How long will the Jackery Explorer 300 v2 run a Wi-Fi router + cable modem?

About 10 hours from a full charge. A Wi-Fi router + cable modem averages about 25 W, and the 288 Wh battery gives about 245 Wh after inverter losses. That is 10% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 275 W more of the 300 W output. Each thing you add shares the same battery, so the 10 hours 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), more than the 245 Wh the Jackery Explorer 300 v2 can deliver, so plan to recharge every 10 hours.
