The numbers
| Battery capacity | 1516Wh (NMC) |
|---|---|
| Usable energy | 1395Wh (92% via 12V/USB DC output) |
| Continuous AC output | 2000W |
| Surge rating | 3500W |
| Wi-Fi router and modem running watts | 20W |
| Startup watts | 20W |
| Average draw | 20W |
| Estimated runtime | 2.9 days |
| Energy per day of typical use | 480Wh |
1516Wh × 0.92 = 1395Wh usable ÷ 20W average = 69.7 hours

Recharging with solar
The Goal Zero Yeti 1500X accepts up to 600W of solar input. In real conditions that harvests about 2.3 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A Wi-Fi router and modem uses about 480Wh a day at 24 hours of use, so with enough panels and good sun the Goal Zero Yeti 1500X can run it indefinitely.
Tips
- Keeping internet up during an outage costs very little power, as long as your ISP's equipment down the street still has power too.
- Running it from the Goal Zero Yeti 1500X’s DC port instead of the AC outlet avoids inverter losses: about 106Wh more usable energy.
- The Goal Zero Yeti 1500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
