I have tested them with a multimeter and they do put out what they claim.
Unfortunately it is not enough to keep the battery charged due to the parasitic nature of components in each vehicle over time. Even directly clipped to the battery and not the lighter socket.
Example, Just finished one month stay at the beach, VW , panel on dashboard all the time clipped directly to battery FULL SUN. at the end of the month battery tested only 70%.
Chevy at home, same thing, solar panel on dash clipped directly to battery, 70% battery charge when we got back home. Each started out 100% charged with a computerized charger plugged into wall outlet.
Batteries are 1 yr old in both vehicles. And I keep them on a electric maintainer charger all the time.
2.4w / 12.5V = 19mA
Just enough to overcome the 14mA draw on the vehicle battery.
Installed in an old s-10 truck that does not get much use. I "RTV" glued it to the dash.
The storage building is 50-75 feet from electricity. I did not want to string an extension cord across my yard all winter.
I have used this unit for a couple years and it does a fine job.
I am glad I purchased this charger.
I tried testing them in direct sunlight by connecting a volt tester to them. Both chargers did not show power coming from the charger. The ad says this charger will charge inside with sunlight from a window and on cloudy days.
