Thank you for your question. Yes — the Jackery Explorer 290 (E290) can be used to power a portable oxygen machine, as long as the oxygen device’s power draw stays within the unit’s limits. 🔌 E290 Key Specs • Battery Capacity: ~292 Wh • AC Output: 200 W continuous, 400 W surge • Voltage/Frequency: 110 V, 60 Hz 📊 Typical Runtime (Estimate) Portable oxygen machines usually draw well under 200 W, so the E290 can power them. Estimated runtime (approximate): If your machine draws ~50 W: ~4 hours If it draws ~75–100 W: ~2–3 hours Actual runtime varies based on the actual wattage and how often the device cycles. 👍 Notes • The E290’s AC output is pure sine wave, compatible with medical devices that require stable power. • For longer runtime, solar charging or periodic recharging is recommended. If you tell me your portable oxygen machine model or its actual wattage, I can give you a more precise estimate!
