The solar panel connected just as instructed in the documentation to the Freedom battery, charged the battery from 34% to 100% in about 4 hours. I may not have had the solar panels at the right angle for max charging, but all was great.
Keep your CPAP Battery charged up and ready to go using the power of the sun! The Freedom 50W Solar Panel allows you to safely and efficiently charge your favorite external batteries (like the Freedom CPAP Battery & Freedom V2 CPAP Battery) and other small portable electronics (like cell phones and tablets) that operate from 13.2V or less using the power of the sun.
Charge times will vary depending upon the amount of direct sunlight that hits the solar cells.
Optimal charging conditions include: direct sunlight with the panels angled toward the sun, no clouds, no hanging branches or obstructions to sunlight, no shade covering any of the panels, and no dirt or debris on the solar cells.
In optimal charging conditions the Freedom™ CPAP Battery can be charged by the Freedom 50W Solar Panel in approximately 4 hours when the battery is fully discharged.
Charge times are per battery; therefore, it will take approximately 8 hours to charge two Freedom™ CPAP batteries simultaneously when the batteries are fully discharged.
Always conﬁrm the electronic device’s charging requirements are compatible with the Freedom 50W Solar Panel speciﬁcations before use!
Charge times will vary depending upon the amount of direct sunlight that hits the solar cells and the specific charging requirements of the device.
NOTE: The Freedom 50W Solar Panel may be used with both models.
