Battery backup question

[Tampa Jim]

In looking at Jackery units, solar panels, etc, my main question is:

what amps/watts is the minimum we would need for ye average cpap IF cpap is the only draw?

Amazon currently has the Jackery 1000V2 on sale, for Black Friday, @ $349.00.
Should easily run most CPAP units for over a week, fully enabled, even 110V.
Capacity of 1070Wh, recharge from 0-100% in an hour. IMO, no need for solar.
