Remote Work Blackout: Keeping Zoom Alive When the Grid Dies (UPS vs. Generator)

The "Flicker" Problem: Why Generators Fail Remote Workers

If you rely on a gas generator or a portable power station without "EPS" (Emergency Power Supply) mode, you will lose internet. The switchover time of 30ms is enough to reboot your modem. You need 0ms transfer time. This requires a dedicated Mini-UPS (Uninterruptible Power Supply) for your network gear.

Wattage Math: Modem + Router + ONT

Most fiber setups draw surprisingly little power. A standard Fiber ONT (Optical Network Terminal) + Eero Mesh Router draws approx 18-25 Watts. A massive 1000Wh battery is overkill. You need efficiency.

Test Results: 8-Hour Workday Simulation

Device Runtime (20W Load) Transfer Time Beep Disable?
EcoFlow River 2 ↗ 10.5 Hours 30ms (Might drop VPN) App Control
CyberPower 1500VA UPS ↗ 45 Minutes 0ms (Instant) Button Press
Generic Mini-UPS 2.1 Hours 0ms No (Beeps loudly)

The "Hybrid" Strategy

The pro move is to plug your Modem/Router into a small UPS (like the CyberPower) to handle the 0ms switchover, and then plug that UPS into a larger EcoFlow generator for long-term power. This gives you instant protection + infinite runtime.

How much power does your desk use?

Laptops + Monitors + Routers add up. Check your total wattage.
