modems use very little power, even compact systems can provide long runtime and reliable connectivity.
