CPAP battery solar charging question
I purchased a Pilot 12 Plus battery to use with my CPAP machine while off grid. I’m thinking of getting a Colman 55W solar kit to top up the battery while on 2/3 night camping trips. I don’t know much...

Sun power makes a portable 40W solar kit that claims to charge the battery in 4-5 hours.
A 40w panel will produce maybe 32w on a good day. That will put about 2.5a into the battery at peak production. In 5 hours that would be 12.5amp-hours. That means your 100ah battery could only be discharged 12% for that claim to be true.
You can't go by these mfr claims, or product reviews, or testimonials.
