Medical equipment: these are estimates. Test your own setup and keep a backup plan.
The numbers
| Battery capacity | 1516Wh (NMC) |
|---|---|
| Usable energy | 1289Wh (85% via AC outlets) |
| Continuous AC output | 2000W |
| Surge rating | 3500W |
| CPAP with humidifier running watts | 60W |
| Startup watts | 60W |
| Average draw | 60W |
| Estimated runtime | 21 hours |
| Energy per day of typical use | 480Wh |
1516Wh × 0.85 = 1289Wh usable ÷ 60W average = 21.5 hours

Check the label on your CPAP with humidifier and enter its real wattage.
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 CPAP with humidifier uses about 480Wh a day at 8 hours of use, so with enough panels and good sun the Goal Zero Yeti 1500X can run it indefinitely.
Tips
- The heated humidifier roughly doubles a CPAP's power draw. Turning it down or off is the easiest way to get more nights per charge.
- You’ll still have about 1940W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Goal Zero Yeti 1500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.

FAQ
Will the Goal Zero Yeti 1500X run a CPAP with humidifier overnight?
Yes. Eight hours uses about 480Wh, roughly 37% of the Goal Zero Yeti 1500X’s usable capacity.
How long does the Goal Zero Yeti 1500X take to recharge with solar?
With its maximum 600W of solar input it refills in about 3.4 hours of strong sun. With a single 200W panel, expect about 2 sunny days (10 hours of full sun).
Is the Goal Zero Yeti 1500X safe for medical equipment?
These are estimates, not medical advice. Check your device’s actual power draw, test your setup before you rely on it, and always keep a backup plan approved by your doctor or equipment supplier.
