How long will an EcoFlow RIVER Pro run a Starlink (standard dish)?
About 5.8 hours — 5 h 50 min typically, from 5 h 29 min in the worst case to 6 h 11 min at best. That assumes a Starlink (standard dish) pulling 75 W continuously, plus the station's 10 W AC mains socket overhead — 85 W in total out of 496 usable watt-hours.
Idles near 45 W and spikes when the dish heats itself in snow — the heater is what empties batteries in winter.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × Starlink (standard dish), UK 230 V | 85 W | 5 h 29 min | 5 h 50 min | 6 h 11 min |
| 2 × Starlink (standard dish), UK 230 V | 160 W | 2 h 55 min | 3 h 6 min | 3 h 17 min |
| 1 × Starlink (standard dish), US 120 V | 85 W | 5 h 29 min | 5 h 50 min | 6 h 11 min |
- 0.7 nights of eight hours, or 0.24 days of continuous running.
- Usable energy: 496 Wh of the 720 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 2,807 Wh of rated capacity — 3.9× this station.
- Start-up: the Starlink (standard dish) asks for 180 W at switch-on against this station's 1,200 W peak — comfortable.

If this is for a power cut
In a power cut the router often matters most: it carries the internet and, on a digital landline, the home phone.
Without a power station: a 20,000 mAh power bank runs a Wi-Fi router for about 5 h. See the power bank numbers.
Mini UPS for the router. Home phones now run through the broadband router, so when it goes off in a power cut the landline goes with it. A small battery box keeps the router, and the phone plugged into it, working.
Look for: DC outputs that match the voltage printed on your router's power adapter (usually 12 V), enough of them for the fibre box too if you have one, and a capacity in watt-hours.
Power bank, 20,000 mAh. Keeps a phone going for days if you use it sparingly.
Look for: Capacity in watt-hours as well as mAh (about 74 Wh for 20,000 mAh), USB-C in and out, and keep it charged.
Simple mobile phone. A basic mobile with a week of standby is the backup when the home phone dies with the router. Easy to use, and it stays charged far longer than a smartphone.
Look for: Large buttons, a loud ringer, a long stated standby time, and an emergency button if it will be used by someone who lives alone.
