How long will the DJI Power 2000 run a Wi-Fi router + cable modem?

About 3 days from a full charge. A Wi-Fi router + cable modem averages about 25 W, and the 2,048 Wh battery gives about 1,741 Wh after inverter losses. That is 1.4% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 2,975 W more of the 3,000 W output. Each thing you add shares the same battery, so the 3 days for a Wi-Fi router + cable modem gets shorter.

How much of the battery does a Wi-Fi router + cable modem use in a day?

About 600 Wh a day (25 W × 24 hours), 34% of the 1,741 Wh the DJI Power 2000 can deliver.
