CPAP power guide
Compare capacity, portability and documented AC or DC connections. Actual runtime depends on the specific CPAP, settings and accessories, so WattSift does not publish unsupported night estimates.

Why choose it Every relevant specification is documented for this unit: 1,070 Wh, 1,500 W continuous, 3,000 W surge and 23.8 lb.
Watch out for Not expandable, and at 23.8 lb it sits between the ultralight and mid-size options here.
Jackery
Best Compact CPAP Option
Why choose it 640 Wh at 14.1 lb - the compact option sitting between the 512 Wh and 1,024 Wh units here.
Watch out for 500 W continuous and no documented surge figure keep it firmly in device-class loads.
Why choose it 1,024 Wh and 1,800 W continuous at the simplest DELTA 3 configuration.
Watch out for Not expandable, so capacity stays fixed at the base unit.
Why choose it 1,024 Wh / 1,800 W with the higher 1,500 W AC recharge input in the DELTA 3 family - quick turnaround between locations.
Watch out for 27.6 lb - a travel case rather than a bedside unit.
Why choose it 10.4 lb and 286 Wh - the lightest unit here by a wide margin.
Watch out for 286 Wh is the smallest capacity here - device-class loads rather than appliances.
Why choose it 2,048 Wh - the largest capacity in this CPAP set.
Watch out for 44.8 lb - a stationary bedside configuration rather than something you carry.
Why choose it 1,024 Wh / 1,800 W at 25 lb, and it accepts expansion batteries so capacity can grow past the base unit.
Watch out for Maximum expanded capacity is not published; car-charging capability is not documented.
Why choose it 512 Wh and 1,000 W continuous in just 16.1 lb - the lightest unit here that still carries full 1,000 W output.
Watch out for UPS/EPS support and surge output are both undocumented for this model, so switchover behaviour and motor-start headroom cannot be stated.

A humidifier or heated hose can increase consumption. Do not reuse a runtime estimate from a different setup.

FAQ
It depends on measured device consumption and the full setup; no universal night count is reliable.
Yes, humidification and heated hoses can increase energy use.
Use the connection approved for your device and account for conversion losses.
No. These are general portable power stations, not dedicated medical batteries.
Camping use may be practical; airline battery restrictions usually rule out larger stations.
