Does this Solar Battery Charger Really work?
We had the same question when we received our first shipment of these Solar chargers…. so we put it to the test. You can see the details in our video above. We have also put the findings below in 30 minute increments. It is important to note that we are in Florida so we do have a lot of sunlight. We started this test and did not know that the weather was not great. So we think that it was a pretty accurate test of the Solar Battery Charger’s capabilities in a real world circumstance.
Solar Panel charge time for Battery:
9:30 am- We hooked up the battery to the solar charger and placed it on top of our vehicle in front of the office. Placed the battery under the panel to keep it in the shade.
10:00 am- Checked the battery and it was already at 34% charge with minimal solar overcast from clouds.
10:30am- The Battery had stopped charging at 40% because one of the panels had blown shut in the breeze which shut down the charging. Reopened the panel and charging restarted immediately. Not sure how long the panel was closed so not a great indication on this 30 minute increment.
11:00 am- Much lower sunlight due to building clouds and battery is at 42% charge.
11:30 am- 52% charge and pretty heavy overcast clouds. Pulled the battery and solar charger inside while at lunch, and will continue after lunch time. It continued to rain so we had to restart charging at 10 am the next day.
10:00 am (following day)- 50% starting the charge again.
10:30 am- Battery was at 55% charge.
11:00 am- Battery was at 68% and in really full sunlight.
11:15-Battery was at 75%, had to pull it inside due to rain….again.
10:00 am (following day) battery was at 75%
10:30 am- Battery at 90% and in good sunlight
11:00 am- Battery at 95% and in good sunlight
11:45 am- Battery was at 100% charge and we were done.
Overall, I would say that this was a pretty “as-expected” performance of this Solar Charger. It started off charging very quickly and then really started to slow down on the second half of the charge (in very mixed conditions). This concerned me until I compared it to recharging the battery via a typical wall AC outlet. It recharged from the AC outlet in a very similar way. We probably should have checked the weather prior to starting the charge on the first day, because the tale end of Tropical Storm Ida was coming through and we got a lot of clouds and then about 14 hours of rain on day one. The second morning was a lot better to start with but ended up the same. It took a 3rd morning of charging before we were able to get the 100% charge. All that being said in a mixed sunlight condition the Solar Panel charged the battery in about 5 hours total. It gave a pretty good “real-world” understanding of what you can expect in mixed conditions. If you had 5 hours of full sunlight you can expect to be able to recharge your Portable Outlet CPAP Battery fully.
