Great Build Quality but not keeping my battery charged.
on March 21, 2017
Very good build quality with excellent cables and connectors, but like many have said, it won't keep up with my vehicle's battery drain. Maybe if it were bright summer sun everyday, but not every day is, and once the battery starts going down in voltage, this solar charger never gets it back to where it should be. Some reviewers blame that on the unit's LEDs that stay on all night, BUT those LEDs are only using .01 amps, going by my meter's measurement, or roughly .12 watts. My vehicle uses more than that when sitting idle, and you have to consider the fact that Lead Acid batteries lose roughly 1% per day even without vehicle drain, so you have to overcome that as well. In theory this unit should do the job, and I'd guess it does on a disconnected or isolated battery, but unfortunately isn't keeping up with battery drain in my case.
