Overall Feedback:
68% positive
80% were satisfied with the input voltage range, but 20% disagreed
The user mentioned that the charger was able to put out good voltage even in non-optimal conditions like shade or cloudy.
The user mentioned that the voltage should not exceed 14.7V when fully charged.
The reviewer mentioned that the charger had over 20 volts when not under load, which is higher than the acceptable voltage range for charging the charger itself.
82% praised the built-in safety features, but 18% experienced issues
The user expected the solar charger to have a battery protection built in, but still saw overvoltage, which is too much for a 12V car/motorcycle battery. This indicates that the charger may not have adequate safety features.
76% liked the portable design
The user mentioned that he has suction cupped the charger to the outside of RV and it has been through some nasty weather lately and it has not fallen off.
79% found it compatible with various devices
The user mentioned that the charger works through the cigarette lighter or supplied alligator clips, making it versatile.
74% were impressed with the fast charging speed, while 26% weren't
The user tested the charger with a Fluke meter and found that it puts out 18 volts.
The user mentioned that the charging rates of the two solar chargers were between 19 and 20 volts in varying sunlight.
The user has mentioned that the battery charger is charging the battery at a higher voltage than it should, which can lead to bad consequences. This shows negative sentiment towards the feature: Charging Speed.
The user mentioned that the old charger took over 12 hours to show a 'green' fully charged battery, but this charger showed fully charged in just 3 hours.
The battery was charged up to 100% usage in about 5 hours without any intervention.
