What matters in this category

Some medical devices are sensitive to waveform quality. Pure sine wave output is recommended for CPAP machines and oxygen concentrators to avoid motor interference or alarm triggers.
Runtime matters more than peak power. A CPAP at 56W needs 450+ Wh for a full night, but most stations lose 30% to inverter inefficiency.
For life-critical equipment, consult the device manufacturer about portable power compatibility before relying on it during an outage.

How to choose for Medical

Start with battery capacity, not wattage. Medical devices draw modest power but run for 8-12 hours straight. A station with 500+ Wh and pure sine wave output covers most CPAP and nebulizer setups. For oxygen concentrators, you need higher wattage (300-600W continuous) and may need 1,000+ Wh for overnight use. Always check the device manual for power quality requirements.

Common mistake

Buying based on peak output instead of battery capacity. A 2,000W station with 500Wh runs a CPAP for one night, but a 1,000W station with 1,000Wh runs it for two.
