Looking for a battery pack

I'm needing a battery pack for my cpap, my sig should have which one I use, I don't use the humidifier accept in winter so one that can power that too isn't a big deal. I want one for like when I go camping or sometimes at work. IWhen storms come in power goes out pretty quick and for long periods in Downtown Dothan.)

Thanks
