What the DELTA 2 can run
Estimated runtime on a full charge with one appliance plugged in. We assume 80% to 90% of the rated 1,024 Wh reaches the appliance. The start-up check compares each appliance's published start-up figure (volts times starting amps, in VA) with the stated surge rating. At small loads the station's own idle draw takes a large share, so actual runtime can fall well below the range.

Medical devices. A rating check is not medical advice; here is what device makers and the FDA say.
- CPAP without humidifier (ResMed AirSense 10/11 class): FDA: ask your device maker or supplier whether the device can run on batteries or a generator, and check settings after power returns. If the device is life-sustaining, seek emergency help. ResMed battery guide: it strongly recommends a ResMed DC-to-DC converter over a DC-to-AC inverter when running from a battery.
- CPAP with heated humidifier (ResMed AirSense 11 / 10): FDA: ask your device maker or supplier whether the device can run on batteries or a generator, and check settings after power returns. ResMed battery guide: it strongly recommends a ResMed DC-to-DC converter over a DC-to-AC inverter when running from a battery.
- Travel CPAP (ResMed AirMini): FDA: confirm with the maker or supplier that battery or generator power is suitable for your device.
- Home oxygen concentrator (5 LPM): FDA: ask the maker or supplier whether it can run on batteries or a generator, and use battery-powered lights rather than gas lights or torches when oxygen is in use. Seek emergency help if the device is life-sustaining.
- Nebulizer (compressor type), Power wheelchair or scooter charger (24 V, 8 A): FDA: ask your device maker or supplier whether the device can run on batteries or a generator, and check settings after power returns. If the device is life-sustaining, seek emergency help.
Charging: wall, solar and car
- Wall charging: up to 1,200 W; fastest stated full charge 72 min.
