The EcoFlow Delta 3 has the highest rated output of the three power stations compared here. EcoFlow and Jackery statements on medical use are included.
Heads up: some links here pay us. If you buy through an EcoFlow or eufy link we may earn a commission, at no cost to you (that's Awin, in some countries). Amazon and other shop links pay us nothing right now. I haven't tested these products myself unless the page says so; the picks come from the specs and listings, and I'll tell you when I'm not sure.

EcoFlow Delta 3
On published specifications the EcoFlow Delta 3 has the highest rated output of the three power stations compared here: 1800W continuous and 1024Wh, with EcoFlow extra batteries up to 5kWh according to EcoFlow. The Jackery Explorer 1000 v2 lists 1500W and 1070Wh. The Bluetti EB3A lists 600W and 268Wh and has been discontinued by Bluetti. Compare each unit's rated output and watt-hours with the rated draw in your own device's manual. The makers' own statements on medical use: EcoFlow says its power stations are not intended to power life-sustaining medical equipment, and Jackery says its power stations are not recommended for use with medical devices or life-support equipment. Confirm with your device's maker before use.

How This Was Researched
We compare specifications published by the makers: continuous output, watt-hours, charging, expandability, and the output waveform where the maker states it. We have not tested these units with any medical device and make no claim that they are suitable for one. EcoFlow prices were read from its stores on 2 October 2026. Statements attributed to a maker are the maker's own.
Frequently Asked Questions
EcoFlow says its power stations are not intended to power life-sustaining medical equipment, including hospital-grade CPAP devices, and advises confirming compatibility with the device maker or your healthcare provider. Jackery says on its product page that its power stations are not recommended for use with medical devices or life-support equipment. Bluetti's EB3A product page says nothing on medical use. These are the makers' statements, not ours.
Compare the continuous output in watts and the watt-hours the maker lists with the rated draw in your own device's manual. Runtime is roughly watt-hours divided by the load in watts, before conversion losses. Also check whether the maker states the output waveform and whether it states a position on medical use.
The EcoFlow Delta 3 lists 1800W continuous (2200W in X-Boost mode). The Jackery Explorer 1000 v2 lists 1500W and the Bluetti EB3A 600W (1200W surge).
EcoFlow's US spec sheet for the Delta 3 and Jackery's product page for the Explorer 1000 v2 do not state it. Bluetti's page lists the EB3A as a pure sine wave inverter.
