To power Resmed Airsense s11, what power cord should i buy?

I purchased it to power Resmed Airsense S10 CPAP. It does not work. I have not used it for any other purpose.

Can you recommend a portable solar solution for these batteries?

I had purchased to run "Resmed AirSense 10 Autoset" CPAP machine. But the machine does not start. with this battery. So, I have not used it further.
